Summarize this article for a 10 year old
A servomotor (or servo motor or simply servo)[1] is a rotary or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system.[1][2] It constitutes part of a servomechanism, and consists of a suitable motor coupled to a sensor for position feedback and a controller (often a dedicated module designed specifically for servomotors).

Servomotors are not a specific class of motor, although the term servomotor is often used to refer to a motor suitable for use in a closed-loop control system. Servomotors are used in applications such as robotics, CNC machinery, and automated manufacturing.
