As we know,now there are more and more people using electric tools in daily life,to help them do much work with less time.Maybe people will even have their own robots in their home in the future.Robots will help people do a lot of human work,like cleaning the house,doing the laudry,taking people to work,and even cooking for them.As a result ,people needn't spend too much time on the work ,so they can save a lot of time to do what they want to do.I think people will live longer and more freely!
