Servo

A servo, short for servomechanism, is a device that can control the position or speed of an object with precision. It uses feedback to adjust its movements, ensuring accuracy. Commonly found in robotics, remote-controlled models, and automation systems, a servo typically consists of a motor, a sensor, and a controller. The controller sends commands to the motor based on the sensor's input, allowing the system to maintain or reach a desired position. This technology is essential for applications needing exact movements, such as steering in RC cars or positioning in robotic arms.
