Publisher review
Reachy 2, developed by Pollen Robotics (acquired by Hugging Face in April 2025), is a fully open-source bimanual mobile manipulator humanoid robot purpose-built for embodied AI research, academic education, and real-world applications. It targets AI and robotics labs seeking a customizable platform for object manipulation, navigation, and human-robot interaction studies. The robot's modular design allows configuration as a dual-arm or single-arm system, with or without an omnidirectional mobile base, making it adaptable to diverse experimental setups. Its open-source nature, supported by a Python SDK and ROS2 Humble middleware, enables deep customization and community-driven improvements, positioning it as a tool for prototyping advanced AI behaviors rather than a consumer product.
Reachy 2 integrates advanced hardware for immersive teleoperation and autonomous operation. Each arm has 7 degrees of freedom (DOF) with bio-inspired kinematics, capable of lifting objects up to 3 kg, and features a parallel torque-controlled gripper for dexterous manipulation. The head is animated by the proprietary Orbita system, with two RGB cameras for vision and a Luxonis OAK-FFC ToF 3D sensor for depth measurement, while the torso houses an Orbecc Gemini 336 RGB-D camera and a custom audio system with high-quality speakers and a microphone array. The omnidirectional base uses three omniwheels and a LiDAR for navigation. VR teleoperation is supported with 3D vision and spatialized audio, enabling remote control of arms, hands, and head. The system runs on an onboard CPU for machine learning workloads, compatible with modern AI frameworks.
In the open-source humanoid robot market, Reachy 2 competes with platforms like Unitree's H1 and Fourier Intelligence's GR-1, but distinguishes itself through its focus on bimanual manipulation and expressive interaction rather than full-body locomotion. At $70,000 for a dual-arm mobile base configuration, it is priced significantly lower than research-grade robots like Boston Dynamics' Spot (starting at $74,500 without arms) or AgileX's Bunker, but higher than hobbyist kits like the InMoov. Its acquisition by Hugging Face in April 2025 signals a strategic push to integrate large language models and AI frameworks directly into robotic platforms, potentially accelerating adoption in AI research communities.
Key trade-offs include the high upfront cost of $70,000, which may exclude individual researchers and students. The use of Dynamixel motors in some components has been criticized by the community for inflating prices, though Pollen Robotics defends their reliability. Setup and maintenance require significant technical expertise in robotics, Python, and ROS2, limiting accessibility for novices. While the robot excels in manipulation and teleoperation, its mobile base lacks the rugged terrain capabilities of quadruped robots, and the CPU-based system may be underpowered for intensive deep learning training compared to GPU-equipped alternatives. The open-source ecosystem is still maturing, with limited third-party add-ons compared to more established platforms like ROS Industrial.

Order a Reachy 2 configuration
Contact Pollen Robotics via their website to select your Reachy 2 configuration (e.g., dual-arm mobile base). Provide your lab or institution details and arrange payment. The base price starts at $70,000; expect a purchase order or invoice process.
-
Set up the robot hardware
Unpack Reachy 2 and assemble the arms, head, and base per the included manual. Connect power and network cables. Ensure the robot is on a stable, flat surface with adequate space for movement and manipulation testing.
-
Install Python SDK and ROS2
On your development computer, install Python 3.8+ and ROS2 Humble. Clone the Reachy 2 SDK repository from GitHub. Run the provided setup script to install dependencies and configure the environment for robot communication.
-
Calibrate sensors and actuators
Power on Reachy 2 and connect via the SDK. Run the calibration routine for each arm's joints, gripper, and head motors. Verify the RGB cameras, ToF sensor, and LiDAR return accurate data by checking sample outputs.
