bionic robot fish

Abstract

The invention discloses a bionic robotic fish which comprises a fish head and a fish body connected with the fish head. The fish body comprises a trunk skeleton connected with the fish head, a tail skeleton connected with the trunk skeleton and fins arranged on the trunk skeleton, wherein the fins include fin skeletons and fin supports connected with the fin skeletons, the fin supports are connected with the fish body, and the fin skeletons include skeleton base plates and multiple mutually hinged flexible joints arranged on the skeleton base plates. The bionic robotic fish is simple in fin structure and has a vivid bionic effect.

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 ...
