Robot and method for controlling same

A robot comprising:

• a memory configured to store at least one instruction;
• a camera configured to capture an image of a user;
• and
• at least one processor connected to the memory and the camera and configured to execute the at least one instruction,
• wherein the at least one instruction, when executed by the at least one processor, causes the robot to:
• acquire an image of the user captured by the camera,
• acquire, by analyzing the image of the user, first information regarding a position of the user relative to a position of the robot and a gaze direction of the user relative to the position of the robot,
• acquire, based on an image capturing position of the robot at a point in time when the image is acquired and an image capturing direction of the camera at the point in time when the image is acquired, matching information for matching the first information with a map corresponding to an environment in which the robot is operated,
• acquire, based on the matching information and the first information, second information regarding the position and the gaze direction of the user on the map,
• acquire input data by mapping the second information on a grid map corresponding to the map,
• identify an object corresponding to the gaze direction of the user on the map, from among one or more objects in the environment in which the robot is operated, by inputting the input data to an artificial intelligence model trained to identify an object on the map, and
• based on a command from the user, perform an action or provide an output related to the identified object, and
• wherein the at least one instruction, when executed by the at least one processor, causes the robot to:
• identify coordinates of first cells on the grid map, wherein an angle between the gaze direction of the user and each of the first cells on the grid map is equal to or less than a predetermined angle, and
• generate the input data based on the identified coordinates of the first cells.
