It was something I was told by some mentors but have now had cleared up by several members of CD. They were concerned with the loss of power due to the inefficency of running 2 CIM's on the same shaft since the CIM's have very slight differences in preformance curves due to differences with wrappings and the fields within the motors themselves. They had expressed concern over loss of preformance which the reason for the 4 transmission. In addition it was CAD practice so I took the transmissions as a challange to attempt and create a 2 speed transmission cheaper and lighter than (1/2 of ) a AndyMark Supershifter. In reality the design will probably use AndyMark Supershifters because they are much easier to obtain then it is to manufacture custom gear boxes with little experince and limited time. The 4 transmissions would be useful if in the future the team used this platform and diecided to exchange the omnis for mecanum in which case 4 gearboxes would be nessecary. Those are the main reasons for the 4 transmissions.

A fair amount of discussion has already taken place here. This is a newer render.

What CAD software did you use?

Autodesk Inventor Professional 2012
with the lovely education watermark on the printed drawings.
The rendering is just in Inventor Studio, haven't gotten around to learning maya or 3d-max enough to render the image in either of those suites.

Well, I must say that is pretty sweet.
