Robot caterpillar demonstrates new approach to locomotion

Zhu caterpillar 1500 HEADERResearchers at North Carolina State University have demonstrated a caterpillar-like soft robot that can move forwards, backwards and dip under narrow spaces.

The caterpillar-bot’s movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
