Ball Return

Can a robot block balls in the ball return so they can't make it to the field? Even knock them out of the channel to get control of them sooner.

If I'm interpreting this correctly <G47> will answer your question

<G47> BALL RETURN Interference - ROBOTS may not interfere with BALLS in contact with the BALL RETURN. Violation: Two PENALTIES per affected BALL.

I hope you read the manual.

this brings up a question,

could you then stop your robot in front of the ball return and nock them back into your alliances zone right as they come off the track?...

you can only hang your robot in the last 20 sec. right?

Re: Ball Return

Any mechanism used to interact with the ball must be below the bumper zone or you will get a penalty every time you use it. However, if you for example, angled the top of your robot to affect how a ball would bounce off of the top of it, I don't think there's anything wrong with that.

Also, if you somehow manage to touch the tower without expanding beyond your normal configuration, you can hang any time you want without penalty, since being in contact with the tower allows you to expand to final configuration.

Yes, as long as they are off the ball return before they touch your robot.

I find nothing that states this.

It appears that you can hang from the tower and expand to the FINALE CONFIGURATION at any time during the match (unless there's another rule that I've forgotten). However, you are not protected by <G32> or <G34> from opponent contact.

That sounds like it could be a decent strategy, as long as you never gain POSSESION of the ball while it is in the air. (i.e. no chutes)

My bad, I just reread the configuration rules and got a few words changed around:o

Possession if defined as controlling the ball while you are in motion. If you are just hanging (or sitting) still, a chute, with no active mechanisms above the bumper zone, seems legal to me.

That is what I would think. Possession is defined as the ball remaining in relative proximity to the robot as the robot moves. If you are sitting in front of the chute, then the ball rolling off the robot is changing proximity and not being moved be the robot. You could look at this as the equivlant of a soccer player stoping a ball with their upper body.

You can hang whenever you want from your own tower, but your robot is not protected until the last 20 seconds.

Provided any expansion you do is while you are in contact with the tower.
