论文摘要
当机器人在具有非结构化地形的现实世界越野环境中运行时,适应其导航政策的能力对于有效且安全的导航至关重要。但是,越野地形为机器人导航带来了一些挑战,包括动态障碍和地形不确定性,导致遍历或导航故障效率低下。为了应对这些挑战,我们通过谈判引入了一种新颖的适应方法,使地面机器人能够通过谈判过程来调整其导航行为。我们的方法首先学习了各种导航政策的预测模型,以充当地形感知的当地控制器和计划者。然后,通过新的谈判过程,我们的方法从各种政策与环境的互动中学习,以在线方式达成最佳策略组合,以使机器人导航适应即时的非结构化越野地形。此外,我们实施了一种新的优化算法,该算法在执行过程中实时提供了机器人谈判的最佳解决方案。实验结果已经验证了我们通过谈判的适应方法优于机器人导航的先前方法,尤其是在看不见和不确定的动态地形上。
When robots operate in real-world off-road environments with unstructured terrains, the ability to adapt their navigational policy is critical for effective and safe navigation. However, off-road terrains introduce several challenges to robot navigation, including dynamic obstacles and terrain uncertainty, leading to inefficient traversal or navigation failures. To address these challenges, we introduce a novel approach for adaptation by negotiation that enables a ground robot to adjust its navigational behaviors through a negotiation process. Our approach first learns prediction models for various navigational policies to function as a terrain-aware joint local controller and planner. Then, through a new negotiation process, our approach learns from various policies' interactions with the environment to agree on the optimal combination of policies in an online fashion to adapt robot navigation to unstructured off-road terrains on the fly. Additionally, we implement a new optimization algorithm that offers the optimal solution for robot negotiation in real-time during execution. Experimental results have validated that our method for adaptation by negotiation outperforms previous methods for robot navigation, especially over unseen and uncertain dynamic terrains.
