What is lerobot-humanoid?

LeRobot Humanoid Workspace is not a single piece of software but an umbrella project that ties together everything needed to build a real, physical humanoid robot, from the initial mechanical design all the way to running it. It groups five separate repositories into one workspace so a person can see the whole project at a glance, even though each folder is its own independent Git project with its own history. The stated goal is an open, practical, low cost humanoid robot that other people can actually reproduce, with a hardware cost target under 5,000 US dollars before shipping and taxes. The design favors a lightweight structure, parts that can be 3D printed at home, and a build process documented well enough that someone else could follow it from scratch, all the way to a reproducible research setup. The five sub-repositories cover different stages of the process. The design repository handles mechanical and control co-design, defining the robot's geometry and testing whether control ideas are feasible before committing to hardware. The hardware repository is the practical build guide: the bill of materials, printable part files, wiring, and instructions for assembling and commissioning the motors. The model repository holds shared robot description files and constants that the other parts of the project import. The runtime repository is what actually makes the robot move, in simulation or on the real machine, including calibration and running control policies, and it connects into the wider LeRobot software ecosystem. Finally, the identification repository takes data recorded from the real robot and uses it to tune the accuracy of the simulator. These pieces are meant to work in a loop: design choices lead to a model, the model is validated through simulation and real runtime testing, real world logs are used to refine the simulation, and the improved parameters feed back into the design and runtime again. This project is aimed at robotics engineers, hobbyists, and researchers comfortable working across mechanical design, 3D printing, and control software, rather than casual hobby coders.
