Re: "Heading" balls?

So then could you put an active mechanism in the bumper zone(10 to 16 in.) without violating G45? The mechanism wouldn't be above the bumper zone, so technically. . .

Re: "Heading" balls?

"When reading these rules, please use technical common sense (engineering thinking) rather than “lawyering” the interpretation and splitting hairs over the precise wording in an attempt to find loopholes."

Re: "Heading" balls?

An actuated mechanism used to "head" the balls would very likely be a violation of G45.

However, I haven't spotted anything yet that would restrict heading with an inactive mechanism. It seems like a plausable way to deflect deposited balls back to your half of the field.

Your bumpers are in the bumper zone and cannot be articulated.

Re: "Heading" balls?

Also, what would the definition of carrying be? The rules aren't very clear. They state:
Quote:
CARRYING: POSSESSING a BALL that is not in contact with the FIELD

POSSESSION: Controlling the position and movement of a BALL. A BALL shall be considered in POSSESSION if, as the ROBOT moves or changes orientation (e.g. backs up or spins in place), the BALL remains in approximately the same position relative to the ROBOT.
So, how long would the ball have to be on the robot before it would be carrying?
Theoretically, if a ball falls on you while you are moving, and it stays on top of you, that would be carrying.

In response, the bumpers would close to the bottom of the zone so that the active mechanism could be closer to the top.

Yes, that would be carrying. It makes it very important to have a sloped top to your robot so that balls cannot stay up there.

Re: "Heading" balls?

But how long could the ball stay on the robot while stationary before it becomes carrying?

I'd guess it's up to the judges. Your best bet is to move your robot so that it is no longer carrying the ball, just in case (ex. if the ball drops on to your robot and is on a ledge, move your robot so the ball moves off) .

The moment you're in possession of it.

Re: "Heading" balls?

But you are allowed to be in possession of a ball just as long as the ball is moving relative to where your robot is

Yes, but if you're in possession of a ball while it's not touching the ground, it's carrying.

like i said you are not in possession of the ball becuase even if the ball is not touching the ground the ball can be moving while you are stationary so it is in a different position relative to the robots position(i.e. the ball does not remain in approximately the same position relative to the ROBOT)
