Abstract

The invention discloses a robotic fish with power fins and a method for realizing swimming action. The power fins are mainly symmetrically arranged on two sides of the middle of an existing robotic fish and each comprises a power driving mechanism and a power fin wing, wherein the power driving mechanism is arranged in a casing of the robotic fish and comprises a fixed platform, a steering engine support, a power fin steering engine, a hermetic driving device and a connecting mechanism. The power fin steering engines drive rocker rods of the connecting rod mechanisms to swing, and the rocker rods drive the power fin wings to swing, so that high swimming-forward power can be generated for the robotic fish. By skillful mechanical structure, the power fin wings can swing back and forth at different speeds and fin vanes can be opened and closed on the premise of keeping a steering engine constant in steering direction, and thereby the robotic fish can swim forwards, and purposes of high swimming speed and efficiency, low noise and no weed winding are achieved.

Description

technical field [0001] The invention relates to a robot fish. Background technique [0002] A robotic fish, or an underwater robot, is a machine that looks like a fish and works in water. [0003] At present, some robotic fish adopt the shape of the tail fin of fish, and rely on the swing of the fish fin to provide forward power, imitating the swimming action of fish or dolphins. However, due to the flexibility of fish fins and the good control of fish on eddy currents is not easy to be imitated, the efficiency is very low. Therefore, many robotic fish or underwater robots move slowly and have inflexible movements. Some robotic fish or underwater robots use propellers as propulsion devices, which are prone to entanglement in grass and sundries, and make a lot of noise. Therefore, the propulsion device of the robotic fish is a key component that affects the performance of the robotic fish. [0004] With the increase of human underwater exploration and the expansion of aqu...
