Flexible fin wave propulsion amphibious bionic robot

Abstract

The invention discloses a flexible-fin undulating propulsion type amphibious bionic robot, which comprises a body, and flexible fins are symmetrically installed on both sides of the body; the body includes a flexible shell and a frame; the frame is located inside the body; The steering module is used to control the up and down swing of the flexible fins on both sides on the normal phase plane; multiple groups of fin drive modules are installed symmetrically on both sides of the frame to output wave propulsion; the flexible fins on each side are wave-shaped, and the It is used as a flexible drive device for a bionic amphibious robot propelled by flexible fins. The flexible fin undulating propulsion type amphibious bionic robot of the present invention has simple structure, easy maintenance, high energy utilization rate, fast and stable movement, self-locking ability, low noise during operation, strong carrying capacity, amphibious operation ability, and flexible fins on each side. The principle of the motion process is the same, and it can be mass-produced in a modular manner. If a fault occurs, only the faulty part needs to be replaced, which is easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of amphibious robots, and relates to an amphibious robot that operates stably in an amphibious environment, in particular to a flexible-fin wave-propelled amphibious bionic robot. Background technique [0002] The ocean is a strategic development base for energy, biological resources and metal resources, and is currently the most realistic space with the greatest development potential. Underwater robots have been born since the second half of the 20th century, and are designed to perform various tasks in areas that are difficult to reach with ordinary diving techniques. Most of the existing underwater robots are more like a miniature submarine in appearance, and they are all aimed at underwater operations in the deep sea environment. The applied robot is especially helpless to extremely shallow water and the breaking wave zone. The amphibious robot is a special mobile robot that integrates specific movemen...

Problems solved by technology

The problem in this patent is: the movement of the robot is realized on the shore by simple reciprocating motion of four metal sheets, the stability of which is poor during the movement process, and it is prone to dumping; all the power sources of the robot come from 11 steering gears, and the carrying capacity is poor , and the structure is complex

(2) The Chinese patent with the patent application number CN201710155344.3 realizes the rapid floating and diving of the robot in the water through the design of the wheel and paddle steering mechanism. The system is very easy to get entangled with aquatic organisms, and the problem of severe bumps and unstable movements during the movement has not yet been solved
