利用编队结构定位固定目标的多机器人覆盖

Multi-robot coverage to locate fixed targets using formation structures

Ghent University(根特大学)

Jonathan Rogge, Dirk Aeyels

摘要:

提出了一种引导多机器人系统在未知环境中搜索固定目标的算法。要扫描的区域包含未知数量的未知大小和形状的凸形障碍物。该算法覆盖了整个自由空间的清扫方式,因此依赖于使用机器人编队。机器人组的几何形状是一个侧线编队,允许在通过障碍物时分裂和重新加入。我们的主要目标是利用这种编队结构,以减少机器人资源到最低限度。每个机器人都有有限的内存。没有记录地形信息。两个机器人之间的通信只能达到机器人之间的最大距离,并且如果两个机器人之间的视线不被阻挡。不允许广播功能和间接通信。禁止监督控制。配备GPS的机器人数量尽可能少。该算法的应用是雷区清除,搜索和救援任务,拦截任务。仿真包括在互联网上,并提供,证明了算法的灵活性。

英文摘要:

This paper develops an algorithm that guides a multi-robot system in an unknown environment in search of fixed targets. The area to be scanned contains an unknown number of convex obstacles of unknown size and shape. The algorithm covers the entire free space in a sweeping fashion and as such relies on the use of robot formations. The geometry of the robot group is a lateral line formation, which is allowed to split and rejoin when passing obstacles. It is our main goal to exploit this formation structure in order to reduce robot resources to a minimum. Each robot has a limited and finite amount of memory available. No information of the topography is recorded. Communication between two robots is only possible up to a maximum inter-robot distance, and if the line-of-sight between both robots is not obstructed. Broadcasting capabilities and indirect communication are not allowed. Supervisory control is prohibited. The number of robots equipped with GPS is kept as small as possible. Applications of the algorithm are mine field clearance, search-and-rescue missions, and intercept missions. Simulations are included and made available on the internet, demonstrating the flexibility of the algorithm.
