+1. It will wait you press D7 to start.
+2. First it would auto detect the SERVO_LEFT maximum angle and SERVO_RIGHT minimum angle
+3. Second it would collect hundreads of point for each servo to caculate the Linear regression 
+4. Third it will wait you to move uArm to correct position to calibrate the SERVO_ROT, You could refer this picture.
