An Android is a robot with the appearance of a human. They are sometimes referred to as automatons or mechanical dolls. Robots in general (not necessarily in the form of humans) have many uses. In the armed forces they are used to aid in detonating bombs thereby saving human risk and in the military as remote controlled devices- whether to provide unmanned aircraft for reconnaisance work or for air to ground missiles. Robotics are also used in many areas of manufacturing such as in the car industry. Robots also feature widely in many science fiction films, but in Japan and Korea they are developing functions in robots that mirror very closely the movements of human beings including facial expressions and complex movements of "joints".
