👉 Servo is a device that can be controlled by electric current. It consists of a small, rigid rod with two or more blades attached to it, and a spring or other force-acting mechanism. When the electric current flows through the motor, it causes the blades to rotate, moving the servo's position in one direction or another. This allows for precise control over the servos' movement, from relatively simple movements like turning a wheel, to more complex tasks like controlling a robotic arm.
