This one?
Well keep in mind that, while more wheels will keep the tread pattern from wearing down as quickly, doubling the number of wheels will give only a very minor improvement in traction since, while it is simplified, friction very closely equals N*mu. Having a wheel on each side will significantly increase the torque required for pivoting and it will probably take a minimum of a quarter of a second or so to rotate a module 180 degrees.
