Sensor position control apparatus and method

A sensor position control method that controls the position and angle of a sensor used for checking a bolt position alignment, comprising:

• primarily measuring, by a controller, sensor performance of detecting a position of a bolt, wherein the sensor performance is measured based on data stored in a database;
• in response to measuring the sensory performance, calculating, by the controller, a target position of the sensor based on data stored in the database;
• in response to calculating the target position of the sensor, correcting, by the controller, the position of the sensor based the target position of the sensor by operating a position control driving unit and an angle control driving unit;
• and
• in response to correcting the position of the sensor, secondarily measuring, by the controller, the sensor performance;
• comparing, by the controller, the secondarily measured sensor performance to a reference performance previously stored in the database to determine whether the secondarily measured sensor performance corresponds to the reference performance,
• wherein to the controller automatically corrects the position of the sensor.
