My team (at my recommendation) opted to use mecanum wheels for our robot. This is all fine and dandy, especially since our track record from last year using them really is pretty good. This year, though, I've run into an issue that really perplex's me. When we go to turn, the front wheels of the robot spin one way and the rear two wheels spin the other. (In case you don't know, what should happen is that the two left wheels should spin one way and the two right wheels should spin the other.)
I am very confused because every time that I run through the math to check that the motors should be running properly, I get the corect output, but once I test it by driving the robot, it functions improperly. I am going to do some more testing to check the values to see that they line up with my calculations today, but I'll probably still be very confused. If any one has any ideas and would like to help, I would be most greatful.
Sincerely,
Austin

Austin,
Put the robot up on blocks and tell us what the four wheels are doing when you give it each of the following commands: pure forward, reverse, strafe right, strafe left, rotate right, and rotate left.
That info should be sufficient to identify exactly what needs to be changed.
