How do you want to use the throttle (axis 3)?

All the way down is 1
midway is 0
all the way up is -1

So for instance, if you just want it to limit the top speed of the robot, then you might

  • invert it (multiply by -1) to make down slow and up fast.
  • Normalize the value to between 0 and 1 (add 1 and divide by 2)
  • Use the resulting value (multipy the throttle value by the value coming from the y axis in a tank drive for instance).
