An enhanced covert navigation framework that leverages LiDAR data, height maps, cover maps, and potential threat maps, along with offline reinforcement learning, to enable autonomous robots to navigate efficiently while minimizing exposure to threats and maximizing cover utilization in complex outdoor environments.
TopoNav, a novel framework, integrates active topological mapping, hierarchical reinforcement learning, and intrinsic motivation to enable efficient and autonomous exploration and navigation in unknown environments with sparse rewards.
