工业机器人发展中英文资料外文翻译文献The development of industrial robotsIndustrial robot is a robot, it consists of a CaoZuoJi. Controller. Servo drive system and detection sensor device composition, it is a kind of humanoid operating automatic control, can repeat programming, can finish all kinds of assignments in three difficulties in authorship space the electromechanical integration automation production equipment, especially suitable for many varieties, become batch flexible production. It to stabilize and improve the product quality, raise efficiency in production, improve working conditions of the rapid renewal plays an extremely important role.Widely used industrial robots can gradually improve working conditions, stronger and controllable production capacity, speed up product updating and upgrading. Improve production efficiency and guarantee the quality of its products, eliminate dull work, save labor, provide a safe working environment, reduces the labor intensity, and reduce labor risk, improve the machine tool, reduce the workload and reduce process production time and inventory, enhance the competitiveness of enterprises.As technology advances, the development of industrial robot, the process can be divided into three generations -- generation, for demonstration reproduce, and it mainly consists of robot hand controller and demonstration teaching machines composed, can press advance box to record information guide action, the current industry repeated reappearance application of execution most. The second to feel robot, such as powerful sleep touch and vision, it has for some outside information feedback adjustment ability, currently has entered the application stage. Third generation of intelligent robot it has sense and understanding ability, in the external environment for the working environment changed circumstances, can also successfully complete the task, it is still in the experimental research phase.The United States is the birthplace of the robot, as early as in 1961, America's ConsolidedControlCorp and AMF companies developed the first practical demonstration emersion robot. After 40 years of development,the United States in the world of robotics has been in the lead position. Still Its technology comprehensive, advanced, adaptability is strong.Japan imported from America in 1967, the first robot in 1976 later, with the rapid development of the microelectronics and the market demand has increased dramatically, Japan was labor significant deficiencies in enterprise, industrial robots by "savior"'s welcome, make its Japanese industrial robots get fast development, the number of now whether robots or robot densities are top of the world, known as the "robot kingdom," said. The robot introduced from Germany time than Britain and Sweden about late 1956, but the Labour shortages caused by war, national technical level is higher social environment, but for the development and application of industrial robot provides favorable conditions. In addition, in Germany, for some dangerous prescribed, poisonous or harmful jobs, robot instead of ordinary people to the labor. This is the use of robots exploit a wide range of markets, and promote the development of the industrial robot technology. At present, the German industrial robots total of the world, which only behind to Japan.The French government has been more important robot technology, and through a series of research program, support established a complete science and technology system, make the development of the French robot smoothly. In government organization project, pay special attention to the robot research based technique, the focus is on the application research on in robot. And by industry support the development application and development of work, both supplement each other, make robots in France enterprises develop rapidly and popularize and make France in the international industrial machine with indispensable if position.British jamie since the late 1970s, promote and implement a department measures listed support the development of policies and make robots British industrial robots than today's robot powers started to early, and once in Japan has made the early brilliance. However, at this time the government for industrial robots implemented the constraining errors. This mistake in Britain dust, the robot industry in Western Europe was almost in the bottom of it. In recent years, Italy, Sweden, Spain, Finland, Denmark and other countries because of its own domestic robots market in great demand, development at a very fast pace. At present, the international on industrial robot company mainly divided into Japanese and European series. In AnChuan of Japanese are mainly the ethical products, the oTC, panasonic, FANLUC, not two more, etc. The products of the company kawasaki The main Asiatic KUKA, German CLOOS, Sweden's ABB, Italy CO work pelatiah U and Austria GM company.Industrial robot in China started in early 1970s, after 30 years development, roughly experienced three stages: in the 1970s and 1980s budding transplanter and the application of the 1990s initialization period. With the 20th century 70's world technology rapid development, the application of industrial robots in world created a climax, in this context, our country in 1972 start developing their industrial robots. Enter after the 1980s, with the further reform and opening, in high technology waves pound, our research and development of robot technology from the government's attention and support, "during the seventh state funds, thanked the parts were set robot and research, completed demonstration emersion type industrial robot complete technology development, developed spray paint, welding, arc welding and handling robot. , the national high technology research and development program begin to carry out, after several years research and made a large number of scientific research. Successfully developed a batch of special robot.From 9O 2O century since the early, China's national economy achieve two fundamental period of transformation into a a new round of economic restructuring and technological progress, China's industrial robots upsurge in practice and have made strides, and have developed spot welding, welding, assembling, paint, cutting, handling, palletizing etc various USES of industrial robot, and implement a batch of robot application engineering, formed a batch of industrial robots for our country industrialization base, the industrial robot soar laid a foundation. But compared with the developed countries, China also has the very big disparity of industrial robots.Along with the development of industrial robot depth and the breadth and raise the level of robot, industrial robots are has been applied in many fields. From the traditional automobile manufacturing sector to the manufacturing extensions. Such as mining robots, building robots and hydropower system used for maintenance robots, etc. In defense of military, medicine and health, food processing and life service areas such as the application of industrial robots will be more and more. The manufacturing of automobiles is a technology and capital intensive industry, is also the most widely used of industrial robots, accounting for almost to the industry for more than half of the industrial robots. In China, the industrial robot first is also used in automobile and engineering machinery industries. In car production of industrial robot is a major in the equipment, the brake parts and whole production of arc welding, spot welding, painting, handling, glue, stamping process used in large amounts. Our country is forecast to rise period, entered the automobile ownership in the next few years, car will still growing at around 15 percent annually. So the next few years the industrial robot demand willshow high growth trend, about 50% in growth, industrial robots in our automobile industry application will get a rapid development.Industrial robot in addition to the wide application of in the automotive industry in electronic, food processing, nonmetal processing, daily consumer goods and wood furniture processing industries for industrial robots demand is growing rapidly. In Asia, 2005 72,600 sets, installation industrial robots, compared with 2004 grew by 40%, and application in electronic industry accounted for about 31%. In Europe, according to statistics, since 2004 and 2005 in l: tI industry robot in the food processing industry increased 17% the application of left and right sides, in the application of nonmetal processing industry increased 20%, and daily necessities in consumption industries increased by 32% in wood furniture processing industry, up 18% or so. Industrial robot in oil has a wide application in, such as sea oil drilling, oil platforms, pipeline detection, refinery, large oil tank and tank welding etc all can use robots to complete. In the next few years, sensing technology, laser technology, engineering network technology will be widely used in industrial robots work areas, these technologies can cause the industrial robot application more efficient, high quality, lower cost. It is predicted that future robots will in medical and health care, biological technology and industry, education, relief, ocean exploitation, machine maintenance, transportation and agriculture and aquatic products applied field.In China, the industrial robot market share are mostly foreign industrial robots enterprise holds. Before the gunman in the international, domestic industrial robots enterprise facing great pressure of competition. Now China is from a "manufacturing power" to "manufacturing power forward," Chinese manufacturing industry faces and the international community, participate in the international division of labor in the great challenge of industrial automation increase immediate, government must can increase the funds for robots and policy support, will give the industry of industrial robots development into new momentum. With independent brand "devil robot" MoShi special technology company dedicated to providing solutions to the mainboard and robot, is willing with all my colleagues a build domestic industrial robot happy tomorrow!ReferencesElectronic Measurement and Intrumenttations,Cambridge University Press,1996工业机器人的发展工业机器人是机器人的一种,它由操作机.控制器.伺服驱动系统和检测传感器装置构成,是一种仿人操作自动控制,可重复编程,能在三难空间完成各种作业的机电一体化的自动化生产设备,特别适合于多品种,变批量柔性生产。

中英文对照资料外文翻译文献FEM Optimization for Robot StructureAbstractIn optimal design for robot structures, design models need to he modified and computed repeatedly. Because modifying usually can not automatically be run, it consumes a lot of time. This paper gives a method that uses APDL language of ANSYS 5.5 software to generate an optimal control program, which mike optimal procedure run automatically and optimal efficiency be improved.1)IntroductionIndustrial robot is a kind of machine, which is controlled by computers. Because efficiency and maneuverability are higher than traditional machines, industrial robot is used extensively in industry. For the sake of efficiency and maneuverability, reducing mass and increasing stiffness is more important than traditional machines, in structure design of industrial robot.A lot of methods are used in optimization design of structure. Finite element method is a much effective method. In general, modeling and modifying are manual, which is feasible when model is simple. When model is complicated, optimization time is longer. In the longer optimization time, calculation time is usually very little, a majority of time is used for modeling and modifying. It is key of improving efficiency of structure optimization how to reduce modeling and modifying time.APDL language is an interactive development tool, which is based on ANSYS and is offered to program users. APDL language has typical function of some large computer languages. For example, parameter definition similar to constant and variable definition, branch and loop control, and macro call similar to function and subroutine call, etc. Besides these, it possesses powerful capability of mathematical calculation. The capability of mathematical calculation includes arithmetic calculation, comparison, rounding, and trigonometric function, exponential function and hyperbola function of standard FORTRAN language, etc. By means of APDL language, the data can be read and then calculated, which is in database of ANSYS program, and running process of ANSYS program can be controlled.Fig. 1 shows the main framework of a parallel robot with three bars. When the length of three bars are changed, conjunct end of three bars can follow a given track, where robot hand is installed. Core of top beam is triangle, owing to three bars used in the design, which is showed in Fig.2. Use of three bars makes top beam nonsymmetrical along the plane that is defined by two columns. According to a qualitative analysis from Fig.1, Stiffness values along z-axis are different at three joint locations on the top beam and stiffness at the location between bar 1 and top beam is lowest, which is confirmed by computing results of finite element, too. According to design goal, stiffness difference at three joint locations must he within a given tolerance. In consistent of stiffness will have influence on the motion accuracy of the manipulator under high load, so it is necessary to find the accurate location of top beam along x-axis.To the questions presented above, the general solution is to change the location of the top beam many times, compare the results and eventually find a proper position, The model will be modified according to the last calculating result each time. It is difficult to avoid mistakes if the iterative process is controlled manually and the iterative time is too long. The outer wall and inner rib shapes of the top beam will be changed after the model is modified. To find the appropriate location of top beam, the model needs to be modified repetitiously.Fig. 1 Solution of Original DesignThis paper gives an optimization solution to the position optimization question of the top beam by APDL language of ANSYS program. After the analysis model first founded, the optimization control program can be formed by means of modeling instruction in the log file. The later iterative optimization process can be finished by the optimization control program and do not need manual control. The time spent in modifying the model can be decreased to the ignorable extent. The efficiency of the optimization process is greatly improved.2)Construction of model for analysisThe structure shown in Fig. 1 consists of three parts: two columns, one beam and three driving bars. The columns and beam are joined by the bolts on the first horizontal rib located on top of the columns as shown in Fig.1. Because the driving bars are substituted by equivalentforces on the joint positions, their structure is ignored in the model.The core of the top beam is three joints and a hole with special purpose, which can not be changed. The other parts of the beam may be changed if needed. For the convenience of modeling, the core of the beam is formed into one component. In the process of optimization, only the core position of beam along x axis is changed, that is to say, shape of beam core is not changed. It should be noticed that, in the rest of beam, only shape is changed but the topology is not changed and which can automatically be performed by the control program.Fig.1, six bolts join the beam and two columns. The joint surface can not bear the pull stress in the non-bolt joint positions, in which it is better to set contact elements. When the model includes contact elements, nonlinear iterative calculation will be needed in the process of solution and the computing time will quickly increase. The trial computing result not including contact element shows that the outside of beam bears pulling stress and the inner of beam bears the press stress. Considering the primary analysis object is the joint position stiffness between the top beam and the three driving bars, contact elements may not used, hut constructs the geometry model of joint surface as Fig.2 showing. The upper surface and the undersurface share one key point in bolt-joint positions and the upper surface and the under surface separately possess own key points in no bolt positions. When meshed, one node will be created at shared key point, where columns and beam are joined, and two nodes will be created at non shared key point, where column and beam are separated. On right surface of left column and left surface of right column, according to trial computing result, the structure bears press stress. Therefore, the columns and beam will share all key points, not but at bolts. This can not only omit contact element but also show the characteristic of bolt joining. The joining between the bottoms of the columns and the base are treated as full constraint. Because the main aim of analysis is the stiffness of the top beam, it can be assumed that the joint positions hear the same as load between beam and the three driving bars. The structure is the thin wall cast and simulated by shell element . The thickness of the outside wall of the structure and the rib are not equal, so two groups of real constant should he set. For the convenience of modeling, the two columns are alsoset into another component. The components can create an assembly. In this way, the joint positions between the beam core and columns could he easily selected, in the modifying the model and modifying process can automatically be performed. Analysis model is showed Fig.1. Because model and load are symmetric, computing model is only half. So the total of elements is decreased to 8927 and the total of nodes is decreased to 4341. All elements are triangle.3.)Optimization solutionThe optimization process is essentially a computing and modifying process. The original design is used as initial condition of the iterative process. The ending condition of the process is that stiffness differences of the joint locations between three driving bars and top beam are less than given tolerance or iterative times exceed expected value. Considering the speciality of the question, it is foreseen that the location is existent where stiffness values are equal. If iterative is not convergent, the cause cannot be otherwise than inappropriate displacement increment or deficient iterative times. In order to make the iterative process convergent quickly and efficiently, this paper uses the bisection searching method changing step length to modify the top beam displacement. This method is a little complex but the requirement on the initial condition is relatively mild.The flow chart of optimization as follows:1. Read the beam model data in initial position from backup file;2. Modify the position of beam;3. Solve;4. Read the deform of nodes where beam and three bars are joined;5. Check whether the convergent conditions are satisfied, if not, then continue to modify the beam displacement and return to 3, otherwise, exit the iteration procedure.6. Save the results and then exit.The program's primary control codes and their function commentaries are given in it, of which the detailed modeling instructions are omitted.

