LeRobot Community Dataset: Curate 50 Embodiments in FiftyOne
Blog post from Voxel51
Voxel51 describes using FiftyOne Skills to curate a balanced subset of Hugging Face’s approximately 900 GB LeRobot community dataset, which contains 1,755 contributor datasets spanning 50 robot embodiments. An AI agent scanned metadata, selected up to 10 episodes per embodiment, downloaded only required video and Parquet shards, and created a 497-episode FiftyOne dataset with episode-level metadata and media references rather than copied pixel data. Each episode was embedded with Qwen3-VL-Embedding-2B, enabling similarity search, UMAP visualization, uniqueness and representativeness scoring, and text-to-video retrieval across different robot types. The analysis found that many clips were near-duplicates because the sampled episodes often came from the same recording sessions, while unusually high uniqueness scores frequently identified very short or broken recordings, illustrating the need to combine embedding-based metrics with duration and quality checks. The dataset includes 75 saved views for robot types, tasks, frame rates, and curation goals, and curated subsets can be exported as separate LeRobot v3 repositories by source dataset for policy training.
