Obviously mecanums will behave weirdly when one of the wheels comes off the ground, however "Suspension" can also be accomodated through a flexible frame, especially when dealing with reasonably flat surfaces covered with foam-backed carpet. I would suggest completing your frame and giving it a test run as early on in the build as you can. (Note that at least one CD poster has reported mecanums work more smoothly when loaded... so if you are having difficultly with an incomplete frame, bring it up to playing weight for your tests.) We're experimenting with mecanum, too, and based on our previous experience with the kitbot frame we believe it has enough "give" to keep "four on the floor" for most of the competition. And if we're wrong... hey... what's one more problem to solve?
We won't, however, be planning on doing any off-roading with this robot.
Good luck, and post to let us know how it goes.
