Robot Theater A collection of robots were arrayed inside a theater, each of which, when highlighted in the theater's video program, lit up and, in several cases, performed movements. Mobile robots included: Shakey, Prototype Mars Rover, the Stanford Cart, the quadruped Titan III from the Tokyo Institute of Technology, and a Denning Mobile Robot; robot arms included Unimate I, the Rancho and Stanford Arms and Orm from Stanford, the Direct Drive Arm-1 from Carnegie Mellon University, and the Tentacle Arm from MIT.
