The blade designed by the invention provides a new design thought for a traditional blade noise reduction method. According to the IPMC-driven small robotic fish, the characteristic that an IPMC driving material can generate large deformation after being electrified in water is utilized, the IPMC driving material is applied to tail fin propelling of the robotic fish, and high-efficiency propelling of the small robotic fish in the water is achieved; the deformation degree of the IPMC is changed by changing the frequency of the electric signal, so that the underwater advancing speed of the robotic fish is controlled; and the mechanical structure is simple, different from traditional mechanical driving, the weight is very light, power consumption is low, and noise pollution is avoided. According to the invention, a new idea is provided for the research of the bionic robotic fish, and deeper research is made for the unmanned underwater vehicle.
