附录ManipulatorRobot developed in recent decades as high-tech automated production equipment. Industrial robot is an important branch of industrial robots. It features can be programmed to perform tasks in a variety of expectations, in both structure and performance advantages of their own people and machines, in particular, reflects the people's intelligence and adaptability. The accuracy of robot operations and a variety of environments the ability to complete the work in the field of national economy and there are broad prospects for development. With the development of industrial automation, there has been CNC machining center, it is in reducing labor intensity, while greatly improved labor productivity. However, the upper and lower common in CNC machining processes material, usually still use manual or traditional relay-controlled semi-automatic device. The former time-consuming and labor intensive, inefficient; the latter due to design complexity, require more relays, wiring complexity, vulnerability to body vibration interference, while the existence of poor reliability, fault more maintenance problems and other issues. Programmable LogicController PLC-controlled robot control system for materials up and down movement is simple, circuit design is reasonable, with a strong anti-jamming capability, ensuring the system's reliability, reduced maintenance rate, and improve work efficiency. Robot technology related to mechanics, mechanics, electrical hydraulic technology, automatic control technology, sensor technology and computer technology and other fields of science, is a cross-disciplinary integrated technology.1. an overview of industrial manipulatorRobot is a kind of positioning control can be automated and can be re-programmed to change in multi-functional machine, which has multiple degrees of freedom can be used to carry an object in order to complete the work in different environments. Low wages in China, plastic products industry, although still a labor-intensive, mechanical hand use has become increasingly popular. Electronics and automotive industries that Europe and the United States multinational companies very early in their factories in China, the introduction of automated production. But now the changes are those found in industrial-intensive South China, East China's coastal areas, local plastic processing plants have also emerged in mechanical watches began to become increasingly interested in, because they have to face ahigh turnover rate of workers, as well as for the workers to pay work-related injuries fee challenges.With the rapid development of China's industrial production, especially the reform and opening up after the rapid increase in the degree of automation to achieve the workpiece handling, steering, transmission or operation of brazing, spray gun, wrenches and other tools for processing and assembly operations since, which has more and more attracted our attention.Robot is to imitate the manual part of the action, according to a given program, track and requirements for automatic capture, handling or operation of the automatic mechanical devices.In real life, you will find this a problem. In the machine shop, the processing of parts loading time is not annoying, and labor productivity is not high, the cost of production major, and sometimes man-made incidents will occur, resulting in processing were injured. Think about what could replace it with the processing time of a tour as long as there are a few people, and can operate 24 hours saturated human right? The answer is yes, but the robot can come to replace it.Production of mechanical hand can increase the automation level of production and labor productivity; can reduce laborintensity, ensuring product quality, to achieve safe production; particularly in the high-temperature, high pressure, low temperature, low pressure, dust, explosive, toxic and radioactive gases such as poor environment can replace the normal working people. Here I would like to think of designing a robot to be used in actual production.Why would a robot designed to provide a pneumatic power: pneumatic robot refers to the compressed air as power source-driven robot. With pressure-driven and other energy-driven comparison have the following advantages: 1. Air inexhaustible, used later discharged into the atmosphere, does not require recycling and disposal, do not pollute the environment. (Concept of environmental protection) 2. Air stick is small, the pipeline pressure loss is small (typically less than asphalt gas path pressure drop of one-thousandth), to facilitate long-distance transport. 3. Compressed air of the working pressure is low (usually 4 to 8 kg / per square centimeter), and therefore moving the material components and manufacturing accuracy requirements can be lowered. 4. With the hydraulic transmission, compared to its faster action and reaction, which is one of the advantages pneumatic outstanding. 5. The air cleaner media, it will not degenerate, not easy to plug thepipeline. But there are also places where it fly in the ointment: 1. As the compressibility of air, resulting in poor aerodynamic stability of the work, resulting in the implementing agencies as the precision of the velocity and not easily controlled. 2. As the use of low atmospheric pressure, the output power can not be too large; in order to increase the output power is bound to the structure of the entire pneumatic system size increased.With pneumatic drive and compare with other energy sources drive has the following advantages:Air inexhaustible, used later discharged into the atmosphere, without recycling and disposal, do not pollute the environment. Accidental or a small amount of leakage would not be a serious impact on production.Viscosity of air is small, the pipeline pressure loss also is very small, easy long-distance transport.The lower working pressure of compressed air, pneumatic components and therefore the material and manufacturing accuracy requirements can be lowered. In general, reciprocating thrust in 1 to 2 tons pneumatic economy is better.Compared with the hydraulic transmission, and its faster action and reaction, which is one of the outstanding merits of pneumatic.Clean air medium, it will not degenerate, not easy to plug the pipeline.It can be safely used in flammable, explosive and the dust big occasions. Also easy to realize automatic overload protection. 2. the composition, mechanical handRobot in the form of a variety of forms, some relatively simple, some more complicated, but the basic form is the same as the composition of the, Usually by the implementing agencies, transmission systems, control systems and auxiliary devices composed.2.1 Implementing agenciesManipulator executing agency by the hands, wrists, arms, pillars. Hands are crawling institutions, is used to clamp and release the workpiece, and similar to human fingers, to complete the staffing of similar actions. Wrist and fingers and the arm connecting the components can be up and down, left, and rotary movement. A simple mechanical hand can not wrist. Pillars used to support the arm can also be made mobile as needed.2.2 TransmissionThe actuator to be achieved by the transmission system. Sub-transmission system commonly used manipulator mechanical transmission, hydraulic transmission, pneumatic andelectric power transmission and other drive several forms.2.3 Control SystemManipulator control system's main role is to control the robot according to certain procedures, direction, position, speed of action, a simple mechanical hand is generally not set up a dedicated control system, using only trip switches, relays, control valves and circuits can be achieved dynamic drive system control, so that implementing agencies according to the requirements of action. Action will have to use complex programmable robot controller, the micro-computer control.3 mechanical hand classification and characteristicsRobots are generally divided into three categories: the first is the general machinery does not require manual hand. It is an independent not affiliated with a particular host device. It can be programmed according to the needs of the task to complete the operation of the provisions. It is characterized with ordinary mechanical performance, also has general machinery, memory, intelligence ternary machinery. The second category is the need to manually do it, called the operation of aircraft. It originated in the atom, military industry, first through the operation of machines to complete a particular job, and later developed tooperate using radio signals to carry out detecting machines such as the Moon. Used in industrial manipulator also fall into this category. The third category is dedicated manipulator, the main subsidiary of the automatic machines or automatic lines, to solve the machine up and down the workpiece material and delivery. This mechanical hand in foreign countries known as the "Mechanical Hand", which is the host of services, from the host-driven; exception of a few outside the working procedures are generally fixed, and therefore special.Main features:First, mechanical hand (the upper and lower material robot, assembly robot, handling robot, stacking robot, help robot, vacuum handling machines, vacuum suction crane, labor-saving spreader, pneumatic balancer, etc.).Second, cantilever cranes (cantilever crane, electric chain hoist crane, air balance the hanging, etc.)Third, rail-type transport system (hanging rail, light rail, single girder cranes, double-beam crane)4 industrial machinery, application of hand Manipulator in the mechanization and automation of the production process developed a new type of device. In recentyears, as electronic technology, especially computer extensive use of robot development and production of high-tech fields has become a rapidly developed a new technology, which further promoted the development of robot, allowing robot to better achieved with the combination of mechanization and automation.Although the robot is not as flexible as staff, but it has to the continuous duplication of work and labor, I do not know fatigue, not afraid of danger, the power snatch weight characteristics when compared with manual large, therefore, mechanical hand has been of great importance to many sectors, and increasingly has been applied widely, for example:(1) Machining the workpiece loading and unloading, especially in the automatic lathe, combination machine tool use is more common.(2) In the assembly operations are widely used in the electronics industry, it can be used to assemble printed circuit boards, in the machinery industryIt can be used to assemble parts and components.(3) The working conditions may be poor, monotonous, repetitive easy to sub-fatigue working environment to replace human labor.