The debut of a robotic stingray, powered by light-activated rat cells
Researchers have created a robotic mimic of a stingray that’s powered and guided by light-sensitive rat heart cells. The work exhibits a new method for building bio-inspired robots by means of tissue engineering. Batoid fish, which include stingrays, are distinguished by their flat bodies and long, wing-like fins that extend from their heads. These fins move in energy-efficient waves that emulate from the front of the fin to the...
