Animatronics are mainly used in movie making, but also in theme parks and other forms of entertainment. Its main advantages to CGI and stop motion is that it is not a simulation of reality, but rather physical objects moving in real time in front of the camera. The technology behind animatronics has become more advanced and sophisticated over the years, making the puppets even more realistic and lifelike.
Animatronics for film and television productions are used to perform action on camera in situations where the action involves creatures that do not exist, the action is too risky or costly to use real actors or animals, or the action could never be obtained with a living person or animal. The application of animatronics today includes computer controlled as well as radio and manually controlled devices. The actuation of specific movements can be obtained with electric motors, pneumatic cylinders, hydraulic cylinders and cable driven mechanisms. The type of mechanism employed is dictated by the character parameters, specific movement requirements and the project constraints.