The total of lines is up to about 1000 lines. Many codes such as modeling and post-process codes are used repeatedly. To make the program construct clear, these instructions can he made into macros, which are called by main program. This can efficiently reduce the length of the main program. In addition, modeling instructions from log file includes lots of special instructions that are only used under graphic mode but useless under hatch mode. Deleting and modifying these instructions when under batch mode in ANSYS can reduce the length of the file, too.In the program above, the deformation at given position is read from node deformation. In meshing, in order to avoid generating had elements, triangle mesh is used. In optimization, the shape of joint position between columns and beam continually is changed. This makes total of elements different after meshing each time and then element numbering different, too. Data read from database according to node numbering might not he data to want. Therefore, beam core first needs to he meshed, then saved. When read next time, its numbering is the same as last time.Evaluating whether the final result is a feasible result or not needs to check the flag value. If only the flag value is I, the result is feasible, otherwise the most proper position is not found. The total displacement of top beam is saved in parameter step. If the result is feasible, the step value is the distance from initial position to the most proper position. The sum of iterative is saved in parameter 1. According to the final value of I, feasibility of analysis result and correctness of initial condition can he evaluated.4)Optimization resultsThe sum of iterative in optimization is seven, and it takes about 2 hour and 37 minutes to find optimal position. Fig.3 shows the deformation contour of the half-construct. In Fig.3, the deformations in three joints between beam and the three driving bars is the same as level, and the corresponding deformation range is between -0.133E-04 and -0.1 15E-O4m, the requirement of the same stiffness is reached. At this time, the position of beam core along x-axis as shown in Fig. 1 has moved -0.71E-01m compared with the original designed positionBecause the speed of computer reading instruction is much faster than modifying model manually, the time modifying model can be ignored. The time necessary foroptimization mostly depends on the time of solution. Compared with the optimization procedure manually modifying model, the efficiency is improved and mistake operating in modeling is avoided.5)ConclusionThe analyzing result reveals that the optimization method given in this paper is effective and reaches the expected goal. The first advantage of this method is that manual mistakes do not easily occur in optimization procedure. Secondly, it is pretty universal and the control codes given in this paper may he transplanted to use in similar structure optimization design without large modification. The disadvantage is that the topology structure of the optimization object can not be changed. The more the workload of modifying the model, the more the advantages of this method are shown. In addition, the topology optimization function provided in ANSYS is usedto solve the optimization problem that needs to change the topology structure.The better optimization results can he achieved if the method in this paper combined with it.中文译文:机器人机构优化设计有限元分析摘要机器人结构最优化设计,设计模型需要反复的修正和计算。

It should be said it is a common scientific and technological development of a comprehensive results, for the socio-economic development of a significant impact on a science and technology. It attributed the development of all countries in the Second World War to strengthen the economic input on strengthening the country's economic development. But they also demand the development of the productive forces the inevitable result of human development itself is the inevitable result then with the development of humanity, people constantly discuss the natural process, in understanding and reconstructing the natural process, people need to be able to liberate a slave. So this is the slave people to be able to replace the complex and engaged in heavy manual labor, People do not realize right up to the world's understanding and transformation of this technology as well as people in the development process of an objective need. Robots are three stages of development, in other words, we are accustomed to regarding robots are divided into three categories. is a first-generation robots, also known as teach-type robot, it is through a computer, to control over one of a mechanical degrees of freedom Through teaching and information stored procedures, working hours to read out information, and then issued a directive so the robot can repeat according to the people at that time said the results show this kind of movement again, For example, the car spot welding robots, only to put this spot welding process, after teaching, and it is always a repeat of a work It has the external environment is no perception that the force manipulation of the size of the work piece there does not exist, welding 0S It does not know, then this fact from the first generation robot, it will exist this shortcoming, it in the 20th century, the late 1970s, people started to study the second-generation robot, called Robot with the feeling that This feeling with the robot is similar in function of a certain feeling, forinstance, force and touch, slipping, visual, hearing and who is analogous to that with all kinds of feelings, say in a robot grasping objects, In fact, it can be the size of feeling out, it can through visual, to be able to feel and identify its shape, size, color Grasping an egg, it adopted a acumen, aware of its power and the size of the slide. Third-generation robots, we were a robotics ideal pursued by the most advanced stage, called intelligent robots, So long as tell it what to do, not how to tell it to do, it will be able to complete the campaign, thinking and perception of this man-machine communication function and function Well, this current development or relative is in a smart part of the concept and meaning But the real significance of the integrity of this intelligent robot did not actually exist, but as we continued the development of science and technology, the concept of intelligent increasingly rich, it grows ever wider connotations.Now, I would like to briefly outline some of the industrial robot situation. So far, the industrial robot is the most mature and widely used category of a robot, now the world's total sales of 1.1 million Taiwan, which is the 1999 statistics, however, 1.1 million in Taiwan have been using the equipment is 75 million, this volume is not small. Overall, the Japanese industrial robots in this one, is the first of the robots to become the Kingdom, the United States have developed rapidly. Newly installed in several areas of Taiwan, which already exceeds Japan, China has only just begun to enter the stage of industrialization, has developed a variety of industrial robot prototype and small batch has been used in production.Spot welding robot is the auto production line, improve production efficiency and raise the quality of welding car, reduce the labor intensity of a robot. It is characterized by two pairs of robots for spot welding of steel plate, bearing a great need for the welding tongs, general in dozens of kilograms or more, then its speed in meters per second a 5-2 meter of such high-speed movement. So it is generally five to six degrees of freedom, load 30 to 120 kilograms, the great space, probably expected that the work of a spherical space, a high velocity, the concept of freedom, that is to say, Movement is relatively independent of the number of components, the equivalent of our body, waist is a rotary degree of freedom We have to be able to hold his arm, Arm can be bent, then this three degrees of freedom, Meanwhile there is a wristposture adjustment to the use of the three autonomy, the general robot has six degrees of freedom. We will be able to space the three locations, three postures, the robot fully achieved, and of course we have less than six degrees of freedom. Have more than six degrees of freedom robot, in different occasions the need to configure.The second category of service robots, with the development of industrialization, especially in the past decade, Robot development in the areas of application are continuously expanding, and now a very important characteristic, as we all know, Robot has gradually shifted from manufacturing to non-manufacturing and service industries, we are talking about the car manufacturer belonging to the manufacturing industry, However, the services sector including cleaning, refueling, rescue, rescue, relief, etc. These belong to the non-manufacturing industries and service industries, so here is compared with the industrial robot, it is a very important difference. It is primarily a mobile platform, it can move to sports, there are some arms operate, also installed some as a force sensor and visual sensors, ultrasonic ranging sensors, etc. It’s surrounding environment for the conduct of identification, to determine its campaign to complete some work, this is service robot’s one of the basic characteristics.For example, domestic robot is mainly embodied in the example of some of the carpets and flooring it to the regular cleaning and vacuuming. The robot it is very meaningful, it has sensors, it can furniture and people can identify, It automatically according to a law put to the ground under the road all cleaned up. This is also the home of some robot performance.The medical robots, nearly five years of relatively rapid development of new application areas. If people in the course of an operation, doctors surgery, is a fatigue, and the other manually operated accuracy is limited. Some universities in Germany, which, facing the spine, lumbar disc disease, the identification, can automatically use the robot-aided positioning, operation and surgery Like the United States have been more than 1,000 cases of human eyeball robot surgery, the robot, also including remote-controlled approach, the right of such gastrointestinal surgery, we see on the television inside. a manipulator, about the thickness fingers such a manipulator, inserted through the abdominal viscera, people on the screen operating the machines hand, it also used the method of laser lesion laser treatment, this is the case, peoplewould not have a very big damage to the human body.In reality, this right as a human liberation is a very good robots, medical robots it is very complex, while it is fully automated to complete all the work, there are difficulties, and generally are people to participate. This is America, the development of such a surgery Lin Bai an example, through the screen, through a remote control operator to control another manipulator, through the realization of the right abdominal surgery A few years ago our country the exhibition, the United States has been successful in achieving the right to the heart valve surgery and bypass surgery. This robot has in the area, caused a great sensation, but also, AESOP's surgical robot, In fact, it through some equipment to some of the lesions inspections, through a manipulator can be achieved on some parts of the operation Also including remotely operated manipulator, and many doctors are able to participate in the robot under surgery Robot doctor to include doctors with pliers, tweezers or a knife to replace the nurses, while lighting automatically to the doctor's movements linked, the doctor hands off, lighting went off, This is very good, a doctor's assistant.Robot is mankind's right-hand man; friendly coexistence can be a reliable friend. In future, we will see and there will be a robot space inside, as a mutual aide and friend. Robots will create the jobs issue. We believe that there would not be a "robot appointment of workers being laid off" situation, because people with the development of society, In fact the people from the heavy physical and dangerous environment liberated, so that people have a better position to work, to create a better spiritual wealth and cultural wealth.译文资料:机器人首先我介绍一下机器人产生的背景,机器人技术的发展,它应该说是一个科学技术发展共同的一个综合性的结果,同时,为社会经济发展产生了一个重大影响的一门科学技术,它的发展归功于在第二次世界大战中各国加强了经济的投入,就加强了本国的经济的发展。

