I think the robots doesn't make our lives better everything , because something humans can do it but something can't do. Must be ordered with robots such as medical robots it can work with high resolution than humans do , detection of diseases in the body or a part of surgery. Robots for dangerous areas , fire fighting robots and bomb detection robots for the safety of humans. The robots used in research and exploration in areas that are far away and beyond the ability of humans. Or the robots industry to quickly and precisely to work because some of the work is dangerous and risky. Disadvantages of the robots is expensive. I think in our daily life we don't have to use all of the robots. We can do the housework and cooking by ourselves. We should use a robots in a way that is useful to most.
