Thus we can calibrate as follows:

① Decrease the upper-right servo’s angle

Change 95 degrees to 90 (array_cal[0]: is the upper-right servo’s rotation angle);

② Increase the upper-left servo’s angle

Change 115 degrees to 120 (array_cal[2]: is the upper-left servo’s rotation angle);

③ Decrease the lower-right servo’s angle

Change 100 degrees to 90 (array_cal[1]: is the lower-right servo’s rotation angle);

④ Increase the lower-left servo’s angle

Change 95 degrees to 100 (array_cal[3]: is the lower-left servo’s rotation angle);

i.e.: In line 15, change code to array_cal[4] = {90, 90, 120, 100}; Then click Upload.

The edge of upper-left plate and upper plate are parallel with each other, but upper-right is

not parallel to the upper one, the deviation angles of lower-left and lower-right servos are

decreased.
