The Smallest Remote-Controlled Walking Robot Ever Built

Engineers at Northwestern University in Evanston, Illinois, invented the world’s smallest remote-controlled walking robot, according to research published in the journal Science Robotics.  It’s so small that it can crawl along the edge of a penny. Made of an elastic shape-memory alloy, the crab-shaped robot includes no hardware or electrical components. The research team hopes that its robotic design could be used in the future to perform tasks in extremely confined spaces.
