摘要:

这是一个巨大的挑战,虽然有前途,协调集体机器人狩猎逃避者在一个分散的方式纯粹根据当地的观察。在本文中,这一挑战是解决了一种新的混合协同追踪算法,结合强化学习与人工势场法。在该算法中,分散的深度强化学习是用来学习合作的追求政策,是适应动态环境。将人工势场法作为预定义规则融入到学习过程中,提高了数据效率和泛化能力。数值仿真结果表明,所提出的混合设计优于香草强化学习或势场法设计的追求策略。此外,通过将学习到的追踪策略转移到现实世界的移动机器人中进行实验。实验结果表明,该算法在学习多个合作追捕策略的可行性和潜力。

英文摘要:

It is of great challenge, though promising, to coordinate collective robots for hunting an evader in a decentralized manner purely in light of local observations. In this paper, this challenge is addressed by a novel hybrid cooperative pursuit algorithm that combines reinforcement learning with the artificial potential field method. In the proposed algorithm, decentralized deep reinforcement learning is employed to learn cooperative pursuit policies that are adaptive to dynamic environments. The artificial potential field method is integrated into the learning process as predefined rules to improve the data efficiency and generalization ability. It is shown by numerical simulations that the proposed hybrid design outperforms the pursuit policies either learned from vanilla reinforcement learning or designed by the potential field method. Furthermore, experiments are conducted by transferring the learned pursuit policies into real-world mobile robots. Experimental results demonstrate the feasibility and potential of the proposed algorithm in learning multiple cooperative pursuit strategies.
