Hi guys.... Finally today arrived the last order for this robot... the wheels and the caster.... I took me 2 night of CAD-ing... This is my first entry and I hope that you'll like this... I made this robot based on ermicro schematic and tutorial... http://www.ermicro.com/blog/?p=1097 I used near the same things excepting the transistor... I'm using two 2N2222 transistor which allows 800mA on its collector... So the basic ideea is to follow a black line ...
