|Abstract||This paper presents the mechanical design and control of biomimetic robotic fish with high maneuverability. These robotic fish modelled after Esox lucius adopts multilink propulsive mechanism for high turning speed and small turning radius. According to the different tasks, these robotic fish are designed with decorated pectoral fins for two-dimensional horizon plane, or controllable pectoral fins with multi degrees of freedom for three-dimensional space. Through observing and analyzing the fast-start of natural fish, we separately developed corresponding control strategies for a dynamic trajectory tracking strategy based C-start and an L shape sliding method based S-start. Finally, a four-link robotic fish is able to execute C-start flexibly with a turning angle of up to 213°, a top turning rate of approximately 670 °/s, and an upper limit of turning precision of less than 10° and an S-start with a peak turning rate up to 318.08±9.20°/s. The experimental results verify the effectiveness of our developed robotic prototypes and also control approaches for C-start and S-start.|
