Servo systems application

Servo motor has lots of application in our life.It can be used lots industrial ,and medical applications .In this video we tried to explain that how to control the direction of servo motor by using potentiometer so that we can rotate the shaft of the motor by the amount of rotation which we want .Normally,servo motors have some constraint in rotation amount .Some of them may rotate 180 degrees the other may rotate 360 .As an example ,we in controlling cars vehicles direction .smoothly we can replace the classical systems that they are follow by attaching a four bar mechanism to front wheels to be connected with one degrees of freedom servo motor attached to one joint ,and the potentiometer will be attached to the wheel driver where we can rotate the system lightly ,with small energy and high efficiency.In addition to that ,servo motor can be used in surveillance cameras that we are seeing everyday,also in automatic gate that placed in front of our houses.
