I agree with the idea that in the future robots will be useful to us. Firstly, we will no longer have to do all of housework like cleaning, sweeping, washing and so on because home robots will be able to help us. Secondly, we will not have to deal with some dangerous works since robots will support us. They can build houses in the air, fix electrical problems and discover the life under the oceans, in the space and on other planets. Moreover, with the artificial intelligent, they will help us a lot in studying science and technology, so new inventions will be given. All in all, robots will be a magical thing if we use them in the right way.
