Robot capable of detecting dangerous situation using artificial intelligence and method of operating the same

A robot for detecting danger using artificial intelligence, the robot comprising:

• a memory configured to store a danger recognition model comprising a voice recognition model or an image recognition model each comprising an artificial neural network trained using a supervised deep learning algorithm;
• an input unit configured to acquire audio or image data;
• and
• a processor configured to:
• input the acquired audio or image data to the danger recognition model;
• and
• output a notification indicating a dangerous situation corresponding to an emergency or hazard based on an output of the danger recognition model given the acquired audio or image data as input,
• wherein the processor is further configured to:
• calculate a density value of people in each of a plurality of regions to determine a movement route of the robot, wherein the density value of a region is based on a number of recognized persons based on the image data, and
• increase a density value of a particular region of the plurality of regions based on detecting the dangerous situation in the particular region such that a priority of the particular region is increased to determine the movement route of the robot.
