摘      要：The cow-nosed ray is studied as natural sample of a flapping-foil robotic *** structure, motion discipline, and dynamicfoil deformation of cow-nosed ray are *** on the analysis results, a robotic fish imitating cow-nosed ray,named Robo-ray Ⅱ, mainly composed of soft body, flexible ribs and pneumatic artificial muscles, is *** andswimming morphology of the robotic prototype are as that of a normal cow-nosed ray in *** propulsion parameters ofRobo-ray Ⅱ at normal conditions, including the St Number at linear swimming, thrust coefficient at towing are studied *** suitable driving parameters are confirmed considering the efficiency and swimming *** of 0.16 m·s’and thrust coefficient of 0.56 in maximum are achieved in experiments.
