无线扩展现实(XR)遥操作为人形机器人示范数据采集提供具身交互能力,但高频动作传输带来的高开销限制了其大规模应用。本文构建一个集成采样、传输、插值与重建的系统框架,提出一种通信速率优化方法,通过维度级采样率调控,在保证机器人运动轨迹重建精度的前提下最小化通信能耗。由于真实物理机器人实时反馈受限于硬件成本,需通过模拟环境结合离线真实域数据校正来解决。为指导模拟到真实迁移,我们提供基于PAC-Bayes的泛化分析,揭示潜在密度比估计、有限样本偏差和编码器偏置的影响。基于此,提出一种带密度比加权和信任域正则化的近端策略优化(PPO)方法。在公开人形机器人遥操作数据集上的实验表明,该方法在模拟到真实分布偏移下显著改善了重建误差与通信能耗的权衡。进一步分析显示,算法在多种无线信道及动态运动轨迹下均具有效性。

原文摘要 · Abstract (English)

Wireless extended reality (XR) teleoperation provides embodied interaction capability for collecting humanoid robot demonstrations, but the large-scale adoption is restricted by the overhead of high-frequency motion transmission. This paper develops a system framework that integrates sampling, transmission, interpolation, and reconstruction and formulates a communication-rate optimization that aims to minimize the communication energy while maintaining the reconstruction accuracy of robot motion trajectories through dimension-wise sampling-rate control. Since acquiring real-time feedback from physical robots is limited by hardware costs, it is necessary to solve the problem through simulator interaction with offline real-domain data correction. To guide sim-to-real adaptation, we provide a PAC-Bayes generalization characterization that reveals the effects of latent density-ratio estimation, finite-sample deviation, and encoder bias. Building on this analysis, we propose a proximal policy optimization (PPO) method with density-ratio weighting and trust-region regularization. Experiments on public humanoid teleoperation dataset show that the proposed method improves the tradeoff between reconstruction error and communication energy consumption under sim-to-real distribution shift. We further analyze the effectiveness of the proposed algorithm across various wireless channels and dynamic motion trajectories.
