Maneuverability is critical to the performance of autonomous underwater vehicles (AUV) and fast swimming marine animals, which perform rapid turns to catch prey. Major features affecting maneuverability are positions of control surfaces (i.e., flippers, fin, flukes) and flexibility of the body. Position of control surfaces provides a generally stable design with respect to an arrow model. Animals with flexible bodies and mobile control surfaces are able to turn tightly at low turning rates, whereas fast-swimming animals with less flexibility and relatively immobile control surfaces sacrifice small turn radii for higher turning rates. Powered and unpowered turns were executed by body flexion in conjunction with use of control surfaces. Banking is used in powered turns and in unpowered turns where major control surfaces were horizontally oriented. Turning radius is dependent on body size and swimming velocity. Information gathered from the design and kinematics of aquatic animals has been incorporated in the development of biomimetic AUVs. The bio-inspired MantaBot displays enhanced maneuvering performance compared to conventional AUVs.
