摘要:

基于采样的规划器在具有许多自由度的机器人运动规划中已经取得了成功,但是在配置空间内存在狭窄通道时仍然是无效的。存在几种在关键区域产生样本的概率路线图规划器,提高了效率。在本文中,我们提出了一个这样的探试法,称为基于障碍的概率路线图规划或OBPRM,使用几何概率理论的成功概率的评估。结果表明,在$n$维位形空间障碍物表面周围生成自由样点的成功概率与障碍物的表面积成正比。

英文摘要:

Sampling based planners have been successful in robot motion planning, with many degrees of freedom, but still remain ineffective in the presence of narrow passages within the configuration space. There exist several heuristics, which generate samples in the critical regions and improve the efficiency of probabilistic roadmap planners. In this paper, we present an evaluation of success probability of one such heuristic method, called obstacle based probabilistic roadmap planners or OBPRM, using geometric probability theory. The result indicates that the probability of success of generating free sample points around the surface of the $n$ dimensional configuration space obstacle is directly proportional to the surface area of the obstacles.
