NASA/JPL has been behind the building of some of the coolest rovers ever to roll on the surface of Earth and elsewhere. Rovers will continue to be a big part of exploring our solar system and NASA wants to encourage students, hobbyists, and enthusiasts to work on rover technology. To that end, it has unveiled the JPL Open Source Rover (OSR)
OSR is a scaled down version of Curiosity that has similar 6-wheel steering and Rocker-Bogie suspension allowing it to roll over most terrain. JPL has published the design of the OSR under an open source license on GitHub allowing anyone to download the baseline instructions and test plans to build their own rover. The instructions are said to be quite detailed and to allow the builder to make their own design choices.
