Single-joint robot fish and underwater propulsion platform

Abstract

The invention relates to a single-joint robot fish and an underwater propulsion platform, and relates to an underwater propulsion device, aiming at providing a single-joint robot fish and an underwater propulsion platform which are simple in structure, low in cost and simple and convenient to operate. The single-joint robot fish comprises an outer shell, a bionic propulsion mechanism, a power energy module, a control communication module and a posture adjusting mechanism, wherein the bionic propulsion mechanism comprises a tail fin, a C-shaped skeleton, an upper main shaft and a lower main shaft; the tail fin is fixedly connected with the rear end of the C-shaped skeleton; the outer ends of the upper main shaft and the lower main shaft are fixedly connected with two ends of the C-shaped skeleton respectively; the power energy module comprises a battery and a propulsion driving device; the output end of the propulsion driving device is connected with the inner ends of the upper main shaft and the lower main shaft; the control communication module comprises an integrated main control board and an antenna; the posture adjusting mechanism comprises a circumferential rotation driving device and a circumferential rotation counter weight which are arranged in the outer shell; the circumferential rotation driving device is used for driving the circumferential rotation counter weight to rotate around the axis of the outer shell in front-rear direction.

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.
