arXiv:2605.31121v1 Announce Type: cross Abstract: Outdoor vision-language navigation (VLN) in long-range, open-world environments is frequently disrupted by semantic-cue interruptions, where informative goal cues become sparse, occluded, or leave the field of view. Once such cues disappear, agents enter a cue-free phase and often degrade into backtracking, oscillatory headings, or aimless exploration. While memory-based methods attempt to bridge these gaps, they often fail under traversability-driven detours: the remembered cue direction may be infeasible, forcing detours that prolong cue-free
The continuous advancements in AI and robotics necessitate more robust navigation systems for autonomous agents operating in complex, real-world environments.
Improving outdoor vision-language navigation is crucial for the deployment of advanced autonomous systems in logistics, defense, and exploration, especially in scenarios with intermittent information.
Agents will be able to maintain mission continuity and navigate difficult terrain more effectively, even when visual cues are temporarily lost, reducing failures and increasing operational range.
