Well, you can have wheels hanging off the side of your robot, you just have to support them well. Like at Cal Games in California, team 254 had joined up with Kingman to build another bot over the summer, and it had 6 or 8 wheels, i forget, all of which were outside the body. Of course to prevent damage to them they had sheetmetal guards. But.. they had 2 bearings on each wheel axle, with a sprocket in between, and the wheel off to a side. And it worked, WELL! That bot was high quality, it was so fast it was seriously getting air off the ramp.
