The invention provides a tail fin rapid swing propelling bionic underwater robot system based on a Scotch yoke, relates to the technical field of bionic propelling and underwater robots, and aims at solving the problem that in the prior art, a tail fin propelling structure is low in swing speed. The bionic underwater robot system comprises a main machine shell, a tail fin driving motor, a Scotch yoke mechanism and a tail fin structure, the Scotch yoke mechanism comprises an eccentric shaft, a rocker frame and a connecting shaft, the tail fin driving motor is arranged in the main machine shell, an output shaft of the tail fin driving motor is connected with the eccentric shaft, the head end of the rocker frame is provided with a vertical upward sliding groove, and the tail fin structure is arranged in the connecting shaft. The eccentric shaft is slidably arranged in the sliding groove, the middle section of the rocker frame is provided with a vertical connecting hole and is rotatably connected with the connecting shaft through the connecting hole, the connecting shaft is connected to the tail end of the host shell, and the tail end of the rocker frame extends out of the host shell and is connected with the tail fin structure. The robot simulates swinging of the fish tail, transmission efficiency is high, the response speed is high, high-frequency swinging of the tail fin is achieved, and the swimming speed is increased.
