Good, because I'd hate not to have our Robot Skirt again this year just because the color of the tetras is ThunderChicken Green.  |
Just a thought here. Yes it is LEGAL to have your robot any color that you may want. But, and this is absolutely not an "Official FIRST Position" or anything, just an independent thought (I am allowed to have one per week...
), you have to ask yourself if it is SMART to have your robot certain colors. If you pick a color for your robot that you know is very close to the color of certain objects that will be sought by the vision system, what will be the result?
You know that the vision systems of the robots on the field will be calibrated to look for green. If your robot is a similar hue, then you know there is a significant probability that it will be detected by the vision system of the other robots - INCLUDING YOUR ALLIANCE PARTNERS. After about the second time that an alliance partner robot is prevented from grabbing the vision tetra and scoring bonus points because your robot was a confusing color and distracted their vision system, your team is likely to become a pariah. If I were an alliance captain picking teams for the elimination rounds, I don't care how freaking good your robot may be, I would never ever pick you as a partner if I saw you repeatedly screw up the autonomous period performance of your own alliance. The risk to the alliance would just be too great. There are lots of other implications as well, but I think you get the point.
So, once again, it comes down to a simple question: coloring your robot green (or even yellow, the color of the targets in the goals) may be legal, but is it smart?

I still have yet to even power up the cam, but that should happen today.

For the kickoff demo, the camera was calibrated for the color of my shirt. It was able to properly discriminate between the shirt and the green vision tetras.
