7、也能在装配线上工作，如安装印刷电路板上电子元器件。这样，人们就能够从这种单调工作中解脱出来。机器人还能拆除炸弹，为伤残人士服务，为我们社会做各种各样工作。第17页第17页 A robot is a reprogrammable, multifunctional manipulator designed to move parts, materials, tools, or special devices through variable preprogrammed locations for the performance of a variety of different tasks. 机器

8、人是一个能够重复编程、多功效工作机构，能够在各个预编程位置移动零件、材料、工具或其它特殊装置，完成各种不同工作。第18页第18页 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 pars, spray painting, or welding. These preprogrammed loca

9、tions are stored in the robots memory and are recalled later for continuous operation. 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 industial robot is very much like

10、a computer. 关于，至于第19页第19页 预编程位置是指机器人完毕工作时必须遵循路径。在一些预编程位置，机器人会停下来进行一些操作，比如安装零件、喷漆或焊接。这些预编程位置存储在机器人存储中，以便随时调出进行连续操作。假如工作要求改变了，这些预编程位置连同其它编程数据也随之改变。这些编程特性使得工业机器人与计算机非常类似。第20页第20页 The robotic system can also control the work cell of the operating robot. The work cell of the robot is the total venvironme

11、nt in which the robot must perform its task. Included within this cell may be the robot manipulator, controler, a work table, safety features, or a conveyor. In addition, signals from outside devices can communicate with the robot. 第21页第21页 机器人系统能够控制工作机器人工作单元。机器人工作单元是机器人执行任务时工作环境。工作单元包括机器人机械手、控制器、工作

12、台、安全装置以及传动装置。另外，机器人应当能与外界信号进行交流。第22页第22页 The 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. The base of the manipulator is usually fixed

13、 to the floor of the work area. Sometimes, though, the base may be movabie. In this case, the base is attached to either a rail or a track, allowing the manipulator to be moved from one locationg to anther. 第23页第23页 机器人机械手完毕机器人系统详细工作，它包括两个部分：机械部分和附属部分。附属部分安装在机械手基座上。基座固定在工作现场地板上。但有时基座也是能够移动，在这种情况下，基座

14、安放在轨道上，用于把机械手从一个位置移到另外位置。第24页第24页 The appendage is the arm of the robot. It can be either a straight, movable arm or a jointed arm and gives the manipulator its various axes of motion. The jointed am is also known as an articulated arm. At the end of the arm, a wrist is connected. The wrist is made

15、up of additional axes and a wrist flang. The wrist flang allows the robot user to connect different tooling to the wrist for different jobs. 第25页第25页 从属部分是机器人手臂。它可能是一个直能够移动手臂，也可能是一个铰接手臂，为机械手提供多根工作轴。铰接手臂也就是相关节连接手臂。手臂端部连有一个手腕。手腕装在另一根轴上并装有法兰盘。在法兰盘上能够联接不同工具，完成不同工作。第26页第26页The manipulators axes allow it

16、to perform work within a certain area. This area is called the work cell of the robot, and its size corresponds to the size of the manipulator. As the robots physical size increases, the size of the work cell must also increase. 第27页第27页机械手上轴允许机械手在一个特定区域里工作。这个区域叫做机器人工作单元，它大小取决于机械手大小。假如机器人尺寸增长，工作单元尺寸

17、也会增长。第28页第28页 The movement of the manipulator is controlled ktueit制动器,传动装置,执行机构 by actuators, or drive systems. They allow 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 convened to mechanic

18、al power by various mechanical drive 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 chains, gears, and ball screws. 第29页第29页 机械手运动由驱动器或驱动系统控制。它们驱动各轴在工作单元内旋转。驱动系统能够是电力、液压，也能

The rser can program the movements of the manipulator into the controller through the

20、use of a hand-held teach pendant. This information is stored in the memory of the controller for later recall.第31页第31页 控制器用于控制机械手运动和工作单元内外部设备。能够通过悬挂手持键盘把机械手运动程序输入控制器。这些数据存储在控制器内存中，以备未来调用。第32页第32页 The controller is also required to communicate with peripheral equipment within the work cell. For examp

21、le, a controller has an input line. When the machine cycle is completed, the input line turns on, telling the controller to position the manipulator so that it can pickup the finished part. Then, a new part is picked up by the manipulator and placed into the machine. Next, the controller signals the

22、 machine to start operation. 第33页第33页 控制器还要能与工作单元内外部设备进行通信。比如，控制器有一条输入线路。加工完毕时输入线路连通，告诉控制器让机械手在指定位置挑出加工好零件。机械手把一个新零件送入机器后，控制器发出信号，重新开始加工。第34页第34页 The controller can send electric signals over communication lines. This two-way communication and operation of the system. The controller also has the job of communicating with the different plant computers. The communication link establishes the robot as part of a computer-assisted manufacturing(CAM) SYSTEM. The microprocessor-based systems operate in conjunction with solid-state memory devices. These memory devices may be magnetic bubbles, rand
