With the current setup it pretty much just looks like you're needing 4 extra pistons for not much in added features.

So basically do you need 2 speeds when in each mode? or will 1 speed optimized for each mode work.
The gearing ratios are in limbo because it was calculated to speeds for the specific gears. The tractions drive at 2ft/s with 60 ft/lbs of torque and the omnis drive at a max 10 ft/sec. For the prototype the team is only putting 2 modules on a frame and putting two tractions in back and with this configuration you could actually run it and have an effective tank drive with some additional torque benefits. The gearing allows for an even bigger ratio between traction and omni.
