3. Criteria & Constraints Big Challenge: Design a vehicle that will go fast, far, straight, and carry a load. Big Challenge: Design a vehicle that will go fast, far, straight, and carry a load. Criteria (measurable & quantifiable) Go Fast Go Far Go Straight Carry a Load Travel over different terrain Must travel at least 5 meters Have a Michael Phelps mindset Rules 1.The boss is always right 2.If the boss is wrong…see rule #1 Constraints All materials used must come from home Must be built with parts that are not originally designed for vehicles or moving objects Maximum dimensions of your vehicle: Length: 25 cm Width: 10 cm No electronics Gravity is the only external force that can act on the vehicle after it is released. Any additional forces must come from the design and internal workings of the vehicle itself. The vehicle cannot leave the ground when in motion Vehicle design must be practical and realistic for completion 1 month from now
