What is servo?
A servo is a device that is used to control the position of a mechanism or device. It consists of a motor, a gear system, and a feedback sensor. The motor is responsible for rotating the shaft of the servo, and the gear system helps to reduce the torque and increase the precision of the movement. The feedback sensor is used to measure the position of the shaft and compare it to a desired position.
When a servo receives a command signal, it compares the desired position to the current position of the shaft. If the two positions are different, the servo adjusts the shaft's position until it matches the desired position. This process is known as servomechanism.
Servos are commonly used in a variety of applications where precise control of a mechanism or device is required, such as in robotics, factory automation, and aircraft control systems. They are available in a range of sizes and power levels to suit different applications.
