The robot flips tires so their white centers face up and moves them into their large target circle.

  • If the light (blue tread) tire is white center up: 10
  • If the heavy (black tread) tire is white center up: 15
  • If white-center-up tires are completely in the large target circle: 5 each
  • For all scores, the tire needs to be resting on only the mat.


If the heavy tire crosses the red flip line at any time, even partly, it scores zero.

The flip line runs all the way north to south. Only part of it is shown.

FLLCasts Tip

The tires could be flipped with a an attachment that follows the idea of FLL 2017: Attachment The Manhole Cover (08th) Mission, but stronger because the tire are way heavier.

In this mission the black tire cannot cross the red line, which means that you cannot bring it back to base and flip it. If the the black tire crosses even partially the black line - the points don't count.

This is not true for the blue tire - meaning that you can bring it in base, flip it and then push it back into position.
