Hi everybody...long time reader, first time poster :). I'm jumping into the bot world with a re-build of an old HeathKit Hero Jr.
He has one drive wheel steered by a stepper motor. At the very least a servo would work better than the stepper. It looks like all the projects you all are doing have the skid-steer type drives (like Wall-e) So should I scrap the tricycle configuration and go to 4 or even tracks? I'd like here the pros and cons from the experts!
