SkillNav: Score-Level Skill Intervention for Zero-Shot Object Goal Navigation

arXiv:2607.15758v1 Announce Type: new Abstract: Vision-Language Model (VLM) agents have advanced zero-shot object-goal navigation, yet single-frame reasoning leaves them without the cross-step behavioral awareness an embodied navigator requires, producing recurring failures such as dead-end stalls, in-room loops, and circuitous approaches to detected targets. Prompt-based remedies inflate token budgets across multi-submodule episodes and still struggle to encode inherently spatial signals such a...
