Single joint robot fish and underwater propulsion platform

Abstract

The invention relates to a single-joint robotic fish and an underwater propulsion platform, which relates to an underwater propeller. The purpose is to provide a single-joint robotic fish and an underwater propulsion platform with simple structure, low cost and easy operation. The single-joint robotic fish and the underwater propulsion platform of the invention include an outer casing, a bionic propulsion mechanism, a power energy module, a control communication module and an attitude adjustment mechanism, wherein the bionic propulsion mechanism includes a tail fin, a C-shaped skeleton and upper and lower main shafts, and the tail fin is fixedly connected At the rear end of the C-shaped skeleton, the outer ends of the upper and lower main shafts are fixedly connected to the two ends of the C-shaped skeleton respectively; the power energy module includes a battery and a propulsion drive device, and the output end of the propulsion drive device is connected with the inner ends of the upper and lower main shafts. The control communication module includes an integrated main control board and an antenna; the attitude adjustment mechanism includes a circumferential rotation driving device and a circumferential rotation counterweight arranged in the outer casing, and the circumferential rotation driving device is used to drive the circumferential rotation counterweight to revolve around the outer casing. The axis in the front-rear direction of the body rotates.

Description

technical field [0001] The invention relates to a propeller directly acting on water, in particular to a bionic fish underwater robot. Background technique [0002] With the development of human civilization, the land resources that can be mined and utilized are decreasing and exhausted day by day. The ocean area accounts for 71% of the earth's area, and there are rich biological resources and mineral resources in the ocean. The 21st century is the century of the ocean. The pace of human development and utilization of the ocean is gradually accelerating with the development of science and technology. Underwater robots with the functions of marine survey, seabed exploration, marine salvage, submarine pipeline detection, and underwater detection and tracking have become important tools for exploring the ocean, developing the ocean and ocean defense. [0003] The bionic robot fish can carry out long-term, large-scale, and complex underwater operations, and can be used in occa...

AI Technical Summary

Problems solved by technology

[0004] At present, the propulsion and steering of bionic robot fish at home and abroad mainly rely on the cooperation of the two-degree-of-freedom pectoral fin and tail fin to realize the corresponding movements. The structure and control procedures affect the maneuverability of the robot fish, and are not conducive to the popularization and promotion of the bionic robot fish among enthusiasts.
