Boosting Zero-Shot VLN Via Abstract Obstacle Map-Based Waypoint Prediction with TopoGraph-And-VisitInfo-Aware Prompting

With the rapid progress of foundation models and robotics, vision-language navigation (VLN) has emerged as a key task for embodied agents with broad practical applications. We address VLN in continuous environments, a particularly challenging setting where an agent must jointly interpret natural lan…
