摘要:

本文探讨了移动障碍物之间的导航(NAMO)的问题,并提出了联合路径和推动规划:采取哪条路径和在什么方向的障碍物应该被推,给定一个开始和目标位置。提出了一种路径和障碍物选择的规划算法,采用基于快速探索随机树(RRT)的启发式算法计算最小碰撞路径,当需要施加推力使障碍物滑出时,规划者通过动态物理仿真的手段-目的分析来确定线性推动的顺序,以清除所需的空间。仿真实验表明,我们的方法发现解决方案在更高的杂波百分比(高达49%)相比,直线推计划(37%)和RRT没有推(18%)。

英文摘要:

This paper explores the Navigation Among Movable Obstacles (NAMO) problem and proposes joint path and push planning: which path to take and in what direction the obstacles should be pushed at, given a start and goal position. We present a planning algorithm for selecting a path and the obstacles to be pushed, where a Rapidly-exploring Random Tree (RRT)-based heuristic is employed to calculate a minimal collision path. When it is necessary to apply a pushing force to slide an obstacle out of the way, the planners leverage means-end analysis through a dynamic physics simulation to determine the sequence of linear pushes to clear the necessary space. Simulation experiments show that our approach finds solutions in higher clutter percentages (up to 49%) compared to the straight-line push planner (37%) and RRT without pushing (18%).
