Frog bionic swimming robot based on dielectric elastomer telescopic driver

The utility model discloses a frog bionic swimming robot based on a dielectric elastomer telescopic driver, which belongs to the technical field of dielectric elastomers and soft robots and comprises a shell, a storage disc, a dielectric elastomer telescopic belt, a flipper, a controller and a power supply unit. The storage disc is arranged in the shell; the number of the dielectric elastomer telescopic belts is two, one ends of the two dielectric elastomer telescopic belts are fixedly arranged in the storage disc, and the tail ends of the two dielectric elastomer telescopic belts penetrate through the shell channel and symmetrically extend outwards; the flippers are respectively connected to the tail ends of the dielectric elastomer expansion bands; the power supply unit is electrically connected to the dielectric elastomer expansion band; and the controller is electrically connected to the power supply unit. According to the bionic swimming robot, the power supply is controlled by the controller to periodic
