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?

All of them are valid as long as the Trackball has circled around the opponents' Finish Line beforehand, the Trackball crosses in the forward (counter-clockwise around the Track) direction, and the Trackball doesn't hit Redabot 1 before it hits the ground or another bot after it crosses the Finish Line.
In other words,

<G08> All TRACKBALL scores are awarded to the ALLIANCE associated with the scored
TRACKBALL, independent of the ROBOT that may have caused the scoring action to occur.

dlavery - I think the way that he sees it, placing it up there first and then knocking it off is equivalent to knocking it off - earning no points by the scoring table in the manual.
This is true, but you do get points, anyway, since it counts as a Hurdle.

P.S. - in a short answer - Yes Hurdle, Yes Hurdle, Yes Hurdle, Yes Hurdle

Unless I remember the rule wrong, they're all hurdles. I don't have a copy of the manual in front of me, but if I remember correctly, to count as a hurdle, the ball as the cross the finish line over the overpass, and hit the ground or another robot before touching your robot again.

In scenario one, this is obviously fulfilled (I'm assuming that the ball touches the ground before you touch it again).

In scenario two, I would be confused as to who does the ball not have to touch - red 1 or red 2 - but if it touches neither, or whichever it can, it sounds like a hurdle to me.

In scenario three, I again see no problem with red 1 doing the extra lap before knocking the ball off.

In scenario four, I again see no conflict with the rules.

Summary: To me, they all sounds like valid hurdles, with the interesting question stemming from scenario two - who must avoid the ball?

Question:
If you hurdle, does it have to pass your opponent's finish line before it counts as a hurdle again? Or can you nudge the ball backwards so you teammate can hurdle the same ball right after you without the ball making another lap?

If this is possible, two robots working together could hurdle much quicker.

Our question is once you set the tracball on the overpass and knock it over is your bot allowed to go in reverse on the course in order to allow it to clear the overpass?

I've got a slightly different twist on the before mentioned scenario:


If redabot, in an attempt to hurdle, places the red trackball on the overpass and blueabot, in an attempt to stop the hurdle knocks the red trackball forward off the overpass and the red trackball strikes blueabot before the red trackball hits the ground ... is it a hurdle?

Since Blueabot was the last to touch the Red Trackball before it completely passed through the plane of the finish line, Blueabot becomes the hurdler. If, as in this twist, Blueabot (or another blue alliance robot) touches the trackball before it touches a red alliance robot or the floor, it is not a hurdle.
