finally got him moving. he's not exactly the brightest bulb, but i'm proud of him. I had to redo the Tamiya gearbox down to the 203:1 from 58:1 to better work with the controller. figured i'd leave his mistakes in the vids to mark later improvements, so don't make too much fun of him, he's trying. also i'm marking him as complete, simply due to his completing his basic designation, but i'll definitely be making some tweaks.

this is my first real robotics project, after finding this site and learning about the wonders of PICAXE. It's not my first electronics project, nor my first programming project (although I havent really done much since the late 80s)

Tamiya tracks and dual gear drive along with an Erector/Meccano set. Basically it's a variant on the "Start Here" bot just to get into the mindset of making these work. Much more is planned.
