Hi I am new here and I just ordered my EZ-B kit and can't wait to get it. I have been building robots on and off for years which my first one was the Popular Electronics Unicorn 1 robot. back in the 80's. My how things have changed since then. My robot I am working on now is 3' tall and is build using the 80/20 frame work, cool stuff (8020.net). I want this robot to be able to run around the yard, so I want it to have tracks. These tracks need to be at least 2" wide so I am looking for something complete with inner wheels, ect. Anyone ever built a track driven robot on this scale.
