At RobotShop, we carry a wide variety of servo motors but it only becomes apparent once all the major kinds are put side by side.
Family of Servo Motors
From left to right, the picture above shows the Dagu Micro, the HS-85MG (Mighty Micro), the HS-422 (one of the most popular servos), the HS-785HB Winch, the Servocity Heavy Duty Pan System, and the ridiculously powerful Torxis i00600.
Servos are evolving, especially lately when they started being used in robotic projects that go far beyond the more traditional R/C.
A notable absent in this picture is the diminutive HS-35D Nano which is smaller than even the smallest one in the picture.

Not only are servos growing but the complexity behind servo repair is too. But thanks for the article, it was very interesting.
Servo Actuators
Very Interesting technology of servo motors family from gaint to tiny.
