LeRobot v0.4.0: Supercharging OSS Robot Learning

We're thrilled to announce a series of significant advancements across LeRobot, designed to make open-source robot learning more powerful, scalable, and user-friendly than ever before! From revamped datasets to versatile editing tools, new simulation environments, and a groundbreaking plugin system for hardware, LeRobot is continuously evolving to meet the demands of cutting-edge embodied AI.

LeRobot v0.4.0 delivers a major upgrade for open-source robotics, introducing scalable Datasets v3.0, powerful new VLA models like PI0.5 and GR00T N1.5, and a new plugin system for easier hardware integration. The release also adds support for LIBERO and Meta-World simulations, simplified multi-GPU training, and a new Hugging Face Robot Learning Course.

We've completely overhauled our dataset infrastructure with LeRobotDataset v3.0 , featuring a new chunked episode format and streaming capabilities. This is a game-changer for handling massive datasets like OXE (Open X Embodiment) and Droid , bringing unparalleled efficiency and scalability.

These tools streamline your workflow, allowing you to curate and optimize your robot datasets like never before. Check out the docs for more details!

We're launching a comprehensive, self-paced, and entirely open-source course designed to make robot learning accessible to everyone! If you're curious about how real-world robots learn, this is the perfect place to start.

We've also provided a conversion script to easily migrate your existing v2.1 datasets to the new v3.0 format, ensuring a smooth transition. Read more about it in our previous blog post . Open-source robotics keeps leveling up!

This system makes it simple to connect any policy to any robot, ensuring your data is always in the perfect format for every step of the way. Learn more about it in our Introduction to Processors documentation .

We want to extend a huge thank you to everyone in the community for your invaluable contributions, feedback, and support. We're incredibly excited about the future of open-source robotics and can't wait to work with you on what's next!

Working with LeRobot datasets just got a whole lot easier! We've introduced a powerful set of utilities for flexible dataset editing.

We're continuously expanding LeRobot's simulation capabilities to provide richer and more diverse training environments for your robotic policies.

LeRobot now officially supports LIBERO , one of the largest open benchmarks for Vision-Language-Action (VLA) policies, boasting over 130 tasks! This is a huge step toward building the go-to evaluation hub for VLAs, enabling easy integration and a unified setup for evaluating any VLA policy.
