Self Propelling Motorless Soft Robot
California Institute of Technology Engineers have developed a soft robot that is capable of self propulsion without any motor or power. Instead, the robot is able to move through water using material deformation. This occurs when the material it is composed of changes shape due to variances in temperature. The material itself, is a flexible polymer that curls in cold temperatures and stretches out in warm ones. The polymer is positioned to activate a switch inside the robot that is attached to a paddle. When activated, the paddle will move forward, like an oar on rowboat.
