AI 中文摘要
可控性是通用机器人策略的一项关键能力,但在灵巧手系统中却普遍缺失,因为缺乏大规模、语言对齐且动作准确的示范数据。为解决这一瓶颈,我们提出了一个全栈系统,该系统能从第一人称人类视频扩展灵巧VLA预训练,并实现数据高效的真实机器人后训练。它集成了EgoSmith数据管道,一个统一的机器人堆栈以及EgoSteer。人类数据预训练为EgoSteer配备了语言引导的操作先验知识,通过机器人后训练和DAgger优化得到强化。实验表明,EgoSteer能在40多个不同任务中稳健执行自由形式指令,预训练模型还能少样本适应复杂的长期任务。我们开源了系统、数据和模型。
英文摘要
The enduring vision of general-purpose robots serving humanity hinges fundamentally on policy steerability. However, prevailing paradigms of learning from expert demonstrations demand massive real-world data even on simplified grippers, rendering them prohibitively expensive for high-dimensional, data-scarce dexterous hands. To overcome this bottleneck, we present a full-stack system that scales dexterous VLA pre-training from egocentric human videos and enables data-efficient real-robot post-training. It integrates EgoSmith, a data pipeline that curates in-the-wild egocentric videos into 9,606 hours of pre-training data with 8.3x higher throughput and better accuracy than prior SOTA; a unified Robot Stack for teleoperation and human-in-the-loop correction tailored for dexterous hands; and EgoSteer, a world-model-enhanced VLA operating on a morphology-aligned action space. Human data pre-training equips EgoSteer with language-guided manipulation priors, which are grounded through robot post-training and further refined via DAgger. Empirically, EgoSteer robustly executes free-form instructions across 45 diverse tasks, demonstrating adherence to user intent amid multiple candidate tasks and generalization. The pre-trained model also few-shot adapts to five complex long-horizon tasks, including box folding, on two embodiments with 79% average progress. All system code, datasets, model checkpoints, and an evaluation gallery are publicly available at https://egosteer.github.io/.
