Robots will be very useful in the future. There are many diffrent robots with many functions. For example, home robots can do all house work and recognise our faces. Teaching robots can teach in the classes. Worker robots can even build big buildings. Doctor robots can help sick people. They will be able to do many things like humans but they won't be able to play football or drive a car. They will play an important role and they will be very wonderful in the future.
