But, looking at all of these carts, that seems way too small! :?

If it can't fit through a standard doorway, it's as good as useless--you may need to get through that at a demo, or to leave the classroom/build area. Now, your standard 28x38 robot with a full set of 2.5" thick bumpers will go through that at 33" (with about 3" to spare, IIRC). So you may actually be too big if you go 5" on each side.

Your best bet would be a platform just about the size of the robot with bumpers on (note: include a lip to keep stuff from coming off, and rails to put the robot wheels off the platform, or chocks so the robot doesn't move) with a storage area below for batteries and quick-fix tools. Doesn't have to be terribly high, or terribly complicated.
