robot dimensions

[Dale]

Page 4 of the Section 8 "the Robot" defines:

BUMPER ZONE – the volume contained between two virtual horizontal planes, one inch above the floor and seven inches above the floor.

And then R08 "P" states:

P. BUMPERS must be mounted to the ROBOT within the BUMPER ZONE, and must remain there. The BUMPERS must not be articulated or designed to move outside of the BUMPER ZONE.

OK we and a few other teams got <R11> infractions at Finger Lakes. I only wish that inspectors had checked our mechanism operation during the power up check. Now I notice it is only in the cursory visual inspection list on the inspection sheet. Given this unique constraint this year, I believe it warrants checking with power on.

Sorry for your penalty, however, if you read the bottom of the inspection checklist( http://www.usfirst.org/uploadedFiles...%20Rev%20D.pdf) the team captain and mentor certify that the robot is built to the rules.

We, the Team Mentor and Team Captain, attest by our signing below, that our team’s robot was built after the 2009 Kickoff on January 3, 2009 and in accordance with all of the 2009 FRC rules, including all Fabrication Schedule rules. We have conducted our own inspection and determined that our robot satisfies all of the 2009 FRC rules for robot design.

Wait, infractions as in plural? You mean you got multiple penalties for it? Why didn't you fix it after the first one? Some of the rules seem obscure and easy to overlook, but that one seems to be one of the main rules of this years game. I just don't see how multiple teams at a regional overlooked it. Sorry, I know overlooking a rule is annoying. I've had related problems my rookie year(completely missed the motor restrictions). But, this is always just a reminder to read the manual more carefully next year.

Robert,
What exactly does your robot change from starting config that caused the violation?

We have pneumatic tube fingers on our ball harvester. Over the course of the build season they became longer; not to pick-up but to aid moving the balls through the storage area on an upper roller. The infraction was called on Friday at our 4th match. We had 6 matches in between to try to fix this. We trimmed them to what one inspector said was OK but actually not enough so we were DQ'ed again. The final fix required we move the frame/bumper out 1/2 inch (we were slightly undersize) and to put the roller on a 3/4 spacer towards the chassis. Admittedly, something we should have done before but didn't get around to.

OK, Robert.
I am wondering what the difference was between the inspector and whomever called you on the infraction? Was the lead inspector involved? From what you describe, this is the same action I had to advise a team at Midwest to perform in order that their pickup "brush" would remain inside the bumper perimeter. Hope it is fixed now. Do you have another event you are attending?
