does any one have a working holonomic mecanum setup?
 
i tried to stay far away from the holonomic drive, i guess i would have to use it; my possible short cut ways cant work lol

i really dont understand mecanum cause i wasnt on the team of that year we used it
so can some one help drop some incites about setting up;
magnitude rotation and such has me like :confused:
thanks in advance

There are quite a few other threads that discuss this in detail. Search.

Have you asked your teacher/main mentor at all? I know for a fact that he knows what he's doing. Just ask him about your 07 bot.

From the same team here, our problem's changed a bit.

The basic forward/reverse movement works fine; but when we try to rotate, it instead strafes, and vice versa. We're using the Holonomic.vi that came packaged with the code and the wheel orientation is correct as well. Help would be appreciated, thanks in advance.

It sounds like you have your PWMs swapped between your left and right wheels on either the front or the back. Make sure the code and the wiring match each other.

If I understand correctly what you've said, everything is working, so why can't you just switch the strafe and rotate wires "wires" in LabVIEW ?

you can switch the rotate and strafe coming out of the joystick

I got mine working, but i had to make a home-brewed mecanum drive code.

Has anyone tried the updated mecanum VIs from LabVIEW update 2.1?
