Abstract: Embodiments of the present disclosure relate to an apparatus and method for adjusting an attitude of a target object. An attitude adjusting apparatus includes: a driving device that includes a motor that generates a driving force; and a controller that adjusts an attitude of a target object by referring to a rotation angle of the motor. The driving device includes: a sensing module that generates a magnetic field and senses a change of the magnetic field; and a target that rotates by the driving force of the motor, the target including one blade that changes the magnetic field generated by the sensing module, and the controller determines the rotation angle of the motor by referring to the change of the at least one magnetic field sensed after a preset waiting time has elapsed from a point in time at which rotation of the motor is terminated.
