Genetically Engineered Rat Cells Make This Robot Stingray Swim

This fully controllable robotic ray is powered by a gold skeleton and light-activated cells Robots have advanced an enormous amount over the past few years, but they’re nowhere close to the efficiency and capability of animals. One way to avoid playing catch-up is to simply steal everything you can from animals as directly as possible. Which is exactly what a team of researchers, led by Sung-Jin Park and Professor Kevin Kit Parker at the Wyss Institute for Biologically Inspired Engineering at Harvard did.
