So sorry for not posting, I've been on vacation for the past week. And, yes CLGfive, you are correct! I am working on my third build of Gearbot, and its coming along great. It's going to take a while more, maybe a few weeks to complete. I am going to take apart my Treadbot, but only after taking another, better video of it doing multiple task. After that I am going to work on another Ballbot, a better one (of course).
