摘要:

针对一个具有异构能力的多机器人系统,本文提出了一种机制,当异常环境条件如天气事件或对抗攻击影响任务内机器人的性能时,该机制以弹性的方式将机器人分配到任务中。我们的主要目标是确保为每个任务分配必要的资源水平,以分配给任务的机器人的聚合能力来衡量。通过跟踪外部扰动下的任务性能偏差,我们的框架量化了机器人能力(例如,视觉感知或空中机动性)受到环境条件的影响。这使得基于优化的框架能够根据每个任务中最退化的能力灵活地将机器人重新分配给任务。在面对资源的限制和不利的环境条件下,我们的算法最低限度地放松了相应的一些任务的资源约束,从而表现出一个优雅的性能下降。在多机器人覆盖和目标跟踪场景中的仿真实验证明了该方法的有效性。

英文摘要:

For a multi-robot system equipped with heterogeneous capabilities, this paper presents a mechanism to allocate robots to tasks in a resilient manner when anomalous environmental conditions such as weather events or adversarial attacks affect the performance of robots within the tasks. Our primary objective is to ensure that each task is assigned the requisite level of resources, measured as the aggregated capabilities of the robots allocated to the task. By keeping track of task performance deviations under external perturbations, our framework quantifies the extent to which robot capabilities (e.g., visual sensing or aerial mobility) are affected by environmental conditions. This enables an optimization-based framework to flexibly reallocate robots to tasks based on the most degraded capabilities within each task. In the face of resource limitations and adverse environmental conditions, our algorithm minimally relaxes the resource constraints corresponding to some tasks, thus exhibiting a graceful degradation of performance. Simulated experiments in a multi-robot coverage and target tracking scenario demonstrate the efficacy of the proposed approach.
