Hugging Face
Hugging Face's open-source 3D-printed bipedal robot for AI learning research
LeRobot Humanoid (May 21, 2026) is a fully open-source bipedal humanoid robot platform buildable for ~$2,500 from 3D-printed parts and off-the-shelf electronics. It ships as a complete stack: assembly docs, runtime control code, system identification scripts, and MuJoCo/Isaac simulation environments — enabling the full research loop of print → simulate → collect data → train → deploy. Part of the Apache 2.0 LeRobot ecosystem alongside SO-ARM100 arms and OpenArm. **Step-by-step:** 1) `git clone https://github.com/huggingface/lerobot`. 2) Follow assembly guide at huggingface.co/blog/lerobot-humanoid. 3) 3D-print all parts from the STL files in the repo. 4) Source electronics per the BOM (motors, controllers, IMU). 5) Flash runtime and run system identification. 6) Train policies in MuJoCo sim before real-world deployment. **Best for:** robotics research, sim-to-real policy transfer, academic labs, maker community.
Build a real bipedal humanoid robot for $2,500 with a full open-source AI training stack.
