Audio-Animatronics
Audio-Animatronics (also known simply as AAs) are a form of mechatronic animatronics puppetry created by Walt Disney Imagineering and trademarked by the Walt Disney Company for use in designed shows and attractions at Disney theme parks. Audio-Animatronics move and often synchronize with an audio soundtrack from an external sound system (generally a recorded speech or song), and are usually fixed to whatever supports them.
