交互式实例导航任务 （Interactive Instance Goal Navigation, IIGN） 本工作由上海人工智能实验室、中国科学技术大学、浙江大学、香港大学 的研究者们共同完成。 如果将一台在视觉语言导航（VLN）任务中表现优异的机器人直接搬进家庭场景，往往会遇到不少实 际问题。 首先是使用门槛偏高：传统 VLN 需要用户给出又长又精确的路线式指令，例如 "从门口直走三步，看到门右转，再往前……"，这会显著增加沟通成本，降 低日常使用体验。 论文标题：VL-LN Bench: Towards Long-horizon Goal-oriented Navigation with Active Dialogs 项目主页：https://0309hws.github.io/VL-LN.github.io/ ArXiv 论文：https://arxiv.org/abs/2512.22342 Hugging Face 数据集： https://huggingface.co/datasets/InternRobotics/VL-LN-Bench Hugging Face 模型：https://huggi ...
