Mantabot

A ray-inspired underwater vehicle that replicates nature to increase overall efficiency and propulsion levels. This bio-inspired autonomous underwater vehicle (AUV) has been developed as a scientific platform to understand the superior swimming characteristics of batoid fish such as manta rays. ​The MantaBot consists of two parts: a rigid body rendered from a computer tomography scanning image of a cownose ray and a pair of soft fins driven by tensegrity-based actuators. The soft fins of this vehicle are highly flexible, have complex planforms, and undergo an oscillatory motion.
