    Is it this kit?
    Does it employ one of the diagrams below?
    I'll not say it's suitable for your project, but:
    You'll need coloured filters in front of the phototransistors, and perhaps coloured LED's as light sources. A robot based on this kit (with no modifications) will zig-zag along the line.
