rule question on scoring above overpass

[Robo_Coyote]

my idea is that it would be fast when trying to score, to place the ball on the overpass, then drive under and retrieve it from the top of the overpass. I think this will be easier than trying to track the bouncing ball back down. Does anyone see anything questionable about this rule wise?

From the manual (which is quality reading, lemme tell you), emphasis mine:

HURDLE: When a TRACKBALL CROSSES a FINISH LINE while passing above the OVERPASS
and then contacts either the floor or another ROBOT before re-contacting the originating ROBOT.

Thanks Billfred. I had heard a rule about touching the Trackball existed, and was reading up on it, but couldn't find it.

Thanks for that manual quote.

But, while the trackball is sitting on the overpass it hasn't yet CROSSED. So is the second-touch rule in effect yet?

You also run into rule G22. If you reach back to grab the ball, you'll be crossing the line in the clockwise direction.

this is very tricky.
because your trackball is now resting on the overpass, part of the ball extends past the finish line. if you now dislodge the ball, using your robot then you get no points, since you are touching the ball while it is crossing the line.
you get no 2-point score nor the 6-point bonus. however, if you pull the ball back from the overpass, and then hurdle the ball correctly, the score should be given.

And that's another question. Does the rule prohibiting touching the ball as it crosses the line apply to hurdling?

I believe you are allowed to be touching the ball during hurdling. I also believe that will a clarifying update from FIRST explaining this. Lots of threads on this site asking the same question.

I do not believe that you will score if you are touching the ball while hurdling. The reason is that 2 points are scored because the ball passes the line with a 6 point bonus for being over the bar. Since the ball was being touched while crossing the line, there would be no point for crossing the line and and as such no bonus points either.

Yea Dan,

I saw your post and reasoning on other threads. I guess only time will tell who is right

I believe your logic is correct for going under BUT not for going over.

If I knew that I would see you in Atlanta I'd put a friendly wager on it

um you can definitely work around that just make you manipulator work above your robot

i.e. put the ball on the over pass

and move foward ( cross the line for two points yessssss!!!!!!!! more points) and reach back w/o moving your entire robot back

[Andrew Bates]

So at what point do you actually have to release the ball?

[Tom Line]

I suspect you are doing gyrations that are not necessary. As someone else said, we need clarification from First.

1. Can you touch the ball while hurdling it through the start/finish plane
2. Can you break the plane from the non-home stretch side of the field with your gripper to knock the ball off in hybrid

hehe.

If we make it to Atlanta (we'd need to win the BAE GSR) I'll take that friendly wager ... say a box of Krispy Kremes? (**Hey Dave, I'd split 'em with you **)

We have a simmilar dilemma:
What actually is considered a hurdle?

^ is that really a possibility? Is putting the trackball on the overpass and just pushing it off again considered a hurdle? Can the ball even touch the overpass when its hurdled?
And then ofcourse can you touch the ball during the hurdling?
