AgriVLN introduces a vision‑and‑language navigation benchmark (A2A) tailored for agricultural robots, comprising 1,560 episodes across six scene classes with step‑by‑step instructions and continuous actions. Existing VLN methods perform well on short instructions but poorly on long ones; to address this, the authors propose a Subtask‑Level‑Task (STL) module that decomposes complex instructions into simple subtasks. Integrating STL into the NavGPT backbone yields the AgriVLN method, improving success rate from 0.33 to 0.47 while slightly increasing navigation error from 2.76 m to 2.91 m, and the paper includes ablation and case studies on subtask quantity and scene classes.

The paper introduces Orchestra, a robotic agent that separates task planning from action generation to follow multimodal, long‑horizon instructions. Orchestra decomposes instructions into ordered subtasks, tracks progress, updates object locations, and uses a progress evaluator to decide when to advance. On the new RMBench‑Compose benchmark, Orchestra outperforms prior methods, achieving higher success rates and longer average subtask sequences, and shows improved performance on real‑world multi‑step tasks.

RiverVLN introduces the first benchmark for long‑horizon vision‑language navigation (VLN) of unmanned surface vehicles (USVs) in continuous riverine motion. The PGT‑NAV framework converts navigation instructions into an ordered sequence of visually verifiable semantic phases, maintaining an active phase online through grounded visual and motion evidence. This phase‑grounded approach reduces recursive position and heading drift, achieving a 0.79 success rate in Unity‑ROS closed‑loop tests and demonstrating transfer to real‑world USV deployment.
