NASA Mars Rover Building Kit

Course Description:

This course contains 5 lessons.
NASA has made possible for everyone to build a scaled down versions of the Rover robot which was sent on Mars! 
Following the steps of this course, you will build the robot yourself. It is designed for about 6 months ( 200 hours).
In the words of NASA lab itself: 
The JPL Open Source Rover is an open source, build it yourself, scaled down version of the 6 wheel rover design that JPL uses to explore the surface of Mars. The Open Source Rover is designed almost entirely out of consumer off the shelf (COTS) parts. This project is intended to be a teaching and learning experience for those who want to get involved in mechanical engineering, software, electronics, or robotics.
