A robot designed to work like a roach
Researchers at UC Berkeley have developed a tiny robot that can withstand a serious beating. Inspired by the cockroach, the postage stamp-sized bot is made of a material called polyvinylidene fluoride, which is able to expand and contract when electric currents are applied to it. This ability allows the robot to survive beneath 132 pounds of weight. It’s fast too, traveling as much as 20 body lengths per second. Such abilities could prove critical during search and rescue operations in the aftermath of a disaster.
