Lerobot, a pioneering open-source platform for robot learning, has announced its latest major update, Lerobot v0.4.0. This groundbreaking release brings together numerous significant advancements that are poised to transform the field of open-source robotics.
At the forefront of this update is the revamped dataset infrastructure, dubbed LeRobotDataset v3.0. The new format, which supports massive scale (> 400GB), enables unprecedented scalability and efficiency in handling large datasets such as OXE (Open X Embodiment) and Droid. Furthermore, this upgrade introduces a suite of powerful utilities for flexible dataset editing, including the ability to delete specific episodes, split datasets by fractions or episode indices, add or remove features with ease, and merge multiple datasets into one unified set.
Moreover, LeRobot v0.4.0 expands its simulation capabilities by supporting LIBERO, one of the largest open benchmarks for Vision-Language-Action (VLA) policies, boasting over 130 tasks. This integration marks a significant step toward building the go-to evaluation hub for VLAs, providing an effortless setup for evaluating any VLA policy. Additionally, LeRobot now officially supports Meta-World, a premier benchmark for testing multi-task and generalization abilities in robotic manipulation, featuring over 50 diverse manipulation tasks.
Another key feature of this update is the introduction of Processors: a new, modular pipeline that acts as a universal translator for data. This powerful tool enables the seamless integration of robot hardware with AI models by normalizing, tokenizing text, moving data to the GPU, and handling batched tensors. Two distinct types of processors - PolicyProcessorPipeline and RobotProcessorPipeline - make it simple to connect any policy to any robot, ensuring your data is always in the perfect format for every step of the way.
The recent integration of NVIDIA's GR00T N1.5 into LeRobot further solidifies its position as a leader in open-source robotics. This cross-embodiment model excels at generalized reasoning and manipulation tasks with improved language-following ability. Moreover, it learns from an expansive dataset combining real captured humanoid data, synthetic data generated by NVIDIA Isaac GR00T Blueprint, and internet-scale video data.
In addition to these significant advancements, LeRobot v0.4.0 boasts numerous bug fixes, documentation improvements, updated dependencies, more examples, and better infrastructure to make the user experience smoother and more reliable. The team expresses their gratitude towards everyone in the community for their invaluable contributions, feedback, and support.
Overall, Lerobot v0.4.0 represents a significant leap forward in open-source robotics. With its powerful new features, enhanced dataset capabilities, and streamlined pipeline system, this release has the potential to revolutionize the field of embodied AI research. As LeRobot continues to evolve, it is poised to unlock new possibilities for robot learning, making it an essential platform for researchers, developers, and enthusiasts alike.
