本文提出优先感知多机器人覆盖率路径规划方法,通过两阶段框架结合贪心分配与局部搜索,有效减少优先区域延迟并优化完成时间。

摘要:

多机器人系统被广泛用于需要在大环境中高效协调的覆盖任务。在多机器人覆盖率路径规划(MCPP)中,通常的目标是通过生成非重叠路径来最小化完成时间。然而,大多数现有方法假设区域重要性均匀,限制了在某些区域需要更快关注的场景中的有效性。我们引入了优先感知的MCPP(PA-MCPP)问题,其中环境的一部分被指定为优先区域并关联权重。目标是按字典序最小化总优先权重延迟和整体完成时间。为此,我们提出了一种可扩展的两阶段框架,结合(1)贪心区域分配与局部搜索、基于生成树的路径规划,以及(2)Steiner树引导的剩余覆盖。在多样化的场景实验中,我们的方法相比标准MCPP基线显著减少了优先权重延迟,同时保持了有竞争力的完成时间。敏感性分析进一步显示,该方法在机器人数量上具有良好的可扩展性,且通过调整优先权重可以有效控制区域覆盖行为。

英文摘要:

Multi-robot systems are widely used for coverage tasks that require efficient coordination across large environments. In Multi-Robot Coverage Path Planning (MCPP), the objective is typically to minimize the makespan by generating non-overlapping paths for full-area coverage. However, most existing methods assume uniform importance across regions, limiting their effectiveness in scenarios where some zones require faster attention. We introduce the Priority-Aware MCPP (PA-MCPP) problem, where a subset of the environment is designated as prioritized zones with associated weights. The goal is to minimize, in lexicographic order, the total priority-weighted latency of zone coverage and the overall makespan. To address this, we propose a scalable two-phase framework combining (1) greedy zone assignment with local search, spanning-tree-based path planning, and (2) Steiner-tree-guided residual coverage. Experiments across diverse scenarios demonstrate that our method significantly reduces priority-weighted latency compared to standard MCPP baselines, while maintaining competitive makespan. Sensitivity analyses further show that the method scales well with the number of robots and that zone coverage behavior can be effectively controlled by adjusting priority weights.
