Unit 2 Industrial Robots 工业机器人-- KR 3 工业机器人 Dialogue Topical introduction: Tom and Mary are now visiting an industrial robot show in a university. A young girl named Marcy is in charge of showing the visitors around. Marcy : Ladies and gentlemen, e to our industrial robot show. I ’ m Marcy Margaret. My job is to show you around . You can ask me about anything you do not understand. Mary: How interesting to see so many kinds of robots here.

But what makes robots able to work for us so marvelously ? ? spray painting 喷涂 marvelously 奇迹般地,奇异地? Marcy: It’ s nothing else but the computer programs . Robots are a programmable mechanical manipulator . Being programmed with human instructions, they can move along several directions and do factory work usually done by human beings. ? Mary: Oh, that ’ s wonderful. But what ’ s the difference between robot and my handy calculator or my home washing machine, now that all of them belong to some reprogrammable mechanical manipulator . ? programmable mechanical manipulator 可编程机械装置? Marcy: Okay, it ’ s a clever question. But I think, here you mix a robot with an ordinary washing machine because you forget a robot can do a stand-alone operation , that is, rather independent jobs , while a washing machine can ’ t. So, when we talk about industrial robots, we mean a machine or device, which
