受人类导航启发,构建局部空间隐式帧与全局拓扑图结合的新方法。

Bio-Inspired Hybrid Map: Spatial Implicit Local Frames and Topological Map for Mobile Cobot Navigation

  • 用局部空间隐式帧模拟人类短期空间记忆
  • 融合局部帧与拓扑图实现高效全局导航
  • 适合复杂动态环境下的移动协作机器人

导航是移动机器人在复杂动态环境中自主运行的基础能力。传统方法使用概率模型同时进行定位与建图,近年研究采用模仿学习和强化学习等类人学习方法提升导航效果,但存在计算开销高、全局地图不一致及对未见环境泛化能力差的问题。本文受人类在新环境中感知与导航方式的启发,提出一种新方法:首先构建局部空间隐式帧,以融合空间信息与学习特征的方式表征短期关键空间信息;然后将这些局部帧集成到以因子图表示的全局拓扑地图中;最后设计基于RRT*的新型导航算法,利用局部帧与拓扑图实现高效导航。我们在真实世界数据集和实验室环境进行了大量实验验证,代码已开源。

原文摘要 · Abstract (English)

Navigation is a fundamental capacity for mobile robots, enabling them to operate autonomously in complex and dynamic environments. Conventional approaches use probabilistic models to localize robots and build maps simultaneously using sensor observations. Recent approaches employ human-inspired learning, such as imitation and reinforcement learning, to navigate robots more effectively. However, these methods suffer from high computational costs, global map inconsistency, and poor generalization to unseen environments. This paper presents a novel method inspired by how humans perceive and navigate themselves effectively in novel environments. Specifically, we first build local frames that mimic how humans represent essential spatial information in the short term. Points in local frames are hybrid representations, including spatial information and learned features, so-called spatial-implicit local frames. Then, we integrate spatial-implicit local frames into the global topological map represented as a factor graph. Lastly, we developed a novel navigation algorithm based on Rapid-Exploring Random Tree Star (RRT*) that leverages spatial-implicit local frames and the topological map to navigate effectively in environments. To validate our approach, we conduct extensive experiments in real-world datasets and in-lab environments.
