A servo motor is a rotary actuator that allows for precise control of angular position. Servo motors are 180 degrees rotational motors. This means, that the motor can only rotate half a circle. It is a very precise motor, using degrees as a command you tell the motor how many degrees to spin and in which direction.
When Connecting the Brain, the servo motors will always be positioned in their starting point, which is 0 degrees. If a servo motor is sent to a certain degree (60 for example). The next time we run it, if we try to send it to 60 again, it will not move. The motor is already in that position!
What are they used for?
Robotic applications are some of the most popular ways servor motors are used. For example, a robotic ARM! The mechanism for this requires very precise movement in order to move around and pick up objects correctly. Servo motors allow the arm precision of angular control, unlike when during a DC (direct current) motor.
