Re: Holonomic Control System

We used mecanum last year which is pretty much the same from a control point of view. We tried both a single 3-axis joystick and 2 dual axis. We ended up going with 2 dual axis, using one for position control, and one for rotation because that was what our driver prefered, I personally liked the 3 axis better. So I would recommend trying both and just seeing what feels more natural, if your code is writen well, it should be trivial to change.

Also, I would STRONGLY recommend that you look into using a gyro to compensate for robot rotation. Basicly, when you push the movement stick forward, the robot knows how it is oriented and will always move away from you. Likewise, when you move the stick left, it will always go left relative to the control station. This takes just a few minutes to get used to, and is extremely natural after that. If you go with this it is very important to have a button that turns it off also because sometimes the gyro gets messed up.
