hi

i am from team 3132 (AUS)

i was wondering what are people using to keep the bumper connected all together.

and how many layers of fabric are we allowed to use for the colours..

Re: Bumper Color
 

It practically says all you need to know right in the manual, the part about bumpers (don't have the time to pull it up and find the exact one).
Plywood backing, aluminum angle (optional, but really helpful) for the edges of the fabric, screws/nails to hold that.

Unless you're talking about attaching the bumper to the robot. In which case we're doing bolts and wing nuts.

You really only need to use one layer of fabric for the bumper fabric. I don't remember any case where a bumper has had any problems (puncturing, tearing, anything) with the fabric. I don't think there's a rule stipulating how many layers you can use, but one is enough.

Section 8, <R07>. Read it thoroughly; it impacts your frame design too.

As for how many layers of fabric you can use: if you're using more than one, and you don't have bumper covers, you have too many. It's quite common for bumpers to go a full season and never need patching, especially now that all robots have to have them.

Remember, for the colors, you can either have a second identical set of bumpers, or you can have a set of covers that you put over the bumpers.

Rihan,
The bumper sections do not need to be attached to each other as long as they are attached firmly to the robot frame. A big part of the bumper check is that there be no hard parts in the corners where the bumpers meet. The diagrams in the bumper section of the manual are very specific about what is allowed and what is not.

Hi Al,
I feel your pain about the bumpers. We were one of the first to use the bumber area for team numbers and team sponsor's logo. It's a great area for the sponor's and robot names. Oh well I will just have to "GO WITH THE FLO".

Re: Bumper Color
 

I was thinking like... 2 yards of each color? Which at Seattle Fabrics would be 72" x 60" wide. Would that not be enough to cover everything?

Re: Bumper Team Numbers
 

I see folks are doing screen printing of team numbers on bumpers. Has anyone found a vendor of pre-cut numbers in the 4" height and 3/4" stroke width requirements?:)

Re: Bumper Color
 

Which blue is everyone going with, that is closest to the FIRST Logo? My supplier shows a Royal Blue, and a Mariner Blue. They look the same on my monitor.

Re: Bumper Color
 

How much is left over after making the bumpers?
