Why it matters
FLUX linearizes probability flow to replace iterative denoising, making inference 47% faster than prior methods. Its ability to generalize across radically different robotic embodiments without fine-tuning represents a major step toward a foundation model for autonomous navigation.
From the abstract
Autonomous navigation requires a broad spectrum of skills, from static goal-reaching to dynamic social traversal, yet evaluation remains fragmented across disparate protocols. We introduce DynBench, a dynamic navigation benchmark featuring physically valid crowd simulation. Combined with existing static protocols, it supports comprehensive evaluation across six fundamental navigation tasks. Within this framework, we propose FLUX, the first flow-based unified navigation policy. By linearizing pro
