is a precise actuator—either rotary or linear—designed for the exact control of angular or linear position, velocity, and acceleration. Unlike standard motors that rotate continuously when powered, a servo operates within a closed-loop system
History and development Servo-control concepts originated from feedback control theory developed in the late 19th and early 20th centuries. Early servomechanisms were used in naval gun stabilization and radio-controlled systems. As electric motors, sensors, and electronic control systems improved through the 20th century, compact and more capable servo motors emerged. The growth of digital electronics, microcontrollers, and affordable sensors since the 1980s enabled precise, programmable servos widely used in robotics, CNC machines, and consumer products.

Often measured in seconds per 60 degrees (e.g., 0.15s/60°) rather than RPM, especially for standard hobby servos.
