📝 摘要(中文)

现实、快速的机器人仿真能够促进大规模的具身AI模型训练,然而现有仿真覆盖的真实任务和物理现象范围有限。创建更好的仿真需要大量专家努力,难以扩展。为此,本文提出了Gym-Anything for Robotics框架,通过编码代理创建逼真的机器人仿真。我们根据美国GDP数据选择仿真,定义良好仿真和任务的标准,并开发了对抗创建-审计循环来验证每个仿真和任务。基于此,我们构建了RoboWorld,包含25个仿真和175个训练环境。即使是最先进的模型在RoboWorld测试任务上也表现不佳,平均奖励仅为0.06。我们还提出了多种新方法来提升模型性能,包括上下文学习、特权教师指导等,显著提高了性能。我们发布了管道、RL环境和基准,以促进未来研究。

📄 摘要(原文)

Realistic, fast robotics simulations could enable large-scale training of embodied AI models that transfer to the real world. However, despite decades of progress, available simulations cover only a narrow range of real-world tasks and physical phenomena. The core bottleneck is that creating better simulations requires significant expert effort and therefore does not scale. To address this, we introduce Gym-Anything for Robotics, a framework in which coding agents create realistic robotics simulations. Our core insight is that simulation creation is a coding agent task, so improvements in coding agents translate directly into richer and more faithful simulations. We select simulations based on U.S. GDP data to cover economically valuable physical work, define what makes a good simulation and a good task, and develop an adversarial creation-audit loop that checks each simulation and task against these definitions. Using this pipeline, we build RoboWorld, a set of 25 simulations with 25 test and 175 training RL environments of varying difficulty. Even the best frontier models fail on every RoboWorld test task, achieving an average reward of only 0.06. Building on RoboWorld, we introduce several new ways for frontier models to improve, including in-context learning across repeated attempts, a privileged teacher that reads the simulator state and teaches a student in context, self-assisted learning from the model's own privileged experience, and code policies that generate demonstrations across varied scenes to train vision-language-action models (VLAs) such as $π_{0.5}$. Each of these substantially improves performance. We release our pipeline, RL environments, and benchmark to facilitate future research.
