Hi everyone,

![gene1-deepblue-small](https://us1.discourse-cdn.com/flex022/uploads/ros/original/3X/2/1/210ddf5285e4182d8cb034e7adf22a46c15fb892.gif)

After more than two years of internal development at Pollen Robotics, we’re releasing the complete **Reachy 2 software environment under an open-source licence**.

While the hardware is aimed at R&D budgets, we wanted the software to be accessible to the community.

[List of hardware and software specs (PDF)](https://www.pollen-robotics.com/wp-content/uploads/2025/02/Reachy2-Dual-arms-with-mobile-base-Datasheet-1.pdf)

The easiest way to test the stack is using the “One line Docker install” here:

> **[pollenrobotics/reachy2 - Docker Image](https://hub.docker.com/r/pollenrobotics/reachy2)**

👉 **Docs & SDK intro:**

> **[SDK Introduction](https://docs.pollen-robotics.com/developing-with-reachy-2/sdk-introduction/discover-sdk/)**
>
> How to easily develop using Reachy 2 with Python

I’d say this stack is meant to handle 3 main use cases:

1. **Teleoperation** (works in simulation too)
2. **Coding autonomous behaviours**
3. **Data collection** for AI training

### 🔹 What’s inside

- **ROS 2 Humble** middleware (ros2\_control, TFs, state publishers, lots of nodes)
- **Low-level control in Rust**
- **Python SDK** (`pip install reachy2-sdk`) for high-level control & demos
- **Gazebo** simulation _(MuJoCo support coming soon)_

_(Ask if you need details—didn’t want to spam the thread with the full package list.)_

Feel free to reply here or open issues/PRs on [GitHub](https://github.com/pollen-robotics). I can also recommend some “fun” things to try with the stack like:

- Trying out the [Blender integration](https://github.com/pollen-robotics/reachy2-blender)
- Playing with [Reachy’s emotions](https://github.com/pollen-robotics/reachy2_emotions)
- Learning about our [symbolic IK solver](https://github.com/pollen-robotics/reachy2_symbolic_ik)

And more.

Thanks for taking a look!

Remi
