1 - Outer ring to retain whatever we decide to sweep since oil wasn't feasible option
2 - Stationary base that is the part getting swept
3 - Rotating base that has mechanism and electronics mounted to it
1 - Base layer
2 - Layer that has a slot for ball bearings
3 - Layer with the outer ring pieces and the rotating inner circle
4 - Outer ring to retain items
