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.

A while ago we showed off the prototype/demo for the All-Seeing Eye, and from the positive response it got we decided to bring it back as An Actual Thing. We even mounted it to a DragonTail, and let it go for a spin around the office. Check it out:

Two sensor modules, two LCDs. I'm sure there's some kind of joke in there waiting to be made, but I can't quite figure it out. So instead, I'm going to go and pour some maple syrup onto my bifocals.
...Hrm. You know that it's the end of a long week when something seems funny inside your head and nowhere else.
