- Abstract:
-
To address the sudden and diverse obstacles on unstructured roads in open-pit mines, which greatly affect the path planning and safe operation of unmanned trucks, a path-planning algorithm based on improved timed elastic bands (TEB) is proposed. This algorithm streamlines the number of truck pose calculations and minimizes path-turning amplitude by adjusting and fusing pose trajectory points. It also introduces a buffer layer between the obstacle expansion layer and the safe driving area to achieve optimal safe path planning in the static cost map, preventing local optimization in complex environments. Experimental results show that, when dealing with static obstacles, the proposed algorithm significantly improves the ability to safely navigate around obstacles compared with the traditional TEB algorithm. Furthermore, it increases the average navigation speed, effectively ensuring the safe and efficient transportation of unmanned trucks in open-pit mines.
