Thanks Gary that is very useful. I will do some modifications to my design. I suppose i will have to wait until i have access to a lazer printer before making the board.
I have been working on the next version of artificial stupidity. I will be using 2 IR opponent detectors and 3 line sensors. Was planning to keep it simple but is getting more and more complicated. Will update when i have compiled the necessary parts.
Glad you're still working on it Andy!
Orgiami is likely to remain mechanically unchanged for a while but I will try to find time to tweak the software before the next AWS.
