AI Technical Summary

Technical Problem

Existing wheel-legged vehicles are prone to interference with obstacles when climbing high vertical obstacles, resulting in complex control and poor stability. Existing support devices are unstable, making it difficult to achieve efficient obstacle crossing.

Method used

The wheel-leg type obstacle crossing assistance device includes a first drive mechanism, a second drive mechanism, a slewing mechanism, and a rotating support mechanism. Through the active rotation and support of the tracks, it assists the vehicle in overcoming obstacles, reduces the impact on the joint motor, and improves stability.

Benefits of technology

It improves the off-road capability and passability of wheel-leg vehicles, enabling them to stably traverse higher obstacles, reducing control difficulty, and decreasing the burden on the joint motors.
