Re: Mecanum Java Code

First, I would make sure you have the PWMs mapped correctly. If you are sure these are correct, it will make debugging everything else much easier.

Also, if you haven't already, put the robot on blocks so you can see what the motors are doing without having it try to drive around.

My guess is that you need to invert some of the motors. You can do this either in code (using myDrive.setInvertedMotor()), or by reversing the polarity of the wires that go from the Victor to the motor. When you push the joystick forward, all the wheels should move. If they don't you either have a problem with your joystick axes (what joystick are you using?) or your motor controller. Once all 4 wheels are moving when you command the robot to go forward, invert all the ones that are going backwards.
