Automaton

An automaton (ɔːˈtɒmətən; : automata or automatons) is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions. Some automata, such as bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power or will, like a mechanical robot. The term has long been commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people. Animatronics are a modern type of automata with electronics, often used for the portrayal of characters in films and in theme park attractions. The word "automaton" is the latinization of the Ancient Greek αὐτόματον, automaton, (neuter) "acting of one's own will". This word was first used by Homer to describe an automatic door opening, or automatic movement of wheeled tripods. It is more often used to describe non-electronic moving machines, especially those that have been made to resemble human or animal actions, such as the jacks on old public striking clocks, or the cuckoo and any other animated figures on a cuckoo clock. In ancient Egyptian legends, statues of divinities, mostly made of stone, metal or wood, were animated and played a key role in religious ceremonies. They were believed to have a soul (a kꜣ), derived from the divinity they represented. In the New Kingdom of Egypt, from the 16th century BC until the 11th century BC, ancient Egyptians would frequently consult these statues for advice. The statues would reply with a movement of the head. According to Egyptian lore, pharaoh Hatshepsut dispatched her squadron to the "Land of Incense" after consulting with the statue of Amun. There are many examples of automata in Greek mythology: Hephaestus created automata for his workshop; Talos was an artificial man of bronze; King Alkinous of the Phaiakians employed gold and silver watchdogs. According to Aristotle, Daedalus used quicksilver to make his wooden statue of Aphrodite move.
