BUMPERS ARE INCLUDED IN ROBOT VOLUME THIS YEAR!
Does anyone know if the bumpers are included in the volume size, or if they can be excluded and the frame size of the robot is the considered volume?

Re: BUMPERS ARE INCLUDED IN ROBOT VOLUME THIS YEAR!
I am bummed about the number of robots that will come to competition this year unable to compete at all. Some years, overweight robots need to get Swiss cheesed, or lose a mechanism. Some years, bumpers need to be reconstructed. How does a team recover when they need to lose ~6" on both X and Y? And then rebuild the bumpers?

What's the rules about bringing something like that in? Is it like part of the allocated weight for parts or no? |

Huh... alright. We'll maybe bring one or two assembled kitbots to SF and SVR if it has the potential to help out some rookies. |

So who's asking this Q&A? I don't have a login to pester the GDC anymore, so I can't. |

We've had size changes before - didn't the total size go down when they switched to measuring the perimeter? And there was a year where your height changed per your weight. (Although I admit that's easier to fix than the horizontal sizes.) And teams have shown up oversize before, with or without a size change. Or have had totally out of compliance moving frame parts. Even a team that showed up with their original kit of parts, nothing built. And they get to compete after a lot of good assistance from other teams in the pits. |

Re: BUMPERS ARE INCLUDED IN ROBOT VOLUME THIS YEAR!
This happened to my team our rookie year. We were 1/8 of an inch too wide in X and Y (As the lone mentor, I thought it best to make as big a bot as we could!) When we didn't fit in that blasted box we had to tear down and cut an inch in both dimensions (C-channel kit bot - 2012). It was a cascading nightmare. By the time we got the thing back together and inspected, it was Saturday morning. We "participated" in exactly 3 matches that year.
FRC almost lost me right there. We need to do what we can to warn rookies of these constraints. |

It was easier to make these changes with the old C-channel chassis, as that used chain to power all the wheels. Chain is easy to modify and make shorter. With the current robot chassis and most teams using belts with it... that's going to be more difficult. But hey, there's nothing in the rules that says your drive train has to be functional for you to pass inspection and get points for "participating" in a match. Hopefully inspection teams at all events can be focused and creative in getting teams legal to compete, and then once legal getting them functional again so they don't miss out on any possible points in matches. |

Assemble kitbots would be considered part of your withholding allowance...if not in a bag. I believe that you can freely exchange withholding materials and COTS but not what is in your bag...After reading QA 360 I am wrong on this... evidently you may use what is in your bag for another team..... just remember you are limited to 2 bags. You GP is showing... but be careful... You can always bring in an unassembled kitbot...as COTS... without BAGGING and it will not count against the withholding allowance |

My kids are editing their video right now. We hadn't met since Saturday so this is our first real chance to work on it. It looks like fun! Hopefully they make it in by the deadline.

Re: BUMPERS ARE INCLUDED IN ROBOT VOLUME THIS YEAR!
Everyone,
If a team comes in over size please do not take it upon yourself to make any changes. Please involve the LRI who will help the team make decisions and then move on. They are in direct contact with the Head Ref, FTA and others at HQ who can best handle situations involving teams. All LRIs have my cell phone number and I have several other people I can turn to. Thanks. |
Re: BUMPERS ARE INCLUDED IN ROBOT VOLUME THIS YEAR!
Then, does anyone know why this rule was implemented for this year?

PERSONALLY, I see it as a throwback to the days of the sizing box: If your robot fit, you were good. Otherwise, the inspectors would show you which bolt you needed to cut off. Many teams learned--the hard way--that the box was absolute, and designed about 1/2" or 1" undersized. It was actually relatively easy to measure, if it was set up (properly). The sizing box went away in 2013, as I recall. |
Re: BUMPERS ARE INCLUDED IN ROBOT VOLUME THIS YEAR!
I don't have any insight to how the GDC reached this decision... but if I had to guess, I would go a different route from Eric. Part of the challenge this year is holding a lot of balls inside of the robot. So, the maximum volume is pretty important!
In the past, FIRST has gone with maximum frame dimensions (either in terms of X*Y or max FRAME PERIMETER) combined with a maximum distance you can extend past the frame. They could have done that this year. However that would have drastically limited team's creative ability. If they just sized the robots 7" less in each dimension and said you could expand 3.5" past the frame perimeter, you would miss out on things like over the bumper pickup mechanisms. So, I think these sizing rules are the most flexible rules the GDC could do while still limiting the overall storage capacity for teams. |

I hate making bumpers, and since my entire team does too, me and my brother are heads of the bumber team. We have one other student at least.
