Colour Recognition

[reidmc]

Hi, This is my first post on this forum, so if there are any forum rules please just fill me in.

I am in a grade 11 robotics class and up until a short while ago I could follow everything and do all the assignments. Then my teacher gave me an assignment to make a program to make the robot follow a specific colour, I've done a program that allows you to drive the robot from a joystick and other basic beginning programs but I don't even know where to begin with this, most of my classmates are oblivious or dismissive ("oh yeah that's really hard but I'm busy playing video games in class")

I have never done anything related to robotics before (though I have done some computer programming) so please do not make too many assumptions as to what I know.

If you need to know anything about the bots I can find that out too.
