My team wanted a non-linear approach to acceleration that would add a deadzone so we could control our driving.
I went off and played with the joystickget.vi located in the teleop.vi and came up with this:
That 'x**3' is x^3 which looks like this on a graph:
The
blue represents the normal linear acceleration in which there is no dead zone and what you press is what you get. The
red is the x**3 which adds a deadzone that, in my team's case, helped people driving not crash into walls right away. The functions are wired into the axis (x and y for driving). I don't know if that's really what you are asking for but I hope this helps.
EDIT: I also noticed you are from MN; What city?
