Robot for projecting image and method for projecting image thereof

A method for projecting an image by a robot including a projector, the method comprising:

• identifying a plurality of candidate projection areas based on first information obtained by sensing surroundings of a user via a sensor;
• identifying a priority order of the plurality of candidate projection areas;
• projecting a first image, via the projector, at an area comprising the plurality of candidate projection areas, based on a plurality of positions of the plurality of candidate projection areas and the priority order;
• displaying second information on the priority order at the plurality of candidate projection areas;
• identifying a candidate projection area selected based on a user input from among the plurality of candidate projection areas as a projection area;
• and
• projecting image content at the projection area via the projector.

A non-transitory computer-readable recording medium having instructions recorded thereon, that, when executed by one or more processors of a robot including a projector, cause the robot to:

• identify a plurality of candidate projection areas based on first information obtained by sensing surroundings of a user via a sensor;
• identify a priority order of the plurality of candidate projection areas;
• control the projector to:
• project a first image at an area comprising the plurality of candidate projection areas, based on a plurality of positions of the plurality of candidate projection areas and the priority order;
• and
• display second information on the priority order at the plurality of candidate projection areas;
• identify a candidate projection area selected based on a user input from among the plurality of candidate projection areas as a projection area;
• and
• project image content at the projection area via the projector.
