The bio-inspired robot is a made of a mixture of living rat heart cells and artificial material. The development of the robot ray is described in the journal Science on Thursday. “It struck me like a thunderbolt.”Parker and his colleagues created the robot ray out of a gold skeleton in the shape of a stingray, covered with a thin layer of flexible polymer. The result is a swimming robot ray that follows the light source. Scientists have unveiled a miniature robotic stingray the size of a toenail that sails smoothly through water, guided by pulses of light.
