A claw-pair-grabbing type caterpillar track wall-climbing robot

Abstract

The invention discloses a claw-pair-grabbing type caterpillar track wall-climbing robot which comprises a robot body. One end of the robot body is provided with a motor, and a sprocket is connected toan output shaft of the motor. The opposite sides of the other end of the robot body are respectively provided with elasticity tails. The robot body is also equipped with a claw-pair-grabbing type caterpillar track mechanism, and the claw-pair-grabbing type caterpillar track mechanism is connected to the sprocket. The robot body has cam-shaped structures on both sides which constitute cam mechanisms with claw foot adhesion mechanisms, and the cam mechanisms drive the claw foot adhesion mechanisms to perform adhesion/releasing motions. According to the invention, a claw-pair-grabbing type caterpillar track is adopted, and the loading capability is improved through a claw-pair-grabbing mode. Meanwhile, the track structure has the advantage of a large adhesion area, and can be crawl on roughceilings.

Description

technical field [0001] The invention belongs to the technical fields of engineering bionics and mechanical design and manufacture, and in particular relates to a claw-to-grab crawler wall-climbing robot. [0002] Background technique: [0003] Wall-climbing robots are special robots that can crawl on vertical walls, and have broad application prospects in disaster search and rescue, military reconnaissance, space detection, bridge detection and other fields. At present, the climbing technology of wall-climbing robots on vertical walls is becoming more and more mature. The adhesion methods include vacuum adsorption, magnetic adsorption, artificial bionic dry adhesion and wet adhesion. However, there are few studies on robots that can crawl on both vertical walls and inverted surfaces using claw-to-grasp adhesion. [0004] Adhesion technology and moving mode are two key technologies of wall-climbing robots. Claws or hook-like mechanisms are ubiquitous in organisms and mainly ...
