What is Reachy 2?
Reachy 2 is Pollen Robotics' research humanoid, built for manipulation and VR teleoperation; Pollen joined Hugging Face in 2025. It has two 7-DoF arms, a 3-DoF neck, parallel grippers and an optional omnidirectional base.
Its joints use Pollen's Orbita parallel actuators: Orbita 2D for shoulders and elbows, Orbita 3D for wrists and neck. The head carries stereo global-shutter cameras plus depth, and an Orbbec RGB-D camera in the torso watches the workspace.
Openness is partial. The SDK, simulation assets, docs and control-board PCBs are Apache-2.0, but the mechanical CAD isn't published, so you can't build one from the repo.
