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. ... Animatronic figures can be implemented with both computer and human control, including teleoperation.
Structure - Frame or skeleton
An animatronics character is built around an internal supporting frame, usually made of steel. Attached to these "bones" are the "muscles" which can be manufactured using elastic netting composed of styrene beads.
Emotion Modeling
Dimensional models of emotion suggest that a common and interconnected neurophysiological system is responsible for all affective states. These models contrast theories of basic emotion, which propose that different emotions arise from separate neural systems.
Exterior or Skin Latex
Foam latex is a lightweight, soft form of latex which is used in masks and facial prosthetics to change a person's outward appearance, and in animatronics to create a realistic "skin".
