It looks like a baby manta ray flapping its wings as it glides through the water. But it’s actually an aquatic robot which swims at a speed of twice its body length per second and can operate for up to 10 hours. Meet the MantaDroid.

(From Business Insider / by Sujin Thomas) — It’s the brainchild of a team from the National University of Singapore’s (NUS’) Department of Mechanical Engineering, which set out two years ago to develop a bio-inspired autonomous underwater vehicle (AUV), said a statement on Nov 8.
The MantaDroid measures 35cms in length, 63cms in width and weights 0.7kg, and was created after an in-depth study of fluid dynamics and experiments which included the testing of 40 different fin designs.

The fins that eventually made the cut, are a pair of flexible pectorial fins made out of PVC sheets and have showed positive results in pool trials in terms of manoeuvrability and swimming capability.

Each fin is powered by a sole electric motor, unlike other similar flapping-based AUVs.
