4 motor Mecanum wheel code request

[inventor1254]

First thanks for the quick replies!

I have to say I'm not too sure what strafing is (googled it a little) I'm guessing thats when you use the rollers on the wheels to make the robot go sideways. I don't know too much about driving systems or their different advantages, (mostly math and lower level languages) but thats a different topic.

I would first ask for just the basic tank drive, just because we lost ours from last year, only with 2 motors per side. (I know LabView has a basic vi of the tank drive, but like I said most of my experience is with things like C++, too me Labview is just confusing.)

With the tank drive (y axis on 2 joysticks) leaves the x axis unused, I'm assuming that is where you would want to use the strafing [moving perpendicular to the wheels (correct me if I'm wrong on my vocabulary here]) but that leaves open 2 possible movements you can make with the joy sticks (that I can think of) one where both joy sticks go outward from each other, and the other where they point inward/toward each other. I'm not too sure what that would do or how those "gestures" could be utilized.


What I'd like is some thing that can utilize as much as possible, but still be simple to use. and thats where I have trouble with LabView is that seems like a lot of if statements, and I never quit get how those work.

So could we get a few basic examples, one with basic tank drive for 4 wheels, and one with the strafing. Plus maybe the strafing on one and tank on the other, but really this isn't my area of expertise. I'm only able to really talk with my team during the week, and am not sure exactly where they were going with this.

I'd just like to see a couple of different ones that I know work so I can kind of figure out how they work and how to edit them, because at the moment I'm not too sure what would work better.

Again thanks for any and all help, and all help already given! I don't want to ask for too much but I don't know too much about the drive system aspect, and if we were doing this in C++ a few of our teachers and I would probably be the main programmers, so we're kinda in the dark!
