A Giant Leap in Open-Source Robotics

Reachy 2 is more than an upgrade—it represents a shift in the philosophy of human-robot interaction. As a fully open-source AI humanoid, Reachy 2 empowers developers, educators, and institutions to create, test, and iterate robotic behaviours with complete transparency.

Unlike proprietary robots that restrict access to source code and hardware configurations, Reachy 2 delivers full openness in its:

• Mechanical design
  
• Electronics schematics
  
• AI models
  
• Control software
  

This transparency opens innovation at every level, allowing global collaboration and customisation for specific research and application needs.

Sleek New Design Meets Functional Excellence

Reachy 2 flaunts a modular, biomimetic design inspired by the human form. It includes:

• Two articulated 7-DoF (Degrees of Freedom) arms with advanced precision
  
• A responsive torso with 2 DoF for fluid movement
  
• Expressive head and neck with stereo vision and audio localisation
  
• A high-resolution facial display for conveying emotions and improving communication
  

This design isn’t just aesthetic—it’s practical. The arms and torso offer lifelike mobility, allowing Reachy 2 to perform nuanced tasks like manipulating delicate objects or interacting with people in collaborative environments.

AI-Powered Perception and Decision-Making

The core strength of Reachy 2 lies in its AI integration. Leveraging the latest edge computing and neural networks, it processes real-time data from its environment using:

• Stereo cameras for 3D depth perception
  
• Microphone arrays for sound detection and directional hearing
  
• Force and tactile sensors embedded in the arms and fingers
  

Thanks to these inputs, Reachy 2 can understand complex human commands, navigate unpredictable environments, and perform tasks with context-aware intelligence.

Its AI brain can be trained and fine-tuned via popular machine learning platforms like TensorFlow, PyTorch, and ROS2 (Robot Operating System 2). Moreover, it supports plug-and-play integration with LLM-powered modules such as GPT-based assistants, enabling robust natural language processing capabilities.

Advanced Dexterity for Real-World Applications

Reachy 2’s improved hands and arms are designed for real-world utility, capable of gripping, lifting, rotating, and sensing the objects they hold. Each limb features:

• Precision motor control with smooth actuation
  
• Torque sensors for grip force management
  
• Modular hand attachments for specific use-cases (e.g., surgical tools, mechanical grips, educational manipulatives)
  

This makes it ideal for:

• Laboratory automation
  
• Assistive technology in healthcare
  
• Customer-facing roles in service industries
  
• Educational environments for robotics and AI learning
  

Plug-and-Play Development Environment

Reachy 2 is engineered to drastically reduce the development curve for robotics enthusiasts and experts alike. It comes pre-configured with:

• Python SDKs
  
• ROS 2 nodes
  
• Simulation environments using Gazebo and Unity
  
• Cloud-based dashboard for remote control and monitoring
  

With these tools, users can simulate scenarios before deploying them on the physical robot, which reduces errors, cost, and time in R&D.

Its open APIs and modular architecture also allow seamless integration with third-party sensors, actuators, and even AI agents like voice assistants or image classifiers.

Unparalleled Open-Source Community Support

Pollen Robotics has cultivated a thriving community around Reachy. Developers, researchers, and students worldwide contribute enhancements, share projects, and assist through:

• GitHub repositories
  
• Online forums
  
• Workshops and conferences
  
• Collaborative publications and research papers
  

The open-source ethos ensures that Reachy 2 continuously evolves and improves, becoming smarter, more adaptable, and more useful with every shared contribution.

A Humanoid Robot That Respects Ethical AI Design

Reachy 2 is built with ethical AI guidelines in mind, ensuring responsible use in both public and private domains. Features include:

• Privacy-first design, with control over data sharing and processing
  
• User-consent systems before initiating recording or interaction
  
• Bias mitigation mechanisms within AI processing pipelines
  

Its transparency and respect for ethical standards make it the preferred choice for institutions seeking to test or deploy responsible robotics solutions.
