This is the current state of my attempt at a solution to the maze. Here you see an 8"x8" Aluminum plate with wheels. Across the top I've placed equipment to try to get an idea of how my space allocation is doing. The left middle board is Eddie Wright's ATMega32 DevBoard. Above and below that are my line sensor comparetor boards. (They translate signals from the IR phototransistors into a hard 0v or 5v signals for the microprocessor, though Eddie tells me I probably could use the signals directly) The right middle board is my H-Bridge circuit that I had made up using ExpressPCB. The chip is 4 1A half H-Bridges. Also note that I've pasted encoder stripes on my wheels, though I don't yet have a circuit to measure them.
