Analysis on the Robotic Fish Propulsion for Various Caudal Fin Shapes

In this paper, propulsion characteristic of various shape caudal fin is analyzed. Using added mass theory, some caudal fins for robotic fish propulsion are analyzed. From this analysis, torque and propulsion characteristic for caudal fins with various shapes can be investigated. This method can be adopted to identify the caudal fin performance more simply and faster than computational method, although with less accuracy.
