I totally agree with the idea that robots will become very useful to humans in the future .Firstly ,home robots will be able to help us do all of our housework cleaning the house,doing the dishes ,doing the laundry,making the bed,doing the gardening and feeding the pets.Secondly,robots will be able to do dangerous work for humans.For example,worker robots will be able to build space stations on many other planets.Finally ,robots will be able to help sick people because thay can find healthy problem quickly.For the above reasons, I think that robots will be useful in our future.
