A lot of science-fiction writers wrote stories about household robots and the future.
Many things came true but we are still waiting for robots to cater to all our needs.
Scientists have not yet given robots the ability to think but they are working on it.
They have made a robot which can walk, run and climb stairs. It also looks like a human with a human-like skin covering.
The biggest obstacle for robots is the language.
So scientists are still unsure whether we will have robot assistants which can speak.
