This first rover I built.

This rover is built from an outreach rover developed by ESA and provides a very simple introduction and starting point.

Marvin, development name Hugs, is an ExoMy rover. He is a fully 3D-printed rover inspired by ExoMars. ExoMy's hardware and software is fully open source and extensive building and assembly instructions are available for the rover. Both were originally provided by the European Space Agency, though this has been archived, and is now maintained by 0xD0M1M0 on GitHub.

A few alterations to the power subsystem were made compared to the source. The battery was swapped from a 3S 3000mAh LiPo to a NiMH battery. This simplifies charging and safety, though substantially increases mass.
