Problems solved by technology

[0003] There are two main mobile modes of wall-climbing robots: leg type and crawler type. The leg type structure is more complicated, requires more drives, and the climbing stability is not good. The crawler type requires a smooth wall surface.

Abstract

The invention belongs to the technical field of machine manufacturing, and particularly relates to a wall-climbing robot with a passive compression structure and biomimetic claws. The wall-climbing robot comprises an upper machine body plate, a lower machine body plate, a crank block, the claws and a tail. The upper machine body plate and the lower machine body plate are respectively connected with at least three claws, wherein the claws are symmetrically distributed left and right, and all the claws are connected with the upper machine body plate and the lower machine plate body through elastic leaf springs. The elastic leaf springs deform directionally to provide pre-compression for the claws in a passive mode. According to the wall-climbing robot, the structural design of the one-way elastic claws is adopted, and the claws have the characteristics of being capable of sliding and fixedly clawing and adhering when the wall-climbing robot moves. When the claws slide upward along a wall face along with a machine body, the claws cock backward, and therefore the resistance of upward movement is reduced; when the claws claw and adhere to a wall, the claws are fixed in position due to structural limit, and therefore clawing and adhering are firmer. In addition, the wall-climbing robot is simple in structure, convenient to operate and use, low in manufacturing cost, and suitable for being popularized and applied in related technical fields.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, in particular to a wall-climbing robot with a passive compression structure and bionic claws. Background technique [0002] Wall-climbing robots are of great significance for military reconnaissance and rescue in extreme environments. In order to realize the crawling function, the wall-climbing robot must have two basic functions of adsorption and movement. Generally, wall-climbing robots use negative pressure adsorption and magnetic adsorption, as well as bionic nano-adhesion materials that have developed rapidly in recent years. Among them, negative pressure adsorption requires a smooth and flat wall surface, and magnetic adsorption requires a ferromagnetic wall surface, while biomimetic nano-adhesion materials are difficult to manufacture and have poor adhesion to rough wall surfaces. Therefore, all three adsorption methods have limitations. [0003] There are two main movi...
