AI总结:

本文提出一种多机器人规划方法,结合学习估计不确定环境因素与基于模型的长期协调规划,以高效完成复杂任务。

摘要:

我们希望多机器人团队在最短时间内完成复杂任务,其中相关任务对象的位置未知。有效的任务完成需要对任务相关对象的可能位置进行长时间预测,个体行动对整体进展的贡献,以及团队协作的协调。在这种情况下规划极具挑战性:即使任务相关信息部分已知,协调哪台机器人执行哪个动作以及何时执行也困难,不确定性引入了每个动作的多种可能结果,进一步复杂化了长时间决策和协调。为了解决这个问题,我们提出了一种多机器人规划抽象,该方法整合了学习以估计环境的不确定因素与基于模型的长期协调规划。我们展示了我们的方法在大型ProcTHOR家庭环境中的1、2和3机器人团队中的高效多阶段任务规划,并在现实家庭环境中用两台LoCoBot移动机器人展示了方法的有效性。

英文摘要:

We want a multi-robot team to complete complex tasks in minimum time where the locations of task-relevant objects are not known. Effective task completion requires reasoning over long horizons about the likely locations of task-relevant objects, how individual actions contribute to overall progress, and how to coordinate team efforts. Planning in this setting is extremely challenging: even when task-relevant information is partially known, coordinating which robot performs which action and when is difficult, and uncertainty introduces a multiplicity of possible outcomes for each action, which further complicates long-horizon decision-making and coordination. To address this, we propose a multi-robot planning abstraction that integrates learning to estimate uncertain aspects of the environment with model-based planning for long-horizon coordination. We demonstrate the efficient multi-stage task planning of our approach for 1, 2, and 3 robot teams over competitive baselines in large ProcTHOR household environments. Additionally, we demonstrate the effectiveness of our approach with a team of two LoCoBot mobile robots in real household settings.
