This DIY Bipedal Robot Used Pneumatic “Air-Muscles” Instead of Motors

A headless, armless bipedal robot called the Shadow Walker was created by a hobbyist group in the late 1980s, using pneumatic "air-muscles" instead of traditional motors. The creators of the Shadow Walker later went on to establish a pioneering robotics company. This DIY project showcased an innovative approach to robotics and highlighted the potential of using pneumatic technology in creating humanoid robots.
