Our robot is 8WD with 3 different types of wheels. We have 4 small wheels, 2 in the front and 2 in the back, that only contact the ground when going over the bump. In the middle-front behind the small wheels we have traction wheels, and behind those are slick(er) wheels, so that when we turn we rotate around a point between the 2 traction wheels.

We found that this drive works really well for going over the bumps. In fact, in auton we go over the bump to the next ball just by setting the motors to a constant speed and waiting for an encoder count. I wonder if 1114's 8WD can do that...
