A Risk-Aware Safety Framework for UWB-Localized Quadrotors: Geometry-Aware Error Compensation and Belief-Space Collision Avoidance
Ultra-wideband (UWB) positioning provides cost-effective localization for quadrotors in global navigation satellite system (GNSS)-denied environments, but geometry-dependent, heavy-tailed errors challenge state estimation and safety-critical control. This paper presents a risk-aware framework linking geometry-aware err...
