课前预习
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。

Will robots do housework for us?
日常家务繁重而琐碎，许多人都希望能有机器人帮助他们。如今这已不再是梦想了！日本已经成功研制出了一款能做家务的机器人。让我们去见识一下吧！
Are you tired of doing housework? Here is good news for you.
A robot named AR has been developed (开发) in Japan. The robot is 155 cm tall and weighs 130 kg. It moves around on wheels. The robot is able to clean up rooms, put away dishes from a dining table and pick up shirts and put them in a washing machine. It can also move furniture in order to sweep the floor.
The robot is different from the old ones. It can tell the differences between solid objects and soft things. It is also able to learn from failures and change its behavior patterns (模式).
Now AR’s movements are not perfect, but it is believed that after more improvements (改善), it will become people’s real housework helper in the future.
be tired of sth. / doing sth.意为“对……厌烦”。例如：
He’s tired of the same breakfast.
I’m tired of talking to him.
