You can download everything you’ll need to make it work — including assembly instructions and software — through GitHub. The ESA estimates it will cost most people about €500 (close to $600) to purchase all the necessary materials and components to make ExoMy. It will also take around two weeks to 3D print everything. “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,” the agency explains.

If $600 is outside your budget, you can see the ExoMy in action thanks to a video the ESA shared. The agency says it hopes university students will use the design as a way to learn about robotics and the ExoMars mission.
