Robots are mechanical or virtual agents, usually electro-mechanical machines guided by a computer program or electronic circuity. By mimicing a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own. (Wikipedia)

When people think of robots, they are not amused by the human-like automated beings. They are more likely to be fearful, as the "war of the worlds" would have us believe.
