Detailed Instructions


Level 1: the physical Mini Racer Competition. Design, test, 3D print and assemble the fastest car. This car will be raced in heats of six on a Hot Wheels track that is 20 feet long. The start will be four feet at a 45 degree angle. The remaining 16 feet will be flat.

Level 2: In addition to this submit your complete car assembly digitally as a zipped compressed file. One week prior to the competition. These cars will be loaded into the Solidworks Track Assembly to digitally compete with the competition.

Level 3: In addition to Level 1 and Level 2 submit the Solidworks generated charts for acceleration, top speed and total time to complete the provided track.

Level 4: In addition to Levels 1, 2 & 3 submit your hand calculated acceleration, top speed and completion time for the provided track. Compare the results of the hand calculations and the digital (Solidworks) results. Discuss if there is a difference and the possible reasons for the differences.
