Bumper backing can be exposed, but facing towards the robot. Does this need to be covered?

My definition of exposed would be if the plywood is visible when the bumpers are installed on the robot. Our current bumpers have quite a but of exposed plywood on the side facing our robot. They are supported in the back by a piece of 1" tall plywood attached to a piece of 1x1 aluminum box. The brackets holding the bumpers in place are fairly small and the fabric currently only wraps around about 1-1.5" around each edge leaving between .5" and 1" of backing I would consider exposed on either side of the supporting frame member.

I agree with your conclusion, but am not fond of taking risks when it comes to inspection. Safer to ask the question and find out the answer now.

This is taken from the rules, red highlight is mine. To say that the cloth does not have to cover the back is NOT what is stated in the rules. Please read the rules before making statements.
Steve, please read the current revision of the rules. Revision H of The Robot replaces what you highlighted in red with The cloth must completely enclose all exposed surfaces of the BUMPER backing (plywood) and cushion (pool noodle) material. (Italics are mine.) That's what the original post quoted, and the interpretation of "exposed surfaces" is the question.

I don't think the part of the bumper that is against the robot frame is "exposed", but I'm neither the GDC nor a robot inspector.

Re: <R07>E Bumper clarification

I really believe they mean that the back of the BUMPER needs to be covered with fabric. If you look at the rule and shift your eyes over to "enclose the BUMPER backing (plywood)" I think this very clearly stated that the back of the BUMPER(part attached to the FRAME) must be covered.

This is how our team views is, this is how we made it. If you look at it from a safety point of view; having the back covered helps prevent splinters when dealing with the BUMPER.

You guys need to keep up on the updates. See Alan's post right above yours.

That said, any team that opts to cover the back will not be declared illegal.

Re: <R07>E Bumper clarification

Steve, don't try to fail a team who doesn't have the backside of their bumpers covered. http://forums.usfirst.org/showthread.php?t=14610

Re: <R07>E Bumper clarification

After reading the update number three I will say that the GDC means that anything that can be seen from the audience should be covered. I take this to mean that the backing now does not need to be covered.

Note to self: stop building and read updates faster.
