Robot comprising lidar sensor and method controlling robot

An electronic device comprising:

• a first sensor mounted inside a body of the electronic device;
• a second sensor configured to sense a posture of the body;
• an optical device configured to:
• reflect light output from the first sensor by using at least one mirror, and
• output the reflected light to an outside of the electronic device through a transparent region in the electronic device;
• and
• a processor configured to:
• obtain information on the posture of the body through the second sensor,
• obtain information on a tilting angle of the at least one mirror based on the obtained information on the posture of the body and based on a refractive index of the transparent region, and
• control the at least one mirror based on the obtained information on the tilting angle.
