Re: More line tracking videos

This is 1646's linetracking kitbot. We built the mostly standard kitbot and attached two of the photoswitches to the front.

We wired power and common (brown and blue) to a 20 amp breaker on the PD board and spliced signal from LO (white) to a PWM cable which got plugged into DIO ports. From there it was just some code to keep a short memory of what sensors was last on the line so we could try to turn in the correct direction when we lost it.

If you have any other questions about how we built it I'd be happy to answer them but it is nothing special.
