摘要:

自动装配在工业中有着广泛的应用。传统的装配任务利用预定义的轨迹或调整的力控制参数,这使得自动装配耗时,难以推广,并且对不确定性不鲁棒。在本文中,我们提出了一个高精度工业装配的学习框架。该框架结合了监督学习和强化学习。有监督学习利用轨迹优化为策略提供初始指导,而强化学习利用actor-critic算法在监督者不准确的情况下建立评价体系。与强化学习相比,该学习框架具有更高的效率,并且比监督学习具有更好的稳定性。仿真和实验均验证了该方法的有效性。

英文摘要:

Automatic assembly has broad applications in industries. Traditional assembly tasks utilize predefined trajectories or tuned force control parameters, which make the automatic assembly time-consuming, difficult to generalize, and not robust to uncertainties. In this paper, we propose a learning framework for high precision industrial assembly. The framework combines both the supervised learning and the reinforcement learning. The supervised learning utilizes trajectory optimization to provide the initial guidance to the policy, while the reinforcement learning utilizes actor-critic algorithm to establish the evaluation system even the supervisor is not accurate. The proposed learning framework is more efficient compared with the reinforcement learning and achieves better stability performance than the supervised learning. The effectiveness of the method is verified by both the simulation and experiment.
