Androids, from Greek andr- (man, male) and the suffix -oid (in the form/likeness of), are artificial beings, for example robots, built to resemble humans. Androids have been a long standing feature in science fiction literature and films. While mostly designed to take over menial tasks in the place of humans, they may well be used to replace humans or decide they are better suited for the task anyway...
A few examples are:
The Humanoids by Jack Williamson
The Stepford Wives by Ira Levin
Data from Star Trek, Next Generation
