Servo

Definition of Servo

A servo is an actuator that receives a small signal from a control device and uses it to exert a large force to accomplish a specific task. Servos are widely used in various electronic devices and machines where precise and accurate control of movement is essential. They are designed to provide accurate and reliable motion control in a range of applications, from robotics and automation to manufacturing and aerospace engineering.

The basic principle behind a servo is that it receives signals from a controller, which tells it how much force to apply and in which direction. The servo then generates the necessary force to move a particular component or part to a specific position. Servos are typically driven by a motor that can adjust the position of a gear or other mechanical part, allowing the servo to control the movement of a mechanism.

One of the key features of servos is their ability to provide precise and continuous control of movement. They are capable of responding to even the smallest changes in input signals, making them ideal for applications that require accurate and repeatable motion. Additionally, servos are known for their high torque output, which allows them to move heavy loads with ease.

In summary, a servo is a highly precise and adaptable actuator that can be used in a wide range of applications. Its ability to receive small signals and translate them into large forces makes it ideal for automation, robotics, and other precision movements.
