It is a small, open-source robot. You can program it with Python and change it. It works well for AI research, teaching, or trying out real-world automation ideas.

What Is Reachy Mini?

Reachy Mini is an AI robotics kit. It is for people who want serious robot features in a small, cheap, and open-source package. This small desktop robot has a 3-degree-of-freedom (DOF) arm, a gripper, and a high-resolution camera. We made Reachy Mini for testing things in computer vision, natural language processing, and human-robot interaction (HRI). A Raspberry Pi 4 controls it. This means it runs a full Linux system with Wi-Fi, USB, and GPIO pin connections. It is good for AI tasks.

What makes Reachy Mini different is how easy it is to use. You can plug it in and start. If you are making a smart assistant, looking at how robots move, or building AI prototypes, this robot is ready for serious testing right away.

Key Features:

3 DOF robotic arm with a gripper already built in
High-res RGB camera for computer vision in real-time
Raspberry Pi 4 brain for good processing and connections
Full Python libraries to write code for control and AI parts

Reachy Mini is also made of parts that can be changed. This lets developers add to, swap, or use components in new ways to make their own robot setups.

Why Open Source Matters in Modern Robotics

Open source changed software making, and it is doing the same for hardware. This is true for robots, which get better from quick testing and changes. Reachy Mini is completely open source. This includes its 3D-printable parts, its control software, and its AI setup. Being open brings many good things. These are especially helpful for schools, research labs, and new companies:

Speeds up new ideas: Developers and researchers can quickly change, share, or grow projects. This makes R&D cycles shorter.
Saves money: Schools can avoid costly license fees and being stuck with one company's hardware.
Can be changed: Engineers can fully change and add to how it works. This is key for research teams with specific needs.
Makes things equal: Open robotics helps everyone have access, even groups and schools with fewer resources.

📊 A study from IEEE found that open-source robotics tools made prototyping timelines 25% shorter in schools (Murphy et al., 2023). This is very important for educators and new companies who need to go from idea to working product quickly.

Platforms like Reachy Mini encourage a development style run by a community. This is like how Linux and Arduino became very successful.
