YMTC: Bluabot comes to rest touching a blue trackball on the overpass

[JesseK]

This is easy if you've read the latest Q & A:
At the end of the match, when the timer reaches 0, the trackball was not in free-flight. The robot's exact position when the clock reaches 0 is all that matters. Therefore, when the clock hit 0 the robot was not in contact with the ball and therefore meets the requirements of a valid end-game bonus.

If the Trackball is not in free-flight (i.e. in contact with a Robot or the Overpass or other field element) when the clock reaches zero, then the Trackball’s contribution to the score will be based on the conditions that exist as the Match ends.
