1. An attitude adjustment apparatus comprising:
a base part;
a first rotating part rotatably coupled to the base part;
a second rotating part configured to be fixedly coupled to a target object and rotatably coupled to the first rotating part; and
a controller configured to adjust an attitude of the target object by controlling rotation of the first rotating part and the second rotating part,
wherein the base part comprises:
a first motor configured to generate a first driving force;
a first sensing portion comprising a sensor, the first sensing portion configured to generate a first magnetic field and detect changes in the first magnetic field; and
a first target that is configured to be rotated by the first driving force of the first motor, the first target comprising a plurality of first blades that are configured to change the first magnetic field generated by the first sensing portion,
wherein the first rotating part comprises:
a second motor configured to generate a second driving force;
a second sensing portion comprising a sensor, the second sensing portion configured to generate a second magnetic field and detect changes in the second magnetic field; and
a second target that is configured to be rotated by the second driving force of the second motor, the second target comprising a plurality of second blades that are configured to change the second magnetic field generated by the second sensing portion, and
wherein the controller is further configured to:
determine a rotation angle of the first motor based on sensing results from the first sensing portion and identification information of a first reference blade, from among the plurality of first blades, that is causing the changes in the first magnetic field; and
determine a rotation angle of the second motor based on sensing results from the second sensing portion and identification information of a second reference blade, from among the plurality of second blades, that is causing the changes in the second magnetic field.
