The term “reprogrammable” implies two things: The robot operates according to a written program, and this program can be rewritten to accommodate a variety of manufacturing tasks. The term “multipurpose” 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 perform certain basic tasks more quickly and accurately than humans, they are being increasingly used in various manufacturing industries.1.What industrial robots can do for people?Industrial robots manipulate parts or tools to perform manufacturing tasks such as material handing,welding,spray painting,or assembly;automated guided vehicles are used for transporting materials in factories and warehouses.2.What are the advantages of robots?igue.Robots perform repetitive,high-precision operations 24 hours a day without fat3. What parts are made up of the robot?A robot is made up of sensors,actuators,and computatlonal elements(a microprocessor).4．What does t he term “reprogrammable” impl y?The term “reprogrammable”implies two things: The robot operates according to a written program, and this program can be rewritten to accommodate a variety of manufacturing tasks.5.Why are robots widely used over the past two decades?Because robots can perform certain basic tasks more quickly and accurately than humans, they are being increasingly used in various manufacturing industries.四.Read the following passage and t ranslate the underlined phrases and sentences into Chinese.（5*4=20）Classification of Robots1.Industrial robots vary widely in size, shape, number of axes, degrees of freedom, and design configuration. Each factor influences the dimensions of the robot’s working envelope 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 from point to point, and the cycle is repeated continuously. 2.The variable-sequence robot can be programmed for a specific sequence of operations but can be reprogrammed to perform another sequence of operation.3.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. 4.The numerically controlled robot is programmed and operated much like a numerically controlled machine. The robot is servo-controlled by digital data, and its sequence of movements can be changed with relative ease.5.Intelligent Robot. The intelligent robot is capable of performing some of the functions and tasks carried out by human beings. It is equipped with a variety of sensors with visual and tactile capabilities.1. 工业机器人在尺寸、形状、轴的数量、自由度、设计构型等方面广泛的变化。

1、In recent years the performance requirements for process plant have become increasingly difficult to satisfy.(近年来，对过程系统的性能改善需求变得越来越困难.)2、In fact, without process control it would not be possible to operate most modern processes safely and profitably (有利的), while satisfying plant quality standards.(实际上，对于大多数现代工业，要满足安全、高效，产品质量的要求，没有控制系统是不可能的)3、It is assumed that the inlet and outlet flow rates are identical (相同的) and that the liquid density ρ(rho) remains consant,that is, the temperature variations are small enough that the temperature dependence of ρcan be neglected.(假设输入和输出流量率是相等的，并且液体密度保持恒定,也就是说温度变化足够小，密度对温度的影响可以忽略不计)4、However, increased volume of tankage would be an expensive solution for an industrial plant due to the increased capital costs of the larger tank.(然而，体积增加使得开支增加，会使工厂系统的解决方案变得更加昂贵. )5、Note that in feedforward control, the controlled variable T is not measured.(注意的是，在前馈控制中，被控变量T是没有被测量的.)6、The reduction of system error is merely (仅仅) one of the many important effects that feedback may have upon a system.(减少系统误差只是反馈对系统产生的重要作用之一)7、In a practical control system, G and H are functions of frequency, so the magnitude of 1+GH may be greater than 1 in one frequency range but less than 1 in another.(在实际的控制系统中，G和H都是频率的函数，因此1+GH的幅值在一种频段下可能减小系统的增益，而在另一频段下又可能增大系统的增益)8、It can be demonstrated that one of the advantages of incorporating (包含) feedback is that it can stabilize an unstable system. (可以证明，加入反馈的好处之一是能够使不稳定的系统稳定。

应用于此方法的基本定律是基尔霍夫第一定律，基尔霍夫第一定律指出：一个闭合回路中的电压代数和为0，换句话说，任一闭合回路中的电压升等于电压降。

网孔分析指的是：假设有一个电流——即所谓的回路电流——流过电路中的每一个回路，求每一个回路电压降的代数和，并令其为零。

2: P17Alternatively,suppose that there had been attached to each pilot’s seat an electronic device that pr ovided an output voltage which is V1when the seat is occupied and V2when the seat is not occup ied.Let us attach the designation“true”to the voltage level V2so that the level V1is“false”.Let us further construct an electric circuit with two sets of input terminals and one set of output termi nals.The circuit is to have the property that the output voltage will be V2if and only if both inputs ,i.e.,one input AND simultaneously the other,are at the level V2.Otherwise the output is V1 Finally let us connect the inputs to the devices on the chairs of pilots A and B and arrange that an alarm bell,connected to the output Z,respond when the output is V2(“true”)and not otherwise. We have then constructed a circuit which performs the AND operation and is capable of making the logical deduction that the plane is unpiloted when,indeed,both pilots leave the cockpit换句话说，假设每一位飞行员座位下面有一个电子装置，当座位上有人时，其输出电压为V1，当座位上无人时，其输出电压为V2。

UNIT5 A 直流电机分类现在可以买到的直流电机基本上有四种：⑴永磁直流电机，⑵串励直流电机，⑶并励直流电机，⑷复励直流电机。

每种类型的电动机由于其基本电路和物理特性的不同而具有不同的机械特性。

永磁直流电机永磁直流电机，如图1-5A-1所示，是用与直流发电机同样的方法建造的。

永磁直流电机用于低转矩场合。

当使用这种电机时，直流电源与电枢导体通过电刷/换向器装置直接连接。

磁场由安装在定子上的永磁磁铁产生。

永磁磁铁电机的转子是绕线式电枢。

这种电机通常使用铝镍钴永磁合金或陶瓷永磁磁铁而不是励磁线圈。

铝镍钴永磁合金用于大功率电机。

陶瓷永磁磁铁通常用于小功率、低速电机。

陶瓷永磁磁铁抗退磁性能高，但它产生的磁通量较低。

磁铁通常安装在电机外壳里边，在安装电枢前将其磁化。

永磁电机相对于常规直流电机有几个优点。

优点之一是减少了运行损耗。

永磁电机的转速特性类似于并励式直流电机的转速特性。

永磁电机的旋转方向可通过将电源线反接来实现。

串励式直流电动机直流电机电枢和激磁电路的连接方式确定了直流电机的基本特性。

每一种直流电机的结构与其对应的直流发电机的结构类似。

大部分情况下，二者的唯一区别在于发电机常作为电压源，而电动机常作为机械能转换装置。

串励式直流电动机，如图1-5A-2所示，电枢和激磁电路串联连接。

仅有一个通路供电流从直流电压源流出。

因此，激磁绕组匝数相对少、导线直径大，以使激磁绕组阻抗低。

电机轴上负载的变化引起通过激磁绕组电流的变化。

如果机械负载增加，电流也增加。

增加的电流建立了更强的磁场。

当负载从零增加到很大时，串励式电机的转速从很高变化到很低。

由于大电流可以流过低阻抗的激磁绕组，串励式电动机产生一个高转矩输出。

串励式电动机用于启动重负载，而速度调节并不重要的场合。

一个典型应用是车辆启动电机。

并励式直流电动机并励式直流电动机是最常用的一种直流电机。

如图1-5A-3所示，并励式直流电动机的激磁绕组与电枢绕组并联连接。
