Researchers Create a #Robot Stingray with Light-Activated Living Cells

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard have utilized living heart cells of a rat to power a robotic ray. The research, led by Sung-Jin Park and Professor Kevin Kit Parker at Harvard, has led to a robotic ray which relies on contraction of the rat cells to copy the undulating movement of a stingray’s fins. The robot is one-tenth the size of a real stingray. Stingrays have a highly stable and efficient method of swimming. With the undulating movement of the fins, stingrays produce a travelling wave from the front to back of their body. This leads to a force which propels them forward in the water. Because of this, stingrays were also examined to design more efficient submersibles a few years ago. The robotic ray is almost one-tenth the size of a real-life fish.
