Sometimes during the eliminations, alliances switch from being red to blue or vice versa, and have to play back-to-back. You'd better be able to change your bumper colors in 4 minutes or less. Last edited by GaryVoshol : 11-01-2010 at 13:41. |

I think no more than 2 a side are necessary and if you use the same one in the corner to hold 2 sides as we did last year 4 total is all you need this year. |

Re: Changing bumper colors
We've used these for a few years now. We tend to use three on each long side.

The specific part number was McMaster-Carr (p/n 98320A140) ![]() They should also mate with AndyMark's bumper brackets AM-0317 Last edited by kramarczyk : 12-01-2010 at 07:32. Reason: added part number |

Re: Changing bumper colors
Our team has, for some reason, been unable to figure out an elegant solution to mounting our bumpers the last few years. I really like this solution, BUT I am unsure how it is implemented (along with the AM brackets) to avoid the 1" hard parts rule. Our understanding is that with the 3/4" plywood, you only have 1/4" left for bolts/brackets etc. which appears to us to eliminate fastening systems other than what is very similar to what is shown in the manual.

Re: Changing bumper colors
Are you fishing for questions? Such as, what if we build two sets of bumpers, one red - one blue? Would they have to be weighed in together, and weigh less than 20 pounds combined?

Re: Changing bumper colors
In the rules <R07> they clearly say you can have 2 sets of bumpers at 20 lbs each. IMO take advantage of the rule and make 2 sets and do a quick change.

Re: Changing bumper colors
No. He's saying that bumper color will need to be changeable within 4 minutes because of the field reset rules.

Re: Changing bumper colors
These new bumper changing things are going to be pretty neat.

Re: Changing bumper colors
I think it is going to be a pain in the butt...
I dont like the fact that we have to change such a large component of our robot to indicate our team color. I kind of wish that they would do something else for that purpose. In the past, our teams bumpers have been pretty much permanant...The only times we ever had to take them off was to weigh the robot, and to get it to fit into the crate for shipping... Now we have to change them almost every match? that just seems a bit rediculous... I COMPLETELY do not trust bumper covers. They seem too easy to remove, no matter HOW you design them...I dont think that capability is worth the chance of a penalty |

Re: Changing bumper colors
does anyone know which blue is required for the bumpers?
I called Seattle Fabrics and they have 2 types: Royal and Navy Blue. Im thinking it doesnt matter, but just wanted to make sure. When we asked, teams that called earlier didnt know and they themselves have not been told by FIRST if it had to be a specific one. Dont want to base it from the video and the video alone. |
