Re: 6 Wheel Drives Without Dropped Centers

2011: two 4" omnis up front, four 4" performance wheels in rear, roughtop tread. Long wheelbase.

2012: six 8" AM pneumatics, square footprint

2013: six 6" dia. 1" wide aluminum performance wheels, blue nitrile roughtop tread. Very slightly wide-biased footprint.

All three were powered by some variation of the A-M SuperShifter, 2 CIM's per side.

2012 was not surprisingly the least-maneuverable of the three setups, but it still was good enough to get the job done in one of our most productive seasons ever.

The 2013 iteration is very nimble yet able to provide enough punch to apply solid defensive pressure when needed.
Just to clarify for Travis, 48's 2013 drivetrain ran 6-in custom performance wheels with 1-in roughtop tread riveted in place. Due to our relatively square frame, this put our wheel base at 24" between centers (front to back) and about 26.5"-27" between the center tread contacts side to side. It was an all-around quick cycle runner with no problems doing zero-radius turns in either low or high gears.

Our 2012 robot's wheelbase was only an inch wider than it was long, so with the much larger contact patches of the pneumatic tires, it definitely did not turn as well as this year's bot (as mentioned above).
