The European Space Agency’s (ESA) Rosalind Franklin ExoMars rover now has a miniature counterpart that you can 3D print at home, called ExoMy. All of the blueprints and software for this rover can be downloaded for free so that anyone with access to a 3D printer can assemble and program their own ExoMy. When built, it stands 42cm high and reproduces many key features of its 2m tall ExoMars, including a drill, solar panels across its back wings and a camera mast. Read more for a video, additional pictures and information.



It also features Rosalind Franklin’s ‘triple-bogie’ suspension design that enables it to cross high obstacles as high as its own wheel, while also keeping them stable on the ground. Each one of its wheels has its own motor, and their tread boasts protrusions to assist traction over rough ground. To steer the rover, you use a gamepad or web browser on a mobile device.

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,” said Swiss trainee Miro Voellmy.