(4) May be in dangerous situations, such as military goods handling, dangerous goods and hazardous materials removal and so on.(5) Universe and ocean development.(6), military engineering and biomedical research and testing. Help mechanical hands: also known as the balancer, balance suspended, labor-saving spreader, manual Transfer machine is a kind of weightlessness of manual load system, a novel, time-saving technology for material handling operations booster equipment, belonging to kinds of non-standard design of series products. Customer application needs, creating customized cases.Manual operation of a simulation of the automatic machinery, it can be a fixed program draws ﹑handling objects or perform household tools to accomplish certain specific actions. Application of robot can replace the people engaged in monotonous ﹑repetitive or heavy manual labor, the mechanization and automation of production, instead of people in hazardous environments manual operation, improving working conditions and ensure personal safety. The late 20th century, 40, the United States atomic energy experiments, the first use of radioactive material handling robot, human robot ina safe room to manipulate various operations and experimentation. 50 years later, manipulator and gradually extended to industrial production sector, for the temperatures, polluted areas, and loading and unloading to take place the work piece material, but also as an auxiliary device in automatic machine tools, machine tools, automatic production lines and processing center applications, the completion of the upper and lower material, or From the library take place knife knife and so on according to fixed procedures for the replacement operation. Robot body mainly by the hand and sports institutions. Agencies with the use of hands and operation of objects of different occasions, often there are clamping ﹑support and adsorption type of care. Movement organs are generally hydraulic pneumatic electrical device drivers. Manipulator can be achieved independently retractable ﹑rotation and lifting movements, generally 2 to 3 degrees of freedom. Robots are widely used in metallurgical industry, machinery manufacture, light industry and atomic energy sectors.Can mimic some of the staff and arm motor function, a fixed procedure for the capture, handling objects or operating tools, automatic operation device. It can replace human labor in order to achieve the production of heavy mechanization andautomation that can operate in hazardous environments to protect the personal safety, which is widely used in machinery manufacturing, metallurgy, electronics, light industry and nuclear power sectors. Mechanical hand tools or other equipment commonly used for additional devices, such as the automatic machines or automatic production line handling and transmission of the workpiece, the replacement of cutting tools in machining centers, etc. generally do not have a separate control device. Some operating devices require direct manipulation by humans; such as the atomic energy sector performs household hazardous materials used in the master-slave manipulator is also often referred to as mechanical hand.Manipulator mainly by hand and sports institutions. Task of hand is holding the workpiece (or tool) components, according to grasping objects by shape, size, weight, material and operational requirements of a variety of structural forms, such as clamp type, type and adsorption-based care such as holding. Sports organizations, so that the completion of a variety of hand rotation (swing), mobile or compound movements to achieve the required action, to change the location of objects by grasping and posture.Robot is the automated production of a kind used in the process of crawling and moving piece features automatic device, which is mechanized and automated production process developed a new type of device. In recent years, as electronic technology, especially computer extensive use of robot development and production of high-tech fields has become a rapidly developed a new technology, which further promoted the development of robot, allowing robot to better achieved with the combination of mechanization and automation. Robot can replace humans completed the risk of duplication of boring work, to reduce human labor intensity and improve labor productivity. Manipulator has been applied more and more widely, in the machinery industry, it can be used for parts assembly, work piece handling, loading and unloading, particularly in the automation of CNC machine tools, modular machine tools more commonly used. At present, the robot has developed into a FMS flexible manufacturing systems and flexible manufacturing cell in an important component of the FMC. The machine tool equipment and machinery in hand together constitute a flexible manufacturing system or a flexible manufacturing cell, it was adapted to small and medium volume production, you can save a huge amount of the work piececonveyor device, compact, and adaptable. When the work piece changes, flexible production system is very easy to change will help enterprises to continuously update the marketable variety, improve product quality, and better adapt to market competition. At present, China's industrial robot technology and its engineering application level and comparable to foreign countries there is a certain distance, application and industrialization of the size of the low level of robot research and development of a direct impact on raising the level of automation in China, from the economy, technical considerations are very necessary. Therefore, the study of mechanical hand design is very meaningful.机械手机械手是近几十年发展起来的一种高科技自动化生产设备。

附录About Modenr Industrial Manipulayor Robot is a type of mechantronics equipment which synthesizes the last research achievement of engine and precision engine, micro-electronics and computer, automation control and drive, sensor and message dispose and artificial intelligence and so on. With the development of economic and the demand for automation control, robot technology is developed quickly and all types of the robots products are come into being. The practicality use of robot not only solves the problems which are difficult to operate for human being, but also advances the industrial automation program. Modern industrial robots are true marvels of engineering. A robot the size of a person can easily carry a load over one hundred pounds and move it very quickly with a repeatability of 0.006inches. Furthermore these robots can do that 24hours a day for years on end with no failures whatsoever. Though they are reprogrammable, in many applications they are programmed once and then repeat that exact same task for years.At present, the research and development of robot involves several kinds of technology and the robot system configuration is so complex that the cost at large is high which to a certain extent limit the robot abroad use. To development economic practicality and high reliability robot system will be value to robot social application and economy development. With he rapid progress with the control economy and expanding of the modern cities, the let of sewage is increasing quickly; with the development of modern technology and the enhancement of consciousness about environment reserve, more and more people realizedthe importance and urgent of sewage disposal. Active bacteria method is an effective technique for sewage disposal. The abundance requirement for lacunaris plastic makes it is a consequent for plastic producing with automation and high productivity. Therefore, it is very necessary to design a manipulator that can automatically fulfill the plastic holding. With the analysis of the problems in the design of the plasticholding manipulator and synthesizing the robot research and development condition in recent years, a economic scheme is concluded on the basis of the analysis of mechanical configuration, transform system, drive device and control system and guided by the idea of the characteristic and complex of mechanical configuration, electronic, software and hardware. In this article, the mechanical configuration combines the character of direction coordinate which can improve the stability and operation flexibility of the system. The main function of the transmission mechanism is to transmit power to implement department and complete the necessary movement. In this transmission structure, the screw transmission mechanism transmits the rotary motion into linear motion. Worm gear can give vary transmission ratio. Both of the transmission mechanisms have a characteristic of compact structure. The design of drive system often is limited by the environment condition and the factor of cost and technical lever. The step motor can receive digital signal directly and has the ability to response outer environment immediately and has no accumulation error, which often is used in driving system. In this driving system, open-loop control system is composed of stepping motor, which can satisfy the demand not only for control precision but also for the target of economic and practicality. On this basis, the analysis of stepping motor in power calculating and style selecting is also given. The analysis of kinematics anddynamics for object holding manipulator is given in completing the design of mechanical structure and drive system.Current industrial approaches to robot arm control treat each joint of the robot arm as a simple joint servomechanism. The servomechanism approach models the varying dynamics of a manipulator inadequately because it neglects the motion and configuration of the whole arm mechanism. These changes in the parameters of the controlled system sometimes are significant enough to render conventional feedback control strategies ineffective. The result is reduced servo response speed and damping, limiting the precision and speed of the end-effecter and making it appropriate only for limited-precision tasks. Manipulators controlled in this manner move at slow speeds with unnecessary vibrations. Any significant performance gain in this and other areas of robot arm control require the consideration of more efficient dynamic models, sophisticated control approaches, and the use of dedicated computer architectures and parallel processing techniques.In the industrial production and other fields, people often endangered by such factors as high temperature, corrode, poisonous gas and so forth at work, which have increased labor intensity and even jeopardized the life sometimes. The corresponding problems are solved since the robot arm comes out. The arms can catch, put and carry objects, and its movements are flexible and diversified. It applies to medium and small-scale automated