3. 0 2 1 4 3 5 8 76 9 Objective The Great Moonbuggy Race requires students to design a vehicle that addresses a series of engineering problems that are similar to problems faced by the original moonbuggy team. The main objectives of the competition are to design, build, and race a human-powered vehicle able to conquer typical obstacles that a moon rover might encounter.