这种一体化提供了机器人保持行走甚至跌倒时的problems and advance the study of vision-based behaviors, we have adopted a new approach through building remote-brained robots. The body and the brain are connected by wireless links by using wireless cameras and remote-controlled actuators.As a robot body does not need computers on-board,it becomes easier to build a lightweight body with many DOFS in actuation.In this research, we developed a two-armed bipedal robot using the remote-brained robot environment and made it to perform balancing based on vision and getting up through cooperating arms and legs. The system and experimental results are described below.2 The Remote-Brained SystemThe remote-brained robot does not bring its own brain within the body. It leaves the brain in the mother environment and communicates with it by radio links. This allows us to build a robot with a free body and a heavy brain. The connection link between the body and the brain defines the interface between software and hardware. Bodies are designed to suit each research project and task. This enables us advance in performing research with a variety of real robot systems[10].A major advantage of remote-brained robots is that the robot can have a large and heavy brain based on super parallel computers. Although hardware technology for vision has advanced and produced powerful compact vision systems, the size of the hardware is still large. Wireless connection between the camera and the vision processor has been a research tool. The remote-brained approach allows us to progress in the study of a variety of experimental issues in vision-based robotics.Another advantage of remote-brained approach is that the robot bodies can be lightweight. This opens up the possibility of working with legged mobile robots. AsFigure 4 shows some of the classes in the programming environent for remote-brained robot written in Euslisp. The hierachy in the classes provides us with rich facilities for extending development of various robots.4 Vision-Based BalancingThe robot can stand up on two legs. As it can change the gravity center of its body by controling the ankle angles, it can perform static bipedal walks. During static walking the robot has to control its body balance if the ground is not flat and stable.In order to perform vision-based balancing it is re-quired to have high speed vision system to keep ob-serving moving schene. We have developed a tracking vision board using a correlation chip[l3]. The vision board consists of a transputer augmented with a special LSI chip(MEP[14] : Motion Estimation Processor) which performs local image block matching.The inputs to the processor MEP are an image as a reference block and an image for a search window.The size of the reference blsearch window depends on the size of the reference block is usually up to 32 by 32 pixels so that it can include 16 * 16 possible matches. The processor calculates 256 values of SAD (sum of absolute difference) between the reference block and 256 blocks in the search window and also finds the best matching block, that is, the one which has the minimum SAD value.Clock is up to 16 by 16 pixels.The size of the search window depends on the size of the reference block is usually up to 32 by 32 pixels so that it can include 16 * 16 possible matches. The processor calculates 256 values of SAD (sum of absolute difference) between the reference block and 256 blocks in the search window and also finds the best matching block, that is, the one which has the minimum SAD value.Block matching is very powerful when the target moves only in translation. However, the ordinary block matching method cannot track the target when it rotates. In order to overcome this difficulty, we developed a new method which follows up the candidate templates to real rotation of the target. The rotated template method first generates all the rotated target images in advance, and several adequate candidates of the reference template are selected and matched is tracking the scene in the front view. It remembers the vertical orientation of an object as the reference for visual tracking and generates several rotated images of the reference image. If the vision tracks the reference object using the rotated images, it can measures the body rotation. In order to keep the body balance, the robot feedback controls its body rotation to control the center of the body gravity. The rotational visual tracker[l5] can track the image at video rate.5 Biped WalkingIf a bipedal robot can control the center of gravity freely, it can perform biped walk. As the robot shown in Figure 2 has the degrees to left and right directions at the ankle position, it can perform bipedal walking in static way.The motion sequence of one cycle in biped walking consists of eight phases as shown in Figure 6. One step consists of four phases; move-gravity-center-on-foot,lift-leg, move-forward-leg, place-leg. As the body is described in solid model, the robot can generate a body configuration for move-gravity-center-on-foot according to the parameter of the hight of the gravity center. After this movement, the robot can lift the other leg and move it forward. In lifting leg, the robot has to control the configuration in order to keep the center of gravity above the supporting foot. As the stability in balance depends on the hight of the gravity center, the robot selects suitable angles of the knees.Figure 7 shows a sequence of experiments of the robot in biped walking6 Rolling Over and Standing UpFigure 8 shows the sequence of rolling over, sitting and standing up. This motion requires coordination between arms and legs.As the robot foot consists of a battery, the robot can make use of the weight of the battery for the roll-over motion. When the robot throws up the left leg and moves the left arm back and the right arm forward, it can get rotary moment around the body. If the body starts turning, the right leg moves back and the left foot returns its position to lie on the face. This rollover motion changes the body orientation from face up to face down. It canbe verified by the orientation sensor.After getting face down orientation, the robot moves the arms down to sit on two feet. This motion causes slip movement between hands and the ground. If the length of the arm is not enough to carry the center of gravity of the body onto feet, this sitting motion requires dynamic pushing motion by arms. The standing motion is controlled in order to keep the balance.7 Integration through Building Sensor-Based Transition NetIn order to integrate the basic actions described above, we adopted a method to describe a sensor-based transition network in which transition is considered according to sensor status. Figure 9 shows a state transition diagram of the robot which integrates basic actions: biped walking, rolling over, sitting, and standing up. This integration provides the robot with capability of keeping walking even when it falls down.The ordinary biped walk is composed by taking two states, Left-leg Fore and Right-leg Fore, successively.The poses in ‘Lie on the Back’ and ‘Lie on the Face’are as same as one in ‘Stand’. That is, the shape ofthe robot body is same but the orientation is different.The robot can detect whether the robot lies on the back or the face using the orientation sensor. When the robot detects falls down, it changes the state to ‘Lie on the Back’ or ‘Lie on the Front’ by moving to the neutral pose. If the robot gets up from ‘Lie on the Back’, the motion sequence is planned to exe cute Roll-over, Sit and Stand-up motions. If the state is ‘Lie on the Face’, it does not execute Roll-over but moves arms up to perform the sitting motion.8 Concluding RemarksThis paper has presented a two-armed bipedal robot which can perform statically biped walk, rolling over and standing up motions. The key to build such behaviors is the remote-brained approach. As the experiments have shown, wireless technologies permit robot bodies free movement. It also seems to change the way we conceptualize robotics. In our laboratory it has enabled the development of a new research environment, better suited to robotics and real-world AI.The robot presented here is a legged robot. As legged locomotion requires dynamic visual feedback control, its vision-based behaviors can prove the effectiveness of the vision system and the remote-brained system. Our vision system is based on high speed block matching function implemented with motion estimation LSI. The vision system provides the mechanical bodies with dynamic and adaptive capabilities in interaction with human. The mechanical dog has shown adaptive behaviors based on distance。

It should be said it is a common scientific and technological development of a comprehensive results, for the socio-economic development of a significant impact on a science and technology. It attributed the development of all countries in the Second World War to strengthen the economic input on strengthening the country's economic development. But they also demand the development of the productive forces the inevitable result of human development itself is the inevitable result then with the development of humanity, people constantly discuss the natural process, in understanding and reconstructing the natural process, people need to be able to liberate a slave. So this is the slave people to be able to replace the complex and engaged in heavy manual labor, People do not realize right up to the world's understanding and transformation of this technology as well as people in the development process of an objective need.Robots are three stages of development, in other words, we are accustomed to regarding robots are divided into three categories. is a first-generation robots, also known as teach-type robot, it is through a computer, to control over one of a mechanical degrees of freedom Through teaching and information stored procedures, working hours to read out information, and then issued a directive so the robot can repeat according to the people at that time said the results show this kind of movement again, For example, the car spot welding robots, only to put this spot welding process, after teaching, and it is always a repeat of a work It has the external environment is no perception that the force manipulation of the size of the work piece there does not exist, welding 0S It does not know, then this fact from the first generation robot, it will exist this shortcoming, it in the 20th century, the late 1970s, people started to study the second-generation robot, called Robot with the feeling that This feeling with the robot is similar in function of a certain feeling, for instance, force and touch, slipping, visual, hearing and who is analogous to that with all kinds of feelings, say in a robot grasping objects, In fact, it can be the size of feeling out, it can through visual, to be able to feel and identify its shape, size, color Grasping an egg, it adopted a acumen, aware of its power and the size of the slide.Third-generation robots, we were a robotics ideal pursued by the most advanced stage, called intelligent robots, So long as tell it what to do, not how to tell it to do, it will be able to complete the campaign, thinking and perception of this man-machine communication function and function Well, this current development or relative is in a smart part of the concept and meaning But the real significance of the integrity of this intelligent robot did not actually exist, but as we continued the development of science and technology, the concept of intelligent increasingly rich, it grows ever wider connotations.Now I have a brief account of China's robot development of the basic profiles. As our country there are many other factors that problem. Our country in robotics research of the 20th century the late 1970s. At that time, we organized at the national, a Japanese industrial automation products exhibition. In this meeting, there are two products, is a CNC machine tools, an industrial robot, this time, our country's many scholars see such a direction, has begun to make a robot research But this time, are basically confined to the theory of phase .Then the real robot research, in 7500 August 5, 1995, 15 nearly 20 years of development, The most rapid development, in 1986 we established a national plan of 863 high-technology development plan, As robot technology will be an important theme of the development of The state has invested nearly Jiganyi funds begun to make a robot, We made the robot in the field quickly and rapid development.At present, units like the CAS ShenYng Institute of Automation, the original machinery, automation of the Ministry, as of Harbin Industrial University, Beijing University of Aeronautics and Astronautics, Qinghua University, Chinese Academy of Sciences, also includes automation of some units, and so on have done a very important study, also made a lot of achievements Meanwhile, in recent years, we end up in college, a lot of flats in robot research, Many graduate students and doctoral candidates are engaged in robotics research, we are more representative national study Industrial robots, underwater robots, space robots, robots in the nuclear industry are on the international level should be taking the lead .On the whole of our country Compared with developed countries, there is still a big gap, primarily manifested in the We in the robot industry, at present there is no fixed maturity product, but in theseunderwater, space, the nuclear industry, a number of special robots, we have made a lot of achievements characteristics.Now, I would like to briefly outline some of the industrial robot situation. So far, the industrial robot is the most mature and widely used category of a robot, now the world's total sales of 1.1 million Taiwan, which is the 1999 statistics, however, 1.1 million in Taiwan have been using the equipment is 75 million, this volume is not small. Overall, the Japanese industrial robots in this one, is the first of the robots to become the Kingdom, the United States have developed rapidly. Newly installed in several areas of Taiwan, which already exceeds Japan, China has only just begun to enter the stage of industrialization, has developed a variety of industrial robot prototype and small batch has been used in production.Spot welding robot is the auto production line, improve production efficiency and raise the quality of welding car, reduce the labor intensity of a robot. It is characterized by two pairs of robots for spot welding of steel plate, bearing a great need for the welding tongs, general in dozens of kilograms or more, then its speed in meters per second a 5-2 meter of such high-speed movement. So it is generally five to six degrees of freedom, load 30 to 120 kilograms, the great space, probably expected that the work of a spherical space, a high velocity, the concept of freedom, that is to say, Movement is relatively independent of the number of components, the equivalent of our body, waist is a rotary degree of freedom We have to be able to hold his arm, Arm can be bent, then this three degrees of freedom, Meanwhile there is a wrist posture adjustment to the use of the three autonomy, the general robot has six degrees of freedom. We will be able to space the three locations, three postures, the robot fully achieved, and of course we have less than six degrees of freedom. Have more than six degrees of freedom robot, in different occasions the need to configure.The second category of service robots, with the development of industrialization, especially in the past decade, Robot development in the areas of application are continuously expanding, and now a very important characteristic, as we all know, Robot has gradually shifted from manufacturing to non-manufacturing and service industries, we are talking about the car manufacturer belonging to the manufacturing industry, However, the services sector including cleaning, refueling, rescue, rescue,relief, etc. These belong to the non-manufacturing industries and service industries, so here is compared with the industrial robot, it is a very important difference. It is primarily a mobile platform, it can move to sports, there are some arms operate, also installed some as a force sensor and visual sensors, ultrasonic ranging sensors, etc. It’s surrounding environment for the conduct of identification, to determine its campaign t o complete some work, this is service robot’s one of the basic characteristics.For example, domestic robot is mainly embodied in the example of some of the carpets and flooring it to the regular cleaning and vacuuming. The robot it is very meaningful, it has sensors, it can furniture and people can identify, It automatically according to a law put to the ground under the road all cleaned up. This is also the home of some robot performance.The medical robots, nearly five years of relatively rapid development of new application areas. If people in the course of an operation, doctors surgery, is a fatigue, and the other manually operated accuracy is limited. Some universities in Germany, which, facing the spine, lumbar disc disease, the identification, can automatically use the robot-aided positioning, operation and surgery Like the United States have been more than 1,000 cases of human eyeball robot surgery, the robot, also including remote-controlled approach, the right of such gastrointestinal surgery, we see on the television inside. a manipulator, about the thickness fingers such a manipulator, inserted through the abdominal viscera, people on the screen operating the machines hand, it also used the method of laser lesion laser treatment, this is the case, people would not have a very big damage to the human body.In reality, this right as a human liberation is a very good robots, medical robots it is very complex, while it is fully automated to complete all the work, there are difficulties, and generally are people to participate. This is America, the development of such a surgery Lin Bai an example, through the screen, through a remote control operator to control another manipulator, through the realization of the right abdominal surgery A few years ago our country the exhibition, the United States has been successful in achieving the right to the heart valve surgery and bypass surgery. This robot has in the area, caused a great sensation, but also, AESOP's surgical robot, In fact, it through some equipment to some of the lesions inspections, through amanipulator can be achieved on some parts of the operation Also including remotely operated manipulator, and many doctors are able to participate in the robot under surgery Robot doctor to include doctors with pliers, tweezers or a knife to replace the nurses, while lighting automatically to the doctor's movements linked, the doctor hands off, lighting went off, This is very good, a doctor's assistant.We regard this country excel, it should be said that the United States, Russia and France, in our nation, also to the international forefront, which is the CAS ShenYang Institute of Automation of developing successful, 6,000 meters underwater without cable autonomous underwater robot, the robot to 6,000 meters underwater, can be conducted without cable operations. His is 2000, has been obtained in our country one of the top ten scientific and technological achievements. This indicates that our country in this underwater robot, have reached the advanced international level, 863 in the current plan, the development of 7,000 meters underwater in a manned submersible to the ocean further development and operation, This is a great vote of financial and material resources.In this space robotics research has also been a lot of development. In Europe, including 16 in the United States space program, and the future of this space capsule such a scheme, One thing is for space robots, its main significance lies in the development of the universe and the benefit of mankind and the creation of new human homes, Its main function is to scientific investigation, as production and space scientific experiments, satellites and space vehicles maintenance and repair, and the construction of the space assembly. These applications, indeed necessary, for example, scientific investigation, as if to mock the ground some physical and chemical experiments do not necessarily have people sitting in the edge of space, because the space crew survival in the day the cost is nearly one million dollars. But also very dangerous, in fact, some action is very simple, through the ground, via satellite control robot, and some regularly scheduled completion of the action is actually very simple. Include the capsule as control experiments, some switches, buttons, simple flange repair maintenance, Robot can be used to be performed by robots because of a solar battery, then the robot will be able to survive, we will be able to work, We have just passed the last robot development on the application of the different areas ofapplication, and have seen the robots in industry, medical, underwater, space, mining, construction, service, entertainment and military aspects of the application .Also really see that the application is driven by the development of key technologies, a lack of demand, the robot can not, It is because people in understanding the natural transformation of the natural process, the needs of a wide range of robots, So this will promote the development of key technologies, the robot itself for the development of From another aspect, as key technology solutions, as well as the needs of the application, on the promotion of the robot itself a theme for the development of intelligent, and from teaching reappearance development of the current local perception of the second-generation robot, the ultimate goal, continuously with other disciplines and the development of advanced technology, the robot has become rich, eventually achieve such an intelligent robot mainstream.Robot is mankind's right-hand man; friendly coexistence can be a reliable friend. In future, we will see and there will be a robot space inside, as a mutual aide and friend. Robots will create the jobs issue. We believe that there would not be a "robot appointment of workers being laid off" situation, because people with the development of society, In fact the people from the heavy physical and dangerous environment liberated, so that people have a better position to work, to create a better spiritual wealth and cultural wealth.译文:机器人首先我介绍一下机器人产生的背景,机器人技术的发展,它应该说是一个科学技术发展共同的一个综合性的结果,同时,为社会经济发展产生了一个重大影响的一门科学技术,它的发展归功于在第二次世界大战中各国加强了经济的投入,就加强了本国的经济的发展。