production in which production varieties can be switched. And it is widely used on soft automatic line. The robot arms are generally made by withstand high temperatures, resist corrosion of materials to adapt to the harsh environment. So they reduced the labor intensity of the workers significantly and raised work efficiency. The robot arm is an importantcomponent of industrial robot, and it can be called industrial robots on many occasions. Industrial robot is set machinery, electronics, control, computers, sensors, artificial intelligence and other advanced technologies in the integration of multidisciplinary important modern manufacturing equipment. Widely using industrial robots, not only can improve product quality and production, but also is of great significance for physical security protection, improvement of the environment for labor, reducing labor intensity, improvement of labor productivity, raw material consumption savings and lowering production costs.There are such mechanical components as ball footbridge, slides, air control mechanical hand and so on in the design. A programmable controller, a programming device, stepping motors, stepping motors drives, direct current motors, sensors, switch power supply, an electromagnetism valve and control desk are used in electrical connection.Robot is the automated production of a kind used in the process of crawling and movin g piece features automatic device, which is mechanized and automated production process d eveloped a new type of device. In recent years, as electronic technology, especially compute r extensive use of robot development and production of hightech fields has become a rapidl y developed a new technology, which further promoted the development of robot, allowing robot to better achieved with the combination of mechanization and automation. Robot can replace humans completed the risk of duplication of boring work, to reduce human labor int ensity and improve labor productivity. Manipulator has been applied more and more widely, in the machinery industry, it can be used for parts assembly, work piece handling, loading a nd unloading, particularly in the automation of CNC machine tools, modular machine toolsmore commonly used. At present, the robot has developed into a FMS flexible manufacturin g systems and flexible manufacturing cell in an important component of the FMC. The mac hine tool equipment and machinery in hand together constitute a flexible manufacturing syst em or a flexible manufacturing cell, it was adapted to small and medium volume production , you can save a huge amount of the work piece conveyor device, compact, and adaptable. When the work piece changes, flexible production system is very easy to change will help e nterprises to continuously update the marketable variety, improve product quality, and better adapt to market competition. At present, China's industrial robot technology and its enginee ring application level and comparable to foreign countries there is a certain distance, applica tion and industrialization of the size of the low level of robot research and development of a direct impact on raising the level of automation in China, from the economy, technical cons iderations are very necessary. Therefore, the study of mechanical hand design is very meani ngful.关于现代工业机械手机器人是典型的机电一体化装置,它综合运用了机械与精密机械、微电子与计算机、自动控制与驱动、传感器与信息处理以及人工智能等多学科的最新研究成果,随着经济技术的开展和各行各业对自动化程度要求的提高,机器人技术得到了迅速开展,出现了各种各样的机器人产品。

Hand Column Type Power MachineFollow with our country the rapid development of industrial production, rapidly enhance level of automation, implementation artifacts of handling, steering, transmission or toil for welding gun, spraing gun, spanner and other tools for processing, assembly operations for example automation, should cause the attention of people more and more.Industrial robot is an important branch of industrial robots. It features can be programmed to perform tasks in a variety of expectations, in both structure and performance advantages of their own people and machines, in particular, reflects the people's intelligence and adaptability. The accuracy of robot operations and a variety of environments the ability to complete the work in the field of national economy and there are broad prospects for development. With the development of industrial automation, there has been CNC machining center, it is in reducing labor intensity, while greatly improved labor productivity. However, the upper and lower common in CNC machining processes material, usually still use manual or traditional relay-controlled semi-automatic device. The former time-consuming and labor intensive, inefficient; the latter due to design complexity, require more relays, wiring complexity, vulnerability to body vibration interference, while the existence of poor reliability, fault more maintenance problems and other issues. Programmable Logic Controller PLC-controlled robot control system for materials up and down movement is simple, circuit design is reasonable, with a strong anti-jamming capability, ensuring the system's reliability, reduced maintenance rate, and improve work efficiency. Robot technology related to mechanics, mechanics, electrical hydraulic technology, automatic control technology, sensor technology and computer technology and other fields of science, is a cross-disciplinary integrated technology.Current industrial approaches to robot arm control treat each joint of the robot arm as a simple joint servomechanism. The servomechanism approach models the varying dynamics of a manipulator inadequately because it neglects the motion and configuration of the whole arm mechanism. These changes in the parameters of the controlled system sometimes are significant enough to render conventional feedback control strategies ineffective. The result is reduced servo response speed and damping, limiting the precision and speed of the end-effecter and making it appropriate only for limited-precision tasks. Manipulators controlled in this manner move at slow speeds with unnecessary vibrations. Any significant performance gain in this and other areas of robot arm control require the consideration of more efficient dynamic models, sophisticated control approaches, and the use of dedicated computer architectures and parallel processing techniques.Manipulator institutional form is simple, strong professionalism, only as a loading device for a machine tools, special-purpose manipulator is attached to this machine. Along with the development of industrial technology, produced independently according to the process control to achieve repetitive operation, using range iswide "program control general manipulator", hereinafter referred to as general manipulator. General manipulator used to quickly change the working procedure, adaptability is stronger, so he is in constant transformation in the medium and small batch production of products are widely used.NO.1 The composition of the manipulatorManipulator is in the form of a variety of, some relatively simple, some more complex, but the basic form is the same, generally by the actuators, transmission system, control system and the auxiliary device.The actuator manipulator actuators, by the hand, wrist, arm, pillars. Hand is grasping mechanism, which is used to clamp and release artifacts, as a human finger, can complete staff of similar action. Is connected to the fingers and wrist arm components, can be up and down, left and right sides and rotary movement. Simple manipulator can not the wrist. Prop used to support the arm, can also according to need to make it move.The driving system movement of the actuator by the transmission system to achieve. Common mechanical transmission system of mechanical transmission, hydraulic transmission, pneumatic transmission and power transmission etc. Several forms. The control system of manipulator control system main function is to control the manipulator according to certain procedures, movement direction, position, speed, simple manipulator is generally not set special control system, only the stroke switch, relay, control valves and control circuit can realize dynamic transmission system, the executing agency action in accordance with requirements. Action complex manipulator should adopts the programmable controller, microcomputer control. NO.2 Classification and characteristics of the manipulatorRobots generally fall into three categories the first is general manipulator doesn't need manual operation. It is a kind of independence is not attached to a host device. It can according to the need of the task program, the operation of the provisions to complete. It is with the characteristics of common mechanical performance, also has general machinery, memory, intelligence of three yuan. The second is the need to do manually. Called Operating machine. It originated in the atom, military industry, first by Operating machine to complete a specific assignment, later to use radio signal Operating machine to explore the moon and so on. Used in the forging industry Operating machine falls under this category. The third kind is to use special manipulator, mainly attached to automatic machine or automatic line, used to solve machine tool material and workpiece to send up and down. This manipulator in a foreign country is called "the Mechanical Hand", it is in the service of the host, driven by the host; Except a few working procedures generally is fixed, so it is special.NO.3 The application of industrial manipulatorManipulator is in the process of mechanization, automation production, developed a kind of new type of device. In recent years, with electronic technology, especially the wide application of electronic computer, the robot's development and production has become a high technology developed rapidly in the field of an emerging technology, it promoted the development of the manipulator, make the manipulator can achievebetter with the combination of mechanization and automation.Manipulator although it is not as flexible as manpower, but it can have repeated work and labor, do not know fatigue, is not afraid of danger, snatch heavy weights strength characteristics such as larger than man, as a result, the manipulator has been brought to the attention of the many departments, and have been applied more and more widely.(1) Machine tools machining the workpiece loading and unloading, especially in automatic lathe, use common combination machine tools.(2) Widely used in the assembly operation, it can be used to assemble printed circuit board in the electronics industry, it can be in the machinery industry to assemble parts.(3) Can be in working conditions is poor, repetitive easy fatigue of the work environment, to instead of human Labour.(4) The development of the universe and the ocean.