Core Concepts
Offloading sensor requirements to guide smaller UAVs through cluttered environments.
Abstract
The article explores a novel approach where a primary UAV guides a secondary UAV through cluttered environments by offloading the sensing requirements. The primary UAV constructs an occupancy map, plans collision-free paths, and guides the secondary UAV using LiDAR-based relative localization. Real-world experiments with heterogeneous teams validate the proposed framework's effectiveness.
