You are correct, a number of the hyperlinks in the PDF are outdated. You can find the new versions of all of those tutorials on the main FRC page. Sorry for the late reply!
We have noticed (and fixed) a few problems in the sample Holonomic Mechanum Cartesian code:
1. The joystick inputs have Rotation, X and Y messed up. We had to fine-tooth-comb which should be hooked to what, but once we found the right VI, it was not difficult.
2. The motor comments that specify which motor gets which port has an error which prevents lateral X motion. We switched the wires between port/motor 1 and 3 and now it works fine.
Not sure how this slipped through, I hope this helps other teams (particularly newbies) to get their mechanums working.
We are Rookies and by rookies I mean rookies. We are trying to use a mechanum robot but dont know where to even start. Is it as easy as picking the mechanum drive from the drive types. And if it is does it work or are others having problems?
Yes, it's mostly that easy, but be sure to set your wheels to look like this image, or it won't drive right. Also check out my comments above on the coding issues.
ok..running into a wall of inexperience. I need some help and fast (obviously) the drive isnt responding as it should (i'm sure because of the programming and how do you incorprate examp;es into your code?...Rookie Rookie Rookie..Any help would be awesome from you guys out there.
There are a couple mecanum examples in the LabVIEW Example Finder (Help>>Find Examples...). I would suggest starting out with Mecanum Steering.VI. This is going to allow you to get a feel for how mecanum steering actually works. After that you will use the Teleop VI (from the 2015 FRC Project), which is a great starting point for controlling motors. To control mecanum motors, all you need to do, on a basic level, is switch out the Tank Drive in the Teleop VI for the Holonomic Drive VI. Hopefully this should help you get started.
