The invention discloses a swim bladder snorkeling imitating rigid-flexible coupling bionic robotic fish, which relates to the technical field of bionics and comprises an SMA flexible tail fin, an electromagnetic driving pectoral fin, a swim bladder imitating mechanism, an MOS transistor and a power supply. The SMA flexible tail fin is used for realizing tail fin variable stiffness of the bionic robotic fish; the swimming bladder imitating mechanism is used for realizing snorkeling of the bionic robotic fish; the electromagnetic driving pectoral fin is used for realizing straight movement and turning of the bionic robotic fish; the MOS transistor is used as an electronic switch to control the on-off of each branch circuit; the power supply is used for supplying energy to the bionic robotic fish. According to the bionic robotic fish, variable rigidity and flexible swinging of the tail fin of the bionic robotic fish can be effectively achieved, the problem that the SMA wire is slow in cooling is effectively solved, the electromagnetic driving pectoral fin improves maneuverability of the BCF robotic fish and reduces complexity of the mechanism, and compared with a gravity center adjusting mechanism, the swimming bladder snorkeling simulating mechanism has the advantages of being small in size, light in weight and the like. In conclusion, the bionic robotic fish has good movement performance.
