Chapter 23 — Biomimetic Robots

GoQBot: Insanely fast robot caterpillar

The GoQBot is a soft-bodied silicon rubber robot which uses a ballistic rolling technique powered by actuators made out of shape-memory alloy coils to move "crazy fast"; its push-off time is under 250 ms, and it spins at 300 rpm.
