Need Help With Robot Jumpyness

Hey guys!

(First post on CD, yay! :smiley: )

I need some help making our robot less sensitive to the joystick, or some relative acceleration. I am using the basic tutorial code and an arcade drive.

RobotDrive chassis = new RobotDrive(1,2);
    Joystick main = new Joystick(1);
public void operatorControl() {
        while(isOperatorControl() && isEnabled()) {

I’ve updated your code with a simple scalar function.

I just used excel and plotted a 2 order polynomial trendline.

Here are the scalars I used:

for less than 0:
in : out
-1 -1
-0.75 -0.5
-0.5 -0.25
-0.25 -0.12

0 0

for greater than 0:
in : out
0.25 0.12
0.5 0.25
0.75 0.5
1 1

If its still too fast I would start by reducing the starting scalar.

Thanks, that worked! A note to anyone else who wants to use this, 0.6 is too low of a scale factor for the 2 motor long AM14u chassis, we use 0.9. Also, there was a small error in the code above, one place where it says Y is supposed to be X. I am sure you can see that easily. Thanks again everyone. :smiley:
