Two updates from the Team Cockamamie camp:
1) Rock wall?
Check!
2) Tonight, we let the Garnet Squadron kids drive it in our parking lot for some practice. After several more jumps not unlike that one (which are super fun, so I can't blame the kids), the two sides of the drive system had noticeable camber to them. This robot was not huge on bellypan or front supports for varying reasons; the first thing we'd probably try is more fasteners on the belly pan in the front (the metal panel where the USC logo is) to tie the two sides together better. If we weren't concerned with the low bar or if we didn't use a kicker, we would absolutely tie the frame together in the back as well. And, of course, there's not driving your robot like a raving lunatic.
Just things to consider if you're giving our robot a look while you design.
