摘要:

机械零件的高精度装配要求精度超过机器人精度。在当前制造中使用的常规部件配合方法需要在部署之前对许多参数进行繁琐的调整。我们展示了机器人如何通过强化学习训练递归神经网络来成功地执行紧间隙钉孔任务。除了节省人工的努力,所提出的技术还显示出对钉孔任务的位置和角度误差的鲁棒性。神经网络通过观察机器人传感器估计系统状态来学习采取最佳动作。我们所提出的方法的优点进行了实验验证的7轴关节式机器人手臂。

英文摘要:

High precision assembly of mechanical parts requires accuracy exceeding the robot precision. Conventional part mating methods used in the current manufacturing requires tedious tuning of numerous parameters before deployment. We show how the robot can successfully perform a tight clearance peg-in-hole task through training a recurrent neural network with reinforcement learning. In addition to saving the manual effort, the proposed technique also shows robustness against position and angle errors for the peg-in-hole task. The neural network learns to take the optimal action by observing the robot sensors to estimate the system state. The advantages of our proposed method is validated experimentally on a 7-axis articulated robot arm.
