Try actually adding some mechanisms to that kitbot frame. The COG is so high that it gets scary pretty quickly. We've done a lot of testing the last couple days, and 6 wheel bots long, 4 wheel bots wide, and even 6 wheel bots wide are all pretty darn scary on that bump - the smallest twitch makes them flip over. We're moving on to more exotic drive systems =). You absolutely CAN NOT decide on a drive train without at least building a small trial-bump to play with and see how your bot is going to react.