(5) Military engineering and biomedical research and test.Application of robots can replace people in dull, repetitive or heavy manual work, to realize mechanization and automation of production, instead of human in harmful environment of manual operation, improve labor condition, ensure the personal safety. In the late 1940 s, the United States in the nuclear experiments, firstly adopts manipulator handling radioactive materials, people in the security room to manipulate manipulator for various operation and experiment. After the '50 s, robots gradually extended to industrial production department, for use in high temperature, serious pollution of local leave work pieces and the loading and unloading materials, as auxiliary device in the machine tool automatic machine, automatic production line and processing center in the application, complete the material up and down or from libraries take put the knives and replace tool operations such as fixed procedure. Manipulator is mainly composed of hand and motion mechanism. Hand mechanism varies according to the usage situation and operation object, the common are holding, hold and the adsorption type etc. Motion mechanism usually driven by hydraulic, pneumatic, electric devices. Manipulator can be achieved independently of scaling, rotation and lifting movement, generally speaking, there are 2 ~ 3 degrees of freedom. Robots are widely used in machinery manufacturing, metallurgy, light industry and atomic energy etc.Manipulator is used in the production process automation with grab and move the workpiece is a kind of automatic device, it is in the process of mechanization, automation production, developed a new type of device. In recent years, with electronic technology, especially the wide application of electronic computer, the robot's development and production has become a high technology developed rapidly in the field of an emerging technology, it promoted the development of the manipulator, make the manipulator can achieve better with the combination of mechanization and automation. Robots can replace humans do dangerous, repeat the boring work, reduce human labor intensity and improve labor productivity. Manipulator have been applied more and more widely, it can be used for parts assembled in the machinery industry, processing the workpiece handling, loading and unloading,especially on the automatic CNC machine, combination machine tools more common use. At present, the manipulator has developed into a flexible manufacturing system of FMS and flexible manufacturing cell is an important component of FMC. The machine tool equipment and manipulator of a flexible manufacturing system or flexible manufacturing unit, it is suitable for medium and small batch production, can save a large workpiece delivery device, structure is compact, but also has a strong adaptability. When the workpiece changes, flexible production system is easy to change, is advantageous to the enterprise continuously updated marketable varieties, improve product quality, better adapt to the needs of the market competition. But at present our country's industrial robot technology and its engineering application level and foreign than there is a certain distance, scale and industrialization level is low, research and development of the manipulator has direct influence on raising the automation level of production in our country, from the consideration on the economic and technology is very necessary. Therefore, carries on the research design of the manipulator is very meaningful.NO.4 The development trend of manipulatorCurrent industrial applications of the manipulator gradually expanding, constantly improve the technology performance. Due to the short development time, it has a gradual understanding of process, the manipulator and a technically perfect step by step process, its development trend is:1.To expand the application of manipulator and processing industryAt present domestic robots used in mechanical industry more in cold working operations, while in the hot work such as casting, forging, welding, heat treatment less, and the application of assembly work, etc. So processing work items heavy, complicated shape and high environmental temperature, bring many difficulties to manipulator design, manufacture, it is need to solve the technical difficulties, make the manipulator to better service for processing work. At the same time, in other industries and industrial sectors, also will with the constant improvement of the industrial technology level, and gradually expand the use of the manipulator 2.Improve the work performance of the industry manipulatorManipulator in the working performance of the pros and cons, determines the application and production, it can normal manipulator working performance of the repetitive positioning accuracy and speed of work two indicators, decided to ensure the quality of manipulator can complete the operation of the key factors. Therefore to solve good working stability and rapidity of the manipulator's request, besides from solve buffer localization measures, should also be development meet the requirements of mechanical properties and low price of electro-hydraulic servo valve, servo control system was applied to the mechanical hand.3.Development of modular robotsVariable application manipulator from the characteristics of the manipulator itself, more adapted to the product type, equipment updates, many varieties, small batch, but its cost is high, the special manipulator and cheap, but the scope is limited. Therefore, for some special purpose, you need special design, special processing, thus improving the product cost. In order to adapt to the request ofthe application field of classify, the structure of the manipulator can be designed to the form of combination. Modular manipulator is a common parts according to the requirement of the job, select necessary to accomplish the function of the unit components, based on the base of combination, deserve to go up with adaptive control part, namely the manipulator with special requirements can be completed. It can simplify the structure, take into account the specificity and design on the use of generality, more in the series design and organization of standardization, specialized production, to improve quality and reduce cost of the manipulator, isa kind of promising manipulator4. Has a "vision" and "touch" of so-called "intelligent robots"For artificial has flexible operation and the need for judgment of the situation, industrial manipulator is very difficult to replace human labor. Such as in the working process of the accident, disorders and conditions change, etc., manipulator cannot be automatically distinguish correct, but to stop, after waiting for people to rule out accident can continue to work. As a result, people puts forward higher requirements on mechanical hand, hope to make it a "vision", "touch", etc, make it to the judgment, the choice of object, can be continuously adjusted to adapt to changing conditions, and can perform a "hand - eye coordination. This requires a computer can handle a lot of information, require them to exchange of information with machine "dialogue".This "vision", "touch" feedback, controlled by computer, is one part of the "smart" mechanism is called "intelligent robots". Is the so-called "smart" includes: the function of recognition, learning, memory, analysis, judgment. And recognition is through the "visual", "touch" and "hearing" feel "organ" of cognitive object. Which has the function of sensory robot, its performance is perfect, can accurately clamping arbitrary azimuth objects, determine an object, weight, work over obstacles, the clamping force is measured automatically, and can automatically adjust, suitable for engaged in the operation of the complex, precision, such as assembly operation, it has a certain development prospects.Intelligent robots is an emerging technology, the study of it will involve the electronic technology, control theory, communication technology, television technology, spatial structure and bionic mechanical discipline. It is an emerging field of modern automatic control technology. With the development of science and intelligent robots will replace people to do more work.工业机械手随着我国工业生产的飞跃发展,自动化程度的迅速提高,实现工件的装卸、转向、输送或是操持焊枪、喷枪、扳手等工具进行加工、装配等作业的自动化,应越来越引起人们的重视。

Khosla Abstract:A rapidly deployable manipulator system combines the flexibility of reconfigurable modular task. This article describes two main aspects of such a system, namely, the Reconfigurable Modular Manipulator System (RMMS)Robot manipulators can be easily reprogrammed to perform different tasks, yet the range of tasks that can be performed by a manipulator is limited by mechanicalstructure.Forexample, a manipulator well-suited for precise movement across the top of a table would probably no be capable of lifting the vertical direction. Therefore, to perform a given task,one needs to choose a manipulator with an appropriate mechanical structure.We propose the concept of a rapidly deployable manipulator system to address the above mentioned shortcomings of fixed configuration manipulators. As is illustrated in Figure 1, a rapidly deployable manipulator system consists of software and task.The central building block of a rapidly deployable system is a Reconfigurable Modular Manipulator System (RMMS). The RMMS utilizes a stock of interchangeable link and joint modules of various sizesand performance specifications. One such module is shown in Figure 2. By combining these general purpose modules, a wide range of special purpose manipulators can be assembled. Recently, there considerable interest in the idea of modular manipulators [2, 4, 5, 7, 9, 10, 14], for research applications as well as for industrial applications. However, most of these systems lack the property of reconfigurability, which is key to the concept of rapidly deployable systems. The RMMS is particularly easy to reconfigure thanks to its integrated quick-coupling connectors described in Section 3.Effective use of the RMMS requires, Task Based Design software. This software takes as input descriptions of the task and of the available manipulator modules; it generates as output a modular assembly configuration optimally suited to perform the given task. Several different approaches used successfully to solve simpli-fied instances of this complicated problem.A third important building block of a rapidly deployable manipulator system is a framework for the generation of control software. To reduce the complexity of softwaregeneration for real-time sensor-based control systems, a software paradigm called software assembly proposed in the Advanced Manipulators Laboratory at CMU.This paradigm combines the concept of reusable and reconfigurable software