Green and pink painted robot (a good defence?)

Well lets assume a robot on the opposite alliance has made great use of the camera and has a game winning auto aim and fire algorithm.
Would painting the robot green and pink provide some sort of defensive advantage?

Re: Green and pink painted robot (a good defence?)

It does not mention colors. the devices listed give unfair technical disturbance or blind out the camera completely. The green and pink paint is not going to interfere with the camera, it will simply confuse it.

Re: Green and pink painted robot (a good defence?)

The last example i.e. changing the robots color is somewhat clear. In past years this has always been interpreted to mean you can not mount target lights or paint your robot in such a way so as to confuse your opponents vision systems.

I would consider a painted stick a device. Granted, its a very simple device, but it has a purpose and therefore is a device.
My opinion though.

Re: Green and pink painted robot (a good defence?)

I would say that paint is a decoration, not to mention the specific example of color-changing robots. And confusing a camera would certainly interfere with its accuracy, which was probably the whole point of using a camera.

Re: Green and pink painted robot (a good defence?)

I wonder how this will impact the traditional Pink and Green teams. Moe has been green for years, do they have to mute their color this year?

No, because the vision systems (well at least from what I discussed with the mentors on my team) are going to be looking at the color pattern of the post, not just say the color green (365) or pink (233).

It would be interesting if they played on the same field though

Re: Green and pink painted robot (a good defence?)

this poses a problem for our team because out team colors are both pink and green. the material given out in the kit for the top of the trailer is the same color and material that we have been using for years on our bumpers. does this mean that we are going to have to change our bumpers to a different color??

What I meant was make it more specific to tailor to actual painting of the robot. As it is right now it only mentions the changing of a robots color, and nothing about robots of that color initially.

Hmm, you should probably ask in the Q&A about this. To play it safe I would suggest just making your bumpers one solid color this year. That way no one can accuse you of interfering with their robot.

Re: Green and pink painted robot (a good defence?)

A properly designed vision system would reject an all green or all pink robot (both colors aren't together). They would also reject a green and pink robot, because the colors wouldn't be at the right height.

I think very few teams will have a vision system that does both of those things, but it shouldn't be possible to mess up the best teams through such means.

When the vision system first came out MOE tested this many, many times and found no problem with the camera attracting to our bot's or anything else that it wasn't programed to, now that was a few years ago so I can't speak for this years cameras.

Re: Green and pink painted robot (a good defence?)

Hi...

In 2005 (our rookie year) our robot was painted Yellow (as its been every year since) We did'nt know until we got to the regional that it might be a problem. Luckly it was'nt and we were allowed to compete in our colors.

Vision colors in 2005 were Yellow (if i remember right for the corner goals)
and Green for the Vision tetras. We had one of the better autonomous camera
programs and accually almost scored on the center goal in autonomous.
