AI Technical Summary

Technical Problem

Existing technologies cannot achieve all-terrain adaptive obstacle crossing. In particular, wheeled robots have low movement efficiency in ground mode and cannot be directly transferred to transportation equipment such as flying cars. Furthermore, existing solutions have limited adjustment in height and lateral movement, making them unable to adapt to complex terrain.

Method used

It adopts an integrated wheel-wing design and push-pull rod, combined with sensor group, computing unit and motor drive, to achieve seamless switching of chassis form and structural sharing. By adjusting chassis height, wheel tilt angle and distance, it can adapt to different terrains and switch motion modes to achieve all-terrain obstacle crossing.

Benefits of technology

It improves the obstacle-crossing flexibility and passability of the transport equipment, has a high degree of structural reusability, good lightweight effect, low cost, and adaptability to various terrains.
