Using 3 infrared sensors in front, the robot can determine when its on course and when it's veering off course. The 3 infrared sensors, also, help determine when it's crossing an intersection. Original plan was to be wheel driven but discovered using tracks I could more easy adjust for course correction without moving forward. Controlled by ATTiny2313 programmed with the parallel version of the Ghetto Programming found on instructables.
I'd like to see more details about this build. Do you have a schematic? What about future plans? I often have problem driving the motors and the microcontroller from the same 9V (when the motors switch the power dip sometimes causes a microcontroller reset). How did you get around that?
I started out programming AVR chips with the same DAPA programmer you mentioned. I would highly recommend saving up for an AVR Dragon. You can do high voltage programming in case you set the fuses wrong. There is also hardware debugging with them which is really nice!
yeah, same, a little vague
