It wasn't very blatant, it's not like it was 2" off the ground-but you could see it come up.

If that's the case I apologize. I remembered a lot of jostling, and I remember the bumps being the cause of the ball-carrying, and I guess I inferred subconsciously that 33 got pushed up the ramp :rolleyes:

and when I said I was disappointed in some referees, I was referring to earlier competitions. There was an instance where our hook missed (during the finale), and ended up hanging 5 or so inches outside of our bumpers, and the refs called a penalty. Afterwards, we pointed out that robot is allowed to expand to the finale configuration (eg. go outside bumpers) during the finale, the head referee said that you could only get wider in the space above the robot O.o we then showed him the rule, and he waived the penalty. I would understand if it were in the earlier competitions, but I believe this was during the Michigan State Competition.

@ Wayne: If it was obvious, I would assume not. That said, I wouldn't put someone who's easily pushed around in that precarious position ;)
And if you're attempting to find a way to defeat 469, I would suggest looking into what 294 did... they were amazing. Somewhere in the thread below, the driver coach (I think) for 294 described their strategy.

Absolutely right. Everyone has the right to push the envelope, that is what sometimes separates the good robots from the great. Any penalty-capable feature is a calculated risk. You can be sure there were many momentary lifts by pinch rollers this year that were not caught by referees. Judging how far you can push a rule is a design decision we face with almost every game. Just one aspect of predicting what the gameplay will really be like.

I don't advocate pushing the rules in hopes of slipping something past the referees. I just wouldn't write off a good idea because it introduced he possibility of a penalty. Many pinching roller ball collectors didn't compensate for irregularities in the floor and "carried" balls for brief periods. I think they deserved to get called for carrying whenever they did it, and the referees didn't owe them the benefit of the doubt on a close call. Nevertheless, a functional ball collector that collects an occasional penalty is better than no ball collector at all. 469 may have gotten called for active mechanism above the bumper once or twice, but that doesn't mean their ball deflector switch was a liability. 1918's wide ball collector was physically capable possessing more than one ball at a time, but the ease of ball acquisition outweighed the risk of penalties and the occasional hassle of having to take evasive action.

Is that part of normal contact or is that forcing a penalty? (For example, if my alliance is playing against 469 at the MARC and we put a robot on the bump right next to them, would we get a red card if somebody pushed that bot off the bump?)

My gut feel is that getting pushed in would be be considered forcing a penalty and not called. However, if the team that got pushed in did not try to immediately get out, it would then be a penalty. Getting pushed in isn't an excuse for having 2 robots playing defense in the opponents home zone.

Yes this is exactly what I meant by a calculated risk/reward. We also had and extra-wide ball magnet that could easily possess more than one ball, but its extreme effectiveness in easy acquisition made it more than worth the risk. I don't believe we ever recieved a multiple possession call, although I can't claim for sure that it never inadvertently happened.
