“Anyone with a 3D printer can build their own ExoMy, at an estimated budget of €500 or less,” explains Swiss trainee Miro Voellmy. “The source code is available on GitHub along with a step-by-step assembly guide and tutorials.

“We focused on making the design as affordable and accessible as possible. It uses a Raspberry Pi computer and off-the-shelf electronic parts available online and at any hobby shop. Our hope is that school or university students will make their own ExoMy, to become familiar with robotics, and learn about the full-sized ExoMars rover, which is scheduled for launch in 2022.”