RobotsA robot is an automatically controlled, reprogrammable, multipurpose, mani pulating machine with several reprogrammable axes, which may be either fixed in place or mobile for use in industrial automation applications.The key words are reprogrammable and multipurpose because most single-purpose machines do not meet these two requirements.The term”reprogrammabl e” implies two things:The robot operates according to a written program can b e rewritten to accomdate a variety of manufacturing tasks. The term “multipurp ose” means that the robot can perform many different functions, depending on the program and tooling currently in use.Over the past two decades,the robot has been introduced into industry to perform many monotonous and often unsafe operations. Because robots can per form certain basic tasks more quickly and accurately than humans, they are bei ng increasingly used in various manufacturing industries.Structures of RobotsThe typical structure of industrial robots consists of 4 major components: the manipulator, the end effector, the power supply and control syterm.The manipulator is a mechanical unite that provides motions similar to those of a human arm. It often has a shoulder joint,an elbow and a wrist. It can rotate or slide, strech out and withdraw in every possible direction with certain flexibility.The basic mechanical configurations of the robot manipulator are categorized as Cartesian, cylindrical, spherical and articulated.A robot with a Cartesian geometry can move its gripper to any position within the cube or rectangle defined as its working volum.Cylindrical coordinate robots can move the gripper within a volum that is described by a cylinder. The cylindrical coordinate robot is positioned in the work area by two linear movements in the X and Y directions and one angular rotation about the Z axis.Spherical arm geometry robots have an irregular work envelop. This type of robot has two main variants,vertically articulated and horizontally articulated.The end effector attaches itself to the end of the robot wrist, also called end-of-arm tooling.It is the device intended for performing the designed operations as a human hand can.End effectors are generally custom-made to meet special handling requirements. Mechanical grippers are the most commonly used and are equipped with two or more fingers.The selection of an appropriate end effector for a special application depends on such factors as the payload, enviyonment,reliability,and cost.The power supply is the actuator for moving the robot arm, controlling the joints and operating the end effector. The basic type of power sources include electrical,pneumatic, and hydraulic. Each source of energy and each type of motor has its own characteristics, advantages and limitations. An ac-powered motor or dc-powered motor may be used depending on the system design and applications. These motors convert electrical energy into mechanical energy to power the robot.Most new robots use electrical power supply. Pneumatic actuators have been used for high speed. Nonservo robots and are often used for powering tooling such as grippers. Hydraulic actuators have been used for heavier lift systems, typically where accuracy was not also requied.The contro system is the communications and information-processing system that gives commands for the movements of the robot. It is the brain of the robot; it sends signals to the power source to move the robot arm to a specific position and to the end effector.It is also the nerves of the robot; it is reprogrammable to send out sequences of instructions for all movements and actions to be taken by the robot.A open-loop controller is the simplest for of the control system, which controls the robot only by foolowing the predetermined step-by-step instructions.This system dose not have a self-correcting capability.A close-loop control system use feedback sensors to produce signals that reflct the current states of the controed objects. By comparing those feedback signals with the values set by the programmer, the close-loop controller can conduct the robot to move to the precise position and assume the desired attitude, and the end effector can perform with very high accuracy as the close-loop control system can minimize the discrepancy between the controlled object and the predetermined references.Classification of RobotIndustrial robots vary widely in size,shape, number of axes,degrees of freedom, and design configuration. Each factor influence the dimensions of the robot’s working envelop or the volume of space within which it can move and perform its designated task. A broader classification of robots can been described as below.Fixed-and Variable-Sequence Robots. The fixed-sequence robot (also called a pick-and place robot) is programmed for a specific sequence of operations. Its movements are form point to point, and the cycle is repeated continuously.The variable-sequence robot can be programmed for a specific sequence of operations but can be programmed to perform another sequence of operation.Playback Robot. An operator leads or walks the playback robot and its end effector through the desired path. The robot memorizes and records the path and sequence of motions and can repeat them continually without any further action or guidance by the operator.Numerically Controlled Robot. The numerically controlled robot is programmed and operated much like a numerically controlled machine. The robot is servocontrolled by digital data, and its sequence of movements can be changed with relative ease.Intelligent Robot. The intelligent robot is capable of performing some of the functions and tasks carried out by huanbeings.It is equipped with a variety of sensors with visual and tactile capabilities.Robot ApplicationsThe robot is a very special type of productin tool; as a result, the applications in which robots are used are quite broad. These applications can be grouped into three categories: material processing, material handling and assembly.In material processing, robots use tools to process the raw material. For example, the robot tools could include a drill and the robot would be able to perfor drilling operaytions on raw material.Material handling consists of the loading, unloading, and transferring of workpieces in manufacturing facilities. These operations can be performed relatively and repeatedly with robots, thereby improving quality and scrap losses.Assembly is another large application area for using robotics. An automatic assembly system can incorporate automatic testing, robot automation and mechanical handling for reducing labor costs, increasing output and eliminating manual handling concers.机器人机器人是一种自动控制的、可重复编程的、多功能的、由几个可重复编程的坐标系来操纵机器的装置,它可以被固定在某地,还可以是移动的以在工业自动化工厂中使用。

英文原文The Abyss Transit System- James Cameron commissions the making of robots for a return to theTitanicBy Gary StixAt the beginning of the movie that made Leonardo DiCaprio a megastar, a camera-toting unmanned robot ventured into a cavernous hole in the wreck that sits on the bottom of the Atlantic, 12,640 feet from the surface. The 500-pound vehicle, christened Snoop Dog, could move only about 30 feet along a lower deck, hampered by its bulky two-inch-diameter tether hitched to a submarine that waited above. The amount of thrust needed to move its chunky frame stirred up a thick cloud. “The vehicle very quickly silted out the entire place and made imaging impossible,” director James Cameron recalls.But the eerie vista revealed by Snoop Dog on that 1995 expedition made Cameron hunger for more. He vowed to return one day with technology that could negotiate anyplace within the Titanic's interior.In the past six months two documentaries—one for IMAX movie theaters called Ghosts of the Abyss, the other, Expedition: Bismarck, for the DiscoveryChannel—demonstrated the fruits of a three-year effort that Cameron financed with $1.8 million of his own money to make this vision materialize. The payoff was two 70-pound robots, named after Blues Brothers Jake and Elwood, that had the full run of two of the world's most famous wrecks, the Titanic and the Bismarck, which they visited on separate expeditions.The person who took Jake and Elwood from dream to robot is Mike Cameron, James's brother, an aerospace engineer who once designed missiles and who also possesses a diverse background as a helicopter pilot, stunt photographer and stuntman. (Remember the corpse in the movie The Abyss, from whose mouth a crab emerges?) Giving the remotely operated vehicles freedom of movement required that they be much smaller than Snoop Dog and that the tether's width be tapered dramatically so as not to catch on vertical ship beams.Mike Cameron took inspiration from the wire-guided torpedoes used by the military that can travel for many miles. His team created vehicles operable to more than 20,000 feet (enough to reach as much as 85 percent of the ocean floor). The dimensions of the front of the robot are 16 inches high by 17 inches across, small enough to fit in a B deck window of the Titanic. The bots have an internal battery so that they do not need to be powered through a tether. Instead the tether—fifty-thousandths of an inch in diameter—contains optical fibers that relaycontrol signals from a manned submersible vehicle hovering outside and that also send video images in the other direction. The tether pays out from the robot, a design that prevents it from snagging on objects in the wreck.James Cameron thought the project would be a straightforward engineering task, not much harder than designing a new camera system. “This turned out to be a whole different order of magnitude,” he says. “There was no commercial off-the-shelf hardware that wo uld work in the vehicles. Everything had to be built from scratch.” If the team had known this early on, he added, “we wouldn't have bothered.” Water pressure on the cable that carried the optical fibers could create microscopic bends in the data pipe, completely cutting off the control signals from the submersibles. Dark Matter in Valencia, Calif. (Mike Cameron's company), had to devise a fluid-filled sheath around the fiber to displace the minuscule air pockets in the cable that could lead to the microbending.To save weight, the frame—similar to a monocoque body of a race car—was made up of small glass hollow spheres contained in an epoxy matrix. The thruster contained a large-diameter, slowly rotating blade with nozzles that diffused the propulsive flow, minimizing the churning that would otherwise disturb the caked silt.A high-resolution video camera, along with an infrared camera for navigation, was placed in the front of the craft along with three light-emitting-diode arrays for fill lighting and two quartz halogen lamps for spotlighting.The winter of 2001 marked a critical juncture. It was six months before dives to the Titanic could be safely attempted, and James had to determine whether to proceed or wait another year. “Mike was really, really negative on the idea, but I decided to go for it,” the director says. He felt he couldn't afford to wait longer and thought that a fixed deadline would focus the engineering staff at Dark Matter. Forhis part, Mike was contending with an unending series of design challenges. “It was such an overwhelming set of problems that I had very little confidence that certain parts would be solvable in the time we had,” Mike says.A few weeks before the dives commenced in the summer of 2001, the robots' lithium sulfur dioxode-based batteries caught fire while being tested in a pressure tank, destroying what was to have been a third robot. Mike wanted to delay the dives, but James found a supplier of another type of lithium battery and pressed ahead.At the dive site, Jake and Elwood took starring roles with their 2,000-foot tethers, exploring for the first time in about 90 years remote parts of the ships, including the engine room, the firemen's mess hall and the cabins of first-class passengers—even focusing in on a bowler hat, a brass headboard and an intact, upright glass decanter. The images lack the resolution and novel quality of the high-definition, three-dimensional IMAX images, the other major technological innovation of Ghostsof the Abyss. Jake and Elwood's discoveries, however, draw the viewers' interest because of what they convey of the Titanic's mystique. “You actually feel like you're out there in the wreck,” Mike says. He remembers his brother piloting the robots with the helicopter stick that had been installed in the Russian submersible from which the robots were launched. “Jim ended up being a cowboy pilot,” Mike says. “He was far more aggressive with the system than I was.”One scene in Ghosts of the Abyss reveals the tension that sometimes erupted between the brothers. James contemplates moving one of the robots through a cabin window that is still partially occluded by a shard of glass that could damage the vehicle or cut the data tether. When James declares that he is going to take Jake in, moviegoers can hear Mike pleading with his brother not to do it, ultimately relenting once the bot has negotiated the opening.The decision to install a new type of battery at the last minute came to haunt the expedition; Elwood's lithium-polymer battery ignited while in the bowels of the ship. James manipulated the remaining robot into the Titanic to perform a rescue operation by hooking a cord to the grill of the dead bot and towing it out. At the surface—on the deck of the Russian scientific vessel the Keldysh, from which the two submarines carrying Jake and Elwood to the Titanic were launched—Mike rebuilt Elwood with a backup battery. During the next dive, the robot caught fire again while it was still mounted on the submarine, endangering the crew. Finally, Mike worked for an 18-hour stretch to adapt a lead-acid gel battery used for devices onboard the mother ship into a power source for Elwood, enabling the expedition to continue.The bots, now fitted with a new, nonflammable battery that Mike designed, may find service beyond motion pictures. The U.S. Navy has funded Dark Matter to help it assess the technology for underwater recovery operations of ships or aircraft. The bots also have potential for scientific exploration of deep-sea trenches. After traveling to the Titanic and the Bismarck, the team went on to probe mid-Atlantic hydrothermal vents, discovering mollusks in a place where scientists had never encountered them before. As adventure aficionados, the brothers speculate that a descendant of Jake and Elwood might even be toted on a mission to Europa, one of Jupiter's moons, to investigate the waters that are suspected to exist below its icy shell. The Cameron siblings, who tinkered with home-built rafts and rockets as children in Ontario near Niagara Falls, hope to be around long enough to witness their robotic twins go from the bottom of the ocean to the depths of space.中文译文穿越深渊的机器--新型的机器人可在数百公尺深的水底残骸间自由穿梭游览作者╱斯蒂克斯( Gary Stix )曾一举捧红超级巨星李奥纳多狄卡皮欧的电影「铁达尼号」中,片头是一台无人驾驶的遥控装置,携带着摄影机深入大西洋,在3852公尺深的铁达尼号残骸里冒险的画面。

