Re: Changing bumper colors
We ordered the royal blue by chance, however, a bunch of teams called and ordered Navy.
If Seattle Fabrics is the official vendor for the bumper fabric as they have been the last several years, FIRST should let them know, to save time and hastles for other teams. |

Re: Changing bumper colors
In my opinion creating different color slips to go over the bumpers (as mentioned in the manual) seem easier than creating two separate sets. This enables you to do a fast change, plus you don't have to go through the hassle of creating and testing both sets.

Re: Changing bumper colors
So navy blue? Correct?
And what are the pros. and cons. of the cover slips vs. individual bumpers for the different colors... Last edited by Robotbug : 11-01-2010 at 21:54. |

Re: Changing bumper colors
would using zippers be legal as a means of attaching bumper covers? Looking at the rules I can't tell if they would fall under the "hard" or "soft" section of the bumpers themselves and am therefore unsure as to a legal location.

Re: Changing bumper colors
It sounds like a great idea, they would be more than strong enough. I believe the zipper would fall under the hard part of the bumper though. Assuming you designed the bumpers right, this would be legal.

Re: Changing bumper colors
In 2007 and 2008, we did alternating bumper colors to show which alliance we were on. It was fun, and the announcers had a great amount of fun with it. If they are designed right, it isn't that hard to change them, especially if you have one person per bumper. During Quals, there is usually enough time between matches to make the change.

Re: Changing bumper colors
Industrial strength velcro should work pretty well for bumper covers. We have used it for side panels of fabric on our robot and it takes some pulling to get it off. Then you could have have one set of bumpers and fabric covers. We often use fabric on our robots. We use the Cordura nylon in areas that we want to deflect sharp arms from other robots or mechanisms that unfold to guide a ball. There is velcro that you sew on and stuff that has an industrial adhesive. Sew the velcro to the cloth and use the adhesive type for sticking it to metal. Go back and rivet the stick on stuff if you want added security. Use velcro as wide as you can for more strength. It won't go anywhere.
We don't have a trailer or large storage area so I would rather do anything NOT to have a duplicate set of bumpers kicking around the pit or workroom. They are difficult to store and take up a lot of space. Now what would be cool is to get that programmable cloth and program in the color. Anyone have a few thousand extra just for bumpers? Ann |

Re: Changing bumper colors
I did work briefly for a company that made thermochromic fabric that was electrically actuated. Too bad it uses alot of power, as that would be pretty cool looking.

Re: Changing bumper colors
To keep everyone aware of changes in the rules this year...
<R15> Teams shall display their team number on the BUMPERS in four locations at approximately 90-degree intervals around the perimeter of the ROBOT. The numerals must be at least 4 inches high, at least in ¾-inch stroke width and in a contrasting color from its background. Team Numbers must be clearly visible from a distance of not less than 100 feet, so that judges, referees, and announcers can easily identify competing ROBOTS. |
