This circuit is used to create a simple "edgebot" sumo robot. Being an edgebot refers that it will repeat the same backup/turn/go forward action when it's single edge sensor detects the edge of the ring. This version of the circuit is quite simple, and always turns the same way.
SparkFun Free-Day Aftermath
Dave Hrynkiw
January 13, 2011
After last year's meltdown of servers during SparkFun's 1st "Free Day", we sent them flowers of condolence. This year, after seeing that little image of a burning computer on their error webpage , we felt he urgent need to send down the entire Canadian fire brigade (yup, both extinguishers).
And who better to put out the fire on that little computer than SparkFun's IT department (you're honorary Canadian firefighters, especially the guy with the toque!).
Went better than last year, guys - you're making progress!
Thanks for sending us the pic, Nate!
