Vision-Language-Action in Robotics: A Survey of Datasets and Data Infrastructure
This survey paper examines the data infrastructure challenges in Vision-Language-Action (VLA) models for robotics. It categorizes datasets by embodiment diversity, modality composition, and action space formulation, identifies limitations in simulation-based and video-reconstruction paradigms, and outlines four open challenges: representation alignment, multimodal supervision, reasoning assessment, and scalable data generation.

The robotics data ecosystem keeps getting stronger 🦾
The author explores the LeRobot community dataset, using embeddings and FiftyOne to analyze 497 episodes across 50 robot types. They identify near-duplicates, filter sessions, and reveal cross-embodiment patterns like cloth folding. A curated subset is available for further exploration.

Question to resolve: Can you describe the distinct tasks and settings, and deliver consistent robot states and action definitions?
How this brief works
This rolling brief uses the latest published research, model, dataset and simulation coverage, up to 80 reports. Topic matches are reading aids. They do not prove a model used a dataset or that a buyer is purchasing data.
Collection considerations are RoboSignal’s interpretation of the cited research. They are not new findings from every linked report.
