We tested our old mecanum drive on the bridge after covering it with 2009's Regolith material (which, based on cursory testing, is slightly slipperier than the Lexan that will actually be on top of the bridge). The mecanum wheels move across it perfectly well, even from a standing start, although balancing with two mecanum robots was a little tricky and took about fifteen scary seconds.

I'm not terribly worried about the HDPE; people condemned mecanums over the bump in the field last year and that didn't mean anything. We'll try running some tests, but I'm fully confident that suspensions are not necessary to handle HDPE.
