When we watch movies about the future, we sometimes see robots. They are usually like human servants. They help with the housework and do jobs like working1 dirty or dangerous places.
Today there are already robots working in factories. Some2 help to build cars, and they do simple jobs over and over again. Fewer people3such jobs in the future because they are boring, but robots will never get bored.
Scientists are now trying4robots look like humans and do the same things as we do. Some robots in Japan can walk and dance. They are fun to watch. However, some scientists believe that5we can make robots move like people, it will be difficult to make them really think like a human. For example, scientist James White thinks that robots will never be able to wake up and know where they are. But many scientists disagree with Mr. White. They think that robots will even be able to talk like humans625 to 50 years.
Some scientists believe that there will be more robots in the future. However, they agree it may take 7years. These new robots will have many different shapes. Some will look like humans, and8 might look like animals. In India, for example, scientists made robots9look like snakes. If buildings fall down with people inside, these snake robots can help look for people under the buildings. This was not possible 20 years ago, but computers and rockets also seemed10100 years ago. We never know what will happen in the future!
