Abstract

Disclosed is a bionic robot fish. The bionic robot fish comprises an upper jaw and a lower jaw. Two fish eye mounting holes are symmetrically formed in the upper jaw, and fish eyes are arranged in the fish eye mounting holes respectively. The bionic robot fish further comprises an eye driving mechanism. The eye driving mechanism comprises an eye driving motor, a crank and rocker mechanism and a parallelogram mechanism, wherein the eye driving motor is mounted on the upper jaw and connected with the parallelogram mechanism through the crank and rocker mechanism, and the parallelogram mechanism is connected with the fish eyes. According to the bionic robot fish, the fish eyes are driven by the eye driving motor, the crank and rocker mechanism and the parallelogram mechanism to rotate, the structure is simple, and the vivid bionic effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, and in particular relates to a bionic robot fish. Background technique [0002] Before the 1990s, the research on fish bionics mainly focused on the theoretical aspects. With the deepening of the research on the propulsion mechanism of fish and the new development of robotics, bionics, electronic technology, material science and control technology, the simulation of fish swimming A new type of underwater robot based on its dynamic mechanism—the bionic robot fish has received widespread attention at home and abroad. According to the proposed "jet propulsion theory" of fish tail propulsion, the United States Institute of Technology developed a 1.2-meter-long bionic tuna and a 0.8-meter-long bionic barracuda. The Marine Science Center of Northeastern University in the United States has developed a wave-propelled robotic eel using shape memory alloys and linkage mechanisms. The University of ...
