We had originally planned to go over the bump, but ended up not being able to due to geometry, I wish we had gone with smaller and more wheels to enable this. Also, our Supershifters had the wrong ratio for 8" wheels, so the high speed was too fast for our drivers and was thus never used, leaving us with wasted weight and a tad slow. I would have switched the gear ratios to slow everything down a couple fps or switched to a lighter and slightly faster 1-speed transmission.
Did they have an additional mechanism to aid going over the bump? I know 111 tipped up the front of their robot to do this, but I never saw exactly how this was done.

I spent about 5 full minutes looking at their robot, and I now realize I didn't ask about the drivetrain. How did I not do that?!
I can't tell if they have something to lifts their robot or if their sheetmetal frame is just shaped to pop them up and over. 971 and 254 have a little drop down wheel that launches them over, but I can't remember what 1114 does. Something passive would definitely be nicer.
