Robot cleaner for recognizing stuck situation through artificial intelligence and method of operating the same

A robot cleaner for recognizing a stuck situation through artificial intelligence, the robot cleaner comprising:

• a driving motor to drive the robot cleaner;
• a sensor configured to acquire three-dimensional (3D) image data and a bumper event;
• a memory configured to store a stuck situation recognition model for inferring the stuck situation of the robot cleaner;
• and
• a processor configured to:
• convert the 3D image data and the bumper event into surrounding map image data,
• inter the stuck situation of the robot cleaner from the surrounding map image data using the stuck situation recognition model,
• control the driving motor according to an inference result,
• measure a current traveling angle of the robot cleaner at a time point when the stuck situation is detected, and
• determine a rotation angle of the robot cleaner for escaping the stuck situation based on the measured current traveling angle and a plurality of traveling angles measured at a plurality of time points before the stuck situation is detected.
