NUS-developed MantaDroid which swims faster and operates up to 10 hours

Building a robot is easy. Building a robot with soft, bendable parts is still doable. But building a soft robot “fish” that can swim as well as the real thing: a much trickier task. Now Researchers from the National University of Singapore (NUS) have created an aquatic robot named as  MantaDroid which swims at the speed of twice its body length per second and can operate for up to 10 hours. Manta rays are considered to one of nature's most graceful and efficient swimmers possess a unique propulsion mechanism.


The NUS team has finally designed MantaDroid after two long years of research and multiple experiments which includes over 40 designs. Unlike other flapping-based underwater robots that replicate manta ray's flapping kinematics by using multiple motors to achieve active actuations throughout the fins.

Previously A team of researchers at Zhejiang University in China has created a small, soft-bodied robot able to swim twice as fast as others of its kind.

 In their paper published in the journal Science Advances, the team describes how they came up with a unique way to power the robot, how well it works, and likely applications for it.
