Android

An android is an artificially created being that resembles a human being. The word derives from Greek Android- ‘man, human’ and the suffix -eides used to mean ‘of the species, kind, alike’ (from eidos ‘species’).

The word droid, a robot in the Star Wars universe, is derived from this meaning. Some people maintain that, etymologically, the word android means resembling a male human and that a robot resembling a woman should logically be called a gynoid for sexist language to be avoided; however, this word is not commonly used. Unlike the terms robot (a mechanical being) and cyborg (a being that is partly organic and partly mechanical), the word android has been used in literature and other media to denote several different kinds of man-made, autonomous creations: a robot that closely resembles a human

a cyborg that closely resembles a human

an artificially created, yet primarily organic, being that closely resembles a human

Although essentially human morphology is not the ideal form for working robots, the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra (devices that exhibit likeness) and automata (devices that have independence). The term android was first used by the French author Mathias Villiers de lisle-Adam (1838-1889) in his work Tomorrow’s Eve, featuring a man-made human-like robot named Hadaly. As said by the officer in the story, “In this age of Realien advancement, who knows what goes on in the mind of those responsible for these mechanical dolls.”
