Re: Team Pink Can't be Pink
 

I'm pretty sure Pink is smart enough to make adjustments to still have their vibrant identity and yet, not be in any situations that affect vision sensors and targets.
Who knows, they'll probably post something soon once their robot is complete.

Re: Team Pink Can't be Pink
 

That's for the birds! :P PINK will wait for Week 1 or 2 to reveal and MOE...eh...let's say the DC Webcast/Archive will bring us their true colors!

Better watch out...she might be stalking you ;)

-p :cool:

Re: Team Pink Can't be Pink
 

Pink has experimented with different shades of their signature color over the various years, and I'm sure they can find a shade which lets them maintain their identity but which is highly unlikely to cause camera interference.

Re: Team Pink Can't be Pink
 

I'm sure pink will find a way to be pink.

It's not really the pink that'll mess a good vision system up or at least not just pink. A good system should look for pink in relation to green or green in relation to pink for target tracking...

Re: Team Pink Can't be Pink
 

Yes and no... detecting the vision target depends on specifying a range of acceptable colors, and depending on lighting conditions you'll detect various shades of pink. When we did our initial calibration, our light pink sweatshirts passed just fine, but one college mentor was wearing dark pink (darker than the target) and was detected, as was a chair in the room.

Plus, every pink or green blob your robot has to inspect increases the time you have to spend inspecting each image, slowing down your vision system with false positives.

In order to tell distance to target, you want the camera to be low, looking up towards the vision target (giving you an angle, from which you can compute distance easily). with a low camera and a high target, colored robots can easily get in the way.

Pink will be pink and Swamp will be green. Here is what's going to happen...

On Thursday at Florida Regional, The Pink Team and Children of the Swamp with go head to head on the street outside the arena where they are required to track each other and use their telescoping arm/forks to beat the crap out of each other. "No contact outside bumper" rule doesn't exist for this portion. The show will go on for 15 minutes (Oh, there is a $10 entrance fee). I am sure there will be scratches all over those 2 robots and some of the paint will come off. That's where I come in with a can of black spray paint and spray it all over those two robots to make them look pretty. =)

Re: Team Pink Can't be Pink
 

It will be interesting to see if this becomes a problem.
Even more interesting to see how it's resolved if it does.
As has been pointed out, a properly functioning bot will not have a problem identifying the right colors at the right height and in the right orientation and proximity with respect to each other.
Imagine someone's grandma has shown up wearing a lime green sweater and a terribly pink shawl.
Will grandma be asked to leave if she confuses a bot? ;-)

Re: Team Pink Can't be Pink
 

This is one way of telling distance with a single camera.

Another is: As a target moves away, it becomes smaller in your field of vision. Because we know the size of the target, you can tell the distance by how much of your field of vision the target takes.

Re: Team Pink Can't be Pink
 

I think that as long as a pink team member isn't on the shoulders of a green team member or visa-versa they should be fine. :D

Re: Team Pink Can't be Pink
 

The only problem u will have will be rule <R19>

Any non-functional decorations included on the ROBOT must not affect the outcome of the MATCH, and must be in the spirit of “Gracious Professionalism.”

However as long as your robots decorations do not interfere with the match you should be fine. As for rule <R02>as long as you are not intending the decorations to jam or interfere with the other robots you will be fine.

Also another way you can help make sure your robot is not breaking the rule is by rather then painting solid pink across the robot, you can use optical blending to make it look pink. Because it isn't straight pink the robot shouldn't confuse it and yet the eye will still blend the colors to make it look pink to a person.

Re: Team Pink Can't be Pink
 

I like how you think....

I really don't foresee a lot of problem though. To find the target, you have to look for Pink and Green so one robot's color shouldn't mess up vision targets too much.

Re: Team Pink Can't be Pink
 

i dare you...

Re: Team Pink Can't be Pink
 

Deal. =)

Re: Team Pink Can't be Pink
 

It seems to me that if the camera is being used to look at vision targets, there is no reason to have the lower edge of the camera's field of view pointed "down" from horizontal, and if the camera is not looking down, bumpers of the color we have used for years should not be a problem. The upper part of the robot could be a problem if we make it hot pink. I'd like to see a clarification of "how high is too high" on a robot to have the vision target colors and I've posted a Q and A question to try to get a clarification. We'll see if anything changes from the present Q and A response which pretty much says "don't use the vision target colors anywhere on your robot or your body." We may make two sets of bumpers, pink and black, and then use the black ones if required to do so.
