Platform supplies hardware designs, software, and simulation tools for full robot development cycle.

We built a bipedal robot for about $2,500.
A real, mostly 3D-printed robot you can build, repair, simulate, train, and control.
Today we’re releasing LeRobot Humanoid: an open robot-learning platform with hardware, runtime, identification tools, and training environments.

Users are excited about the $2,500 open-source LeRobot bipedal humanoid robot because its low price and accessibility could democratize robotics research and hands-on tinkering.

Imagine this thing running at you full speed, except it's upper body is just a tnt crate

Hugging Face just released LeRobot Humanoid
An open-source, low-cost (~$2.5k), 3D-printed humanoid built for robot learning and not just demos.
What’s cool is it’s a full stack release: • hardware + CAD • runtime & calibration • sim environments • identification tools • training zoo for locomotion Designed so anyone can build, break, repair, simulate, and train on a real humanoid.
Another win for open-source robotics! 🔥
@huggingface just released a fully open-source humanoid robot, and you can build one for $2,500.
I'm a huge advocate of open-source in robotics space.
Why? Robotics is too hard to solve alone. So lowering the entry point is crucial. Also, ROS proved open ecosystems create lasting industry standards.
So let's have a look at the new member of humanoids family!
@LeRobotHF Humanoid is a 3D-printed, bipedal humanoid platform designed for real robot learning experiments.
It's a complete and, buildable robot
Anddddd yes, it's a full stack release:
→ Hardware files, bill of materials and full assembly documentation → Simulation assets and training environments → Runtime tools for calibration and real-world control → Sim-to-real identification pipeline
When a part breaks, reprint it. When a design choice doesn't work, modify it and test again.
The whole point is fast iteration on real hardware, not treating the robot as a fixed artefact.
The timing is not a coincidence. As foundation models for robotics mature, the field desperately needs open physical platforms to train, validate and deploy them on.
@ClementDelangue LET'S GO!!!

@huggingface's @LeRobotHF team announced LeRobot Humanoid, an open-source bipedal robot platform built for roughly $2,500 using mostly 3D-printed and off-the-shelf parts:
The release provides complete hardware designs, runtime software, identification tools, simulation environments, and training pipelines to support building, repairing, simulating, training, and controlling the robot.
The video they released today shows the red biped performing hardware arm tests, squat leg motions, and sim-to-real walking policy transfer while suspended, demonstrating practical viability for robot learning.

Another cheap do-it-yourself humanoid (well, pair of legs, for now)

@LeRobotHF Very cool but is there a discussion of how the motors were selected and how their positioning on the limbs was decided?
The most important part of LeRobot Humanoid isn’t just the robot — it’s the closed learning loop.
design → simulation → data collection → system identification → policy training → real robot deployment
This is the kind of open infrastructure robotics has been missing for years.
Huge step for accessible humanoid research 🚀

Yes, exactly, the design repo gives more details. In short: actuator selection came from choosing the RobStride ecosystem and a preliminary study of the required joint torques, while actuator placement emerged from the co-design process, where morphology, placement and control are evaluated jointly. https://github.com/Virgileboat/lerobot-humanoid-design
@yacineMTB why would the legs be better than flying for a bomb? i feel like the walking versions of these will be gun platforms
@LeRobotHF @_lilkm_ Next I can train my robot to walk around the room and pick up ducks!
@LeRobotHF Just read through the blog. Love the idea of having the entire process segmented out and covered. Soon as I have some space this will have to go on the build list :)
@LeRobotHF Wow~
@LeRobotHF Repairable is the part that got me. So many robot demos feel sealed off. This feels buildable, which is rare.
@LeRobotHF This is awesome! When will you create the top half?
@LeRobotHF @kneeovertoesguy thoughts?
@LeRobotHF @huggingface Based on your experience, could this be scaled down to a miniaturized version — or do small-scale actuators/batteries become the hard bottleneck?
@chris_j_paxton Because it would be funny
@LeRobotHF @robograffiti What do you think? @shiba_8ro
