Can robots do more harm than good?

Nowadays we see the fast expansion of robot technologies. We have robots to work on the plants and factories, to work in hospitals and museums, and even to help us at homes.

But despite the fact that they do really make our life more easy, robots can cause a number of problems. The first disadvantage that worries a lot of people is that the robots take peoples jobs. Also a robot is a machine that has no pity or sympathy they only follow their program - it means that cannot adjust to the changing real life situations and because of that can even harm people.
