提出Human2Humanoid无监督运动重定向框架,利用CycleGAN和骨架感知图卷积网络处理未配对数据,通过形态不变末端执行器一致性损失和物理感知可行性约束,实现从人体运动到人形机器人的高保真重定向。

摘要:

将人体运动重定向到人形机器人对于远程操作、模仿学习和人机交互至关重要。然而,由于人类与机器人在骨骼拓扑、肢体比例和自由度等方面的显著形态差异,以及配对运动数据的稀缺性,这仍然具有挑战性。本文提出了Human2Humanoid,一种无监督运动重定向框架,能够将人体运动高保真地迁移到人形机器人行为。为了在未配对数据下弥合领域差距,我们采用基于CycleGAN的架构,配备骨架感知图卷积网络来捕获拓扑相关的运动特征。为了解决跨域尺度不匹配问题,我们引入了一种形态不变的末端执行器一致性损失,该损失对齐归一化的末端执行器轨迹,以保留跨实体的运动语义。为了提高物理合理性并减少接触伪影,我们施加了显式的物理感知可行性约束,以鼓励再现源运动中的接触模式。实验结果表明,所提出的方法成功地将人体运动重定向到Unitree G1人形机器人,无需配对数据,并且在下游可控性和物理可行性方面均优于现有方法。

英文摘要:

Retargeting human motion to humanoid robots is critical for teleoperation, imitation learning and human-robot interaction. However, it remains challenging because of substantial morphological discrepancies between humans and robots, including differences in skeletal topology, limb proportions and degrees of freedom, as well as the scarcity of paired motion data. This paper presents Human2Humanoid, an unsupervised motion retargeting framework that transfers human motions to humanoid robot behaviors with high fidelity. To bridge the domain gap under unpaired data, we adopt a CycleGAN-based architecture equipped with a skeleton-aware graph convolutional network to capture topology-dependent motion features. To address cross-domain scale mismatches, we introduce a morphology-invariant end-effector consistency loss that aligns normalized end-effector trajectories to preserve motion semantics across embodiments. To improve physical plausibility and reduce contact artifacts, we impose explicit physics-aware feasibility constraints to encourage reproduction of the contact patterns in the source motion. Experimental results show that the proposed method successfully retargets human motion to the Unitree G1 humanoid robot without paired data, and outperforms existing methods in both downstream controllability and physical feasibility.
