Mechanum Problems...

First, since it's so easy to check, and it affects the ability of mecanum (no "h") to rotate, make sure that the wheels are mounted properly.

If that checks out OK, load the default 4-motor tank drive code that came with the Framework. Put the vehicle up on blocks and verify that the motors are spinning in the right direction.

If that checks out, post your code for review.

Last years mecanum code was slightly more advanced than this years. Last years code allowed for a scaled (X,Y) cartisian input. This year the mecanum drive requires a direction and magnitude vector to operate. Some simple geometry (A^2 + B^2 = C^2) can get you back to that system, but you need to provide a direction and magnitude for the the new mecanum version to operate.

Cartesian is still in the holonomic vi nothings changed