components, as is supported by the Chimera real-time operating system [15], with a graphical user interface and a visual programming language, implemented in OnikaA lthough the software assembly paradigm provides thesoftwareinfrastructure for rapidly programming manipulator systems, it does not solve the programming problem itself. Explicit programming of sensor-based manipulator systems is cumbersome due to the extensive amount of detail which must be specified for the robot to perform the task. The software synthesis problem for sensor-based robots can be simplified dramatically, by providing robust robotic skills, that is, encapsulated strategies for accomplishing common tasks in the robots task domain [11]. Such robotic skills can then be used at the task level planning stage without example of the use of a rapidly deployable system,consider a manipulator in a nuclear environment where it must inspect material and space for radioactive contamination, or assemble and repair equipment. In such an environment, widely varied kinematic (e.g., workspace) and dynamic (e.g., speed, payload) performance is required, and these requirements may not be known a priori. Instead of preparing a large set of different manipulators to accomplish these tasks—an expensive solution—one can use a rapidly deployable manipulator system. Consider the following scenario: as soon as a specific task is identified, the task based design software determinesthe task. This optimal configuration is thenassembled from the RMMS modules by a or, in the future, possibly by another manipulator. The resulting manipulator is rapidly programmed by using the software assembly paradigm and our library of robotic skills. Finally,the manipulator is deployed to perform its task.Although such a scenario is still futuristic, the development of the reconfigurable modular manipulator system, described in this paper, is a major step forward towards our goal of a rapidly deployable manipulatorsystem.Our approach could form the basis for the next generation of autonomous manipulators, in which the traditional notion of sensor-based autonomy is extended to configuration-based autonomy. Indeed, although a deployed system can it needs, it may still not be able to accomplish its task because the task is beyond the system’s physical capabilities. A rapidly deployable system, on the other task specifications and, with advanced sensing, control, and planning strategies, accomplish the task autonomously.2 Design of self-contained most industrial manipulators, the controller isa separate unit each of the joints of the manipulator. The large number of electrical connections and the non-extensible nature of such a system layout make it infeasible for modular manipulators. The solution we propose is to distribute the control become self-contained units which include sensors, an actuator, a brake, a transmission, a sensor interface, a motor amplifier, and a communication interface, as is illustrated in Figure 3. As a result, only six wires are required for power distribution and data communication.2.1 Mechanical designThe goal of the RMMS project is to in Figure 2), and one rotate joint module. The base module and the link module of the joint modules compactly fits a DC-motor, a fail-safe brake, a tachometer, a -line configuration respectively, but are identical internally. Figure 4 shows in cross-section the internal structure of a pivot joint. Each joint module includes a DC torque motor and 100:1The custom-designed on-board electronics are also designed according to the principle of modularity. Each RMMS module contains a motherboard which provides the basic functionality and onto which daughtercards can be stacked to add module specific functionality.The motherboard consists of a Siemens 80C166 microcontroller, 64K of ROM, 64K of RAM, an SMC COM20020 universal local area network controller with an RS-485 driver, and an RS-232 driver. The function of the motherboard is to establish communication with the RS-485 bus and to perform the lowlevel control of the module, as is explained in more detail in Section 4. The RS-232 serial bus driver allows for simple diagnostics and software prototyping.A stacking connector permits the addition of an indefinite number of daughtercards with various functions, such as sensor interfaces, motor controllers, RAM expansion etc. In our current implementation, only modules with actuators include a daughtercard. This card contains a 16 bit resolver to digital converter, a 12 bit AD converter to interface with the tachometer, and a 12 bit DA converter to control the motor amplifier; we ofthe-shelf motor amplifier (Galil Motion Control model SSA-880) to drive the DC-motor. For modules with more than one degree-of-freedom, for instance a wrist module, more than one such daughtercard can be stacked onto the same motherboard.3 Integrated quick-coupling connectorsTo make a modular manipulator be reconfigurable, it is necessary that the modules can be easily connected with each other. We between modules can be achieved by simply turning a ring in Figure 5, keyedflanges provide precise registration of the two modules. Turning of the locking collar on the male end produces two distinct motions: first the fingers of the locking ring rotate (with the collar) about 22.5 degrees and capture the fingers on the flanges; second, the collar rotates relative to the locking ring, while a cam mechanism forces the fingers inward to securely grip the mating flanges. A ball- transfer mechanism between the collar and locking ring automatically produces this sequence of motions.At the same time the mechanical connection is made,pneumatic and electronic connections are also established. Inside the locking ring is a modular connector that the middle. These correspond to matching female components on the mating connector. Sets of pins are wired in parallel to carry the 72V-25A power for motors and brakes, and 48V–6A power for the electronics. Additional pins carry signals for two RS-485 serial communication busses and four video busses. A plastic guide collar plus six alignment pins prevent damage to the connector pins and assure proper alignment. The plastic block rotate in the orientations LED in the female connector and eight photodetectors in the male connector.4 ARMbus communication systemEach of the modules of the RMMS communicates with a VME-based is done in a serial fashion over an RS-485 bus which runs through the length of the manipulator. We use the ARCNET protocol [1] implemented on a dedicated IC (SMC COM20020). ARCNET is a deterministic token-passing network scheme which avoids network collisions and guarantees each node its time to access the network. Blocks of information called packets may be sent from any node on the network to any one of theother nodes, or to all nodes simultaneously (broadcast). Each node may send one packet each time it gets the token. The maximum network throughput is 5Mbs.The first node of the network resides on the Figure 6. In addition to a VME address decoder, this card contains essentially the same find on a module motherboard. The communication between the VME side of the card and the ARCNET side occurs through dual-port RAM.There are two kinds of data passed over the local area network. During the manipulator initialization phase, the modules connect to the network one by one, starting at the base and ending at the end-effector. On joining the network, each module sends a data-packet to the with respect to the previous module. This information allows us to automatically determine the current manipulator configuration.During the operation phase, the the control mode—centralized or distributed. In centralized control mode, the torques for all the joints are computed on the VME-based real-time processing unit (RTPU), assembled into a data-packet by the microcontroller on the distributed control mode, on the other each module, the control loop can then be closed at a frequency much 400Hz. The modules still send sensor readings back to the the computation of the subsequent feed-forward torque.5 Modular and reconfigurable control softwareThe control software for the RMMS developed using the Chimera real-time operating system, which supports reconfigurable and reusable software components [15]. The software components used to control the RMMS are listed in Table 1. The trjjline, dls, and grav_comp componentsrequire the knowledge of certain configuration dependent parameters of the RMMS, such as the number of degrees-of-freedom, the Denavit-Hartenberg parameters etc. During the initialization phase, the RMMS interface establishes contact with each of the which order and orientation they assembled. For each module, a data file with a parametric model is read. By combining this information for all the modules, kinematic and dynamic models of the entire manipulator are built.After the initialization, the rmms software component operates in a distributed control mode in which the microcontrollers of each of the RMMS modules perform PID control locally at 1900Hz. The communication between the modules and the differ from the cycle frequency of the rmms software component. Since we use a triple buffer mechanism [16] for the communication through the dual-port RAM on the ARMbus or numerically..6 Seamless integration of simulationTo assist the user in evaluating whether an RMMS con- figuration can successfully complete a given task, we the TeleGrip robot simulation software from Deneb Inc., and runs on an SGI Crimson which is connected with the real-time processing unit through a Bit3 VME-to-VME adaptor, as is shown in Figure 6. A graphical user interface allows the user to assemble simulated RMMS configurations very much like assembling the real be tested and programmed using the TeleGrip functions for robot devices. The configurations can also be interfaced with the Chimera real-time softwarerunning on the same RTPUs used to control the actualRMMS simulation compared with the actual task execution.7 SummaryWe be assembled in a large number of different configurations to tailor the kinematic and dynamic properties of the manipulator to the task at by building kinematic and dynamic models of the manipulator; this is totally transparent to the user. To assist the user in evaluating whether a manipulator configuration is well suited for a given task, we part by DOE under grant DE-F902-89ER14042, by Sandia National Laboratories under contract AL-3020, by the Department of Electrical and Computer Engineering, and by The Robotics Institute, Carnegie Mellon University.The authors would also like to thank Randy Casciola, Mark DeLouis, Eric Hoffman, and Jim Moody for their valuable contributions to the design of the RMMS system.附件二:可迅速布置的机械手系统作者:Christiaan J.J.

