AI Technical Summary
When existing tracked robot chassis climb stairs, manual adjustment of the auxiliary support angle is required, resulting in insufficient stability and applicability, especially in maintaining longitudinal stability and operational reliability in different stair environments.
It adopts a ball screw slide assembly and guide rail slider structure, combined with sensors and control system, to automatically adjust the position of the load module and compensate for the center of gravity offset in real time, ensuring the balance of the chassis during the climbing process.
It achieves automatic leveling without manual intervention, improving the stability and applicability of the chassis when climbing stairs, enhancing operational efficiency and reliability, and avoiding the problem of narrow environment applicability caused by excessively wide auxiliary support structures.
