- 分角色大模型代理协作,从语言指令生成可执行动作
- 无需预设环境信息,能处理多样工具与长序列任务
- 适合动态复杂场景,推动机器人自主执行新范式
随着机器人系统在复杂现实环境中的日益融合,亟需无需依赖大量预编程知识即可理解并执行自然语言指令的方法。本文提出PLATO,一种创新系统,利用专用大语言模型代理处理自然语言输入,理解环境,预测工具可用性,并生成机器人可执行的动作。与依赖硬编码环境信息的传统系统不同,PLATO采用模块化专用代理架构,在无初始环境知识前提下运行。这些代理识别场景中的物体及其位置,生成全面的高层计划,将其转化为一系列低层动作,并验证每步完成情况。系统特别针对具有挑战性的工具使用任务进行测试,涉及多种物体且需长时程规划。PLATO的设计使其能适应动态和非结构化环境,显著提升灵活性与鲁棒性。通过在多种复杂场景下的评估,证明其具备应对多样化任务的能力,为大模型与机器人平台集成提供了新方案,推动了自主机器人任务执行的前沿进展。视频及提示细节请见项目网站:https://sites.google.com/andrew.cmu.edu/plato
原文摘要 · Abstract (English)
As robotic systems become increasingly integrated into complex real-world environments, there is a growing need for approaches that enable robots to understand and act upon natural language instructions without relying on extensive pre-programmed knowledge of their surroundings. This paper presents PLATO, an innovative system that addresses this challenge by leveraging specialized large language model agents to process natural language inputs, understand the environment, predict tool affordances, and generate executable actions for robotic systems. Unlike traditional systems that depend on hard-coded environmental information, PLATO employs a modular architecture of specialized agents to operate without any initial knowledge of the environment. These agents identify objects and their locations within the scene, generate a comprehensive high-level plan, translate this plan into a series of low-level actions, and verify the completion of each step. The system is particularly tested on challenging tool-use tasks, which involve handling diverse objects and require long-horizon planning. PLATO's design allows it to adapt to dynamic and unstructured settings, significantly enhancing its flexibility and robustness. By evaluating the system across various complex scenarios, we demonstrate its capability to tackle a diverse range of tasks and offer a novel solution to integrate LLMs with robotic platforms, advancing the state-of-the-art in autonomous robotic task execution.