1 英文文献翻译1.1 Cherry-harvesting robot1.1.1 IntroductionIn Japan, cherries are harvested carefully by human labor. As the harvesting season is short, the harvesting work is concentrated in a short time period and labor shortage tends to limit the farm acreage. Moreover, cherry trees are tall, and so the harvesting work must be conducted using pairs of steps. This makes harvesting dangerous and inefficient. To save on labor, a cherry-harvesting robot was manufactured for trial purposes and initial experiments were conducted. Research on fruit-harvesting robots has already been conducted (Kawamura etal., 1984; Harrell et al., 1990; Fujiura et al., 1990; Hanten et al.,2002). Many of the fruit-harvesting robots previously reported are equipped with a video camera. Fruit images are distinguished from the background by the difference in color or the spectral reflectance. The 3-D location of the fruit was calculated using binocular stereo-vision (Kawamura et al., 1985)or by visual feedback control (Kondo and Endo, 1989). Applications of a 3-D vision sensor have also been reported (Subrata etal., 1996; Gao et al., 1997). The 3-D vision sensor has the advantage that each pixel of the image has distance information.Making use of this advantage, the object can be recognized by the 3-D shape. As for the cherry-harvesting work, it is necessary to harvest the fruit while avoiding collisions with obstacles such as leaves and stems. To obtain a successful harvesting motion, detection of obstacles as well as the red ripe fruit is required. To achieve this, a 3-D vision system that has two laser diodes was manufactured. One of them emits a red beam and the other an infrared beam. To prevent the influence of the sunlight, position sensitive devices (PSDs) were used todetect the r eflected light. By blinking the laser beams at a high frequency, the signal components of the laser from PSDs were distinguished from that of the sunlight. The 3-D shape of the object was measured by scanning the laser beams and the red fruits were distinguished from other objects by the different cein the spectral-reflection characteristics between the red andinfrared laser beams. The robot needs to harvest correctly and efficiently without damaging the fruits and branches under the environment (temperature, sunshine, etc.) of the orchard. Many cherry trees are cultivated in rain-cover vinyl tents to protect against rain. A robot that works in the tent is not exposed to wind and rain. Cherry fruit, both for the fresh market and for processing, must be harvested with its peduncle.In the case of manual harvesting, therefore, farmers grip the upper part of the peduncle with their fingers, and lift it upward to detach it from the tree. For the same reason, the robot manufactured for the experiment also gripped the upper part of the peduncle just like farmers and lifted it upward to detach the peduncle from the tree.1.1.2 Materials and methodsThe robot consists of a manipulator 4 degrees of freedom (DOF), a 3-D vision sensor, an end effector, a computer, and a traveling device (Fig. 2). It is about 1.2m high, 2.3m wide, and 1.2m long. The 3-D vision sensor is attached to the manipulator to scan from different viewpoints by the motion of the manipulator. A vacuum is used to suck the fruit into the sucking pipe of the end effector.Cherry trees cultivated by the method of single trunk training distribute their fruits around the main trunk. In order to harvest a fruit while avoiding obstacles, such as leaves and trunks, the end effector needs to approach the fruit from the outside of the trunk. For this reason, in this study, we manufactured an articulated manipulator with an axis of up-down traverse and three axes of right-left turning, so that the fruits could be harvested in any direction (Fig. 2). The up-down traverse requires comparatively large force caused by the gravity. Therefore, it is driven by an AC servomotor (Yaskawa Electric, SGMAH-01BAA2C, rated power 100W, rated torque 0.318Nm, rated speed 3000min−1) and a screw mechanism (lead 10mm). Three axes of the right–left turning do not require large torque. Axes of the first and second right–left turning are driven by small AC servomotors (Yaskawa Electric, SGMAH-A5BAA21, rated power 50W, rated torque 0.159N m,rated speed 3000min−1) and harmonic reduction gears (reduction gear ratio100). The remaining axis of right–left turning is driven by a small DC motor with reduction gears. The manipulator is designed to be able to move round the circumference of the tree trunk so that notonly fruits on the front side of the trunk but also the fruits on the other side of the trunk could be harvested.Since the fruits are located around the tree trunk, if the vision sensor scans from one viewpoint, fruits beyond the trunk are hidden. To scan from different viewpoints, the 3-D vision sensor was attached to the second arm. The movement of the manipulator changed the location and directionof the 3-D vision sensor so that the dead angle becomes small.The 3-D vision sensor is equipped with a light projector, a photo detector, and a scanning device (Fig. 3). The light projector consists of an infrared laser module, a red laser module, cold mirrors, a half mirror, and two full-reflecting mirrors. The photo detector consists of two PSDs, a lens, and a red optical filter that weakens the influence of su nlight. The scanning device consists of a galvanometer scanner and a stepping motor. The galvanometer scanner scans vertically and the stepping motor scans horizontally. Red and infrared laser beams are united in the same optical axis by a cold mirror that transmits infrared light and reflects visible right. The beam is further split into two beams (each still including both wavelengths) by a half mirror. These two beams scan the object simultaneously. Light of the two beams reflected from the object is focused onto two PSDs. The distance from the 3-D vision sensor to the object is calculated by a triangulation method using the ratio of the currents of both electrodes of the PSDs. The laser beams emit blinking signals in order to eliminate the influence of sunl ight.By this method, reflected light is separated from the sunlight, thus resulting in continuous light. Infrared light with wavelengths about 700–1000 nm is reflected well by all parts of the cherry tree. On the other hand, red light at about 690 nm is n ot reflected well by unripe fruit, leaves, and stalks, but is reflected well by red ripe fruit. In this study, an infrared light beam of830 nm and a red light beam of 690 nm were used. The infrared laser beam (830 nm) measures the distance to each part of the cherry tree from the 3-D vision sensor and the red laser beam(690 nm) detects the red fruit to be harvested.As mentioned above, the laser beam is split into two beams. The 3-D vision sensor scans these two beams simultaneously, and two pixels were measured at once to increase the scanning speed. The number of pixels was 50,000 (250 in the vertical and 200 in the horizontal direction). The scan time was 1.5 s. The field of vision was 43.8◦ in vertical direction and 40.6◦ in horizontal direction. The effective range of the sensor was from170mmto 500mm. If the object was too far from the sensor, the detected light was weakened and the measuring accuracy was not good.The reflected light from these laser beams is detected by two PSDs, one for each beam. The signals from the PSDs include red and infrared components. To acquire the red and infrared signals separately, the red and infrared laser lights were emitted at a blinking frequency of 41.6 kHz with a phase shift of 90◦. Photoelectric currents from PSDs are amplified. Red and infrared signals are detected separately using lock-in amplifiers, which also eliminate the influence of ambient light. The 3-D vision sensor can be used even under sunlight, where the illuminance is 100 klx. A red image and an infraredimage are fed to the computer, and then a range image and segmentation are obtained.The range image is calculated by triangulation using the infrared signals from anode A and B of the PSD. Segmentation is obtained from the ratio between the infrared and red signals. Red fruits were distinguished from other objects such as leaves by the reflectivity of the red laser. However, the trunk as well as the fruits reflect a red laser beam. Therefore, it was distinguished from fruits using other methods. Fruits reflect with specula phenomenon. When they are scanned, the fruit center reflects the laser beam well. How- ever, this phenomenon does not occur at the trunk surface. The center of each fruitwas recognized using this specula phenomenon. When the center of a fruit is visible from the 3-D vision sensor, fruits could be recognized by this method. By processing these images, the location of red fruits and obstacles, such as leaves and trunks, could be recognized.Fig. 4 shows