A robot is a special kind of machine. Because it is a machine, it does not make mistakes. And it does not feel tired. They can do many things. For example, robots can help to make cars and do some dangerous work for people. They can also help to clean things. Over 2,000 years ago, a famous poet imagined robots. The poet’s name was Homer. They cleaned things and they made things. But they were not real. Nobody could make a real robot at that time. The first real robot was made in 1961. Its name was Unimate. It was used to help make cars. It looked like a very big arm. In the future, we will have more robots. They will do things that we can’t do or we don’t want to do. Or they will do things that are too dangerous for us.
