I agree with sanddrag, there's no particular reason your bot can't be both holonomic and handle ramps. There are fairly easy ways to accomplish this, either by tweaking some of the details of the holonomic drive itself, or have some sort of mechanism

I think holonomic drives are going to be popular this year, since it's an attractive approach to the problem. Heck, I think the students on my team have thought about it, even.

Test early, however. Holonomic drives can do some weird things.
