What comes into your mind when you think about robots? Do you imagine armies of evil metal monsters planning to take over the world? Or, perhaps of mechanical men who have been created as guards or soldiers by a mad genius? Or maybe you think of man- like robots who act, think, and look like human beings. In fact robots like these have more to do with science fiction films than with real life. In the real world robots are machines that do jobs which otherwise have to be done by people. Robots either operate by themselves or under the control of a person.
In a car factory, for example, robot machinery can put together and paint car bodies. On the sea bed remotecontrolled(遙控)underwater machines with mechanical arms can perform tasks too difficult for divers. Robot spacecraft can explore the solar system and send back information about planets and stars.
Many robots have computer brains. Some robots are fitted with cameras , sensors, and microphones which enable them to see, to feel, and to hear. And some robots can even produce electronic speech.
All this does not mean that a robot can think and behave like a human being. Present day robots have to be programmed with a good deal of information before they can carry out even simple tasks.
