近年来,提升机器人与人类交互的自然性和直观性成为研究热点。实现这一目标的关键挑战在于使系统能够以类人方式操作物体与工具。本文提出一种新方法HMAMP,利用对抗性运动先验学习人类风格的操作技能。该方法通过对抗网络建模工具与物体操作的复杂动态及任务目标,判别器结合真实数据与代理在模拟中执行的数据进行训练,旨在优化策略以生成符合人类运动统计特性的轨迹。我们在一个高难度操作任务——钉钉上评估了HMAMP,结果表明其学习到的操作技能优于现有基线方法。此外,我们通过真实机械臂完成了钉钉任务,验证了该方法在现实场景中的潜力。总体而言,HMAMP为开发能以类人方式与人类互动的机器人系统提供了重要进展。
原文摘要 · Abstract (English)
In recent years, there has been growing interest in developing robots and autonomous systems that can interact with human in a more natural and intuitive way. One of the key challenges in achieving this goal is to enable these systems to manipulate objects and tools in a manner that is similar to that of humans. In this paper, we propose a novel approach for learning human-style manipulation skills by using adversarial motion priors, which we name HMAMP. The approach leverages adversarial networks to model the complex dynamics of tool and object manipulation, as well as the aim of the manipulation task. The discriminator is trained using a combination of real-world data and simulation data executed by the agent, which is designed to train a policy that generates realistic motion trajectories that match the statistical properties of human motion. We evaluated HMAMP on one challenging manipulation task: hammering, and the results indicate that HMAMP is capable of learning human-style manipulation skills that outperform current baseline methods. Additionally, we demonstrate that HMAMP has potential for real-world applications by performing real robot arm hammering tasks. In general, HMAMP represents a significant step towards developing robots and autonomous systems that can interact with humans in a more natural and intuitive way, by learning to manipulate tools and objects in a manner similar to how humans do.
