Looks mighty slick. Two questions-
-How's traction/"pushing power" in the front/back and side/side directions?
-How's maneuverability?
Keep us posted on how it works out- our team may be interested in that sort of drive this year.

Along with what Tristan said, the frame looks fairly light. I wouldn't be surprised if the frame flexed enough to make do without the drive module pivots. Though, knowing your design skills, I'm assuming you'll have more structure going on top to stiffen the whole assembly, hence, making my point worthless.

Do you plan on rivetting/welding/bolting the frame?

However, I'm at a loss as to how the tensioning slots work. Since the idler moves with the gearbox module, it seems like all you're doing is changing the tangent point of the chain with the wheel. I would expect the idler to move with respect to the gearbox, or to just use an eccentric idler/guide. That could greatly simplify the entire assembly.

Overall it looks very nice and clean. One of the better Mecanum setups I've seen.

Excellent CAD drawing.

If I was a potential sponsor, I would briefly like to see a work flow chart, concepts, designs showing different phases of development.
I would also like to know how the parts of the drive Tran can be fabricated, the work plus cost involved with the machining and assembly.
The possible use of outside services to perform any advanced machining of parts, the testing phases and the redesign phase that the teams must go through. Tie it all up with the learning and skills the students are receiving from working on this design.

This all translates to "what am I getting for my sponsorship dollars and how the money benefiting the students."

(That's just my opinion) Again, very nice design.
