Cockroach-inspired robot

Resilient cockroach-inspired robot survives large falls, dashes off

IEEE Spectrum writes of a small resilient robot created by Paul Birkmeyer and Prof. Ronald Fearing at the Biomimetic Millisystems Lab at UC Berkeley.

Aptly called DASH (Dynamic Autonomous Sprawled Hexapod), the six-legged insect-inspired robot can reach speeds of 1.5 meters per second and is flexible/strong enough to be dropped from a height of 28 meters without breaking. A single DC motor powers the legs and a small servomotor to slightly deform the robot’s body, allowing it to make turns.
