Why there won't be a robot uprising any time soon

When you read the word'robot', what comes into your mind? Most people think of a'metal man', a large humanoid figure with a square head, rather like the Tin Man in the film The Wizard of Oz or R2D2 in Star Wars. But if you ask people whether they have come across a robot in their own lives, they will usually describe a robot vacuum cleaner, or lawnmower. Successful robots keep it simple. Robots lawnmowers and vacuum cleaners are really not amazingly intelligent.
