Motorless Self-Propelled Robots

Engineers at Caltech and ETH Zurich have developed robots capable of self-propulsion without using any motors, servos, or power supply. Instead, these first-of-their-kind devices paddle through water as the material they are constructed from deforms with temperature changes. The work blurs the boundary between materials and robots. In the self-propelled devices, the material itself makes Read more about Motorless Self-Propelled Robots[…]
