摘要:

多机器人协作凭借应对各类复杂场景的能力,已成为未知环境探索中不可或缺的组成部分。基于势场的方法因效率高、行进成本低,被广泛应用于自主探索领域,但探索速度与协作能力仍是颇具挑战的研究方向。为此,我们提出分布式多机器人势场探索方法(DMPF-Explore)。具体而言,首先提出基于子地图的分布式多机器人协同样图方法(DSMC-Map),该方法可通过合并各机器人的局部地图,高效估计机器人轨迹并构建全局地图。其次,引入融合改进波前距离与有色噪声的势场探索策略(MWF-CN),该策略扩展了可访问前沿邻域,且有色噪声可推动探索性能提升。我们在仿真与真实场景中部署了所提探索方法,结果表明,该方法在探索速度与协作能力方面均优于现有方法。

英文摘要:

Multi-robot collaboration has become a needed component in unknown environment exploration due to its ability to accomplish various challenging situations. Potential-field-based methods are widely used for autonomous exploration because of their high efficiency and low travel cost. However, exploration speed and collaboration ability are still challenging topics. Therefore, we propose a Distributed Multi-Robot Potential-Field-Based Exploration (DMPF-Explore). In particular, we first present a Distributed Submap-Based Multi-Robot Collaborative Mapping Method (DSMC-Map), which can efficiently estimate the robot trajectories and construct the global map by merging the local maps from each robot. Second, we introduce a Potential-Field-Based Exploration Strategy Augmented with Modified Wave-Front Distance and Colored Noises (MWF-CN), in which the accessible frontier neighborhood is extended, and the colored noise provokes the enhancement of exploration performance. The proposed exploration method is deployed for simulation and real-world scenarios. The results show that our approach outperforms the existing ones regarding exploration speed and collaboration ability.
