A bionic fish movement mechanism

Abstract

The invention belongs to the technical field of bionic robots and particularly relates to a bionic fish movement mechanism. The bionic fish movement mechanism aims at achieving the technical purposes of being flexible in movement, simple in structure and wide in application. To achieve the technical purposes, the bionic fish movement mechanism comprises a bionic fish head, a bionic fish body, a bionic fish tail, bionic fish fins, a fixing plate, a first sliding rail, first sliding blocks, a rack, supporting rods, a first fixed pulley, a first pull wire, a second fixed pulley, a second pull wire, a fixing rod, a first swing rod, a sector gear, a second sliding rail, a second sliding block, a connecting rod, first winding wheels, large belt wheels, cylindrical gears, small belt wheels, flat belts, motors, second winding wheels, a third sliding rail, a third sliding block, first connecting rods, rotating discs, second connecting rods, sliding shafts, second swing rods and baffles. The bionic fish movement mechanism has the advantages of being flexible in movement, simple in structure and wide in application.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, in particular to a bionic fish motion mechanism. 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. The Massachusetts Institute of Technology developed a 1.2-meter-long bionic tuna and a 0.8-meter-long bionic barracuda based on the proposed "jet propulsion theory" of fish tail propulsion. 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 New Me...
