FARM让机器人在剧烈动作中更稳定,同时保持日常动作的高精度。

FARM: Frame-Accelerated Augmentation and Residual Mixture-of-Experts for Physics-Based High-Dynamic Humanoid Control

  • 通过加速帧间变化增强模型对高速动作的适应能力
  • 在自建数据集上降低42.8%失败率,位置误差减少14.6%
  • 适合需要高动态控制的机器人与动画场景

统一的物理驱动类人机器人控制器在机器人与角色动画中至关重要,但现有模型在平缓动作上表现良好,却难以应对爆发性动作,限制了实际应用。本文提出FARM(帧加速增强与残差专家混合模型),一个端到端框架,包含帧加速增强、稳健基线控制器和残差专家混合模型(MoE)。帧加速增强通过拉大帧间间隔,使模型暴露于高速姿态变化。基线控制器精准追踪日常低动态动作,而残差MoE则动态分配额外网络容量以应对高动态挑战,显著提升追踪精度。由于缺乏公开基准,我们构建了首个高动态类人动作数据集HDHM,包含3593段物理合理动作片段。在该数据集上,FARM相比基线将追踪失败率降低42.8%,全局每关节位置误差相对减少14.6%,同时保持对低动态动作的近乎完美精度。该成果确立了高动态类人控制新基准,并首次推出专用开放评测集。代码与数据集将开源至https://github.com/Colin-Jing/FARM。

原文摘要 · Abstract (English)

Unified physics-based humanoid controllers are pivotal for robotics and character animation, yet models that excel on gentle, everyday motions still stumble on explosive actions, hampering real-world deployment. We bridge this gap with FARM (Frame-Accelerated Augmentation and Residual Mixture-of-Experts), an end-to-end framework composed of frame-accelerated augmentation, a robust base controller, and a residual mixture-of-experts (MoE). Frame-accelerated augmentation exposes the model to high-velocity pose changes by widening inter-frame gaps. The base controller reliably tracks everyday low-dynamic motions, while the residual MoE adaptively allocates additional network capacity to handle challenging high-dynamic actions, significantly enhancing tracking accuracy. In the absence of a public benchmark, we curate the High-Dynamic Humanoid Motion (HDHM) dataset, comprising 3593 physically plausible clips. On HDHM, FARM reduces the tracking failure rate by 42.8\% and lowers global mean per-joint position error by 14.6\% relative to the baseline, while preserving near-perfect accuracy on low-dynamic motions. These results establish FARM as a new baseline for high-dynamic humanoid control and introduce the first open benchmark dedicated to this challenge. The code and dataset will be released at https://github.com/Colin-Jing/FARM.
