SDK Introduction

How to easily develop with Reachy 2 using Python

🧑‍💻 Welcome to the Reachy 2 SDK

The Reachy 2 SDK is the easiest and most intuitive way to program behaviors for your Reachy 2 robot.

It’s built to help you:

  • control Reachy’s arms, head, gripper, and mobile base,
  • access its sensors, like cameras, lidar, and microphones,
  • and create rich, expressive, and interactive behaviors with Python.

Whether you want to perform simple movements, play sounds, track an object, or design complex human-robot interactions, the SDK gives you a high-level and accessible interface to do it all.


👤 Who is this SDK for?

  • If you’re just starting with Reachy 2, the SDK is your go-to entry point.

  • If you’re a developer, designer, educator, or researcher looking to create interactive robot behaviors—this SDK was made with you in mind.

  • And if you’re an advanced robotics user, don’t worry: Reachy 2 is powered by ROS 2 under the hood. You can always tap into the full ROS ecosystem for deeper customization, real-time communication, and integration with other systems.
