How does descoring work?

[jgannon]

I must not be understanding this correctly... can someone help shed some light?

<G36> HOME STRETCH Height Restriction – ROBOTS in the HOME STRETCH of the opposing ALLIANCE can not be more than 6 feet tall. A PENALTY will be assigned for each infraction.

<G22> Direction Of Traffic – ROBOTS must proceed around the TRACK in a counter-clockwise direction. Once a ROBOT has CROSSED a LANE MARKER or FINISH LINE, it shall not break the plane of the line by moving in the clockwise direction. A PENALTY will be assigned for each infraction.

How do you ever get your ball down from the overpass overlooking your opponent's finish line? You can't even reach the overpass when you're in the opponent's home stretch, and because the edge of the overpass is aligned with the finish line, you aren't allowed to reach to the overpass once you're out of the home stretch. Do you just have to hope that your opponents don't wait until the end to knock your ball down? In the end game, can you not score on your opponent's side? Can you not descore on your opponent's side?

Seems you drive past the home stretch, turn around, and either grab it or knock it off from there. Sucks...

edit: thinking. I'll prob come back to this thread.

Based on <G22>, I'm pretty sure that that's not a legal alternative.

You could knock the ball down with a blast of air. If your robot is six feet tall, it's only six inches to the overpass.

[Scott358]

The ball weighs about 10 lbs, so a blast of air from six inches away is going to be tough.

I assume the ball is nested in the bridge, therefore the bottom might be below the 6' limit. This might allow you to punch the ball off. Thoughts?

Getting my math out, brb.

But to jgannon, you can turn around and knock it down.
7.2 Definition of crossing

You're considered crossing when ALL PARTS have crossed the line. GO past, turn around, don't fully cross the line, you're fine and dandy.

No! What you describe would not be considered crossing, but it would certainly be breaking the plane. Remember, "Once a ROBOT has CROSSED a LANE MARKER or FINISH LINE, it shall not break the plane of the line by moving in the clockwise direction." Any motion that caused you to break the plane of that line from there would have to be clockwise in nature.

The key word here is "moving." Wouldn't pivoting be allowed? You could at lest pivot counter-clockwise if that is where the problem lies.

Hope you're not getting too worked up, just thinking in a lot of directions and not spent a lot of time arond the rules. You're definitely right there. We might be limited to the bottom of the ball, going to figure out how low it hangs in a second.

Another thought though -- what if they intended for it to be a penalized process? If you want to get your second ball into play, you have to gamble the points?

If so, the human demonstration didn't show it.

Use another ball to descore a ball?

Edit: As seen in the Arena rules, the Home stretches are only a quarter of the field each. Go past your opponents finish line and you're free to return to >6' height. You can stop and drive around in a given quarter of the field, as long as you don't go back across a line.

[Ty Tremblay]

You cannot be over 6' high in your opponent's home stretch, so you must go under the overpass in order to reach high enough to descore the ball. BUT, when you go under the overpass, you cannot touch the ball because you would then break the plane of the opponent's finishline, causing you to recieve a penalty.

This seems like a vicious circle to me.

[Ragnarokae]

Here is a link to another thread with a math proof regarding the height of the ball on the overpass. http://www.chiefdelphi.com/forums/sh...t=60666&page=4

We have approx. 2 in or less to work with...

Sorry everyone, I forgot to hit refresh, and thus missed LordTalps' post.

You can go in any direction in a given quadrant, you just can't cross the lines going the wrong direction. Otherwise if a ball rolled into a corner, you're in extremely hot water.

edit: And you can be on the finish line in the wrong direction, just not CROSS it, from how <G22> reads to me.
