Variations on this scenario (all assume counterclockwise direction):

1. Redabot 1 puts the ball on the overpass, and then immediately knocks it off.
2. Redabot 1 puts the ball on the overpass, and then Redabot 2 knocks it off.
3. Redabot 1 puts the ball on the overpass, circles the track, and then knocks it off the next lap
4. Redabot puts the ball on the overpass, and then Blueabot knocks it off.

Which of these counts as a hurdle?

Hard to tell. Hurdling is defined for a robot, but the definition of Hurdle--which is separate--is a little unclear. At this point, Scenario 3 wouldn't count (I think) because it would be a place and a knockdown. Scenario 1 might count, if the ball never settled. I'm not sure about the other 2 scenarios.
