Simple project, willing to pay $$$ for basic coding - 4 Servos + Ping)))

-The value for speed is directly proportional to the distance in inches from the sensor.

So, in loop(), change:

        servoSpeed[roll]= 1;
        servoSpeed[pitch]= 2; 
        servoSpeed[yaw]= 2;
        servoSpeed[Boo]=  1;

to:

        servoSpeed[roll]= inches/10;
        servoSpeed[pitch]= 2 * inches/10; 
        servoSpeed[yaw]= 2 * inches/10;
        servoSpeed[Boo]=  inches/10;