examples of the image. The range image was obtained by the method of triangulation using the infrared signals of the PSD. By processing the infrared, red, and the range images, the object was segmented into red fruits and others. The image in the right side shows the result of segmentation.Cherry fruit must be harvested with its peduncle attached. The tensile strength needed to detach the fruit was measured. The strength between the peduncle and the fruit was about 1N. On the other hand, the strength between the peduncle and the branch was about 2.5N. Therefore, if the fruit was pulled it would detach the peduncle and the fruit because the strength in that area isthe weakest. To harvest the fruit with its peduncle, a special end effector was used. It consisted of a fruit sucking device, an open-close mechanism, a back-and- forth mechanism, and a pair of fingers. It is about 80 mm high, 30 mm wide, and 145 mm long (Fig. 5). The vacuum pressure from the vacuum cleaner sucks the fruit so that the fruit position is fixed at the tip of the pipe. The fin ger can be opened or closed by the rotation of a servomotor attached on the end effector. After the fingers grasp the peduncle, the end effector is lifted up to remove the peduncle from the tree.Fig. 6 shows the motion of the end effector. First, the finger s are opened and retracted by the servomotors. Then, the end effector approaches a fruit and sucks it. After sucking the fruit, the fingers move halfway forward, and close halfway until the clearance between fingers becomes 5mm. In order to enclose only the target fruit, the fingers are equipped with soft rubber components for obstacle exclusion, so that other fruits may not enter between the fingers. It is necessary to grip the peduncle as near as possible to its root . Therefore, after the fingers are closed halfway, they move further forward. Then, they close completely and grasp the peduncle. Finally, the end effector moves upward to detach the peduncle. The end effector moves to the position above a fruit box, and the fingers open and release the fruit.……1.2 樱桃采摘机器人1.2.1 简介在日本,采摘樱桃是一项细致的人工劳动。

Hand Column Type Power MachineFollow with our country the rapid development of industrial production, rapidly enhance level of automation, implementation artifacts of handling, steering, transmission or toil for welding gun, spraing gun, spanner and other tools for processing, assembly operations for example automation, should cause the attention of people more and more.Industrial robot is an important branch of industrial robots. It features can be programmed to perform tasks in a variety of expectations, in both structure and performance advantages of their own people and machines, in particular, reflects the people's intelligence and adaptability. The accuracy of robot operations and a variety of environments the ability to complete the work in the field of national economy and there are broad prospects for development. With the development of industrial automation, there has been CNCmachining center, it is in reducing labor intensity, while greatly improved labor productivity. However, the upper and lower commonin CNCmachining processes material, usually still use manual or traditional relay-controlled semi-automatic device. The former time-consuming and labor intensive, inefficient; the latter due to design complexity, require more relays, wiring complexity, vulnerability to body vibration interference, while the existence of poor reliability, fault more maintenance problems and other issues.Programmable Logic Controller PLC-controlled robot control system for materials up and down movement is simple, circuit design is reasonable, with a strong anti-jamming capability, ensuring the system's reliability, reduced maintenance rate, and improve work efficiency. Robot technology related to mechanics, mechanics, electrical hydraulic technology, automatic control technology, sensor technology and computer technology and other fields of science, is a cross-disciplinary integrated technology.Current industrial approaches to robot arm control treat each joint of the robot arm as a simple joint servomechanism. The servomechanism approach models the varying dynamics of a manipulator inadequately because it neglects the motion and configuration of the whole arm mechanism. These changes in the parameters of the controlled system sometimes are significant enough to render conventional feedback control strategies ineffective. The result is reduced servo response speed and damping, limiting the precision and speed of the end-effecter and making it appropriate only for limited-precision tasks. Manipulators controlled in this manner move at slow speeds with unnecessary vibrations. Anysignificant performance gain in this and other areas of robot arm control require the consideration of more efficient dynamic models, sophisticated control approaches, and the use of dedicated computer architectures and parallel processing techniques.Manipulator institutional form is simple, strong professionalism, only as a loading device for a machine tools, special-purpose manipulator is attached to this machine.Along with the development of industrial technology, produced independently according to the process control to achieve repetitive operation, using range iswide "program control general manipulator", hereinafter referred to as general manipulator. General manipulator used to quickly change the working procedure, adaptability is stronger, so he is in constant transformation in the medium and small batch production of products are widely used.NO.1 The composition of the manipulatorManipulator is in the form of a variety of, some relatively simple, some more complex, but the basic form is the same, generally by the actuators, transmission system, control system and the auxiliary device.The actuator manipulator actuators, by the hand, wrist, arm, pillars. Hand is grasping mechanism, which is used to clamp and release artifacts, as a human finger, can complete staff of similar action. Is connected to the fingers and wrist arm components, can be up and down, left and right sides and rotary movement. Simple manipulator can not the wrist. Prop used to support the arm, can also according to need to make it move.The driving system movement of the actuator by the transmission system to achieve. Common mechanical transmission system of mechanical transmission, hydraulic transmission, pneumatic transmission and power transmission etc. Several forms.The control system of manipulator control system main function is to control the manipulator according to certain procedures, movement direction, position, speed, simple manipulator is generally not set special control system, only the stroke switch, relay, control valves and control circuit can realize dynamic transmission system, the executing agency action in accordance with requirements. Action complex manipulator should adopts the programmable controller, microcomputer control.NO.2 Classification and characteristics of the manipulatorRobots generally fall into three categories the first is general manipulator doesn't need manual operation. It is a kind of independence is not attached to a host device. It can according to the need of the task program, the operation of the provisions to complete. It is with the characteristics of common mechanical performance, also has general machinery, memory, intelligence of three yuan. The second is the need to do manually. Called Operating machine. It originated in the atom, military industry, first by Operating machine to complete a specific assignment, later to use radio signal Operating machine to explore the moon and so on. Used in the forging industry Operating machine falls under this category. The third kind is to use special manipulator, mainly attached to automatic machine or automatic line, used to solve machine tool material and workpiece to send up and down. This manipulator in a foreign country iscalled "the Mechanical Hand", it is in the service of the host, driven by the host; Except a few working procedures generally is fixed, so it is special.NO.3 The application of industrial manipulatorManipulator is in the process of mechanization, automation production, developed a kind of new type of device. In recent years, with electronic technology, especially the wide application of electronic computer, the robot's development and production has become a high technology developed rapidly in the field of an emerging technology, it promoted the development of the manipulator, make the manipulator can achievebetter with the combination of mechanization and automation.Manipulator although it is not as flexible as manpower, but it can have repeated work and labor, do not know fatigue, is not afraid of danger, snatch heavy weights strength characteristics such as larger than man, as a result, the manipulator has been brought to the attention of the many departments, and have been applied more and more widely.