To add on to what John said:

1. When using 4 motors, it is lighter than last years system (It is actually geared so it will still work if we decide to not use the minicims)

2. It is now a single stage reduction rather than using a tough box nano.

3. The modules have gotten smaller because we are using 2 inch colson wheels.

4. The piston is now a 2 inch stroke rather than a 3 inch stroke with the ports rotated. This actually allows our frame dimensions to be much more flexible than last years design.

5. We had issues with last years system with the bolts on the modules backing out (especially at the rumble, where we had one bolt back out enough to prevent us from using the traction wheels after lunch). To fix this, we are switching to retaining rings.

6. The 4 inch mecanum wheel allow us to make the traction wheel even closer to the mecanum wheel, making the chain length even shorter.

7. The modules are now made out of 1/8th sheetmetal instead of 1/4th plate, allowing us to use our sponsors turret punch. This should be faster and more accurate than trying to manufacture it in house.

8. The frame has the battery box built in, in order to be more robust than last years system.
