Servo
Description
Servo is a set of automatic control system composed of DC motors, reduction gear set,
sensors and control circuits. The output shaft can be rotated to a certain angle by sending
signals. The servo can only rotate in a certain range, for example, 180°. It cannot rotate any
circles like the DC motor. The servo enables you to easily rotate an object in a certain angle,
so it is widely used in model planes and robot joints.
In this kit, twelve 9 micro servos are used to drive the joints of the robot.
