HuggingFaceVLA/community_dataset_v1

Community Dataset v1

A large-scale community-contributed robotics dataset for vision-language-action learning, featuring 128 datasets from 55 contributors worldwide.

We used this dataset to pretrain SmolVLA. However, this is not a complete set, but the dataset that we selected using specific filters, like fps, min num of episodes, and some qualitative assessment of video qualities, using the https://huggingface.co/spaces/Beegbrain/FilterLeRobotData tool. We also manually curated the task descriptions for this subset of the dataset.

🌟 Overview

This dataset represents a collaborative effort from the robotics and AI community to build comprehensive training data for embodied AI systems. Each contribution contains demonstrations of robotic manipulation tasks with the SO100 arm, recorded using LeRobot tools, primarily focused on tabletop scenarios and everyday object interactions.
