Frog-imitating underwater detection robot

Abstract

The invention discloses a bionic frog type underwater detection robot, a robot main body comprises a swimming mechanism, a steering mechanism and a floating and sinking mechanism, bionic mechanism design is respectively carried out by simulating the appearance structure of a frog, and the swimming mechanism simulates the four limbs of the frog to swim in water, so that the robot can swim in the water through the water flapping, gliding and restoring actions of the frog; the steering mechanism rotates leftwards and rightwards by imitating the triangular head of the frog and is matched with a steering rudder blade at the tail part of the robot to realize the underwater steering of the robot; the floating and sinking mechanism simulates the principle that the belly of a frog expands and contracts, and buoyancy is changed, so that the robot floats and sinks in water. In addition, the robot is further provided with an electronic frog eye which simulates the frog eye, so that the robot can carry out underwater operation such as target tracking and shooting underwater. And the propeller is arranged at the tail part, so that the underwater maneuverability is enhanced. The bionic frog robot has high similarity by simulating the underwater movement mode of frogs, and has certain significance in bionic mechanism research and underwater robot development.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a mechanism design of an underwater detection robot imitating frog motion. Background technique [0002] Bionic robots are a research hotspot in the field of robotics. By imitating the movement of animals, the robot has high movement efficiency. The existing frog-type bionic robots are mostly driven by software pneumatics, or are driven by a multi-degree-of-freedom linkage mechanism through multiple motors to drive multiple joints of the legs respectively. The structure of the soft legs makes the driving method relatively simple. The legs are straightened by inflation, and the memory flexible mechanism makes the legs recover and contract, but it does not have a high degree of bionics for the legs of the frog; and the rigid link mechanism, Although the leg bones of the frog legs are replaced, the existing linkage mechanisms are mostly multi-degree-of-freedom, which requires multiple...

Problems solved by technology

The structure of the soft legs makes the driving method relatively simple. The legs are straightened by inflation, and the memory flexible mechanism makes the legs recover and shrink, but it does not have a high degree of bionicity for the legs of the frog; while the rigid linkage mechanism, Although the leg bones of the frog legs have been replaced, the existing linkage mechanisms are mostly multi-degree-of-freedom, which requires multiple motors to drive, making the complexity high and the cost high

[0003] In addition to the design of the legs, the existing bionic robots for frogs are not very bionic, most of them only use bionics for the legs, and there are few bionics for the shape and the ups and downs in the water
