bionic robot fish

Abstract

The invention discloses a bionic robot fish. The bionic robot fish comprises a fish head and a fish body connected with the fish head, wherein the fish body comprises a fish trunk framework, a tail framework and fish fins; each of the fish fins comprises a fish fin framework, a fin bracket connected with the corresponding fish fin framework, a fin swinging device and a fin rotating device; each of the fin swinging devices comprises a fin swinging motor, a fin rotary table and a fin crank; each of the fin swinging motors is arranged in a fin motor box, and the rotating shaft part of each of the fin swinging motors penetrates through the corresponding fin motor box; each of the fin rotary tables is arranged on the rotating shaft part of the corresponding fin swinging motor in a sleeving manner; two ends of each of the fin cranks are separately and pivotally connected with the corresponding fin rotary table and the corresponding fin bracket; each of the fin brackets is pivotally connected with the corresponding fin motor box; each of the fin rotating devices comprises a fin rotating motor and a connecting rod; each of the fin rotating motors is fixedly connected with the corresponding fin bracket; and each of the connecting rods is fixedly connected with the corresponding fish fin framework, and is connected with the rotating shaft part of the corresponding fin rotating motor. According to the bionic robot fish disclosed by the invention, the structure of the fish fin is simple, and the bionic robot fish disclosed by the invention 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 ...
