Abstract

The invention provides a track-deformable robot moving platform for a dangerous hazard site environment. The track-deformable robot moving platform for the dangerous hazard site environment comprisesa robot body, two passive self-adapting track modules and an information acquiring module, wherein each passive self-adaptive track module comprises a track, a passive self-adapting mechanism, four fixing supporting frames, three track driven wheels, four track bearing wheels and a track driving wheel; the fixing supporting frames are inverted Y-shaped frames, and every two fixing supporting frames form a group, and the two fixing supporting frames in each group are leftwards and rightwards symmetrically connected through corresponding connecting shafts; two track bearing wheels are correspondingly fixed to two end parts of Y shapes of the lower parts of the fixing supporting frames in each group through the corresponding connecting shafts; and one track driven wheel is fixed to the upperpart of each of the fixing supporting frames in each group through the corresponding connecting shaft. According to the moving platform, the shape of the tracks can be flexibly passively changed basedon the size of a barrier in the environment, and the contact area between the track and the barrier can be increased, and thus the barrier crossing capacity of the moving platform is improved.

Description

technical field [0001] The invention relates to the technical field of robot mobile platforms, in particular to a crawler deformable robot mobile platform oriented to dangerous and disaster site environments. Background technique [0002] The way the crawler robot contacts the ground is surface contact, which has a large contact area, small grounding specific pressure, and small subsidence on soft or muddy roads. The outer track has grubs, and the ground friction is large, which can generate a large driving force. , so the ability to pass on muddy or soft ground is strong, and the crawler-type mobile mechanism robot has a small turning radius, which can realize in-situ steering. It has excellent performance in overcoming obstacles such as bosses, slopes, continuous steps, and trenches. Overturned. The application research of crawler robots is extensive, and it has both efficiency and obstacle passing performance. Ordinary crawler robots are mostly articulated swing arm stru...
