Spoogy,

This seems to be a very straightforward algorithm that has been coded many times for the Lego NXT. Perhaps you can check google to see if anyone has a script already built that can do this. Lego even comes with a line following script that you can perhaps modify.

If you're using LeJOS there must certainly be algorithms written to do such a thing. Perhaps some of the more lego centric sites like

How to Line Tracking with LEGO Mindstorms + leJOS

Tue, 30 Nov 1999 00:11:00 EST

Hello,

I am trying to write an algorithm for Line Tracking. But I have no good ideas.

What do I have:
- LEGO Mindstorms
- NXT (leJOS: kind of JAVA)
- Driving Robot availible
- ColorSensor in Combination with LightSensor
or
- ColorSensor in Combination with CompassSensor

What do I want:
- Following a path
- Turn left or right on Crossroads (They are coded with colors 6cm before the crossroads appear)

My Idea:
- While (Black) driveForward
- CompassReset (to Zero)
- if (white && CompassSensor!=0) rotateTo(0)

Anyone any good idea? Thank you very much!
