Audio-Animatronics (also known as simply Animatronics, and sometimes shortened to AAs) is the registered trademark for a form of robotics animation created by Walt Disney Imagineering for shows and attractions at Disney theme parks, and subsequently expanded on and used by other companies. The robots move and make noise (generally a recorded speech or song), but are usually fixed to whatever supports them. They can sit and stand but usually cannot walk. An Audio-Animatronic is different from an android-type robot in that it uses prerecorded movements and sounds, rather than responding to external stimuli. In 2009, Disney debuted an interactive version of the technology called Autonomatronics, and in 2018, announced aerial stunt figures called Stuntronics.
