基于蜂窝网络的协作式机器人在搜救(SAR)与应急响应中日益重要。其依赖稳定移动网络连接,常用于快速定位幸存者及探索危险或难以进入区域。然而,电池续航与持续低延迟通信限制了作业时间与移动性。针对此问题,并结合5G/6G网络演进能力,本文提出一种包含任务规划与执行阶段的新型SAR框架,以优化机器人部署。该框架综合考虑探索区域大小、地形高程、机器人数量、通信相关的能耗模型、期望探索速率及目标响应时间,确定最小所需机器人数量及其最优路径,确保有效覆盖与及时数据回传。结果表明,轮式与四足机器人在机器人数量、覆盖面积与响应时间间存在权衡关系。此外,量化分析显示引入地形高程数据可显著降低任务时长与能耗,体现将真实环境因素(如信号传播影响)纳入规划的重要性。该框架为利用下一代移动网络提升自主搜救效率提供关键洞见。
原文摘要 · Abstract (English)
Cellular-enabled collaborative robots are becoming paramount in Search-and-Rescue (SAR) and emergency response. Crucially dependent on resilient mobile network connectivity, they serve as invaluable assets for tasks like rapid victim localization and the exploration of hazardous, otherwise unreachable areas. However, their reliance on battery power and the need for persistent, low-latency communication limit operational time and mobility. To address this, and considering the evolving capabilities of 5G/6G networks, we propose a novel SAR framework that includes Mission Planning and Mission Execution phases and that optimizes robot deployment. By considering parameters such as the exploration area size, terrain elevation, robot fleet size, communication-influenced energy profiles, desired exploration rate, and target response time, our framework determines the minimum number of robots required and their optimal paths to ensure effective coverage and timely data backhaul over mobile networks. Our results demonstrate the trade-offs between number of robots, explored area, and response time for wheeled and quadruped robots. Further, we quantify the impact of terrain elevation data on mission time and energy consumption, showing the benefits of incorporating real-world environmental factors that might also affect mobile signal propagation and connectivity into SAR planning. This framework provides critical insights for leveraging next-generation mobile networks to enhance autonomous SAR operations.
