摘要:

在大规模覆盖操作中,例如海洋勘探或空中监测,单个机器人方法并不理想,因为它们可能需要太长时间来覆盖大面积。在这种情况下,多机器人方法是优选的。此外,一些现实世界的车辆是非完整的,但可以使用Dubins车辆运动学建模。本文重点介绍了使用自主水面车辆(ASV)的水环境监测。特别是,我们提出了一种新的方法来解决由Dubins车辆组成的多机器人团队完全覆盖已知环境的问题。值得注意的是,多机器人覆盖和Dubins车辆覆盖都是NP完全问题。因此,我们提出了两种基于旅行商问题的变体- K-TSP -制定和聚类算法,有效地解决了这个问题的算法。所提出的方法进行了测试,无论是在模拟,以评估其可扩展性,并与一个团队的ASV在湖上运行,以确保其在现实世界中的适用性。

英文摘要:

In large scale coverage operations, such as marine exploration or aerial monitoring, single robot approaches are not ideal, as they may take too long to cover a large area. In such scenarios, multi-robot approaches are preferable. Furthermore, several real world vehicles are non-holonomic, but can be modeled using Dubins vehicle kinematics. This paper focuses on environmental monitoring of aquatic environments using Autonomous Surface Vehicles (ASVs). In particular, we propose a novel approach for solving the problem of complete coverage of a known environment by a multi-robot team consisting of Dubins vehicles. It is worth noting that both multi-robot coverage and Dubins vehicle coverage are NP-complete problems. As such, we present two heuristics methods based on a variant of the traveling salesman problem -- k-TSP -- formulation and clustering algorithms that efficiently solve the problem. The proposed methods are tested both in simulations to assess their scalability and with a team of ASVs operating on a lake to ensure their applicability in real world.
