The invention relates to the technical field of underwater robots, and discloses a bionic robotic fish, comprising: a wire-driven fishtail mechanism comprising a fishtail-imitating structure and a stay wire, the stay wire is connected with the fishtail-imitating structure, the stay wire is connected to a wire connector, and the wire connector is used for pulling the stay wire back and forth by swinging to realize the swinging of the fishtail-imitating structure; the driving mechanism comprises a motor, the motor is connected to the shell assembly, an output shaft of the motor is connected with the transmission mechanism, the transmission mechanism is connected with the wire connector, and the transmission mechanism is used for converting rotation of the output shaft into swing so as to drive the wire connector to swing. According to the bionic robotic fish, circumferential rotation of the output shaft of the motor is converted into swing through the transmission mechanism, the swing output by the transmission mechanism is further transmitted to the fishtail through the pull wire, fish-imitating swing of the fishtail-imitating structure is achieved, the performance of the motor can be released, and high-frequency movement of the line-driven robotic fish can be achieved easily.
