Embodiment 2

[0042] Such as Figure 2a , Figure 2b and Figure 2c As shown, the sleeve 17 is a lifting sleeve arranged on the upper surface of the fuselage frame 1, the outer surface of the lifting sleeve is provided with a rack, and the fuselage frame 1 is provided with a connecting tensioning sleeve. The driving gear 18 of the motor 19, the driving gear 18 meshes with the rack of the lifting sleeve and drives the lifting sleeve to go up and down.

[0043] image 3 Shown is a schematic view of the second embodiment of the adhesive running gear traveling on a flat surface. The robot body outputs rotation and translation motions in the x-y plane to the adhesive walking mechanism by controlling the lateral slider 2; the robot body first outputs rotational motion so that the line connecting the main and follower wheels of the adhesive walking mechanism and the wall forms a certain angle α (position posture angle). The DC motor 3 rotates to drive the adhesion mechanism and the body to ad...

Abstract

The invention discloses a bionic crawler-type adhesion walking mechanism and a moving method thereof. The bionic crawler-type adhesion walking mechanism comprises a machine frame, a tensioning mechanism, a driving mechanism and an adhesion belt, wherein the driving mechanism comprises a driving motor, a driving motor gear, a driving wheel and a driven wheel; the driving wheel is connected with one end of the machine frame through a gear shaft; the driven wheel is connected with the other end of the machine frame through a driven wheel shaft; the driving motor gear is driven by the driving motor; the driving motor gear is meshed with the gear shaft; the tensioning mechanism comprises a tensioning wheel frame, a tensioning spring, a miniature force sensor, a tensioning wheel and a sleeve; the tensioning wheel, the driving wheel and the driven wheel are connected through the adhesion belt; the tensioning mechanism further comprises a mechanism connecting device arranged on the machine frame. A certain tangential displacement and a posture angle are outputted by a robot body, so that the adhesion, detachment and pressing of soles are realized and the walking and halting of a robot on a wall are assisted.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a bionic crawler-type adhesion walking mechanism and a motion method thereof, which are mainly used in wall-climbing robots to realize the functions of adhesion, walking, staying and overcoming obstacles on walls with different inclination angles. Background technique [0002] Three-dimensional surface crawling robot has always been a research hotspot in the field of robotics. The use of wall-climbing robots can replace humans to perform tasks on steep walls, such as cleaning the exterior walls of skyscrapers, overhauling oil and gas tanks, and maintaining nuclear facilities. The study found that there are millions of micron-scale setae growing on the surface of the toes of the great gecko, and there are thousands of nano-scale fluff on the top of each seta. The van der Waals force (that is, intermolecular force) between these bristle arrays and the wall provides support for the gia...
