Re: Wide C-Base Frame Corners

Unfortunately, Tristan is correct on the letter of the rules - having an open 1"x1" gap on the corners of the robot does not permit legal bumpers or bumper support. It something I noticed on our robot in week two or three, and we cut up an old frame to remake two of the rails extend into those corners. We did it to ensure there would be no issues with inspection at any events.

That said, there is the letter of the rules, and the intent. Teams have been making their frame with that 1"x1" gap in the corner for years, and it hasn't had any noticeable impact on bumpers. While there are undoubtedly some inspectors out there who will stick to the letter of the rule (and the LRI's are forced to stick to the letter of the rule as its been handed down by the GDC), many more will not even notice that issue on the corner, as they're so used to seeing it built that way for every robot every year.

As far as bumper problems go this year, though, this is one of the easiest ones to fix. All you need is to stick something in the corner - even bolting a thin piece of sheet metal over that corner will technically define your frame perimeter as you expect.

Other issues, like those with bumper numbers, length of short bumper segments, and sufficient backing of short segments that are hanging over ball openings, are all much more difficult and time consuming to fix. If this was the worst problem you had during inspection, then you did better than half the teams out there!
