People began to make robots about several hundred years ago. In the past, some of the early ones looked like animals or humans. However, they couldn’t talk and were pretty dumb. They worked like clocks and did the same things over and over.

Now modem robots don’t always look like people. Some are like big machines,and others are nothing but long arms attached to boxy (箱子般四方的) bodies. However, modem robots are smart. Some can solve problems on their own. Their brains are computers and their eyes are sensors (传感器). Motors (发动机) help them move.

In the future, robots will learn from their mistakes more than they do now.They will be smarter. It’s possible that we will have robot judges, robot household workers,and robot factory workers.

Robots will help people to do more things.
