Notes on the mechanical design of the Sojourner rover

Nicolas Raynaud, February 2025

Wanting to build a fun robot mower, I studied the Sojourner rover as a base for my design. Looking at online 3D models, I fell into the rabbit hole of accuracy of historical artefact description. My goal in this document is to show the smart that JPL put in this little rover.

Marie Curie

The Marie Curie rover is a double for Sojourner, two rovers were built at the same time and the best one was selected to be sent to space. Today the Marie Curie rover is exposed at the National Air and Space Museum in DC. Most high resolution photos available are from this rover
