There are a couple of problems with this design:

1) Compwiztobe is right; the miter gears will lock

2) If you try to turn this assembly, the wheels will try turn in opposite directions (think of a 2 wheel drive turning) and something will have to brake or slip.

3) (i'm assuming you are going to use two of these modules) When all the wheels are collinear, the robot will fall over. If you add casters though, you can fix this problem, but that defeats the point of make two wheel modules in the first place.

4) You won't be able to turn, because unlike regular swerve, you do not have the 4 modules to form a x with the "turn' chain. You could potentially add caster, but again, that defeats the point of making modules with two wheels.

Sorry for being so negative. On the bright side, this is the dedication that makes teams win. Nice job trying to reduce the price, weight, and complication of arguable the best drive train in first.
