In this case, a robot might just be hamstrung for the match, unable to pick up another tube.

And that's when you launch plan B: the power to push an opposing robot sideways across the length of the field. Too bad the kit doesn't come with skyway wheels anymore....

I think that you might get a yellow flag if you drop it on an opponent on purpose...other than that, IDK?!

Re: <G09> Dropping Tubes on Your Opponent

i'd pick a yellow card team that did that,

does anyone know if you have a yellow card at the end of the Q's does it go away for the Eliminations,

hopefullly, this is the case

Re: G09 Questions

I don't think it will matter. I don't see the refs going "Oh, a robot dropped a tube on your robot, you have 2 tubes, YOUR GOING DOWN!". I wouldn't worry about it. The other guys tube is quite useless to you, you can't score with it or anything.

This rule deserves clarification at minimum.

Re: <G09> Dropping Tubes on Your Opponent

I think that it is a perfectly legal and legit strategy, but I can see FIRST redeclaring it as illegal similar to the situation in 2005 with the loading zone penalties and teams intentionally backing up into passing teams to inflict high penalties points.

Edit: I know that this is against FIRST spirit

I would consider a robot like this can be violating the rule of robots that can't be built for the destruction of other robots.

I would think and hope the refs would understand if a ring accedently falls on your robot and you can't remove it.

Can you do this? Does your flag have to be at the top only at the start of the match, at which point you could actuate it to "safety", or actuate something over it to "protect" it?

Obviously if you extend beyond it, it will no longer be at the top, and I haven't seen anything saying the flag needs to be above the highest point on the robot yet...

As long as it was movable and not locked in place for most of the match, you'd be protected.

Re: <G09> Dropping Tubes on Your Opponent

Every team will have a 3' high flag on their bot. This is a potential object that the rings can drop onto your bot and not be easily removed. FIRST will probably come out with an update soon (I hope)
BTW, how many rings do you think will fit onto the flag? :)

But, this is for FIRST to clarify.

Re: G09 Questions

FIRST defined possession of a tube to be contact with it at more than one point, so you don't NEED to control the tube to possess it.

can you referance this? i've read though the rules and didn't spot anything relating multiple points of contact to possession; i agree with don rotolo: control is the key to possesion.

Re: G09 Questions

woops. I was reading the on the floor part of possession.
However it does say if the robot is supporting the ring it is possession

Quote:

POSSESSION: a GAME PIECE is considered to be in the POSSESSION of a ROBOT if it is
being fully supported by the ROBOT, or if the ROBOT is controlling the position and movement of the GAME PIECE. A GAME PIECE on the floor is considered to be in the POSSESSION of a
ROBOT if it contacts the ROBOT at more than a single point (e.g. the ROBOT has a concave
"plow" feature that is used to push the GAME PIECE in a controlled manner)
