 Here, 500 is the proportional gain and 400 is the derivative gain for the pan servo. Likewise, 600 and 500 are the proportional and derivative gains for the tilt axis. Try reducing the proportional gain by half and see what happens. Many times, increasing the gains results in some erratic behavior, but don't worry -- you won't damage anything.
-With a little tweaking and modifying, this code can become a "chasing" instead of a "tracking" algorithm. That is, instead of calculating servo positions your Arduino can calculate motor speeds. So now your Pixy-Arduino robot creation can chase a ball, toy, etc. The Arduino example **ccc_zumo_chase** does exactly this.  It controls 4 axes: pan, tilt, left and right motors to chase the object it acquires.
