文档介绍：Lesson 27 Industrial Robots 工业机器人 There are variety of definitions of the term robot .Depending on the definition used ,the number of robot installations worldwide varies widely .Numerous single-purpose machines are used in manufacturing plants that might appear tobe robots .These machines are hardwired to perform a single function and cannot be reprogrammed to perform a different function .Such single-purpose machines donot fit the definition for industrial robots that is ing widely accepted .This definition was developed by the Robot Institute of America .有许多关于机器人这个术语的定义。采用不同的定义,全世界各地机器人的数量就会发生很大的变化。在制造工厂中使用的许多单用途机器可能会看起来像机器人。这些机器是硬连线的,不能通过重新编程的方式去完成不同的工作。这种单用途的机器不能满足被人们日益广泛接受的关于工业机器人的定义。这个定义是由美国机器人协会提出的:A robot isa reprogrammable multifunctional manipulator designed to move material ,parts ,tools ,or specialized devices through variable programmed motions for the performance ofa variety of tasks .机器人是一个可以改编程序的多功能操作器,被设计用来按照预先编制的、能够完成多种作业的运动程序运送材料、零件、工具或者专用设备。 Notes that this definition contains the words reprogrammable and multifunctional .It is these two characteristics that separate the true industrial robot from the various single-purpose machines used in modern manufacturing firming .The term “ reprogrammable ” implies two things: The robot operates according toa written program ,and this program can be rewritten to modate a variety of manufacturing tasks .注意在这个定义中包含有“可以
