A robot is a machine. But it is not just any machine. It is a special kind of machine. It is a machine that moves. It follows instructions. The instructions come from a computer. Because it is a machine, it does not make mistakes. And it does not get tired. And it never complains. Unless you tell it to!
Robots are all around us. Some robots are used to make things. For example, robots can help make cars. Some robots are used to explore dangerous places. For example, robots can help explore volcanoes. Some robots are used to clean things. These robots can help vacuum your house. Some robots can even recognize words. They can be used to help answer telephone calls. Some robots look like humans. But most robots do not. Most robots just look like machines.
Long ago, people imagined robots. But nobody was able to make a real robot. The gist real robot was made in 1961. It was called Unimate. It was used to help make cars. It looked like a giant arm.
In the future, we will have even more robots. They will do things that we can’t do. Or they will do things that we don’t want to do. Or they will do things that are too dangerous for us. They will help make life better.
