Wheeled handling robot capable of climbing steps

Abstract

The invention discloses a wheeled handling robot capable of climbing steps, relates to the technical field of obstacle-crossing robots, and solves the technical problem that the existing wheeled handling robot has a relatively complex structure and the material box is easy to slip when climbing steps, and the main points of the technical scheme The front lifting auxiliary structure and the rear lifting auxiliary structure are added to realize the fast climbing action for terrain such as steps; the self-balancing structure keeps the material box loaded in it horizontal by gravity to prevent the material box from tipping over, and the assembly The two sets of rollers are connected by tension springs to ensure the stability of the self-balancing structure and the overall structure; the linkage mechanism between the self-balancing structure and the front lifting auxiliary structure is designed to further ensure that the material loaded on the chassis climbs the steps. box level.

Description

technical field [0001] The present disclosure relates to the technical field of obstacle-surmounting robots, in particular to a wheeled transport robot capable of climbing steps. Background technique [0002] Robots are mechanical devices that can work autonomously. With the development of society and economy and the advancement of science and technology, many dangerous or repetitive jobs are gradually replaced by robots. In the logistics handling industry, robots are often used for transportation, picking up goods and other operations. [0003] Some mobile robots that have been developed include wheeled, tracked, legged and other mobile robots. The chassis structure of some robots is relatively superior and can be applied to complex terrain environments. Among them, the planetary wheel chassis has a large structure and high load-to-weight ratio; the crawler chassis has a large supporting area, strong terrain adaptability, and stable movement; the leg chassis has flexible ...

AI Technical Summary

Problems solved by technology

However, for non-planar terrain such as step structures, the chassis structure and control system of the above-mentioned robots are too complicated

And for the transportation of scattered items loaded in the material box, at present, when all kinds of obstacle-climbing robots climb the steps, there is a risk that the material box will tilt and cause the item to slip or multiple stacked material boxes will fall due to tilting and sliding.
