Fish-Like Maneuver

Fish flap their tails asymmetrically to maneuver around obstacles. In contrast, classic fishtail models/studies focus on symmetric motions in a uniform flow. We studied the dynamic response of asymmetric flapping motion and corresponding wake structure. Our wireless X-Y plane air bearing system provides a near friction-less condition for hydrofoil maneuver. Fisher-man system automated the test procedure to guarantee the precision of each test trial.

With the precise dynamical response of hydrofoil for corresponding motion input, we are working on a suitable scaling model to provide a way to model the fish like maneuver which could be directly adopted to closed-loop control of high-performance fish robot swimming.
