The image usually thought of by the word robot is that of a mechanical
being, somewhat human in shape. Common in science fiction, robots are generally

people may have of a robotized world over which they cannot keep control. The
history of real robots is rarely as dramatic, but where developments in robotics
may lead is beyond our imagination.
Robots exist today. They are used in a relatively small number of
factories located in highly industrialized countries such as the United States,
Germany, and Japan. Robots are also being used for scientific research, in
military programs, and as educational tools, and they are being developed to aid
people who have lost the use of their limbs. These devices, however, are for
the most part quite different from the androids, or humanlike robots, and other
robots of fiction. They rarely take human form, they perform only a limited
number of set tasks, and they do not have minds of their own. In fact, it is

automated systems.
Although the term robot did not come into use until the 20th century,
the idea of mechanical beings is much older. Ancient myths and tales talked
about walking statues and other marvels in human and animal form. Such objects
were products of the imagination and nothing more, but some of the mechanized
figures also mentioned in early writings could well have been made. Such
figures, called automatons, have long been popular.
For several centuries, automatons were as close as people...
