explanation video guidelines

The explanation video is an opportunity for teams to highlight elements of their solutions and to show  judges the details of how scoring items work or are constructed.

Be sure your video is clear and audible so the judges can see all your wonderful ideas come to life! Remember, the video may be edited. Zoom in to show how you designed and built each item and demonstrate how it works or what materials it was made from. Non team members may appear in the explanation video but the team members are to provide the explanation.

The explanation video should emphasize, but is not limited to details for the following items in each problem:

For the vehicles

  1. Demonstrate that each vehicle to be used for scoring attempts meets the size limitations
  2. Demonstrate that the speed bump meets the size limitations (if that task is to be attempted).
  3. Using the vehicle to demonstrate. Provide a brief explanation of how each vehicle and propulsion system to be used operates.
  4. Provide a brief explanation of how each vehicle solves the required tasks (functional engineering).

For the site

Show that the Start and Release lines are 6’ long and are 6’ apart.
