Hurdling using the overpass
 
I realize that this question has been asked (sort of) on other threads and answered (again, sort of). However, given our specific strategy, I am curious as to if this technique would count.

So, our theory is that we get the ball to around 6 feet, the push it from below such that the TRACKBALL rolls up onto the OVERPASS. (we've tested it and it works). Now, if the ball rolls all the way across and falls off then we just let it bounce and continue on. However, if it settles into one of the depressions (far more likely) we just push it out (with the same device that pushed it on) and onto the next quad (completing the CROSSING) and then proceed to let it bounce and then we gain control again and so forth.

If either scenario (especially the second) happens, is it a hurdle? I would say yes, simply because it crosses the finsih line while being above the overpass (remember, crossing isn't complete until the whole thing goes over the line). What do you think?

Re: Hurdling using the overpass
 
The only real restrictions on Hurdling are that the Trackball has to go over the Overpass and that it has to touch the ground or another bot afterwards, so your tactics look legit to me.

I believe that your analogy is correct.

Sorry, but by analogy being correct, do you think that it would count as a hurdle?

Re: Hurdling using the overpass
 
Yes, our team is also looking at this being a legal hurdle... If I hear different I will post a new reply.

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.

HURDLING: The act of completing a HURDLE. To be considered in the process of HURDLING, the ROBOT must:
be in its own HOME STRETCH, and
be in POSSESSION of a TRACKBALL, and
be moving toward the OVERPASS and/or elevating the TRACKBALL so that the top of the TRACKBALL is higher than the LANE DIVIDER.

All of these points seem valid with what you want to do. I don't see any problem with pushing it over. The only thing I can see that may pose as an issue is speed. But, its perfectly legal it looks like.

THere is no mention of speed in the rule, so it sure sounds like a hurdle to me!

I wasn't saying too fast or too slow. However, in general it would be slower than just placing it over the overpass.

How legal is this:

Get the ball over the overpass, without passing the finishline yourself, and then have an alliance member push the ball back to you. Then repeat.

There isn't any rule about the ball going backwards around the track (that I know of):D .

(Edit) Sorry, forgot about rule <G13>, that ball has to pass the other alliances finish line.

MrForbes 09-01-2008 08:28

Re: Hurdling using the overpass
 
You can do that, but it will only be scored as a hurdle if it passes over the opposing alliances finish line every time....

see rule <G13>

Re: Hurdling using the overpass
 
Should be fine as long as the hurdling robot is not impeading and the alliance robot is able to make the trackball cross over the opposing alliances finish line before it returns it to the hurdler.

Note: the alliance robot could pass the trackball directly back to the hurdling robot so that the hurling robot could place the trackball on the overpass for the 12pt bonus at the end without having the trackball cross the opposing alliances finish line

You're right Squirrel, Sorry.

Re: Hurdling using the overpass
 
id say that it would b a complete hurdle because it did go completly over the over pass

Re: Hurdling using the overpass
 
The problem might be in the second point of the definition of HURDLING. While the ball is sitting on the overpass, the team has given up POSSESSION.

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.
