AI总结:

本研究提出语言引导的多接触点放置流水线Words2Contact,可将自然语言指令转化为机器人支撑接触点预测并支持迭代修正,经基准测试和人形机器人真实实验验证,能有效辅助人机协作与遥操作场景下的接触点定位。

摘要:

本文提出Words2Contact,这是一种借助大语言模型和视觉语言模型的语言引导式多接触点放置流水线。我们的方法是语言辅助遥操作与人机协作的关键组件,在该场景下,人类操作员可在机器人进行全身伸展或操作前,用自然语言指示机器人将支撑接触点放置在何处。Words2Contact将人类操作员的口头指令转化为接触点放置预测,还能处理迭代修正,直到人类对机器人视野中识别出的接触位置满意为止。我们针对接触预测任务,在模型规模与性能上对当前最优的LLM和VLM进行了基准测试。我们验证了迭代修正流程的有效性,结果显示即便是无经验的用户也能快速学会如何指示系统以获得准确位置。最后,我们通过Talos人形机器人的真实世界实验验证了Words2Contact:人类操作员指示机器人在不同位置和表面放置支撑接触点,以避免在抓取远处物体时摔倒。

英文摘要:

This paper presents Words2Contact, a language-guided multi-contact placement pipeline leveraging large language models and vision language models. Our method is a key component for language-assisted teleoperation and human-robot cooperation, where human operators can instruct the robots where to place their support contacts before whole-body reaching or manipulation using natural language. Words2Contact transforms the verbal instructions of a human operator into contact placement predictions; it also deals with iterative corrections, until the human is satisfied with the contact location identified in the robot's field of view. We benchmark state-of-the-art LLMs and VLMs for size and performance in contact prediction. We demonstrate the effectiveness of the iterative correction process, showing that users, even naive, quickly learn how to instruct the system to obtain accurate locations. Finally, we validate Words2Contact in real-world experiments with the Talos humanoid robot, instructed by human operators to place support contacts on different locations and surfaces to avoid falling when reaching for distant objects.
