Defensive Strategy - cornering opponents ball

If a robot from the other alliance is trying to push my trackball into a 135^o corner, I'd tell my drivers to just start pushing their robot. No high speed ramming or egregious behavior, just solid bumper-to-bumper contact. With the covers on the trackballs being so slippery, something will give, and I doubt that trackball will stay cornered for very long.
Now if there were 90^o corners on the playing field, this strategy would be much more viable. But with the current field, I can't see it working for very long against a robot with a decent driver and drive train.

Someone forgot to take into account the force if ramming a ball in a corner, and it getting popped.



I'm glad I found this thread.

Here's an example of something that has happened.


Team A traps team B's trackball against the corner consisting of the grated area making the Robocoach's wall & the Lexan players station wall on Team A's lane side.
Team B can not get to their trackball without crossing the Lane Divider in the legal direction, & going around Team A in reverse (illegal way) over the Lane Divider line.
To do this, Team B would get at least one 10pt. penalty.

There is a clear way to go past, so Team A is not technically blocking a lane / impeding traffic. (No Penalty)

Team A pins Team B's ball there for a good 30 seconds while Team B makes an effort to get it by staying around Team A and bumping Team A so they will move away from the ball.

That's not the end of the story though.

Upon Team A finally letting up on the pinning strategy, & pushing it forward over the Lane Divider line, Team B grabs the ball... It's now losing air from being pinned so tightly into the wall.

Team B tries to grab the ball but fails at hurdling the ball as it falls out of their grabber before it is at a height to go over the Overpass & is made inactive on the field.
Now, with a minute or so left in the match, a new ball is made ready at the sidelines, but never put into the arena, and the popped ball sits there just losing more & more air with a new ball nowhere to be found.

Team B loses the match.

Team A is assessed no penalties for any play in question.
(Popped ball, impeding traffic, pinning an opponent's trackball)

Upon waiting for a decision, & seeing the score with Team B losing by a small amount (which a good ball would have been able to compensate for), the match & plays are legally disputed with a Student from Team B & the Head Referee, but no penalties are given to Team A, nor is a rematch granted.


What do you think about pinning a ball now, and the legality of it?

Actually, let's do one of these. Based on the 2008 rules, You make the call!!
