Cambridge, Massachusetts – Researchers led by George Whitesides, a chemist at Harvard University, have engineered a three-legged silicone device that is powered by combustion, reports Kathleen Sanderson of Nature News.
The soft robot has in each of its legs a channel with a soft valve at its end. Methane and oxygen are fed into the channels in the ratio of one part methane to two parts oxygen. The computer regulating the gases also controls a high-voltage cable connected to electrodes in each leg.
