Re: crab drive vs. mecanum drive system

My teams have used 4wd, 6wd, mecanum and crab drive. About the only mode we have not used yet is holomonic or kiwi. Many of the advantages and disadvantages have already been covered so I will not repeat them now.

AndyMark is now selling off-the-shelf Swerve drive modules. Not cheap, (cheaper than paying a shop for custom parts) but it gets around most of the machining issues. AM products we have used in the past, traction wheels, mecanum wheels and shifting gearboxes have all been solid.

My personal favorite for general use is the 6wd with center axis slightly lowered. It is quite maneuverable with great ability to push.

I would not lock he team into any specific drive model until you determine how you want to play the game. We are exploring several options so we can pick the type that suits our chosen strategy once the game is announced.
