Microprocessor-controlled servo device for carrying and moving camera

A servo device for controlling and driving a camera, comprising:

• a microprocessor processing control circuit for generating a first and second control pulse signal;
• a first potentiometer for providing a first reference signal;
• a second potentiometer for providing a second reference signal;
• a first deceleration DC motor for rotating the camera in a horizontal direction;
• a second deceleration DC motor for rotating the camera in a vertical direction;
• a first gear set for connecting the first deceleration DC motor to the first potentiometer;
• whereby the first gear set allows the deceleration DC motor to rotate more than 360 degrees;
• a second gear set for connecting the second deceleration DC motor to the second potentiometer;
• a first comparator for comparing the first control pulse signal and the first reference signal and outputting a first drive signal;
• whereby, if the first control pulse signal is larger than the first reference signal, the first drive signal will cause the first deceleration DC motor to rotate in a forward direction;
• whereby, if the first control pulse signal is smaller than the first reference signal, the first drive signal will cause the first deceleration DC motor to rotate in a backward direction;
• and
• whereby, if the first control pulse signal is equal to the first reference signal, the first drive signal will cause the first deceleration DC motor to stop;
• a second comparator for comparing the second control pulse signal and the second reference signal and outputting a second drive signal;
• whereby, if the second control pulse signal is larger than the second reference signal, the second drive signal will cause the second deceleration DC motor to rotate in a forward direction;
• whereby, if the second control pulse signal is smaller than the second reference signal, the second drive signal will cause the second deceleration DC motor to rotate in a backward direction;
• and
• whereby, if the second control pulse signal is equal to the second reference signal, the second drive signal will cause the second deceleration DC motor to stop.

• and
• whereby rotation of the first deceleration DC motor will cause the camera to rotate in a horizontal direction and rotation of the second deceleration DC motor will cause the camera to rotate in a vertical direction.
