1.A type of robot used for entertainment, demos, etc, and looks like a real living being also known as Audio-Animatronic in Walt Disney's term.

2.A robot used for shows at Disneyland, Chuck E.Cheese, Showbiz, and other various theme parks and restaurants.

3.What almost killed a guest in a theme park in the movie West World with Yul Brynner.

The combination of Animation and Electronics made to scare the living shit out of people. A good example of an animatronic would be the children's favourite character, Chuck E cheese. Who personally scares the terd right out of me!
