Abstract
The present invention is the invention for providing a guidance service by using a robot. For example, the robot may provide the guidance service in an airport. The robot may receive a destination, acquire a movement path from a current position to the destination, and transmit the movement path to the mobile terminal. The mobile terminal may receive the movement path from the robot and display a guidance path representing a movement path and a user path representing a position movement of the mobile terminal and overlapping the guidance path.
Claims12
A system comprising:
- a robot configured to receive in input identifying a destination, and determine a movement path from a starting position to the destination;
- and
- a mobile terminal configured to receive information associated with the movement path from the robot, and display a map based on the movement path,
- wherein the map includes a guidance path representing the movement path and a user path representing a movement of the mobile terminal along the guidance path,
- wherein the mobile terminal further configured to:
- receive a location signal from each of a plurality of robots, each of the location signals includes information identifying a current position of one of the robots that transmitted the location signal when the location signal is transmitted and time information about a time when the location signal is transmitted,
- identify respective times when the location signals are received,
- determine respective time differences between the times when the locations signals are transmitted and the times when the location signals are received,
- calculate distances to the robots based multiplying the time differences and a velocity of the location signals, and
- recognize a current position of the mobile terminal based on the current positions of the robots and the distances to the robots.

A mobile terminal comprising:
- a wireless communication interface configured to receive information related to a movement path from a robot;
- a display configured to present a map based on of the movement path;
- and
- a controller configured to manage the display to present, on the map, a guidance path representing the movement path and a user path representing a movement of the mobile terminal along the guidance path,
- wherein the wireless communication interface receives a location signal from each of a plurality of robots, each of the location signals includes information identifying a current position of one of the robots that transmitted the location signal when the location signal is transmitted and time information about a time when the location signal is transmitted, and
- wherein the controller is further configured to:
- identify respective times when the location signals are received,
- determine respective time differences between the times when the locations signals are transmitted and the times when the location signals are received,
- calculate distances to the robots based multiplying the time differences and a velocity of the location signals, and
- recognize a current position of the mobile terminal based on the current positions of the robots and the distances to the robots.

An operating method of a mobile terminal, the operating method comprising:
- receiving information associated with a movement path from a robot;
- identifying a current position of the mobile terminal;
- determining a movement of the mobile terminal based on the current position of the mobile terminal;
- and
- displaying a guidance path representing the movement path and a user path representing the movement of the mobile terminal and overlapping the guidance path,
- wherein the operating method further comprises:
- receiving a location signal from each of a plurality of robots, each of the location signals includes information identifying a current position of one of the robots that transmitted the location signal when the location signal is transmitted and time information about a time when the location signal is transmitted, and
- wherein identifying the current position of the mobile terminal comprises:
- identifying respective times when the location signals are received;
- determining respective time differences between the times when the locations signals are transmitted and the times when the location signals are received;
- calculating distances to the robots based multiplying the time differences and a velocity of the location signals;
- and
- recognizing the current position of the mobile terminal based on the current positions of the robots and the distances to the robots.
