Automaton

technology Maturity 9-11 Next article →

An automaton is a self-operating machine or control mechanism. It is designed to follow a specific sequence of operations. It can also respond to predetermined instructions. Some automata create an illusion of life. For example, bellstrikers in mechanical clocks appear to act under their own will. This makes them look like mechanical robots to a casual observer. Many automata are built to resemble humans or animals. These are often made to entertain or impress people.

Modern versions of these machines are called animatronics. Animatronics use electronics to move. They are frequently used to portray characters or creatures in films. You might also find them in theme park attractions. The term automaton comes from a Latinized Greek word. This word means "acting of one's own will."

There are many ways to power these machines. In the Hellenistic world, inventors used water-powered systems. Ktesibios was a Greek inventor and the first head of the Great Library of Alexandria. He used water to make a model owl move. He also used water to sound a whistle. He is credited with inventing the world's first cuckoo clock.

Other inventors used hydraulics, pneumatics, and mechanics. Hero of Alexandria wrote about these principles in his books. He described siphons, fire engines, and water organs. He even described a programmable cart.

Mechanical complexity can be achieved through various parts. Al-Jazari was a famous inventor who described programmable machines in 1206. He designed a boat with four automatic musicians. This boat floated on a lake to entertain guests. His mechanism used a programmable drum machine. This machine used pegs, also known as cams. These pegs bump into small levers to operate percussion. By moving the pegs, the drummer could play different rhythms.

Al-Jazari also used floats to control movement. A float is a part that rises when water fills a space. He created a "peacock fountain" that used this method. When a user pulls a plug, water flows from the peacock's beak. As the dirty water fills a hollow base, a float rises. This rising float activates a linkage. This linkage makes a servant figure appear from behind a door. The figure then offers soap or a towel.

History shows that different cultures developed these machines. In ancient China, the Lie Zi text mentions an engineer named Yan Shi. Around 400 BCE, he showed King Mu of Zhou a life-size mechanical human. Other Chinese texts describe flying wooden birds made by Mozi and Lu Ban. In the 11th century, the Chinese inventor Su Song built a water clock tower. This tower featured mechanical figurines that chimed the hours.

In the Middle Ages, the tradition continued in the Byzantine Empire. In 949, an ambassador described singing birds and moving lions in a palace. In the 8th century, wind-powered automata were built in Baghdad. These were statues that turned with the wind over palace domes. The Muslim alchemist Jābir ibn Hayyān also wrote recipes for artificial animals. These included snakes and scorpions that could be controlled.

Automata connect to many different fields of study. They relate to mechanical engineering, mathematics, and physics. The Antikythera mechanism is a vital example. It is the earliest known analog computer. It used complex clockwork to calculate the positions of astronomical objects. This device shows how gears can be used to model the heavens.
