The multi-information provider system of a guidance robot may include a user database configured to receive and store user information transmitted from a terminal of a user, a robot database configured to receive pieces of robot information from one or more guidance robots and store the pieces of robot information, a valid robot list generator configured to list pieces of information of guidance robots located within a predetermined effective distance from a location of the user, a service matcher configured to match the user information and each of the pieces of robot information included in a valid robot list, and an outputter configured to output matched service information to the user terminal.",
  "claims": [
    "1. A multi-information provider system of a guidance robot, the multi-information provider system comprising: a user database; a robot database: and a processor configured to: receive user information including a location of a user from a terminal of the user, store the user information to the user database, receive pieces of robot information from guidance robots, and store the pieces of robot information to the robot database, wherein the processor is further configured to: control a valid robot list generator to identify at least one guidance robot boated within a predetermined effective distance from the location of the user among the guidance robots, wherein the valid robot list generator includes a valid robot list updater configured to update the valid robot list by adding, to the valid robot list, service information of the guidance robot that is currently providing a service to another user from among the guidance robots included in the valid robot; control a service matcher to match the user information and the pieces of robot information of the identified at least one guidance robot; control an outputter to output matched service information to the terminal; and generate a valid robot list, and wherein the processor is further configured to: set an effective distance, compare the set effective distance and the distance between the user and the guidance robot, and list information of the guidance robot whose distance to the user is smaller than the effective distance.",
    "2. The multi-information provider system of claim 1, wherein the user terminal includes augmented reality (AR) glasses.",
    "3. The multi-information provider system of claim 1, wherein the guidance robot includes a mobile robot equipped with an autonomous driving function.",
    "4. The multi-information provider system of claim 1, wherein the user information includes a requested service, and preference and non-preference information.",
    "5. The multi-information provider system of claim 1, wherein the robot information includes a location and information on a service currently provided.",
    "6. The multi-information provider system of claim 1, wherein the user database includes a user authenticator configured to determine an access right of the user.",
    "7. The multi-information provider system of claim 1, wherein the user database includes a user information processor configured to process the user information through relevant information corresponding to the user information.",
    "8. The multi-information provider system of claim 7, wherein the user information processor includes a request information processor configured to add corresponding relevant information to the user request information.",
    "9. The multi-information provider system of claim 7, wherein the user information processor includes a preference information processor configured to add corresponding relevant information to user preference information and then remove non-preference information.",
    "10. A multi-information providing method of a guidance robot, the multi-information providing method comprising: receiving user information including a location of a user from a terminal of the user and storing the received user information; receiving pieces of robot information from guidance robots and storing the received pieces of robot information; identifying at least one guidance robot located within a predetermined effective distance from the location of the user among the guidance robots; matching the user information and the pieces of robot information of the identified at least one guidance robot; outputting matched service information to the terminal; wherein the generating the valid robot list comprises: setting an effective distance; comparing the set effective distance and the distance between the user and the guidance robot; and listing information of the guidance robot whose distance to the user is smaller than the effective distance; and updating the valid robot list by adding, to the valid robot list, service information of the guidance robot that is currently providing a service to another user from among the guidance robots included in the valid robot list.",
    "11. The multi-information providing method of claim 10, wherein the user information includes a location, a requested service, and preference and non-preference information.",
    "12. The multi-information providing method of claim 10, wherein the robot information includes a location and information on a service currently provided.",
    "13. The multi-information providing method of claim 10, wherein the guidance robot includes a mobile robot equipped with an autonomous driving function.",
    "14. The multi-information providing method of claim 10, further comprising generating processed information, wherein the generating the processed information comprises processing request information in which relevant information corresponding to user request information is added to the user request information.",
    "15. The multi-information providing method of claim 10, further comprising generating processed information, wherein the generating the processed information comprises processing preference information in which relevant information corresponding to preference information of the user is added to the preference information and non-preference information is removed.",
    "16. The multi-information providing method of claim 10, further comprising matching a service by matching a similar service in which the user information is matched with the pieces of robot information included in an updated valid robot list.",
    "17. The multi-information providing method of claim 16, wherein the matching the service comprises matching a similar service when the user information is not the same as the pieces of robot information included in the updated valid robot list.",
    "18. The multi-information providing method of claim 16, further comprising, when the matching of the similar service is completed, updating the user information by including information generated in each operation."

  "description_excerpt": "The present invention relates to a multi-information provider system of a guidance robot and a method thereof.\n\nGenerally, guidance robots are installed in public places, such as airports, train stations, department stores, theaters, museums, or the like, to provide a variety of information, such as locations and facilities, to users.\n\nRecently, guidance robots utilizing an autonomous driving technology have provided escort services to accompany users to destinations.\n\nIn this regard, prior-art document information is as follows:\n\n1. Korean Laid-Open Patent Publication No. 10-2010-0006975 (published on Jan. 22, 2010)\n\nTitle of the invention: MOVING RECEPTIONIST ROBOT AND SYSTEM THEREOF\n\nThe conventional moving reception robot, however, has the following problems.\n\nAs shown in FIG. 1, the conventional moving reception robot provides information and an escort service according to a user's service request input through a personal terminal.\n\nHowever, the conventional moving reception robot has a drawback in that it cannot provide a service to another user while providing information and performing an escort service for one user.\n\nTo solve this problem, a plurality of moving reception robots may be operated to provide a service to more users, but even in this case, each moving reception robot provides information and performs an escort service for only one user, and thus the operation efficiency of the moving reception robot is lowered.\n\nIn addition, since the moving reception robot is relatively expensive, there is a problem in that economical efficiency is lowered when a plurality of moving reception robots are operated.",
