用神经场直接生成连续机器人轨迹,无需后处理。

FoldPath: End-to-End Object-Centric Motion Generation via Modulated Implicit Paths

  • 将机器人运动建模为连续函数,避免离散点拼接
  • 仅用70个专家样本即实现工业级轨迹生成
  • 适合需要高精度路径的智能制造场景

面向自动化制造中高精度机器人运动需求,如喷涂与焊接,物体中心运动生成(OCMG)至关重要。现有方法或依赖启发式规则,或采用需敏感后处理的学习管道。本文提出FoldPath,一种基于神经场的端到端物体中心运动生成方法。不同于以往预测离散末端执行器点的方法,FoldPath将机器人运动建模为连续函数,隐式编码平滑路径,消除对离散点拼接与排序的脆弱后处理步骤。实验表明,该方法在复杂3D几何下表现更优,且仅需70个专家样本即可在真实工业环境中实现良好泛化。我们在真实仿真环境进行了全面验证,并引入新评估指标,系统性评价长时程机器人路径,推动OCMG向实用化迈进。

原文摘要 · Abstract (English)

Object-Centric Motion Generation (OCMG) is instrumental in advancing automated manufacturing processes, particularly in domains requiring high-precision expert robotic motions, such as spray painting and welding. To realize effective automation, robust algorithms are essential for generating extended, object-aware trajectories across intricate 3D geometries. However, contemporary OCMG techniques are either based on ad-hoc heuristics or employ learning-based pipelines that are still reliant on sensitive post-processing steps to generate executable paths. We introduce FoldPath, a novel, end-to-end, neural field based method for OCMG. Unlike prior deep learning approaches that predict discrete sequences of end-effector waypoints, FoldPath learns the robot motion as a continuous function, thus implicitly encoding smooth output paths. This paradigm shift eliminates the need for brittle post-processing steps that concatenate and order the predicted discrete waypoints. Particularly, our approach demonstrates superior predictive performance compared to recently proposed learning-based methods, and attains generalization capabilities even in real industrial settings, where only a limited amount of 70 expert samples are provided. We validate FoldPath through comprehensive experiments in a realistic simulation environment and introduce new, rigorous metrics designed to comprehensively evaluate long-horizon robotic paths, thus advancing the OCMG task towards practical maturity.
