Re: New size/bumper rules that every team should know
This rule also makes it so the square KOP chassis can not be legal if it is made to the dimensions in the instructions

Re: New size/bumper rules that every team should know
The rules do not say how much of the bumper has to touch the frame vertically, only how much horizontal gaps you can have. (I believe, I'm not a rules expert, but read through the rules twice. Think that was the same as last year.)

Re: New size/bumper rules that every team should know
I'm still a little unclear on the frame permiter. If you choose the 30x32x36 size, does that mean you need to account for the ~3.5" of bumper on each side, leaving you with a max frame size of 23x25?? That seems a bit ridiculous. Granted it's probably doable, but I can't imagine FIRST having that tight size constraints

I think the fact that the square configuration of the KOP chassis is illegal needs to be emphasized. I imagine some teams will assume that all of the configurations would be legal becasuse it comes with the kit.

Quote from engunneer:
the KOP frame has always been bigger than legal, so the team can decide which way is front and so the team can decide where to cut. I'm far more worried (as an inspector) about teams not realizing the bumpers must be inside the size box. But people must also be careful that the bumpers are not at the edges of the volume if they need any manipulators to extend beyond them because you cannot exceed the total volume at any point in the game R03. Maximum ROBOT size, including BUMPERS and all extensions, must be constrained to one of two volumes: A. 36in.by40in.by24in.tall(~91cmby101cmby60cmtall). B. 30in.by32in.by36in.tall(~76cmby81cmby91cmtall). The ROBOT must remain constrained to the maximum inspected volume at all times during the MATCH (i.e. A ROBOT may not switch between volume A and volume B without being re- inspected). Sorry I'm not better at quoting things properly, but this is a big change that bears discussion. |

Re: New size/bumper rules that every team should know
A frame perimeter of 23" x 25" seems tiny! Any ideas of how to make the most of vertical space?

Re: New size/bumper rules that every team should know
When I first read the rule with the green background, it made no mention of bumpers.
However upon further searching I found this: R03 Maximum ROBOT size, including BUMPERS and all extensions, must be constrained to one of two volumes: ... I'm with Blake on this issue and think it needs to be explained by FIRST as its hard to believe they really want us to build small robots with a frame perimeter of 120 inches. Dave |

Re: New size/bumper rules that every team should know
The wcp DS west coast gearbox is about 12" end of axle to end of motor. Two of those sitting exactly next to each other already puts you outside the the frame permiter and into your bumpers if you go with the tall configuration if you put the gearboxes on the long side. Idk, I think that rule is a little ridiculous. But if that's how it's intended to be, then everyone has the same rule and we can't say it's unfair, so we will work around it.

Re: New size/bumper rules that every team should know
Kind of makes sense that they released these for 2017, huh?
