A butterfly drive is a drive train with four omnis in the corners and then a pair of deployable traction wheels to allow you to drive staiter and not being pushed, while also giving you a quick and nimble drive train with the omni wheels. Most these ive seen drive the two sets of wheels at different speeds resulting in a "shifting" drive train. ALthough some teams (148 maybe?) run all the wheels at the same speed allowing them to have omnis down on one side and traction on the other changing where the robot rotates. Here is some info on 3928's butterfly drive http://www.teamneutrino.org/seasons/...bot/butterfly/

A nonadrive is a butterfly drive but with a center set of omni wheels positioned perpendicular to the other wheels allowing for the whole drive train to strafe from side to side. Heres a video of 148s 2010 nonadrive you can see the drive train specifically at 1:10 and 1:33 http://www.youtube.com/watch?v=_hTyXQUgYLE
