Is this a legal bumper config?

[Bob Steele]

Just a word of warning .... legal or not...
High bumpers can cause some real issues during gameplay.
Most robots will have low bumpers...

I am sure some other teams on CD can discuss the implications of really high bumpers during game contact....

And don't forget the new rule this year, if your bumpers go out of compliance (e.g. become loose and sag below 2") you get disabled. Ugg.

Also, please bear in mind the vast difference between "frame" and "FRAME PERIMETER". The latter is very specifically defined, and that's what you MUST protect with BUMPERS, not the "frame" of your robot.

@DonRotolo - Does that necessarily mean completely covered though?

Currently the bumpers are planned to mount with C-Channel attachments that are then pinned to the 16th" seen in the photo. We can also (and probably will) move the bumper down 1/2". I'm inexperienced with bumpers, so I don't know if these combined supports would be enough.

@John - We're using 2 pieces of C-Chanel connected to the 16th inch by 2 aluminum pin connectors each, would this fall into the 1" angle you meant? I would assume they could take some sheer stress, though not to large.

@tavar321

Your frame perimeter is all that matters for this rule. Your actual frame can be exposed above or below the bumper zone.

Judging by your photo (and assuming your bumpers are the legal size and weight), you are legal with regard to the bumper height. Since you did not show your whole bumper or frame perimeter (e.g., cutouts in the frame or how far your bumpers cover each corner), I cannot tell if you are 100% legal.

If you intend to have full coverage of your frame in accordance to the rules, then your bumpers, as shown, would be legal.

Can you do a simple sketch to explain how the C-channel will pin to the 1/16" metal?
