AnchorVLN: Geometry-Anchored Vision-Language Grounding Reasoning for Open-Vocabulary Navigation

AnchorVLN is an open‑vocabulary vision‑language navigation system that separates semantic proposals from geometric metrics. It uses a VLM to generate semantics while a geometry module supplies reliable metric quantities such as range and bearing, all within a Model Context Protocol server. The system achieves 64.4% on instruction following and improves object‑reference accuracy, reducing median center error from 3.37 m to 2.48 m.

RTNav: Towards Real-Time Zero-Shot Object Navigation

RTNav is a new architecture for real‑time zero‑shot object navigation that explicitly accounts for inference latency, asynchronous environment stepping, and bounded compute. It addresses the performance drop seen in existing methods when deployed under realistic timing constraints. On real‑time variants of HM3D‑v1, HM3D‑v2, and HM3D‑OVON, RTNav boosts success rate by up to 11% and Success weighted by Completion Time by up to 5.1 points.
