KAIST's BeetleBot uses 3D-printed artificial muscles and is steered by a sensor on the finger

KAIST researchers built BeetleBot, a robot modelled on an African beetle that walks and grips with 3D-printed liquid crystal elastomer muscles that contract about 45% when heated. An operator steers it with a bend sensor worn on a finger while a camera streams its view back. In lab tests it turned, grabbed an object and carried it elsewhere, pointing to inspection of tight spaces.
