摘要:

本文研究了使用图神经网络(GNNs)的经典运动规划问题的可行性。我们建议使用GNN的能力来指导连续和离散规划算法,该能力使用称为置换不变性的属性来鲁棒地编码规划空间的拓扑结构。我们提出了两种技术,在密集的固定图的低维问题和基于采样的GNNs高维问题的GNNs。我们研究了GNN解决规划问题的能力,例如识别关键节点或学习快速探索随机树(RRT)中的采样分布。临界采样、钟摆和六自由度机器人手臂的实验表明,GNN改进了传统的分析方法以及使用全连接或卷积神经网络的学习方法。

英文摘要:

This paper investigates the feasibility of using Graph Neural Networks (GNNs) for classical motion planning problems. We propose guiding both continuous and discrete planning algorithms using GNNs' ability to robustly encode the topology of the planning space using a property called permutation invariance. We present two techniques, GNNs over dense fixed graphs for low-dimensional problems and sampling-based GNNs for high-dimensional problems. We examine the ability of a GNN to tackle planning problems such as identifying critical nodes or learning the sampling distribution in Rapidly-exploring Random Trees (RRT). Experiments with critical sampling, a pendulum and a six DoF robot arm show GNNs improve on traditional analytic methods as well as learning approaches using fully-connected or convolutional neural networks.
