I totally agree that robot will be an essential part of our lives in the future. The home robots will be stayed at every home because of its convenience. They will help us do almost task of housework such as cleaning the floor, washing the dishes, putting out the rubbish, etc. It can join a hand to help the mums take care of their babies. Beside, some worker robots can replace us do the dangerous jobs. We can be safer and safer. We also can concentrate on researching and studying works in order to develop our society and humanity.
