AI总结:

针对自由端线缆动态操作中端点到达机器人可达范围外目标位置的问题,提出一种有监督学习方法,结合物理标定的仿真器收集数据训练模型,在UR5机器人上实现中位误差低至线缆长度的22%-35%,优于解析和高斯过程基线。

摘要:

自由端线缆的动态操作在家庭、仓库和制造工厂的线缆管理中具有应用价值。我们提出了一种用于自由端线缆动态操作的有监督学习方法,重点关注将线缆端点送达指定目标位置的问题,该目标位置可能位于机器人末端执行器的可达工作空间之外。我们开发了一个仿真器,对其进行了调整以使其与物理线缆实验高度匹配,随后收集训练数据以学习动态线缆操作。我们使用3种线缆和一台物理UR5机器人进行评估。在3种线缆上进行的32x5次试验结果表明,物理UR5机器人能够达到的中位误差距离介于线缆长度的22%至35%之间,相比解析基线提升了21%,相比高斯过程(Gaussian Process)基线提升了7%,且具有更低的四分位距(IQR)。

英文摘要:

Dynamic manipulation of free-end cables has applications for cable management in homes, warehouses and manufacturing plants. We present a supervised learning approach for dynamic manipulation of free-end cables, focusing on the problem of getting the cable endpoint to a designated target position, which may lie outside the reachable workspace of the robot end effector. We present a simulator, tune it to closely match experiments with physical cables, and then collect training data for learning dynamic cable manipulation. We evaluate with 3 cables and a physical UR5 robot. Results over 32x5 trials on 3 cables suggest that a physical UR5 robot can attain a median error distance ranging from 22% to 35% of the cable length among cables, outperforming an analytic baseline by 21% and a Gaussian Process baseline by 7% with lower interquartile range (IQR).
