Go to Post I've been inspired for real engineering during the build season and on the playing field, but the inspiration I found in the pits is often for creative thinking and intuition. - artdutra04 [more]

Could you provide more information (pictures or CAD models, maybe?) on your 2013 and 2014 drives?
I dont have easy access to all the CAD right now but here's some more information on the two drives.

2013:
6 wheel WCD with two speed 4 CIM custom shifters geared for 9/19 fps before frictional losses. The wheels were 6inch custom 3d printed and if memory serves they were 1 inch wide. The robot frame was 30"x24", dont rember wheel spacing exactly but it was ~11 inches give or take. Here's a CAD render of it.

2014:
6 wheel WCD with two 3 CIM Ballshifters geared to 6/16 fps before losses. The wheels were the 4 inch AM performance wheels and the frame was 23.5"x32" with about 8" between wheels. We almost went with no drop on this but decided to go with a very slight drop to be safe. Wheel also almost made it a four wheel WCD but decided against it. Here's a render of the robot.
