Lots of scientists are studying robots today. Many robots don't always look like people. Some are like big machines, and some are nothing but long arms. However, modern robots aresmart. Some can solve problems on their own.
Robots are more and more useful and important in our life. They help us a lot. In factories,robots can help people do a lot of work. They work faster and do not need a rest. People will feelbored if they do the same job again and again, but robots will not. They can work in somedangerous places where people cannot.
Robots are useful in our homes, too. They can help us do some cooking. They can help theblind people read newspapers, help the old people move some heavy things and so on. If wehave some other problems, we can also ask them for help.
However, robots are not so clever as people. They cannot think like us. If we do not "teach"them how to do things first, they can do nothing.
It's possible that we will have our own robots, and they will help us to do more things in thefuture.
