Performance predict model for a body and caudal fin (BCF) biomimetics fish robot

This paper offers a method to model the performance of a BCF (body and/or caudal fin) biomimetic robotic fish. By using a dimensional analysis method, a semi-empirical model for predicting the thrust force generated by a BCF oscillation swimming mode is derived. This model shows good prediction capability, and the predicted results are in good agreement with the experiment data. Therefore, the proposed modeling method can be used to solve the engineering problem concerned without a complex theory derivation.
