This is a simple obstacle avoider which uses 14M as the microcontroller.
I tried to build as much as I can by myself, and that seems be fine. The PCB is homemade, and it only has got features what this bot needs!
It has got a Sharp IR sensor, and places for a few of other sensors. It moves with 2 modified servos, and for the fashion it has got a little bit of glittering hot glue :)
I have built now 6 robots, and I'm only 13 now!
