课前预习作业

Ⅰ. 机器人发展史

早在三千多年前的西周时代，我国就出现了能歌 善舞的木偶，称为“倡者”，这可能是世界上最早的“机器人”。上世纪五六十年代，出现第一代机器人，它属于“示教再现”(Teach-in/playback)型机器人，只具有记忆、存储能力，按相应程序重复作业，但对周围环境基本没有感知与反馈控制能力。进入80年代，出现了第二代机器人——有感觉的机器人。它能够获得作业环境和作业对象的有关信息，进行一定的实时处理作业，在工业生产中得到广泛应用。第三代机器人是目前正在研究的“智能机器人”。它不仅具有更加完善的环境感知能力，而且还具有逻辑思维、判断和决策能力，可根据作业要求与环境信息自主进行工作。
