Hugging Face LeRobot Brings Open-Source Humanoid Support to the Unitree G1
mishig25 · x · 2026-09-25
Hugging Face's LeRobot team published a blog detailing how they bring humanoids into their open-source robot learning library, building a full workflow around the Unitree G1.
Key points:
- Why humanoids need a different control stack: bipeds must balance continuously, and VLA inference is too slow to control those dynamics directly. They insert a fast controller between policy and robot: a π0.5 policy predicts compact SONIC latent motion tokens from language, robot state, and camera observations, and a fast 29-DoF whole-body controller decodes them into dynamically feasible joint targets.
- Starting from OpenHLM (Open Humanoid Loco-Manipulation), which trains OpenPI's π0.5 on whole-body G1 demonstrations.
- The post also covers other open-source humanoid hardware supported, NVIDIA SONIC integration, and how teleoperation, datasets, and policy learning connect end-to-end.
