Robot fish and fishtail working principle thereof

Abstract

The invention provides a robot fish and a fishtail working principle thereof, and relates to the field of mechanical fish. The robot fish comprises a fish main body and a fishtail, wherein the fishtail comprises a plurality of first frame bodies which are hinged sequentially to form a fishtail main body; one end of the fishtail main body is hinged to a second frame body serving as a tail fin; the other end of the fishtail main body is hinged to a third frame body; a mounting groove is formed in the third frame body; the robot fish further comprises a connecting part; the middle part of the connecting part is hinged to the third frame body; an adjustable eccentric wheel device which allows the third frame body to swing horizontally in the horizontal direction relative to the connecting part is arranged at one end, extending to the mounting groove, of the connecting part, and the other end of the connecting part is connected to the fish main body; a driver for driving the adjustable eccentric wheel device is arranged in the fish main body. The robot fish has the benefits that complete fishtail-type swinging of the fishtail can be realized, the robot fish can swim freely in water, and swimming of the robot fish can be more real.

Description

technical field [0001] The invention relates to the field of mechanical fish, in particular to a bionic fish and the working principle of its fish tail. Background technique [0002] A bionic fish is a fish-like machine that can swim in water. Typically the bionic fish is used to spot pollutants and create a real-time 3D map of the harbor, showing what chemicals are currently in the seawater and where they are located. The use of bionic fish can increase the flexibility and adaptability of port authorities to monitor ship pollution, other types of harmful pollutants, and pollutants discharged from underwater pipelines. In addition to benefiting surveillance operations in EU ports, this project could lead to important advances in robotics, underwater communications and robotic intelligence. Existing bionics are divided into three parts: head (including fish fins), body, and tail; the body is the main part of the fish, and the control circuit, motor and related drive circuit...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a working principle of a bionic fish and its tail, so as to solve the problem of poor flexibility of the bionic fish due to the lack of power provided by the swing of the fish tail in the existing bionic fish and the inability to accurately control the swinging action
