View Full Version : Simple Mecanum Question
I have been searching around a bit for mecanum drive examples. For what I have seen I can use the Holonomic Drive VI that is included in WPIlib.
If I use the cartesian VI I just need to plug the X and Y axis right from the Get Joystick and it should work?
Searching has been providing me doubts :(

Some of the posts in the thread you linked to were likely made before the Holonomic - Cartesian VI was released. That VI was only included in the latest Labview update. You can see users discussing it at the end of the linked thread.

You need to decide how you will control the robot's rotation. If you use a separate joystick just for that, or if you have a joystick with a "twist" function, then the X and Y axes are all you need for speed/direction control. The thread you referenced has an example of "tank drive with strafe" control, which is another way to do it.
Oh well... So if I have 2 joysticks I just plug X and Y from one joystick to the corresponding X and Y in the VI and I plug any of the axes from the second joystick in rotation and it should work perfectly?
I remember trying that and motors didn't move...But when I changed to arcade drive...they did. :(
Also, if I plug in the gyro into the cartesian VI it would let me have something similar to a driver oriented drive?
