Servo Matching - 08/18/2001

MVC-250F.JPG (55367 bytes) This is the "protractor" I used to measure the center point of each servo (or the distance right and left of center) as well as the sweep.  The pointer is 1/8x1/4" spruce and is attached to the Nelson servo arm with 4-40 socket head cap screws.

Servo Matching This is the Excel spreadsheet that I used to capture the results.  The averages are simply to see if the servos are close in terms of the distance between left and right center (16 degrees) and total sweep (120 degrees).  Click on the link at left to download.
