Robot traveling in specific space and control method thereof

A method of controlling a robot, the method comprising:

• identifying whether a viewing zone of at least one sensor of the robot will be within a predetermined distance from a privacy protection zone included in a travel space while the robot travels along a travel path in the travel space;
• based on identifying that the viewing zone of the at least one sensor will be within the predetermined distance, determining whether the viewing zone of the at least one sensor will overlap with the privacy protection zone based on the travel path;
• and
• based on determining that the viewing zone of the at least one sensor will overlap with the privacy protection zone, changing a heading direction of the robot from a first heading direction of the robot to a second heading direction of the robot to prevent the viewing zone of the at least one sensor from overlapping with the privacy protection zone,
• wherein the changing the heading direction of the robot comprises:
• based on identifying that the viewing zone of the at least one sensor is within the predetermined distance, identifying an azimuth of the privacy protection zone based on the heading direction of the robot while the robot travels;
• and
• changing the heading direction of the robot to cause the azimuth of the privacy protection zone to be greater than or equal to a viewing angle of the at least one sensor.

A non-transitory computer-readable medium storing instructions, which are executable by at least one processor cause the at least one processor to execute a method of controlling a robot, the method comprising:

• identifying whether a viewing zone of at least one sensor of the robot will be within a predetermined distance from a privacy protection zone included in a travel space while the robot travels along a travel path in the travel space;
• based on identifying that the viewing zone of the at least one sensor will be within the predetermined distance, determining whether the viewing zone of the at least one sensor will overlap with the privacy protection zone based on the travel path;
• based on determining that the viewing zone of the at least one sensor will overlap with the privacy protection zone based on the travel path, changing a heading direction of the robot from a first heading direction of the robot to a second heading direction to prevent the viewing zone of the at least one sensor from overlapping with the privacy protection zone;
• identifying an emission angle for emitting light to an area corresponding to the viewing zone of the at least one sensor;
• and
• based on the identified emission angle, emitting the light at the emission angle to the area corresponding to the viewing zone of the at least one sensor for distinguishing the viewing zone of the at least one sensor.
