Light-weight and small-sized mangneto swinging bionic robot fish

Abstract

The invention discloses light-weight and small-sized mangneto swinging bionic robot fish, which comprises a fish body, a magnetic motive force fish tail, a U-shaped block and a charging pile, wherein the fish body and the magnetic motive force fish tail are connected through the U-shaped block, the charging pile is arranged at the lower end of the surface, connected with the fish tail, of the fish body, the fish body comprises an infrared sensing probe, a second waterproof casing I, a second waterproof casing II, a control switch and a waterproof soft plug, the second waterproof casing II is arranged at the outer surface of the fish body, and the magnetic motive force fish tail comprises an magnetic induction coil, a rotating shaft, a PVC (polyvinyl chloride) tube pipe, a round permanent magnet and a flexible fish tail. The light-weight and small-sized mangneto swinging bionic robot fish has the advantages that the structure is simple, the weight is light, and the size is small; a magnetic motive force pushing mechanism does not need any waterproof protection, and the complexity of the mechanism is greatly reduced, the energy consumption is low, and the cruising capability is improved; the energy consumption power of a magnetic motive force mode is 1 / 4 of that of a motor, and in addition, the work voltage range is wider; the control is simple and convenient, and the advancing, the acceleration, the turning, the sinking and floating and the like of the robot fish can be easily controlled through controlling the current direction and the current intensity of the coil.

Description

technical field [0001] The invention relates to a bionic robot fish, in particular to a light and small bionic robot fish with magnetic swing. Background technique [0002] The swimming of fish, especially the swimming of trevally, is mainly realized by the fluctuation of the body trunk and the regular unsteady movement of the fins, including starting, cruising, turning, acceleration and deceleration, and ups and downs. Fish swimming has the characteristics of high movement efficiency, low resistance, high mobility, low noise, and little disturbance to the environment. It is these excellent swimming performances that attract more and more researchers to invest in bionic machines. Among the ranks of fish research. By imitating the shape and swimming mechanism of fish, a bionic robotic fish system has been developed to enable it to have efficient and flexible underwater cruising capabilities, which can be applied to resource detection, biological research, and military re...

Problems solved by technology

[0003] At present, most of the bionic robot fish are realized by motor joint cascading or artificial muscle drive, which mainly have the problems of redundant volume, difficulty in waterproofing, and complicated control, especially the waterproofing of the movement mechanism, which will hinder the development of robotic fish. bring great constraints
