AI Technical Summary

Technical Problem

In open-pit mining operations, existing technologies struggle to balance real-time performance and accuracy in the bucket and walking mechanism of intelligent loading robots and collision detection methods for mining trucks. In particular, the accuracy in approximating irregular geometric shapes is insufficient, affecting the feasibility of trajectory planning.

Method used

The mining truck and its traveling mechanism are simplified into a cuboid model, and the bucket is simplified into a cylindrical model. Collision detection is performed based on the separation axis theorem. By constructing the separation axis and calculating the projection interval, it is determined whether there is overlap, thus achieving fast and reliable collision detection.

Benefits of technology

It improves the computational efficiency of collision detection, ensures the safety and reliability of the bucket trajectory, and guarantees the safe operation of the intelligent loading robot.
