Bionic robotic fish are a new type of underwater robot with the advantages of high speed, high efficiency, and reductions in energy consumption. To further explore the mechanism used to move these bionic robotic fish, we focus on the present kinematic model and identify defects, e.g., the head sway caused by the manufacturer and inherent fish structure has not yet been considered. Therefore, after considering the head sway of the bionic robotic fish, we establish a head away equation, introduced the sway offset, and revised the kinematic model. Next, we used MATLAB to optimize the model. Our analytic results show that the revised kinematic model more precisely describes the swimming properties of the bionic robotic fish. Finally, we applied our revised kinematic model to experiments involving three-joint bionic robotic fish. Our experimental results show that our model can effectively restrain the head sway of the fish and thereby increase the swimming speed.
