Inspired by the way manta rays swim, scientists at North Carolina State University, USA, have created soft robots that are capable of swimming at a speed that is approximately four times faster than the speed of similar robots developed previously. Known as ‘butterfly bots’, these robots weigh around 2.8 grams and possess a soft, silicone body with a pair of bistable flappable wings. Pressurised air helps the wings of the robot move, allowing the butterfly bot to swim fast.
