Problems solved by technology

[0003] At present, the bionic robot fish mainly adopts the steering gear drive system, and the steering gear drive system has the disadvantages of large volume and high energy consumption. The current surface and underwater vehicles mostly use traditional propellers as propellers, which are large in size, heavy in weight, and energy-consuming. High, and the current bionic robot fish can't realize the natural swing of the fish well

Abstract

The invention discloses a magnetic-driven mechanical fish. The mechanical fish comprises a fish body, a connecting shaft, a plurality of fish body driving mechanisms, a plurality of fish tail guidingmechanisms and a plurality of fluctuating scales; the fish body comprises a main fish body and a fish tail, the connecting shaft is longitudinally arranged in the fish body, one end of the connectingshaft is connected with the front end of the main fish body, and the other end of the connecting shaft is connected with the rear end of the fish tail; the fish body driving mechanisms are arranged inthe main fish body and mounted on the connecting shaft and adopt magnetic power. The fish tail guiding mechanisms are arranged on the fish tail and mounted on the connecting shaft. The mechanical fish adopts the idea of large degrees of freedom and calculus, each fish body driving mechanism controls local swinging of a certain part of the main fish body, magnetic drive is utilized to control local swinging of the main fish body, and when the driving mechanisms are sufficient, natural swinging of the mechanical fish is finally realized.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, and in particular relates to a magnetically driven robotic fish. Background technique [0002] The bionic robot fish is carried out by imitating the movements of fish in nature, by simulating the advance and change of direction of fish. The fish uses the alternate contraction of the trunk and tail muscles to twist the body left and right to hit the water flow. The fish pushes the body forward with the help of the reaction force generated by hitting the water. The tail fin determines the direction of the fish's movement. [0003] At present, the bionic robot fish mainly adopts the steering gear drive system, and the steering gear drive system has the disadvantages of large volume and high energy consumption. The current surface and underwater vehicles mostly use traditional propellers as propellers, which are large in size, heavy in weight, and energy-consuming. High, and the current bionic...
