AI总结:

EPoG通过结合基于图的全局规划器与LLM的定位局部规划器,实现探索与顺序操作规划的无缝结合,有效提升机器人在部分已知环境中的任务执行效率。

摘要:

在部分已知的环境中,机器人必须将探索以获取信息与任务规划结合起来以实现高效的执行。为了解决这一挑战,我们提出了EPoG,一种基于场景图的探索式顺序操作规划框架。EPoG将基于图的全局规划器与基于大语言模型(LLM)的定位局部规划器相结合,通过持续更新信念图来表示已知和未知的对象。通过计算目标图与信念图之间的图编辑操作生成动作序列,按时间依赖性和移动成本排序。这种方法无缝地结合了探索和顺序操作规划。在46个现实家庭场景和5个长周期日常物体运输任务的消融研究中,EPoG的成功率达到了91.3%,平均减少了36.1%的旅行距离。此外,一个物理移动机械臂在未知和动态环境中成功执行了复杂任务,证明了EPoG在现实应用中的潜力。

英文摘要:

In partially known environments, robots must combine exploration to gather information with task planning for efficient execution. To address this challenge, we propose EPoG, an Exploration-based sequential manipulation Planning framework on Scene Graphs. EPoG integrates a graph-based global planner with a Large Language Model (LLM)-based situated local planner, continuously updating a belief graph using observations and LLM predictions to represent known and unknown objects. Action sequences are generated by computing graph edit operations between the goal and belief graphs, ordered by temporal dependencies and movement costs. This approach seamlessly combines exploration and sequential manipulation planning. In ablation studies across 46 realistic household scenes and 5 long-horizon daily object transportation tasks, EPoG achieved a success rate of 91.3%, reducing travel distance by 36.1% on average. Furthermore, a physical mobile manipulator successfully executed complex tasks in unknown and dynamic environments, demonstrating EPoG's potential for real-world applications.
