Watch: This hypnotic robotic manta ray glides through water silently | ZDNet Video Description

"Unlike other flapping-based underwater robots that replicate manta ray flapping kinematics by using multiple motors to achieve active actuations throughout the fins, MantaDroid is powered by only one electric motor on each fin," says Associate Professor Chew Chee Meng, who worked on the project. "We then let the passive flexibility of the fins interact naturally with the fluid dynamics of the water to propel the subsequent motions."
