Looking good. Some advice from a sophomore -- think about what happens to your big roller when another 130-pound bot hits that at a 45 degree angle at a combined closing speed of 10 or 20 feet per second. I would seriously consider some sort of crash bar in front of it. Of course, you probably already plan one and I'm just wasting your time, but it was the first thing I thought when I saw your pic. Good luck!
