Fire-fighting robot with modularized structure

The fire-fighting robot comprises a base arranged on the lower portion, and a front cover and a rear cover are hinged to the head end and the tail end of the base in the length direction respectively. The base, the front cover and the rear cover are all of a thin-wall cavity structure. By the adoption of the fire-fighting robot, the fire-fighting robot is divided into the base with the thin-wall cavity, the front cover and the rear cover, elements can be installed in the cavity structure, and due to the fact that the front cover and the rear cover are hinged to the base, the front cover and the rear cover can turn over along the head end and the tail end of the base; when the fire-fighting robot needs to be disassembled and overhauled, only the front cover and the rear cover need to be turned over, and then the next operation is carried out to expose internal elements of the robot; according to the modularly-arranged fire-fighting robot, elements installed in the base, the front cover and the rear cover are e
