2/11/10 - oops typo on the first post, its 3 IR's per side!!!
This is my Microrobot Robo-Lefter kit robot.
Its a pretty good wall follower type
maze solver robot for the price.
It uses a Atmel 103 micro and
6 IR sensors, assorted indicators, with a ISP programming port.
In fact I was so happy with it, I bought a second one.
The old one I added a front bumper to, so that I can run it at full speed without fear of crash damage.
