Got some spare time this weekend? Why not build yourself a working rover from plans provided by NASA? The spaceniks at the Jet Propulsion Laboratory have all the plans, code, and materials for you to peruse and use — just make sure you’ve got $2,500 and a bit of engineering know-how. This thing isn’t made out of Lincoln Logs. The story is this: after Curiosity landed on Mars, JPL wanted to create something a little smaller and less complex that it could use for educational purposes. ROV-E, as they called this new rover, traveled with JPL staff throughout the country. Unsurprisingly, among the many questions asked was often whether a class or group could build one of their own. The answer, unfortunately, was no: though far less expensive and complex than a real Mars rover, ROV-E was still too expensive and complex to be a class project. So JPL engineers decided to build one that wasn’t. The result is the JPL Open Source Rover , a set of plans that mimic the key components of Curiosity but are simpler and use off the shelf components. “I would love to have had the opportunity to build this rover in high school, and I hope that through this project we provide that opportunity to others,” said JPL’s Tom Soderstrom in a post announcing the OSR . “We wanted to give back to the community and lower the barrier of entry by giving hands on experience to the next generation of scientists, engineers, and programmers.” The OSR uses Curiosity-like “Rocker-Bogie” suspension, corner steering and pivoting differential, allowing movement over rough terrain, and the brain is a Raspberry Pi. You can find all the parts in the usual supply catalogs and hardware stores, but you’ll also need a set of basic tools: a bandsaw to cut metal, a drill press is probably a good idea, a soldering iron, snips and wrenches, and so on.
