Team 1058 has a simple but working rptotype drive system, jsut to proove that its possible with mecanum, and that you only need a GC of about 6"...

Watch at the end and we can actually dise shift on the hump, giving us the ability to move out of the way if someone tries to prrevent us from going over

Re: Macanum ability to climb ramps
 

We're not as as far along with evaluating the mechanum for front wheels. Our first line-up of wheels went over the bump OK at head-on orientation. However, coming in at an angle engaged the bump so that the front went sideways DOWN the ramp and "failed" to impress us as a possibility. The mechanums at the four corners on a running chassis looked good. I'd like to see it try an angled run at the bump. Maybe it doesn't matter how you start at the ramp since the rear wheels could easily get sideways to force a 90 degree crossing early in the attempt. I'm impressed by the side-to-side travel ON the bump. You can select your descent path to avoid entanglement with a robot in the destination zone. very cool option.

Impressive.
