Underwater high-simulation robotic fish mechanism and system

Abstract

The invention discloses an underwater high-simulation robotic fish mechanism and system. The robotic fish mechanism and system comprise a front shell, a control cabinet, fish skin, a dorsal fin, an anal fin, a power mechanism and a tail swinging mechanism, wherein the power mechanism is positioned in the control cabinet, and comprises a driving motor, a master control circuit, a slave control circuit and a power source; the tail swinging mechanism comprises a crank mechanism, fish bones and a tail fin; the crank mechanism comprises a first bevel gear, a second bevel gear, a bearing pedestal, a magnet and a swing rod; the output end of the power source is electrically connected with the input end of the master control circuit; the output end of the master control circuit is electrically connected with the input end of the driving motor; the slave control circuit is positioned under the crank mechanism and is in communication connection with the master control circuit; the driving motor is fixedly mounted in the control cabinet; a shaft hole is formed in the tail end of the control cabinet. The underwater high-simulation robotic fish mechanism and system disclosed by the invention drive a robotic fish to swim by adopting a single joint, so that the design is artful, and the structure is reasonable.

Description

technical field [0001] The invention belongs to the technical field of underwater bionic robotic fish, and in particular relates to a single-joint underwater high-simulation robotic fish mechanism and system capable of remote control. Background technique [0002] The development of robotic fish reflects the increasing attention paid by humans to the development of marine resources. The research of robotic fish needs to combine various technologies such as bionics, mechanical design, materials science, and control disciplines. Some of the existing robotic fish have complex structures, many joints, and high cost; some only rely on the swing tail mechanism to realize underwater movement, and do not achieve the bionic effect. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a simple structure, single-joint underwater highly simulated robotic fish mechanism and system. [0004] To achieve the above objec...
