Animatronics

Animatronics refers to mechatronic puppets. They are a modern variant of the automaton and are often used for the portrayal of characters in films and in theme park attractions.

Before the term "animatronics" became common, they were usually referred to as "robots". Since then, robots have become known as more practical programmable machines that do not necessarily resemble living creatures. Robots (or other artificial beings) designed to convincingly resemble humans are known as "androids".

Animatronics is a multi-disciplinary field which integrates puppetry, anatomy and mechatronics. Animatronic figures can be implemented using both computer control and human control, including teleoperation. Motion actuators are often used to imitate muscle movements and create realistic motions in limbs. Figures are usually covered with body shells and flexible skins made of hard and soft plastic materials and finished with details like colors, hair and feathers and other components to make the figure more lifelike.
