Bumpers

So one of the mentors in our team came up with an idea. When the robot is climbing the pyramid the bumper will get in the way. If mechanically the robot were to roll up the bumper while in the air, no longer on the playing field, would that be a volation of the rules?

Really appreciate any responses.

Re: Bumpers

Bumpers may not articulate in relation to the frame perimeter, however, there is nothing against having part of your robot not be covered by your bumpers. Remember, you only need to have 8 inches of bumper on each side if each exterior corner.

Yep, sorry.

BUMPERS may not be articulated (relative to the FRAME PERIMETER).

Re: Bumpers

My team was wondering if it is legal to have diagonal bumpers. When viewed from the side they would look like this:
_____
\ 4118\
.\_____\
as opposed to this:
______
| 4118 |
|_____ |

Referencing R24, I think that it would be difficult to achieve that shape while still using

A. be backed by ¾ in. (nominal) thick by 5 in. (± ½ in) tall plywood or solid, robust wood.

That is just my take on it. I suggest you submit that question to the Q&A.

I see no rules prohibiting that, assuming your FRAME PERIMETER is also a parallelepiped as drawn. That is, the bumpers must follow the FRAME PERIMETER.

Re: Bumpers

I think the diagonal question was the side view of the bumpers, not the top view of the frame. If that's the intent, it would be hard to deal with the corner protection requirements.