(1) Machine tools machining the workpiece loading and unloading, especially in automatic lathe, use common combination machine tools.(2) Widely used in the assembly operation, it can be used to assemble printed circuit board in the electronics industry, it can be in the machinery industry to assemble parts.(3) Can be in working conditions is poor, repetitive easy fatigue of the work environment, to instead of human Labour.(4) The development of the universe and the ocean.(5) Military engineering and biomedical research and test.Application of robots can replace people in dull, repetitive or heavy manual work, to realize mechanization and automation of production, instead of human in harmful environment of manual operation, improve labor condition, ensure the personal safety. In the late 1940 s, the United States in the nuclear experiments, firstly adopts manipulator handling radioactive materials, people in the security room to manipulate manipulator for various operation and experiment. After the '50 s, robots gradually extended toindustrial production department, for use in high temperature, serious pollution of local leave work pieces and the loading and unloading materials, as auxiliary device in the machine tool automatic machine, automatic production line and processing center in the application, complete the material up and down or from libraries take put the knives and replace tool operations such as fixed procedure. Manipulator is mainly composed of hand and motion mechanism. Hand mechanism varies according to the usage situation and operation object, the commonare holding, hold and the adsorption type etc. Motion mechanism usually driven by hydraulic, pneumatic, electric devices. Manipulator can be achieved independently of scaling, rotation and lifting movement, generally speaking, there are 2 ~ 3 degrees of freedom. Robots are widely used in machinery manufacturing, metallurgy, light industry and atomic energy etc.Manipulator is used in the production process automation with grab and move the workpiece is a kind of automatic device, it is in the process of mechanization, automation production, developed a new type of device. In recent years, with electronictechnology, especially the wide application of electronic computer, the robot's development and production has become a high technology developed rapidly in the field of an emerging technology, it promoted the development of the manipulator, make the manipulator can achieve better with the combination of mechanization and automation. Robots can replace humans do dangerous, repeat the boring work, reduce human labor intensity and improve labor productivity. Manipulator have been applied more and more widely, it can be used for parts assembled in the machinery industry, processing the workpiece handling, loading and unloading, especially on the automatic CNCmachine, combination machine tools more commonuse. At present, the manipulator has developed into a flexible manufacturing system of FMS and flexible manufacturing cell is an important component of FMC. The machine tool equipment and manipulator of a flexible manufacturing system or flexible manufacturing unit, it is suitable for medium and small batch production, can save a large workpiece delivery device, structure is compact, but also has a strong adaptability. When the workpiece changes, flexible production system is easy to change, is advantageous to the enterprise continuously updated marketable varieties, improve product quality, better adapt to the needs of the market competition. But at present our country's industrial robot technology and its engineering application level and foreign than there is a certain distance, scale and industrialization level is low, research and development of the manipulator has direct influence on raising the automation level of production in our country, from the consideration on the economic and technology is very necessary. Therefore, carries on the research design of the manipulator is very meaningful.NO.4 The development trend of manipulatorCurrent industrial applications of the manipulator gradually expanding, constantly improve the technology performance. Due to the short development time, it has a gradual understanding of process, the manipulator and a technically perfect step by step process, its development trend is:1. To expand the application of manipulator and processing industryAt present domestic robots used in mechanical industry more in cold working operations, while in the hot work such as casting, forging, welding, heat treatment less, and the application of assembly work, etc. So processing work items heavy, complicated shape and high environmental temperature, bring many difficulties to manipulator design, manufacture, it is need to solve the technical difficulties, make the manipulator to better service for processing work. At the same time, in other industries and industrial sectors, also will with the constant improvement of the industrial technology level, and gradually expand the use of the manipulator 2.Improve the work performance of theindustry manipulatorManipulator in the working performance of the pros and cons, determines the application and production, it can normal manipulator working performance of the repetitivepositioning accuracy and speed of work two indicators, decided to ensure the quality of manipulator can complete the operation of the key factors. Therefore to solve good working stability and rapidity of the manipulator's request, besides from solve buffer localization measures, should also be development meet the requirements of mechanical properties and low price of electro-hydraulic servo valve, servo control system was applied to the mechanical hand.3.Development of modular robotsVariable application manipulator from the characteristics of the manipulatoritself, more adapted to the product type, equipment updates, many varieties, small batch, but its cost is high, the special manipulator and cheap, but the scope is limited. Therefore, for some special purpose, you need special design, special processing, thus improving the product cost. In order to adapt to the request ofthe application field of classify, the structure of the manipulator can be designed to the form of combination. Modular manipulator is a common parts according to the requirement of the job, select necessary to accomplish the function of the unit components, based on the base of combination, deserve to go up with adaptive control part, namely the manipulator with special requirements can be completed. It can simplify the structure, take into account the specificity and design on the use of generality, more in the series design and organization of standardization, specialized production, to improve quality and reduce cost of the manipulator, is a kind of promising manipulator4. Has a "vision" and "touch" of so-called "intelligent robots"For artificial has flexible operation and the need for judgment of the situation, industrial manipulator is very difficult to replace human labor. Such as in the working process of the accident, disorders and conditions change, etc., manipulator cannot be automatically distinguish correct, but to stop, after waiting for people to rule out accident can continue to work. As a result, people puts forward higher requirements on mechanical hand, hope to make it a "vision", "touch", etc, make it to the judgment, the choice of object, can be continuously adjusted to adapt to changing conditions, and can perform a "hand - eye coordination. This requires a computer can handle a lot of information, require them to exchange of information with machine "dialogue".This "vision", "touch" feedback, controlled by computer, is one part of the"smart" mechanism is called "intelligent robots". Is the so-called "smart" includes: the function of recognition, learning, memory, analysis, judgment. And recognition is through the "visual", "touch" and "hearing" feel "organ" of cognitive object.Which has the function of sensory robot, its performance is perfect, can accurately clamping arbitrary azimuth objects, determine an object, weight, work over obstacles, the clamping force is measured automatically, and can automatically adjust, suitable for engaged in the operation of the complex, precision, such as assembly operation, it has acertain development prospects.Intelligent robots is an emerging technology, the study of it will involve the electronic technology, control theory, communication technology, television technology, spatial structure and bionic mechanical discipline. It is an emerging field of modern automatic control technology. With the development of science and intelligent robots will replace people to do more work.工业机械手随着我国工业生产的飞跃发展,自动化程度的迅速提高,实现工件的装卸、转向、输送或是操持焊枪、喷枪、扳手等工具进行加工、装配等作业的自动化,应越来越引起人们的重视。
