Rapid Autonomous Exploration of Large-Scale Environments for Ground Robots Based on Region Partitioning

ICRA 2025

Autonomous exploration in large environments often leads to inefficient long backtracking, as distant targets are prioritized over closer ones. In this work, a hierarchical planning method is proposed, which employs region partitioning to systematically address the aforementioned issue. The space is
