What r possible drive systems under these circumstances?

Okay so basically the game contradicts itself. Slippery floor, slippery wheels. We actually had the polymer "regolith" in our room..it was used in one of our bathrooms. At first when you move your hand across the surface it feels very bumpy. But when we moved the wheels across the surface there was O friction, a concept that is hard to imagine unless you actually try it out for urself. It comes down to who has a good drive system.....which is?
Also for those who who still need help trying to figure out the substance...it is a polymer..glass liner is what it is called..it is used for bathroomwalls..not sure if it is at home depot.....
