Guidance robot and method for navigation service using the same

A facility guide method of a robot for guiding a facility user, comprising:

• capturing, using a camera mounted to a body of the robot, an image or a video of users in a facility;
• determining facility users who have visited the facility based on a history of visits to the facility based on facility use information and biometric information of the facility users received via a network;
• determining whether to provide a guide information on the facility to a first user among the facility users who have visited the facility based on at least one of a number of pupil movements of the first user or a number of head movements of the first user extracted from the captured image or the captured video without an explicit request by the first user for the guide information on the facility;
• moving the body of the robot to a location adjacent to the first user;
• and
• providing the guide information in a form of at least one of a voice from a speaker or an image on a display based on the determining to provide the guide information to the first user,
• wherein the facility use information is generated when the first user uses the facility, wherein the facility use information includes at least one of a number of visits to the facility by the first user or historical information of visiting a space in the facility by the first user.

A non-transitory memory storing one or more programs, which, when executed by one or more processors of a robot, cause the robot to perform a facility guide method for guiding a facility user, the one or more processors comprising instructions for:

• capturing, using a camera mounted to a body of the robot, an image or a video of users in a facility;
• determining facility users who have visited the facility based on a history of visits to the facility based on facility use information and biometric information of the facility users received via a network;
• determining whether to provide a guide information on the facility to a first user among the facility users who have visited the facility based on at least one of a number of pupil movements of the first user or a number of head movements of the first user extracted from the captured image or the captured video without an explicit request by the first user for the guide information on the facility;
• moving the body of the robot to a location adjacent to the first user;
• and
• providing the guide information in a form of at least one of a voice from a speaker or an image on a display based on the determining to provide the guide information to the first user,
• wherein the facility use information is generated when the first user uses the facility, wherein the facility use information includes at least one of a number of visits to the facility by the first user or historical information of visiting a space in the facility by the first user.
