📝 摘要(中文)
在大型建筑中进行自主配送需要跨多个空间层级进行协调规划,包括建筑、楼层和房间,同时确保调度效率。现有方法往往仅关注算法开发,忽视与物理机器人平台的集成,且在真实场景中验证性能的案例较少。此外,许多方法未考虑分层建筑结构和房间级隐私约束,限制了实际应用。为了解决这些挑战,本文提出了一种基于建筑-楼层-房间抽象的分层配送框架,显著降低了优化复杂性。我们构建了一个建筑感知的有容量车辆路径规划问题(CVRP)扩展,明确建模了建筑间、楼层间的连通性、房间级访问约束和隐私敏感区域,从而实现全球可行且符合隐私要求的任务分配和路径规划。该框架在真实的多传感器机器人平台上进行了验证,展示了可靠的多楼层配送,路径合理性和整体效率得到了提升。

📄 摘要(原文)
Autonomous delivery in large scale buildings requires coordinated planning across multiple spatial levels, including building, floor, and room, while ensuring scheduling efficiency. Existing methods often focus solely on algorithmic development, neglecting integration with physical robotic platforms, and rarely validate performance in real world scenarios. Many approaches also overlook hierarchical building structures and room level privacy constraints, limiting practical applicability. To address these challenges, this paper presents a hierarchical delivery framework based on a Building-Floor-Room abstraction, which decomposes the problem across multiple levels to significantly reduce optimization complexity. We formulate a building aware extension of the capacitated vehicle routing problem (CVRP) that explicitly models inter building and inter floor connectivity, room level access constraints, and privacy sensitive areas, enabling globally feasible and privacy compliant task assignment and routing. Based on this hierarchical model, the framework can evaluate delivery efficiency across different building layouts and optimize depot placement for specific configurations. At the execution level, we introduce a novel hardware design for non interactive, privacy preserving delivery, supported by reachability aware distances and a closed loop mapping, localization, and navigation system, ensuring consistency between planned routes and physical navigation. The proposed framework is validated on a real multi sensor robotic platform, demonstrating reliable multi floor delivery with improved path rationality and overall efficiency.
