Intelligent bionic robotic fish

The invention relates to the technical field of bionics, and discloses an intelligent bionic robotic fish which comprises a head part, a fish body part and a tail part which are sequentially connected, the tail part comprises a plurality of tail fin blocks which are sequentially connected in a clamped mode, and a plurality of elastic pieces are connected between every two adjacent tail fin blocks; a driving mechanism is arranged between the fish body part and the tail part, the driving mechanism is connected with a pull wire, the pull wire sequentially penetrates through the multiple tail fin blocks, and the end, away from the driving mechanism, of the pull wire is connected with the tail fin block farthest from the fish body part. According to the intelligent bionic robotic fish, when the intelligent bionic robotic fish cruises, the driving mechanism drives the pull wire to adjust the clamping tightness degree between the tail fin blocks in the tail according to different cruising states, so that the rigidit
