Problems solved by technology

In some terrains, robots based on mecanum wheel chassis need to climb steps and pass through rough terrain. The nature of mecanum wheels makes it impossible for robots with ordinary chassis to meet the requirements. Currently, existing robots or chassis cannot climb steps and through rough terrain

Abstract

An omni-directional damping chassis based on a roller conveyor belt and a Mecanum wheel is characterized by comprising a main body frame, a roller mechanism, a track driving mechanism, a Mecanum wheelindependent suspension wheel set, and the Mecanum wheel independent suspension wheel set is symmetrically installed on both sides of the front end and the rear end of the main body frame; a drum mechanism is arranged at the rear end of the main body frame, and the drum mechanism is symmetrically arranged at the left and right parts of the rear end of the main body frame; a crawler drive mechanismis installed in the middle of the main body frame, and the crawler drive mechanism symmetrically mounts the left and right sides of the middle of the main body frame. A drum support of a drum mechanism, a drum, a plurality of drums are mounted on the drum support in parallel, and the drum support is fixed on the main body frame. The invention has the advantages of enhancing the landing property of the Mecanum wheel of the chassis, being capable of ascending and descending steps, and the like. The invention belongs to the technical field of omni-directional mobile robots.

Description

technical field [0001] The invention belongs to the technical field of omnidirectional mobile robots, and in particular relates to an omnidirectional cushioning chassis based on roller conveyor belts and mecanum wheels. Background technique [0002] Mecanum wheels have been widely used in omnidirectional mobile robots due to their flexibility and diversity of motion. The omnidirectional mobile robot based on the mecanum wheel can realize the movement modes of forward movement, lateral movement, oblique movement, rotation and combination thereof, but only when the mecanum wheel is in uniform contact with the ground can the robot run smoothly according to the predetermined trajectory . But in the actual road conditions, due to the unevenness of the ground, the ground force of the mecanum wheels is uneven, and the ground performance is poor, so that the friction force received by each mecanum wheel is uneven during operation, it is easy to slip, it is difficult to Ensure that...
