摘要:

本文提出了一种新的算法,称为$ε^*$ +,使用能量受限的自主车辆的未知环境的在线覆盖路径规划。由于有限的电池尺寸,能量受限的车辆具有有限的操作时间持续时间。因此,在执行覆盖轨迹时,车辆必须在电池耗尽之前返回充电站进行充电。在这方面,$ε^*$ +算法使得车辆能够基于在整个覆盖过程中监测的剩余能量退回到充电站。这之后是一个前进轨迹,它将飞行器带到附近未探测的航路点重新开始覆盖过程,而不是将其带回到撤退轨迹的先前遗留点;从而减少了整体覆盖时间。所提出的$ε^*$ +算法是$ε^*$算法的扩展,该算法利用探索性图灵机(ETM)作为管理器,以来回轨迹导航车辆以实现完全覆盖。$ε^*$ +算法的性能在复杂场景中使用Player/Stage(高保真机器人模拟器)进行了验证。

英文摘要:

This paper presents a novel algorithm, called $ε^*$+, for online coverage path planning of unknown environments using energy-constrained autonomous vehicles. Due to limited battery size, the energy-constrained vehicles have limited duration of operation time. Therefore, while executing a coverage trajectory, the vehicle has to return to the charging station for a recharge before the battery runs out. In this regard, the $ε^*$+ algorithm enables the vehicle to retreat back to the charging station based on the remaining energy which is monitored throughout the coverage process. This is followed by an advance trajectory that takes the vehicle to a near by unexplored waypoint to restart the coverage process, instead of taking it back to the previous left over point of the retreat trajectory; thus reducing the overall coverage time. The proposed $ε^*$+ algorithm is an extension of the $ε^*$ algorithm, which utilizes an Exploratory Turing Machine (ETM) as a supervisor to navigate the vehicle with back and forth trajectory for complete coverage. The performance of the $ε^*$+ algorithm is validated on complex scenarios using Player/Stage which is a high-fidelity robotic simulator.
