When, Where, and What to Correct: Human-Guided Adaptive Residual Correction for Robot Policies
AI 导读
研究者提出轻量后训练模块 Adaptive Residual Correction(ARC),在冻结策略之上用强化学习学习残差修正,并以稀疏人类纠正引导自主探索。在真实机器人的三项精密操作任务上,ARC 将平均任务成功率从 33.3% 提升至 75.0%。人类纠正定义了七关节残差空间中 2-3 维的任务相关子空间,保留 96.0-97.7% 的纠正幅度平方。

Abstract:Imitation policies that reliably execute most of a manipulation trajectory can still fail in localized regions requiring last-mile precision. Updating the full policy or exploring residual actions everywhere treats this local failure as a global learning problem. We introduce Adaptive Residual Correction (ARC), a lightweight post-training module that uses reinforcement learning (RL) to learn a residual correction on top of a frozen policy while using sparse human corrections to structure autonomous exploration. Rather than treating human corrections as imitation targets, ARC uses pre-intervention states to determine 'when' residual control should become active and correction geometry to determine 'where' in residual action space autonomous refinement should explore; task reward determines 'what' residual is ultimately executed. Across three precision-manipulation tasks on a real robot, ARC improves average task success from 33.3% to 75.0%. The human corrections define task-dependent 2-3 dimensional subspaces of the seven-joint residual space that retain 96.0-97.7% of squared correction magnitude. Together, these results show that sparse human corrections can localize and constrain autonomous post-training without requiring the observed correction itself to serve as the final action target.
