Well, we put the omni wheels in the back for 2 main reasons... One was that we found they spun better under a larger load (which we had in the back) because we made the neoprene and delrin disks stiff so they wouldn't be free spinning unless there was significant torque from our drive train to make them and with more weight on the wheels they spun better. (Having a lighter load we found caused the robot to bounce when driving straight where as with the heavier load they rotated smoothly) Also it was important for us that the back of the robot was the part doing all the turning since we were a small ball robot and the roller was in the front. Rotating around the front wheels allowed us to stay in front of the balls.
