ABSTRACT:  

It is well accepted that flapping is much more efficient than traditional propellers. That’s the reason why fish and birds adopt flapping as the way of motion. However, current robot flapping propulsors are mostly rigid and far unlike their nature counterparts. Several flapping propellers are designed using the wire-driven mechanism, and they are utilized as the robot fish caudal fin. With single section wire-driven tail, the robot fish could move in oscillatory form; with multiple section wire-driven tail, undulatory form swimming is achieved. Experiments show that the prototype is able to swim forward and turning to both sides. The forward speed is around 0.413 BL/s, and the turning radius is around 0.12BL. The Froude efficiency of this robot fish is 62.4% when the flapping amplitude is 45º, and the frequency is 0.75Hz.
