Researchers from New York University recently created a jellyfish drone that can imitate the movement of a swimming jellyfish. The drone was designed by Leif Ristroph who is an applied mathematician at NYU. He presented the jellyfish drone at the fluid dynamics conference in Pittsburgh. By using jellyfish as their inspiration the researches set out to accomplish an active stable hovering drone that only uses flapping wings.
Ristroph initially wanted to create a drone based off insect wings; however, he ended up having the wings pointed downward and not sticking out to the side. When the wings started flapping back and forth there was enough power to lift the drone into the air.
We will just have to wait and see other robots Ristroph will come up with next.
