Colour Recognition

[reidmc]

Thanks for the response, I read a few other tutorials and I understand the concept now, I just need to know how to technically program it.

I can find examples of what I need but none of them have notes. could some one break down the major part of a colour reading program and tell me what each part does?

Do you have access to the 2012 LabVIEW software package for FRC teams? There's a vision assistant program included. It lets you plug together various functions for detecting and analyzing colors and objects.

What camera are you using? How are the four motors connected to the four wheels, and what sort of wheels are they?

Yes I do have access to the 2012 frc package according to my teacher. Ill try to find it.

The cameras are Axis M1031-W with a ring of lights around the lens. On the bot Im working on there is one motor for each wheel (mechanome I belive was the phrase my teacher used) and the wheels are "omni-wheels" (I dont know if thats a technical term or a class nic name)

If thats a problem there is another robot I could use that has a pair of motors for a pair of wheels and has traditional wheels.

EDIT: Found the example, trying to make sense of it.

You're in luck. The WPI function libraries for FRC support the Axis camera communication protocol. You'll have to follow the documentation for setting everything up properly before it will work; look here and find the section dealing with the camera. You should be able to use the Vision Assistant to play with image processing and figure out a sequence of steps to find the color you want to follow.

The 2012 Vision Whitepaper posted on the firstforge site might be helpful.

Your drivebase sounds like a mecanum setup, with diagonal rollers on otherwise conventionally-mounted wheels. It's capable of moving in any direction at any time, either while facing in a constant direction or while turning. Again, you're in luck. The FRC libraries support mecanum drive directly. Just supply a number from -1 to 1 to control how quickly it moves forward or reverse, another number from -1 to 1 to control how quickly it moves left or right, and yet another number to control how quickly it spins counterclockwise or clockwise.

Thanks for the help, I tnink I can manage from here but Ill post if I hit another roadblock.

We'd all love to hear how you made out, once you're done.
