Long-orientation octocanum.
9:1 reduction p80 CIMs direct driving fixed AndyMark HD 6" mecanum, in turn driving articulated 4" performance wheels with roughtop tread via gates sprockets and belting. The performance wheels were at an additional 5:1 reduction, for a total of 45:1.

We love the drive -- it's robust and (relatively) elegant, fast and maneuverable, has monstrous pushing power, and I love that it's chain-free. We're looking at doing something similar with smaller traction wheels -- perhaps 2" colsons -- in the off-season.
