how well do the sensors pick up color?

not to sound rude or anything at all, but why should we change our colors that our team, and others have used, since 2000 now? also any team that has red or blue can have the same thing happen and those are very common robot colors. I had another question, will the sensors see other colors that are close to red, blue or green and mistake them? if that is the case then many team colors might have to be changed on there bots this year


Once again I am not trying to sound argumentative or anything I am just trying to get a good interpretation of the new rules and if our color might cause a problem on the field then it may have to change.

We have to change the robot colors because it's the rule. It's not like the average team has already build the entire chassis, drive train, and has most of the plexiglass colored already, and now they're being told they can't use that color. It's not really too much to ask for from the refs to tell you not to use a certain color on your robot, is it?

I suppose the trade off for not having those colors available for teams is that the field won't be colored mustard yellow, or any other hideous shades. Besides the RGB spectrum is big, can't we all just share nicely .

Once we get a robot running though, i guess my team will have to see how the colors interfere. My teams shirts a shade of red not that far from what is used. If enough of us clump together in the stands, some robots might do funny things.

From what I've read about the CMU in the past, I think it just looks at the entire picture, finds a color, and feeds back the coordinates. Simple solution might be to use an IR ranger (or Ultrasound) if you can get it to work, so that you can set maximum ranges.

What I'm wondering about the cameras is how big of a deal would ambient light have on what it picks up as a set color? Say at home in what ever setting you are working in, say the correct green is defined at 3.5<x<3.7, or around that range, but in a match for what ever reason due to lighting used there the threshold gets knocked up to say 3.9<x<4.2? it will become hit or miss at times.

I know its kinda specific the ranges, but chances are if not the robot may track anything that could be considered at all greenish in its visual range

I'm wondering if the color sensors and "vision tetras" are another addition to the kit and rules that will be like last year's IR stuff, and cause thousands of hours of peoples' time to be spent trying to make them useful in playing the game, with little success. I guess we'll find out in a few weeks.