中英文资料外文翻译文献(文档含英文原文和中文翻译)一种实用的办法--带拖车移动机器人的反馈控制摘要本文提出了一种有效的方法来控制带拖车移动机器人。

轨迹跟踪和路径跟踪这两个问题已经得到解决。

接下来的问题是解决迭代轨迹跟踪。

并且把扰动考虑到路径跟踪内。

移动机器人Hilare的实验结果说明了我们方法的有效性。

1引言过去的8年,人们对非完整系统的运动控制做了大量的工作。

布洛基[2]提出了关于这种系统的一项具有挑战性的任务,配置的稳定性,证明它不能由一个简单的连续状态反馈。

作为替代办法随时间变化的反馈[10,4,11,13,14,15,18]或间断反馈[3]也随之被提出。

从[5]移动机器人的运动控制的一项调查可以看到。

另一方面,非完整系统的轨迹跟踪不符合布洛基的条件,从而使其这一个任务更为轻松。

许多著作也已经给出了移动机器人的特殊情况的这一问题[6,7,8,12,16]。

所有这些控制律都是工作在相同的假设下:系统的演变是完全已知和没有扰动使得系统偏离其轨迹。

很少有文章在处理移动机器人的控制时考虑到扰动的运动学方程。

但是[1]提出了一种有关稳定汽车的配置,有效的矢量控制扰动领域,并且建立在迭代轨迹跟踪的基础上。

存在的障碍使得达到规定路径的任务变得更加困难,因此在执行任务的任何动作之前都需要有一个路径规划。

在本文中,我们在迭代轨迹跟踪的基础上提出了一个健全的方案,使得带拖车的机器人按照规定路径行走。

该轨迹计算由规划的议案所描述[17],从而避免已经提交了输入的障碍物。

在下面,我们将不会给出任何有关规划的发展,我们提及这个参考的细节。

而且,我们认为,在某一特定轨迹的执行屈服于扰动。

我们选择的这些扰动模型是非常简单,非常一般。

它存在一些共同点[1]。

本文安排如下:第2节介绍我们的实验系统Hilare及其拖车:两个连接系统将被视为(图1)。

Intelligent plant trimming robotOverview of Intelligent Lawn Mowers:With the development of economy, urban construction in various countries is gradually deepening, and the greening degree of urban areas is also improving. A large number of public green Spaces such as park lawn, football field lawn and GOLF course lawn need to be maintained.Among all kinds of lawn maintenance operations, turf mowing is the most onerous, which is not only boring, but also highly repetitive, and usually requires a large amount of manpower and material resources.In order to reduce the labor intensity and cost of lawn maintenance, China has put forward the strategy of transforming and upgrading lawn machinery industry with modern electronic technology and intelligent control technology in recent years, hoping to replace the traditional lawn mower with intelligent intelligent lawn mower robot in the near future.Intelligent lawn mowing robot belongs to the field of civil outdoor mobile robot. From the perspective of system science, it is a comprehensive robot system that integrates environment perception, path dynamic planning and decision-making, behavior control and execution, and other functions.This paper introduces a standard intelligent lawnmower robot system, which usually consists of four parts: perception system, control system, moving mechanism and lawnmower structure.The sensing system monitors the external environment variables, the moving mechanism and the operating parameters of the mower in real time, and sends the results to the control system.The control system compares the obtained data with its own database, and sends out correction instructions to the moving mechanism and the lawn mower according to the path planning, so as to obtain stable pared with thetraditional lawn mowing machine, the intelligent lawn mowing robot has the characteristics of environmental protection, low manpower consumption and high security.Research overview of intelligent lawn mower robot:Abroad in the field of intelligent mowing robot research and development, many of the companies do a lot of work, has been part of the product listed as Rboomower FrinediyMachines design company, is currently one of the most successful intelligent mowing robot products, adopt the three-wheel car agency, two rear wheel independent drive, front wheel as the universal wheel, can run on the basis of a certain strategy repeated back to within the range set in advance, after when it encounters obstacles by ultrasonic sensors and then simple detour, but it does not guarantee in addition to the obstacles of area.There is no concept of a global map and no concept of whether mowing an entire lawn has been completed.There are other similar products, each with its own features, such as Uzeehetti's Oear, a deluxe version of the A811Brigio, which even has a rain sensor that automatically hides when it rains.Auotmower, from Sweden's Eleetr-Ofux, is powered by batteries and can also be powered by solar power.Bigmow from Berlbooties, Belgium, has excellent path algorithm, large blade coverage area, high coverage.The research on lawnmowing robot carried out by foreign scientific research institutions mainly focuses on the direction of intelligent control technology, navigation technology and path planning of lawnmowing robot, while the system design for lawnmowing robot is relatively few.The United States patent US4919224 uses a battery power supply, can start at a predetermined time, with obstacles to avoid theft and automatic charging and other functions, using three wires for navigation.When encountered rain, wetlands, power shortage and other outside thesituation, back to the garage, the patent uses ultrasonic to detect obstacles, with shock detector and password to prevent illegal users to operate the machine;U.S. patent US5204814 adopted to optimize the navigation technology, comprehensive utilization of storage paths and environmental information, without magnetic current of metal wires and buried metal conductor is three ways to guide the movement of the mowing robot, the patent also choose to do the internal combustion engine power, cooperate with the generator and battery pack is used, adopts the distributed control mode.The research on lawn-mowing robot started late in China, and there are few research units involved in this field, but some achievements have been made.The mechanical school of nanjing university of science and technology designed MORO mobile mowing robot, and successfully developed MORO.I, MORO.II and other models of mowing robot.Nanjing university of science and technology to the general design of the mowing robot, path planning and obstacle avoidance, positioning system, control system and so on, a more comprehensive discussion was carried out theoretically and puts forward the general scheme of a cheap and practical, also according to the robot dynamics equation is deduced the formula for calculation of driving moment for the choice of motor, control system hardware circuit provides the calculation basis of main components parameters laid the foundation for further in-depth study mowing robot.The main navigation equipment of MORO mobile lawn mower robot is drive wheel encoder and magnetic heading sensor, which can automatically generate beacon-free boundary to realize the whole area covering walking.The volume of the robot is about 80X51X40 C m³, the weight is about 50kg, the blade speed is up to 5000r/min, suitable for large lawn mowing work.In addition, Nanjing University of Science and Technology also introduced the cutting-edge technology in the field of robotics to the lawn mower robot, such as the Internet-based robot control technology and the key technology of solar lawn mower.Different from other wheeled mowing robots, Jiangsu University developed a crawler mowing robot, which has the function of GPS positioning and navigation. It can operate efficiently and at a high speed, and is suitable for large areas of grassland.This robot is composed of two parts, one part is the AS.RF robot produced by Guangmaoda company, the other part is the self-designed lawn mower platform.In addition, Jiangsu University also provides a reasonable cutting height for different lawns, which provides an important basis for the research of lawn-mowing robot.The necessity of research on intelligent lawn mower robot:With the development of economy, lawn industry has become a new industry in wn has basically been applied in urban landscaping and sports ground construction.The lawn industry began a period of slow, steady, and gathering strength.That prompted the lawn industry began to experience a transformation process from labor-intensive to knowledge-intensive, lawn mowing maintenance, in particular, urgently needs a more efficient, lower consumption and energy consumption and personnel's lawn machinery and equipment, but automatically lawn mower of foreign equipment expensive prices and monopoly technology restricted the our country to promote progress in automation and intelligence of lawn machinery, so must depend on own strength research with independent intellectual property rights intelligent mowing robot.In today's rapid development of science and technology, people's living level gradually improve, some applications in industrial science and technology is gradually out of the factory, the study of intelligent mowing robot provides a new subject for the development of service robots, also is a kind of practical application service robots to attempt and exploration, and, more importantly, the development of the intelligent mowing robot can offer beneficial reference for the process of industrialization of humanoid robot.In addition, the study of intelligent mowing robot has certain academic value. Intelligent mowing robot belongs tooutdoor mobile robot, and it will work in the open unstructured space when mowing grass. How to realize the movement of robot in the unstructured space is an important topic of robot research today.Based on the characteristics of mowing work, intelligent mowing robot is also needed to completely cover the entire working interval in a relatively ideal way. The reflected region full path planning problem is also a research hotspot of path planning.In the manufacturing process of intelligent green plant pruning robot, if the technological process management of each link is not reasonable and scientific, it will cause the safe operation problem of the robot.The use of the robot intelligent system can effectively monitor the safety factor of the robot operation in an all-round way, find the work fault, facilitate the equipment management and technical personnel can check and repair in time, and quickly eliminate the hidden danger of safety.In particular, the use of the lawn mower has become an important guarantee for the effective working safety of mechanical energy and the premise for the safe production of enterprises.Finally, the automatic path planning function of the intelligent green plant pruning robot can effectively improve the work efficiency, gradually improve the performance of the robot, so as to continuously improve the requirements of the target equipment, and then meet the actual requirements.This is also the robot into production and quality assurance, through the use of robot intelligent system scientific and reasonable realization, constantly summarize the domestic robot short board, research methods and technology, and the actual situation of its production combined, to achieve the modernization of the manufacturing of intelligent robots, and effectively into the actual use.Of course, the actual use of robots causes noise and emission pollution.So these two things have to be taken into account in the process of making robots.Save energy and realize the sustainable use of energy;Reduce noise and do not affect residents' lives;Discharge pollution-free, protect the environment.To sum up, the research on intelligent lawnmower robot has important commercial value, positive social value and certain academic value, which can reflect the development level of automation technology and robotics in China. Therefore, it is very necessary to carry out related research work on intelligent lawnmower robot.Selection of driving scheme of intelligent mower robot:Lawn mower robot belongs to outdoor mobile robot. There are various driving schemes for this type of robot for reference.According to the working characteristics of outdoor mobile robot, the driving scheme of autonomous mobile robot platform is discussed in detail.There are many kinds of outdoor mobile robots, such as wheeled, tracked and foot.Wheel and crawler driving modes are suitable for relatively smooth road surfaces, while foot driving modes are suitable for special and relatively harsh environments. Some mobile robots mix these driving modes in order to adapt to various road surfaces.The mowing robot generally works on the lawn with good conditions. Combined with other work requirements, the mowing robot mostly chooses the wheel-driven mode.Selection of sensor parts:In order to work autonomously in unknown or time-varying environments, mobile robots should have the ability to feel the operating environment and plan their own movements.Mobile robot obstacle avoidance is the key problem of how to use sensors to perceive the environment in the process of movement and fixing the robots in the work area, any kind of sensor has its own advantages and disadvantages, choose need to carefully consider various factors, sensor system in the operation of the mobile robot, the machine is needed for mobile robot into nearby the existence of information as well as the obstacles and distance q robots, robot navigation related position information.The intelligent lawnmowing robot works in the open outdoor space. When it performs the lawnmowing task, it needs to obtain the information of the peripheral obstacles and the position of the robot itself. The sensors involved include the distance sensor and the position sensor.In addition, because the intelligent mowing robot is equipped with a high-speed rotating blade, the relevant sensors should be selected to ensure its safety.The commonly used distance sensors of mobile robots include ultrasonic sensors, infrared sensors and laser ranging sensors.Among them, the cost of laser ranging sensor is relatively high, and it is not suitable for civil service robot system, so it will not be considered in this paper.Ultrasonic sensor is a sensor developed by using the reflection characteristics of ultrasonic wave, the effective detection range is 30cm-2m;The infrared sensor is a proximity sensor, and the infrared wave length emitted is about within the range of several hundred nanometers. It belongs to short-wavelength electromagnetic, and the effective detection range is usually less than 30cm.The intelligent lawn-mowing robot needs to detect the obstacles in the LCM-1.5m outside the vehicle when it is running, so ultrasonic sensors or infrared sensors cannot be used alone.Therefore, this paper chooses the combination of ultrasonic sensor and infrared sensor to realize the obstacle distance detection of the intelligent lawn-mowing robot.In addition, the intelligent lawn-mowing robot works in the outdoor environment where the temperature changes greatly, and the measurement results of the ultrasonic sensor will be subject to temperature changes and deviations from the actual value. Therefore, in order to obtain accurate and stable data collection, a separate temperature sensor is required to collect the ambient temperature to correct the errors generated.When the intelligent mowing robot runs, the internal mowing blade will rotate at a high speed, which will cause potential harm to people and animals. Special attention should be paid to safety issues, so the intelligent mowing robot in this paper also uses contact sensors and human bodythermal release sensors.The contact sensor belongs to the tactile sensor, which is set around the robot in the form of array. When the robot collides with the object accidentally, it is used to generate the interrupt signal.Human thermal release sensor is a sensor that detects the infrared radiation emitted by human or animal body and outputs electrical signals. When the intelligent mowing robot is working, if someone or animal enters the set safe range, it will issue the corresponding alarm signal.Design of control system of intelligent mowing robot:The control system of intelligent lawnmowing robot is an important part of intelligent lawnmowing robot, which needs to carry out a series of decision control to the robot, and it even decides the advantages and disadvantages of the robot's performance to a certain extent.Therefore, the chip selection, control strategy and communication mode of the intelligent lawnmowing robot should be discussed in detail, and the best plan should be decided.Advantages of robotic lawn mowers:Robot lawn mower can work independently, whether it is a more traditional internal combustion engine as power system of the lawn mower is relatively new in lawn mower battery as a power system, both because of their simple structure and the principle of science and technology content is low, low degree of automation, must be control by people, compared with the original is to improve the efficiency of a certain human work, but not completely the liberation of human.The robot mower is automatically controlled by the intelligent system and can finish the mowing operation independently, which greatly saves human resources.The main advantages of robotic lawn mowers can be analyzed from the following points:Robot mowers have little pollution. The traditional mowers with internalcombustion engines as the power system need to consume oil. Due to the characteristics of the equipment, the energy conversion rate is low, resulting in a lot of unnecessary energy waste.In addition, the traditional lawn mower produces a lot of noise when working, and this sound pollution will cause great harm to the surrounding environment and have a certain negative impact on the mental health of workers.The robot lawnmower uses clean energy and does not require direct contact between humans and machines, which is less harmful to the environment and people.Robot mower has high efficiency, which is divided into two aspects: working efficiency and energy utilization efficiency.The traditional lawn mower with internal combustion engine as the power system is heavy, inflexible and easily subject to terrain restrictions, resulting in low working efficiency.The relatively new mowers with battery as power system are limited in power due to the influence of battery volume, so they may need to charge for many times in one operation, which will actually reduce the working efficiency.The robot mower is equipped with terrain detector and sensor, which can automatically analyze the terrain and adjust the best working route to maintain high efficiency.And the robot mower has built-in automatic return program, when the energy shortage will automatically return to the base to charge, without manual intervention.Robot lawnmower has high safety. Traditional lawnmowers are high-power machines. If a fault occurs during work, it is easy to cause harm to workers.The new lawnmower completely liberates man from such danger as well.A lawn mower robot usually works on a definite surface, which requires the robot to be able to move independently to each site in the area.Therefore, it is necessary to set up the working route or the way of traveling in the working process for the robot, such as the spiral contraction path or the return-type movement mode.In addition, after the work in one area is finished, the navigation system is also needed toguide the robot to move to another area to continue working.Sometimes, due to some unexpected or special reasons, it is necessary to intervene in the work of the lawn mower robot, so that it can change its working range or stop working.This requires the robot to be able to receive the signals sent by human beings and make corresponding responses to them. Therefore, it is necessary to place a remote control module on the robot to facilitate human control.Because of the precision of the sensor, the requirements of the robot mower for the working environment will be increased correspondingly, otherwise it may cause damage to the sensor.However, the working environment of lawn mowers is complex, and some unstable factors in the environment may have adverse effects on the accuracy of information collection.The collected information is large and vulnerable to interference.This will easily cause some uncertain errors in the process of information collection or processing, which will affect the normal work of the lawn-mowing robot.The development prospect of robot lawn mower:With the characteristics of its automated work, lawn-mowing robot can liberate people from boring labor, save a lot of human resources for the production and life of modern society, meet the trend and need of social development, and its advantages are numerous, reflecting the application prospect of enough, so its market must be very extensive.However, due to technical limitations, it is immature in many aspects.Therefore, there will be a "low price is low, high price is excellent" situation, which is a very unfavorable factor for its competition in the market.In the current market, the relatively poor performance of the traditional lawn mower with its low price to occupy the dominant position, but its low efficiency, high energy consumption, unsafe shortcomings are also criticized by users.However, as the process of urban development accelerates, the demand for greening increases, so thesocial demand for lawnmower will gradually increase. However, the disadvantage of serious pollution of traditional lawnmower is contrary to the original intention of greening construction. Therefore, it can be judged that the lawnmower with small pollution and high efficiency will gradually be favored.So the robot lawn mower is currently facing the main problem is how to improve the performance in technology, and how to reduce the cost in production to lower the price, so as to achieve greater competitiveness in the market.For example, different mowing robots can be made according to different nature of work to meet higher precision requirements or to avoid unnecessary waste of some functions. In this way, the price of robotic mowers can be reduced to a certain extent.Robot lawn mower is a very promising market project, it can bring great convenience to people's life.But at the same time, due to its advanced technology, it is also a difficult project to achieve breakthrough progress.Therefore, in this aspect of the research, we need to make more efforts to improve its shortcomings, to ensure that it can really be put into production application.智能割草机器人的概述:随着经济的发展,各国城市建设逐渐深化,城区的绿化程度也随之提高,大量的公园草坪、足球场草坪、GOLF 球场草坪等公共绿地均需要进行维护。

