针对机械臂整理任务中的放置误差,提出通过推动错放物体来自动检测与修正的方法,在仿真和真实硬件上验证,实现了毫米级高可靠放置精度。

摘要:

使用机械臂整理物体时,最终结果的质量在很大程度上取决于可实现的放置精度。然而,即使是最先进的机器人系统也容易在操作过程的不同步骤中出现定位误差。忽略这些误差可能导致整理任务的部分或完全失败。在本文中,我们提出了一种新颖的方法,通过使用机械臂推动物体来自动检测和修正错放的物体。我们使用安装在UR5机械臂上的Robotiq二指夹爪,在仿真和真实硬件上对我们的方法进行了全面测试。在评估中,我们展示了在操作规则形状物体过程中注入的不同误差的成功补偿。因此,我们实现了毫米范围内高度可靠的物体放置精度。

英文摘要:

When arranging objects with robotic arms, the quality of the end result strongly depends on the achievable placement accuracy. However, even the most advanced robotic systems are prone to positioning errors that can occur at different steps of the manipulation process. Ignoring such errors can lead to the partial or complete failure of the arrangement. In this paper, we present a novel approach to autonomously detect and correct misplaced objects by pushing them with a robotic arm. We thoroughly tested our approach both in simulation and on real hardware using a Robotiq two-finger gripper mounted on a UR5 robotic arm. In our evaluation, we demonstrate the successful compensation for different errors injected during the manipulation of regular shaped objects. Consequently, we achieve a highly reliable object placement accuracy in the millimeter range.
