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.
By this definition, however, a washing machine is also a robot. The wash and rinse cycles are programmable and the machine moves material in rotary motions. Therefore, a definition of an industrial robot must include the following key words: programmable manipulator, end-effector, factory work, and stand-alone operation. 然而根据这一定义，洗衣机同样也是一个机器人， 因为清洗和漂净周期是可编程的，洗衣机作旋转运 动移动被清洗的衣物。因此，工业机器人的定义必 须包括如下关键词：可编程的操纵器、终端执行器、 工厂作业、独立完成作业。 by this definition 根据该定义