外文资料robotThe industrial robot is a tool that is used in the manufacturing environment to increase productivity. It can be used to do routine and tedious assembly line jobs,or it can perform jobs that might be hazardous to the human worker . For example ,one of the first industrial robot was used to replace the nuclear fuel rods in nuclear power plants. A human doing this job might be exposed to harmful amounts of radiation. The industrial robot can also operate on the assembly line,putting together small components,such as placing electronic components on a printed circuit board. Thus,the human worker can be relieved of the routine operation of this tedious task. Robots can also be programmed to defuse bombs,to serve the handicapped,and to perform functions in numerous applications in our society.The robot can be thought of as a machine that will move an end-of-tool ,sensor ,and/or gripper to a preprogrammed location. When the robot arrives at this location,it will perform some sort of task .This task could be welding,sealing,machine loading ,machine unloading,or a host of assembly jobs. Generally,this work can be accomplished without the involvement of a human being,except for programming and for turning the system on and off.The basic terminology of robotic systems is introduced in the following:1. A robot is a reprogrammable ,multifunctional manipulator designed to move parts,material,tool,or special devices through variable programmed motions for the performance of a variety of different task. This basic definition leads to other definitions,presented in the following paragraphs,that give acomplete picture of a robotic system.2. Preprogrammed locations are paths that the robot must follow to accomplish work,At some of these locations,the robot will stop and perform some operation ,such as assembly of parts,spray painting ,or welding .These preprogrammed locations are stored in the robot’s memory and are recalled later for continuousoperation.Furthermore,these preprogrammed locations,as well as other program data,can be changed later as the work requirements change.Thus,with regard to this programming feature,an industrial robot is very much like a computer ,where data can be stoned and later recalled and edited.3. The manipulator is the arm of the robot .It allows the robot to bend,reach,and twist.This movement is provided by the manipulator’s axes,also called the degrees of freedom of the robot .A robot can have from 3 to 16 axes.The term degrees of freedom will always relate to the number of axes found on a robot.4. The tooling and frippers are not part the robotic system itself;rather,they are attachments that fit on the end of the robot’s arm. These attachments connected to the end of the robot’s arm allow the robot to lift parts,spot-weld ,paint,arc-weld,drill,deburr,and do a variety of tasks,depending on what is required of the robot.5. The robotic system can control the work cell of the operating robot.The work cell of the robot is the total environment in which the robot must perform itstask.Included within this cell may be the controller ,the robot manipulator ,a work table ,safety features,or a conveyor.All the equipment that is required in order for the robot to do its job is included in the work cell .In addition,signals from outside devices can communicate with the robot to tell the robot when it should parts,pick up parts,or unload parts to a conveyor.The robotic system has three basic components: the manipulator,the controller,and the power source.A.ManipulatorThe manipulator ,which does the physical work of the robotic system,consists of two sections:the mechanical section and the attached appendage.The manipulator also has a base to which the appendages are attached.Fig.1 illustrates the connectionof the base and the appendage of a robot.图1.Basic components of a robot’s manipulatorThe base of the manipulator is usually fixed to the floor of the work area. Sometimes,though,the base may be movable. In this case,the base is attached to either a rail or a track,allowing the manipulator to be moved from one location to anther.As mentioned previously ,the appendage extends from the base of the robot. The appendage is the arm of the robot. It can be either a straight ,movable arm or a jointed arm. The jointed arm is also known as an articulated arm.The appendages of the robot manipulator give the manipulator its various axes of motion. These axes are attached to a fixed base ,which,in turn,is secured to a mounting. This mounting ensures that the manipulator will in one location.At the end of the arm ,a wrist(see Fig 2)is connected. The wrist is made up of additional axes and a wrist flange. The wrist flange allows the robot user to connect different tooling to the wrist for different jobs.图2.Elements of a work cell from the topThe manipulator’s axes allow it to perform work within a certain area. The area is called the work cell of the robot ,and its size corresponds to the size of the manipulator.(Fid2)illustrates the work cell of a typical assembly ro bot.As the robot’s physical size increases,the size of the work cell must also increase.The movement of the manipulator is controlled by actuator,or drive systems.The actuator,or drive systems,allows the various axes to move within the work cell. The drive system can use electric,hydraulic,or pneumatic power.The energy developed by the drive system is converted to mechanical power by various mechanical power systems.The drive systems are coupled through mechanical linkages.These linkages,in turn,drive the different axes of the robot.The mechanical linkages may be composed of chain,gear,and ball screws.B.ControllerThe controller in the robotic system is the heart of the operation .The controller stores preprogrammed information for later recall,controls peripheral devices,and communicates with computers within the plant for constant updates in production.The controller is used to control the robot manipulator’s movements as well as to control peripheral components within the work cell. The user can program the movements of the manipulator into the controller through the use of a hard-held teach pendant.This information is stored in the memory of the controller for later recall.The controller stores all program data for the robotic system.It can store several differentprograms,and any of these programs can be edited.The controller is also required to communicate with peripheral equipment within the work cell. For example,the controller has an input line that identifies when a machining operation is completed.When the machine cycle is completed,the input line turn on telling the controller to position the manipulator so that it can pick up the finished part.Then ,a new part is picked up by the manipulator and placed into the machine.Next,the controller signals the machine to start operation.The controller can be made from mechanically operated drums that step through a sequence of events.This type of controller operates with a very simple robotic system.The controllers found on the majority of robotic systems are more complex devices and represent state-of-the-art eletronoics.That is,they are microprocessor-operated.these microprocessors are either 8-bit,16-bit,or 32-bit processors.this power allows the controller to be very flexible in its operation.The controller can send electric signals over communication lines that allow it to talk with the various axes of the manipulator. This two-way communication between the robot manipulator and the controller maintains a constant update of the end the operation of the system.The controller also controls any tooling placed on the end of the robot’s wrist.The controller also has the job of communicating with the different plant computers. The communication link establishes the robot as part a computer-assisted manufacturing (CAM)system.As the basic definition stated,the robot is a reprogrammable,multifunctional manipulator.Therefore,the controller must contain some of memory stage. The microprocessor-based systems operates in conjunction with solid-state devices.These memory devices may be magnetic bubbles,random-access memory,floppy disks,or magnetic tape.Each memory storage device stores program information fir or for editing.C.power supplyThe power supply is the unit that supplies power to the controller and the manipulator. The type of power are delivered to the robotic system. One type of power is the AC power for operation of the controller. The other type of power isused for driving the various axes of the manipulator. For example,if the robot manipulator is controlled by hydraulic or pneumatic drives,control signals are sent to these devices causing motion of the robot.For each robotic system,power is required to operate the manipulator .This power can be developed from either a hydraulic power source,a pneumatic power source,or an electric power source.There power sources are part of the total components of the robotic work cell.中文翻译机器人工业机器人是在生产环境中用以提高生产效率的工具,它能做常规乏味的装配线工作,或能做那些对于工人来说是危险的工作,例如,第一代工业机器人是用来在核电站中更换核燃料棒,如果人去做这项工作,将会遭受有害放射线的辐射。

