Pollen Robotics Reachy 2 166cm Open-Source 7-DoF Orbita-Arm & LeRobot VLA Mobile Humanoid
166cm, 50kg open-source mobile manipulation humanoid built by Pollen Robotics (now part of Hugging Face), featuring dual 7-DoF bio-inspired arms driven by patented Orbita 3D ball-joint actuators (3kg payload), a 3-omniwheel LiDAR base, dual global-shutter stereo head cameras, and native ROS 2 / Rust / LeRobot VLA integration.
Editorial Rating Methodology (★ 4.9 / 5.0): This score is an internal editorial evaluation compiled by the RECIWO Labs editorial team—not a user poll or crowd-voted rating. It assesses published silicon compute efficiency (25%), optical/sensor/actuator engineering (25%), battery & thermal envelope (20%), SDK/software openness (15%), and price-to-specification value (15%) based on official manufacturer datasheets and public technical documentation.

Key Engineering Highlights
- Replaces bulky serial servo stacks in the neck, shoulders, and wrists with Pollen's patented Orbita 2D and Orbita 3D parallel ball-joint actuators—routing cables cleanly through hollow centers while mimicking fluid human joint kinematics
- Purpose-built as the flagship full-scale hardware reference platform for Hugging Face's LeRobot ecosystem—enabling 1:1 immersive VR teleoperation (Quest 3 / Vision Pro) and seamless collection of bimanual VLA training datasets
- Combines dual 7-DoF compliant arms (3kg continuous payload per arm) and an adjustable 136–166cm torso with a 3-omniwheel LiDAR base running 100% open-source ROS 2 Humble, Rust low-level control, and Python APIs
