Microrovers Catalog

Small in size, but not in capabilities, microrovers may one day play a larger role in exploring other worlds. In partnership with Cornell University, and funded in part by NASA, the Planetary Society is investigating the future role of microrovers in solar system exploration.
We've compiled a catalog of known microrovers that have already been built or designed, ranging in use from military applications to planetary exploration. However, only one rover that has actually visited another world - Sojourner (part of the 1997 Mars Pathfinder mission) - is small enough to be considered a microrover.

Microrovers can help clear bombs, reconnoiter dangerous territory, inspect pipes, or examine rocks on an alien planet. This catalog will serve as a single public location to showcase microrover technology in all its variety, a starting point to see what work has been done before embarking on new design projects.

When is a rover considered "micro"? While there is no precise definition for the size of a microrover, for the purpose of this catalog, the Planetary Society defines them as rovers with a mass of approximately 1 to 12 kilograms.  To put it another way, they range is size from MUSES-CN (1 kg) to Sojourner (11.5 kg).  However, this list also includes rovers up to 100 kg, both as a basis of comparison and because those larger rovers may still help inspire the design of new planetary microrovers.
