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.