机器人外文翻译(中英文翻译)机器人外文翻译(中英文翻译)With the rapid development of technology, the use of robots has become increasingly prevalent in various industries. Robots are now commonly employed to perform tasks that are dangerous, repetitive, or require a high level of precision. However, in order for robots to effectively communicate with humans and fulfill their intended functions, accurate translation between different languages is crucial. In this article, we will explore the importance of machine translation in enabling robots to perform translation tasks, as well as discuss current advancements and challenges in this field.1. IntroductionMachine translation refers to the use of computer algorithms to automatically translate text or speech from one language to another. The ultimate goal of machine translation is to produce translations that are as accurate and natural as those generated by human translators. In the context of robots, machine translation plays a vital role in allowing them to understand and respond to human commands, as well as facilitating communication between robots of different origins.2. Advancements in Machine TranslationThe field of machine translation has experienced significant advancements in recent years, thanks to breakthroughs in artificial intelligence and deep learning. These advancements have led to the development of neural machine translation (NMT) systems, which have greatly improved translation quality. NMT models operate by analyzinglarge amounts of bilingual data, allowing them to learn the syntactic and semantic structures of different languages. As a result, NMT systems are capable of providing more accurate translations compared to traditional rule-based or statistical machine translation approaches.3. Challenges in Machine Translation for RobotsAlthough the advancements in machine translation have greatly improved translation quality, there are still challenges that need to be addressed when applying machine translation to robots. One prominent challenge is the variability of language use, including slang, idioms, and cultural references. These nuances can pose difficulties for machine translation systems, as they often require a deep understanding of the context and cultural background. Researchers are currently working on developing techniques to enhance the ability of machine translation systems to handle such linguistic variations.Another challenge is the real-time requirement of translation in a robotic setting. Robots often need to process and translate information on the fly, and any delay in translation can affect the overall performance and efficiency of the robot. Optimizing translation speed without sacrificing translation quality is an ongoing challenge for researchers in the field.4. Applications of Robot TranslationThe ability for robots to translate languages opens up a wide range of applications in various industries. One application is in the field of customer service, where robots can assist customers in multiple languages, providing support and information. Another application is in healthcare settings, where robots can act as interpreters between healthcare professionals and patientswho may speak different languages. Moreover, in international business and diplomacy, robots equipped with translation capabilities can bridge language barriers and facilitate effective communication between parties.5. ConclusionIn conclusion, machine translation plays a crucial role in enabling robots to effectively communicate with humans and fulfill their intended functions. The advancements in neural machine translation have greatly improved translation quality, but challenges such as language variability and real-time translation requirements still exist. With continuous research and innovation, the future of machine translation for robots holds great potential in various industries, revolutionizing the way we communicate and interact with technology.。

外文原文Introduction to Industrial RobotsIndustrial robets became a reality in the early 1960’s when Joseph Engelberger and George Devol teamed up to form a robotics company they called “Unimation”.Engelberger and Devol were not the first to dream of machines that could perform the unskilled, repetitive jobs in manufacturing. The first use of the word “robots” was by the Czechoslovakian philosopher and playwright Karel Capek in his play R.U.R.(Rossum’s Universal Robot). The word “robot” in Czech means “worker” or “slave.” The play was written in 1922.In Capek’s play , Rossum and his son discover the chemical formula for artificial protoplasm. Protoplasm forms the very basis of life.With their compound,Rossum and his son set out to make a robot.Rossum and his son spend 20 years forming the protoplasm into a robot. After 20 years the Rossums look at what they have created and say, “It’s absurd to spend twenty years making a man if we can’t make him quicker than nature, you might as w ell shut up shop.”The young Rossum goes back to work eliminating organs he considers unnecessary for the ideal worker. The young Rossum says, “A man is something that feels happy , plays piano ,likes going for a walk, and in fact wants to do a whole lot of things that are unnecessary … but a working machine must not play piano, must not feel happy, must not do a whole lot of other things. Everything that doesn’t contribute directly to the progress of work should be eliminated.”A half century later, engi neers began building Rossum’s robot, not out of artificial protoplasm, but of silicon, hydraulics, pneumatics, and electric motors. Robots that were dreamed of by Capek in 1922, that work but do not feel, that perform unhuman or subhuman, jobs in manufacturing plants, are available and are in operation around the world.The modern robot lacks feeling and emotions just as Rossum’s son thought it should. It can only respond to simple “yes/no” questions. The moderrn robot is normally bolted to the floor. It has one arm and one hand. It is deaf, blind, and dumb. In spite of all of these handicaps, the modern robot performs its assigned task hour after hour without boredom or complaint.A robot is not simply another automated machine. Automation began during the industrial revolution with machines that performed jobs that formerly had been done by human workers. Such a machine, however , can do only the specific job for which it was designed, whereas a robot can perform a variety of jobs.A robot must have an arm. The arm must be able to duplicate the movements of a human worker in loading and unloading other automated machines, spraying paint, welding, and performing hundreds of other jobs that cannot be easily done with conventional automated machines.DEFINITION OF A ROBOTThe Robot Industries Association(RIA) has published a definition for robots in an attempt to clarify which machines are simply automated machines and which machines are truly robots. The RIA definition is as follows:“A robot is a reprogrammabl e multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks.”This definition, which is more extensive than the one in the RIA glossary at the end of this book, is an excellent definition of a robot. We will look at this definition, one phrase at a time, so as to understand which machines are in fact robots and which machines are little more than specialized automation.First, a robot is a “reprogrammable multifunctional manipulator.” In this phrase RIA tells us that a robot can be taught (“reprogrammed”) to do more than one job by changing the informaion stored in its memory. A robot can be reprogrammed to load and unload machines, weld, and do ma ny other jobs (“multifunctional”). A robot is a“manipulator”. A manipulator is an arm( or hand ) that can pick up or move things. At this point we know that a robot is an arm that can be taught to do different jobs.The definition goes on to say that a ro bot is “designed to move material, parts, tools, or specialized devices.” Material includes wood,steel, plastic, cardboard… anything that is used in the manufacture of a product.A robot can also handle parts that have been manufactured. For example, a robot can load a piece of steel into an automatic lathe and unload a finished part out of the lathe.In addition to handling material and parts, a robot can be fitted with tools such as grinders, buffers, screwdrivers, and welding torches to perform useful work.Robots can also be fitted with specialized instruments or devices to do special jobs in a manufacturing plant. Robots can be fitted with television cameras for inspection of parts or products. They can be fitted with lasers to accurately mearure the size of parts being manufactured.The RIA definition closes with the phrase,”…through variable programmed motions for the performance of a variety of tasks.” This phrase emphasizes the fact that a robot can do many different jobs in a manufacturing plant. The variety of jobs that a robot can do is limited only by the creativity of the application engineer.JOBS FOR ROBOTSJobs performed by robots can be divided into two major categories:hazardous jobs and repetitive jobs.Hazardous JobsMany applications of robots are in jobs that are hazardous to humans. Such jobs may be considered hazardous because of toxic fumes, the weight of the material being handled, the temperature of the material being handled, the danger of working near rotating or press machinery, or environments containing high levels of radiation. Repetitive JobsIn addition to taking over hazardous jobs, robots are well suited to doingextremely repetitive jobs that must be done in manufacturing plants.many jobs in manufacturing plants require a person to act more like a machine than like a human. The job may be to pick a piece up from here and place it there. The same job is done hundreds of times each day. The job requires little or no judgment and little or no skill. This is not said as a criticism of the person who does the job , but is intended simply to point out that many of these jobs exist in industry and must be done to complete the manufacture of products. A robot can be placed at such a work station and can perform the job admirably without complaining or experiencing the fatigue and boredom normally associated with such a job.Although robots eliminate some jobs in industry, they normally eliminate jobs that humans should never have been asked to do. Machines should perform as machines doing machine jobs, and humans should be placed in jobs that require the use of their ability,creativity, and special skills.POTENTIAL FOR INCREASED PRODUCTIVITYIn addition to removing people from jobs they should not have been placed in, robots offer companies the opportunity of achieving increased productivity. When robots are placed in repetitive jobs they continue to operate at their programmed pace without fatigue. Robots do not take either scheduled or unscheduled breaks from the job. The increase in productivity can result in at least 25% more good parts being produced in an eight-hour shift. This increase in productivity increases the company's profits, which can be reinvested in additional plants and equipment. This increase in productivity results in more jobs in other departments in the plant. With more parts being produced, additional people are needed to deliver the raw materials to the plant, to complete the assembly of the finished products, to sell the finished products, and to deliver the products to their destinations.ROBOT SPEEDAlthough robots increase productivity in a manufacturing plant, they are notexceptionally fast. At present, robots normally operate at or near the speed of a human operator. Every major move of a robot normally takes approximately one second. For a robot to pick up a piece of steel from a conveyor and load it into a lathe may require ten different moves taking as much as ten seconds. A human operator can do the same job in the same amount of time . The increase in productivity is a result of the consistency of operation. As the human operator repeats the same job over and over during the workday, he or she begins to slow down. The robot continues to operate at its programmed speed and therefore completes more parts during the workday.Custom-built automated machines can be built to do the same jobs that robots do. An automated machine can do the same loading operation in less than half the time required by a robot or a human operator. The problem with designing a special machine is that such a machine can perform only the specific job for which it was built. If any change is made in the job, the machine must be completely rebuilt, or the machine must be scrapped and a new machine designed and built. A robot, on the other hand, could be reprogrammed and could start doing the new job the same day.Custom-built automated machines still have their place in industry. If a company knows that a job will not change for many years, the faster custom-built machine is still a good choice.Other jobs in factories cannot be done easily with custom-built machinery. For these applications a robot may be a good choice. An example of such an application is spray painting. One company made cabinets for the electronics industry. They made cabinets of many different sizes, all of which needed painting. It was determined that it was not economical for the company to build special spray painting machines for each of the different sizes of enclosures that were being built. Until robots were developed, the company had no choice but to spray the various enclosures by hand.Spray painting is a hazardous job , because the fumes from many paints are both toxic and explosive. A robot is now doing the job of spraying paint on the enclosures.A robot has been “taught” to spray all the different sizes of enclosures that the company builds. In addition, the robot can operate in the toxic environment of the spray booth without any concern for the long-term effect the fumes might have on aperson working in the booth.FLEXIBLE AUTOMATIONRobots have another advantage: they can be taught to do different jobs in the manufacturing plant. If a robot was originally purchased to load and unload a punch press and the job is no longer needed due to a change in product design, the robot can be moved to another job in the plant. For example, the robot could be moved to the end of the assembly operation and be used to unload the finished enclosures from a conveyor and load them onto a pallet for shipment.ACCURACY AND REPEATABILITYOne very important characteristic of any robot is the accuracy with which it can perform its task. When the robot is programmed to perform a specific task, it is led to specific points and programmed to remember the locations of those points. After programming has been completed, the robot is switched to “run” and the program is executed. Unfortunately, the robot will not go to the exact location of any programmed point. For example, the robot may miss the exact point by 0.025 in. If 0.025 in. is the greatest error by which the robot misses any point- during the first execution of the program, the robot is said to have an accuracy of 0.025 in.In addition to accuracy , we are also concerned with the robot’s repeatability. The repeatability of a robot is a measure of how closely it returns to its programmed points every time the program is executed. Say , for example, that the robot misses a programmed point by 0.025 in. the first time the program is executed and that, during the next execution of the program, the robot misses the point it reached during the previous cycle by 0.010 in. Although the robot is a total of 0.035 in. from the original programmed point, its accuracy is 0.025 in. and its repeatability is 0.010 in.THE MAJOR PARTS OF A ROBOTThe major parts of a robot are the manipulator, the power supply, and the controller.The manipulator is used to pick up material, parts, or special tools used in manufacturing. The power supply suppplies the power to move the manipulator. The controller controls the power supply so that the manipulator can be taught to perform its task.外文翻译工业机器人的介绍20世纪60年代当约瑟夫和乔治合作创立了名为Unimation的机器公司,工业机器人便成为了一个事实。

