摘要:

概率路径规划器的一个众所周知的弱点是所谓的窄通道问题,其中必须探索具有相对较低的被采样概率的区域以找到解路径。已经提出了许多策略来缓解这个问题,其中大多数基于偏置采样分布。当问题中出现运动学约束时,位形空间通常变成不可参数化的隐式流形。不幸的是,这使大多数现有的采样偏差方法无效,这些方法依赖于空间的显式参数化来探索。在本文中,我们提出并评估了三种新的策略,以偏置下的存在下,在运动学约束系统的狭窄通道的采样。

英文摘要:

A well-known weakness of the probabilistic path planners is the so-called narrow passage problem, where a region with a relatively low probability of being sampled must be explored to find a solution path. Many strategies have been proposed to alleviate this problem, most of them based on biasing the sampling distribution. When kinematic constraints appear in the problem, the configuration space typically becomes a non-parametrizable, implicit manifold. Unfortunately, this invalidates most of the existing sampling bias approaches, which rely on an explicit parametrization of the space to explore. In this paper, we propose and evaluate three novel strategies to bias the sampling under the presence of narrow passages in kinematically-constrained systems.
