Programming Mecanums in Labview

[Hadi379]

Alan,

Well, as of right now, we are able to drive forward/backward, strafe in all directions off of joystick 1, BUT we have no CW/CCW rotation. I was attempting to get the rotation from joystick 2. I'd like to paste the code here if you would be willing to take a look at it, I feel like I'm making a simple wiring mistake.

Also, when we run the motors, the transmissions make a sound like their fighting themselves, kind of like a jittering motion. Is there anything I can do to refine the program?

Thanks for you time.

Before investigating software, this could be a simple mechanical issue. If you can't make your robot turn under its own power, you might have your wheels swapped.

Can you easily spin the robot by hand when its motors aren't running? If so, you definitely have your wheels swapped.

im pretty sure the wheels are arranged properly, plus, if they weren't, would I still be able to drive in the directions we've already achieved? We just can't get the robot to rotate cw/ccw.

Yeah, if your wheels are the wrong way, then you could still strafe and everything, just not spin.

Well, I'll have to double check them this weekend, but we arranged the wheels exactly how AndyMark recommends in their drawing...I'll let you know, but I really think it could be a programming problem...I'll post code later tonight if anyones willing to glance at it.
