摘要:

对机器人任务自动化的需求日益增加。接触丰富的任务,其中多个接触过渡发生在一系列的操作,正在被广泛研究,以实现高精度。在这项研究中,我们提出了一种方法,使用强化学习(RL),以实现高性能的机器人执行装配任务,需要精确的接触对象,而不会造成损害。该方法保证了刚度矩阵的在线生成,有助于提高局部轨迹优化的性能。由于轨迹规划的采样时间短,该方法具有响应速度快的优点。通过两个接触丰富的任务的实验验证了该方法的有效性。结果表明,该方法可以实现在各种接触丰富的操作。一个演示视频显示了性能。(https://youtu.be/gxSCl7Tp4-0)

英文摘要:

There is an increased demand for task automation in robots. Contact-rich tasks, wherein multiple contact transitions occur in a series of operations, are extensively being studied to realize high accuracy. In this study, we propose a methodology that uses reinforcement learning (RL) to achieve high performance in robots for the execution of assembly tasks that require precise contact with objects without causing damage. The proposed method ensures the online generation of stiffness matrices that help improve the performance of local trajectory optimization. The method has an advantage of rapid response owing to short sampling time of the trajectory planning. The effectiveness of the method was verified via experiments involving two contact-rich tasks. The results indicate that the proposed method can be implemented in various contact-rich manipulations. A demonstration video shows the performance. (https://youtu.be/gxSCl7Tp4-0)
