I don't have any good pics of 33's bot, but you can see everything above the bumpers in my WAI pic. Hangs really quickly from the vertical bar. I think Daniel Ernst has some mixed in with pics from Kettering, Troy, and MSC. He posted a link to the MSC ones
HERE, the best ones of our bot are:
Hanging
Driving
6wd, center wheel articulated. Normally drop-center but the center wheel can come up as much as 4-5"
front 4 wheels are AM Plaction wheels
rear 2 are omni wheels
Even though it might not seem obvious from the picture of the underside (hanging), all wheels are driven. 4x CIM through AM Shifters, ~5 and 12 fps.
Claw - Hangs quickly from vertical pole and also pushes center wheels down (they are not actuated other than this)
Pincher-type ball magnet, on a floating assembly, sprung down to go over minor terrain changes like the small bump by the towers and such
Variable-distance spring kicker, motor recoil.
Cool lights to show off during tower-hanging, doubles as feedback to driver and coach.
