Summary
Reachy 2 is Pollen Robotics' open-source humanoid: a bimanual mobile manipulator with two human-scale 7-DOF arms, an expressive head and an omnidirectional mobile base. It is the reference research body for Hugging Face's open robot-learning ecosystem.
Each of Reachy 2's arms mirrors the proportions of an adult human arm and can lift up to 3 kg, driven by Pollen's Orbita actuators, while a Time-of-Flight sensor and dual RGB-D cameras provide depth perception. The robot is fully programmable in Python, runs on ROS 2, and is designed to be reproducible and extensible by the open-source community — a sharp contrast to closed industrial humanoids. Following Hugging Face's April 2025 acquisition of Pollen, Reachy 2 integrates tightly with the LeRobot framework for sharing manipulation datasets and learned policies. It sells from about $78,000 and is widely used in university and corporate AI labs for teleoperation and imitation-learning research.
