Abstract

The invention belongs to the technical field of robots and discloses a multi-mode rigidity and flexibility combined snake-like robot device. The multi-mode rigidity and flexibility combined snake-like robot device comprises a plurality of snake-like robot unit modules which are connected in series, every two adjacent snake-like robot unit modules are connected, and each snake-like robot unit module comprises two frameworks, three motors, a plurality of transmission mechanisms, a plurality of shafts, a plurality of wheels, a plurality of sets of belt wheel mechanisms, a plurality of driven wheels provided with one-way bearings, and the like. The multi-mode rigidity and flexibility combined snake-like robot device can travel in multiple modes, not only can directly move like a multi-section car, but also can rapidly move in the narrow terrain by abutting against the wall and rapidly move in a snake-like mode on the wide ground, and is high in terrain adaptability. The multi-mode rigidity and flexibility combined snake-like robot device has a plurality of degrees of freedom, and is good in flexibility, small in cross section, good in trafficability characteristic, simple in structure and easy to control.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to the structural design of a multi-modal rigid-flexible composite snake-shaped robot device. Background technique [0002] Snake robot is a typical bionic robot, which has the characteristics of high redundancy, small cross-section, and modularization. It can adapt to rough, rugged, and complex terrains, and climb obstacles. It has other advantages in flexibility and functionality. The unique advantages that the kind of robot does not have. [0003] Snake robots can be divided into two categories: passive joint active wheel type and active joint passive wheel type according to the source of moving power. Passive joints and active wheeled snake robots rely entirely on the wheels or crawlers on the side of the device to provide power for movement, and their joints can automatically adapt to changes in the environment and terrain. This kind of snake-shaped robot generally...
