A tutorial note on collecting simulated data for vision-language-action models
- 用PyBullet生成定制化仿真数据，灵活控制环境
- 通过LIBERO标准化任务，提升模型评估一致性
- 适合机器人、AI训练等方向的研究者参考
传统机器人系统将智能拆分为计算机视觉、自然语言处理和运动控制等独立模块。视觉-语言-动作（VLA）模型则通过单一神经网络，同时处理视觉观测、理解人类指令并直接输出机器人动作，实现统一框架。但这类系统高度依赖高质量训练数据，以捕捉视觉、语言与动作之间的复杂关系。本文综述三种代表性系统：用于灵活定制数据生成的PyBullet仿真框架、用于标准化任务定义与评估的LIBERO基准套件，以及用于大规模多机器人数据采集的RT-X数据集。文中展示了在PyBullet中生成数据的方法，在LIBERO中进行定制化数据收集，并概述了RT-X数据集在大规模多机器人数据获取中的特点与作用。
原文摘要 · Abstract (English)
Traditional robotic systems typically decompose intelligence into independent modules for computer vision, natural language processing, and motion control. Vision-Language-Action (VLA) models fundamentally transform this approach by employing a single neural network that can simultaneously process visual observations, understand human instructions, and directly output robot actions -- all within a unified framework. However, these systems are highly dependent on high-quality training datasets that can capture the complex relationships between visual observations, language instructions, and robotic actions. This tutorial reviews three representative systems: the PyBullet simulation framework for flexible customized data generation, the LIBERO benchmark suite for standardized task definition and evaluation, and the RT-X dataset collection for large-scale multi-robot data acquisition. We demonstrated dataset generation approaches in PyBullet simulation and customized data collection within LIBERO, and provide an overview of the characteristics and roles of the RT-X dataset for large-scale multi-robot data acquisition.