外文翻译外文资料:RobotsFirst, I explain the background robots, robot technology development. It should be said it is a common scientific and technological development of a comprehensive results, for the socio-economic development of a significant impact on a science and technology. It attributed the development of all countries in the Second World War to strengthen the economic input on strengthening the country's economic development. But they also demand the development of the productive forces the inevitable result of human development itself is the inevitable result then with the development of humanity, people constantly discuss the natural process, in understanding and reconstructing the natural process, people need to be able to liberate a slave. So this is the slave people to be able to replace the complex and engaged in heavy manual labor, People do not realize right up to the world's understanding and transformation of this technology as well as people in the development process of an objective need.Robots are three stages of development, in other words, we are accustomed to regarding robots are divided into three categories. is a first-generation robots, also known as teach-type robot, it is through a computer, to control over one of a mechanical degrees of freedom Through teaching and information stored procedures, working hours to read out information, and then issued a directive so the robot can repeat according to the people at that time said the results show this kind of movement again, For example, the car spot welding robots, only to put this spot welding process, after teaching, and it is always a repeat of a work It has the external environment is no perception that the force manipulation of the size of the work piece there does not exist, welding 0S It does not know, then this fact from the first generation robot, it will exist this shortcoming, it in the 20th century, the late 1970s, people started to study the second-generation robot, called Robot with the feeling that This feeling with the robot is similar in function of a certain feeling, for instance, force and touch, slipping, visual, hearing and who is analogous to that withall kinds of feelings, say in a robot grasping objects, In fact, it can be the size of feeling out, it can through visual, to be able to feel and identify its shape, size, color Grasping an egg, it adopted a acumen, aware of its power and the size of the slide. Third-generation robots, we were a robotics ideal pursued by the most advanced stage, called intelligent robots, So long as tell it what to do, not how to tell it to do, it will be able to complete the campaign, thinking and perception of this man-machine communication function and function Well, this current development or relative is in a smart part of the concept and meaning But the real significance of the integrity of this intelligent robot did not actually exist, but as we continued the development of science and technology, the concept of intelligent increasingly rich, it grows ever wider connotations.Now I have a brief account of China's robot development of the basic profiles. As our country there are many other factors that problem. Our country in robotics research of the 20th century the late 1970s. At that time, we organized at the national, a Japanese industrial automation products exhibition. In this meeting, there are two products, is a CNC machine tools, an industrial robot, this time, our country's many scholars see such a direction, has begun to make a robot research But this time, are basically confined to the theory of phase .Then the real robot research, in 7500 August 5, 1995, 15 nearly 20 years of development, The most rapid development, in 1986 we established a national plan of 863 high-technology development plan, As robot technology will be an important theme of the development of The state has invested nearly Jiganyi funds begun to make a robot, We made the robot in the field quickly and rapid development.At present, units like the CAS ShenYng Institute of Automation, the original machinery, automation of the Ministry, as of Harbin Industrial University, Beijing University of Aeronautics and Astronautics, Qinghua University, Chinese Academy of Sciences, also includes automation of some units, and so on have done a very important study, also made a lot of achievements Meanwhile, in recent years, we end up in college, a lot of flats in robot research, Many graduate students and doctoral candidates are engaged in robotics research, we are more representative national study Industrial robots, underwater robots, space robots, robots in the nuclear industry areon the international level should be taking the lead .On the whole of our country Compared with developed countries, there is still a big gap, primarily manifested in the We in the robot industry, at present there is no fixed maturity product, but in these underwater, space, the nuclear industry, a number of special robots, we have made a lot of achievements characteristics.Now, I would like to briefly outline some of the industrial robot situation. So far, the industrial robot is the most mature and widely used category of a robot, now the world's total sales of 1.1 million Taiwan, which is the 1999 statistics, however, 1.1 million in Taiwan have been using the equipment is 75 million, this volume is not small. Overall, the Japanese industrial robots in this one, is the first of the robots to become the Kingdom, the United States have developed rapidly. Newly installed in several areas of Taiwan, which already exceeds Japan, China has only just begun to enter the stage of industrialization, has developed a variety of industrial robot prototype and small batch has been used in production.Spot welding robot is the auto production line, improve production efficiency and raise the quality of welding car, reduce the labor intensity of a robot. It is characterized by two pairs of robots for spot welding of steel plate, bearing a great need for the welding tongs, general in dozens of kilograms or more, then its speed in meters per second a 5-2 meter of such high-speed movement. So it is generally five to six degrees of freedom, load 30 to 120 kilograms, the great space, probably expected that the work of a spherical space, a high velocity, the concept of freedom, that is to say, Movement is relatively independent of the number of components, the equivalent of our body, waist is a rotary degree of freedom We have to be able to hold his arm, Arm can be bent, then this three degrees of freedom, Meanwhile there is a wrist posture adjustment to the use of the three autonomy, the general robot has six degrees of freedom. We will be able to space the three locations, three postures, the robot fully achieved, and of course we have less than six degrees of freedom. Have more than six degrees of freedom robot, in different occasions the need to configure.The second category of service robots, with the development of industrialization, especially in the past decade, Robot development in the areas of application are continuously expanding, and now a very important characteristic, as we all know,Robot has gradually shifted from manufacturing to non-manufacturing and service industries, we are talking about the car manufacturer belonging to the manufacturing industry, However, the services sector including cleaning, refueling, rescue, rescue, relief, etc. These belong to the non-manufacturing industries and service industries, so here is compared with the industrial robot, it is a very important difference. It is primarily a mobile platform, it can move to sports, there are some arms operate, also installed some as a force sensor and visual sensors, ultrasonic ranging sensors, etc. It’s surrounding environment for the conduct of identification, to determine its campaign to complete some work, this is service rob ot’s one of the basic characteristics.For example, domestic robot is mainly embodied in the example of some of the carpets and flooring it to the regular cleaning and vacuuming. The robot it is very meaningful, it has sensors, it can furniture and people can identify, It automatically according to a law put to the ground under the road all cleaned up. This is also the home of some robot performance.The medical robots, nearly five years of relatively rapid development of new application areas. If people in the course of an operation, doctors surgery, is a fatigue, and the other manually operated accuracy is limited. Some universities in Germany, which, facing the spine, lumbar disc disease, the identification, can automatically use the robot-aided positioning, operation and surgery Like the United States have been more than 1,000 cases of human eyeball robot surgery, the robot, also including remote-controlled approach, the right of such gastrointestinal surgery, we see on the television inside. a manipulator, about the thickness fingers such a manipulator, inserted through the abdominal viscera, people on the screen operating the machines hand, it also used the method of laser lesion laser treatment, this is the case, people would not have a very big damage to the human body.In reality, this right as a human liberation is a very good robots, medical robots it is very complex, while it is fully automated to complete all the work, there are difficulties, and generally are people to participate. This is America, the development of such a surgery Lin Bai an example, through the screen, through a remote control operator to control another manipulator, through the realization of the right abdominal surgery A few years ago our country the exhibition, the United States has beensuccessful in achieving the right to the heart valve surgery and bypass surgery. This robot has in the area, caused a great sensation, but also, AESOP's surgical robot, In fact, it through some equipment to some of the lesions inspections, through a manipulator can be achieved on some parts of the operation Also including remotely operated manipulator, and many doctors are able to participate in the robot under surgery Robot doctor to include doctors with pliers, tweezers or a knife to replace the nurses, while lighting automatically to the doctor's movements linked, the doctor hands off, lighting went off, This is very good, a doctor's assistant.We regard this country excel, it should be said that the United States, Russia and France, in our nation, also to the international forefront, which is the CAS ShenYang Institute of Automation of developing successful, 6,000 meters underwater without cable autonomous underwater robot, the robot to 6,000 meters underwater, can be conducted without cable operations. His is 2000, has been obtained in our country one of the top ten scientific and technological achievements. This indicates that our country in this underwater robot, have reached the advanced international level, 863 in the current plan, the development of 7,000 meters underwater in a manned submersible to the ocean further development and operation, This is a great vote of financial and material resources.In this space robotics research has also been a lot of development. In Europe, including 16 in the United States space program, and the future of this space capsule such a scheme, One thing is for space robots, its main significance lies in the development of the universe and the benefit of mankind and the creation of new human homes, Its main function is to scientific investigation, as production and space scientific experiments, satellites and space vehicles maintenance and repair, and the construction of the space assembly. These applications, indeed necessary, for example, scientific investigation, as if to mock the ground some physical and chemical experiments do not necessarily have people sitting in the edge of space, because the space crew survival in the day the cost is nearly one million dollars. But also very dangerous, in fact, some action is very simple, through the ground, via satellite control robot, and some regularly scheduled completion of the action is actually very simple. Include the capsule as control experiments, some switches, buttons, simpleflange repair maintenance, Robot can be used to be performed by robots because of a solar battery, then the robot will be able to survive, we will be able to work, We have just passed the last robot development on the application of the different areas of application, and have seen the robots in industry, medical, underwater, space, mining, construction, service, entertainment and military aspects of the application .Also really see that the application is driven by the development of key technologies, a lack of demand, the robot can not, It is because people in understanding the natural transformation of the natural process, the needs of a wide range of robots, So this will promote the development of key technologies, the robot itself for the development of From another aspect, as key technology solutions, as well as the needs of the application, on the promotion of the robot itself a theme for the development of intelligent, and from teaching reappearance development of the current local perception of the second-generation robot, the ultimate goal, continuously with other disciplines and the development of advanced technology, the robot has become rich, eventually achieve such an intelligent robot mainstream.Robot is mankind's right-hand man; friendly coexistence can be a reliable friend. In future, we will see and there will be a robot space inside, as a mutual aide and friend. Robots will create the jobs issue. We believe that there would not be a "robot appointment of workers being laid off" situation, because people with the development of society, In fact the people from the heavy physical and dangerous environment liberated, so that people have a better position to work, to create a better spiritual wealth and cultural wealth.译文资料:机器人首先我介绍一下机器人产生的背景,机器人技术的发展,它应该说是一个科学技术发展共同的一个综合性的结果,同时,为社会经济发展产生了一个重大影响的一门科学技术,它的发展归功于在第二次世界大战中各国加强了经济的投入,就加强了本国的经济的发展。
