1. A crosswalk walking assistance system comprising:
- guide rails along boundary lines of a crosswalk, the boundary lines at both sides of a width of the crosswalk, the boundary lines crossing a road on which vehicles run;
robots configured to move along the guide rails; and
a controller electrically connected to the robots through the guide rails, the controller configured to transmit information indicating that a traffic signal is changed from a stop signal to a walk signal to the robots so that,(i) the robots are configured to determine whether or not an obstacle is present on movement paths of the robots before crossing the crosswalk,(ii) if it is determined that the obstacle is present, the robots determine whether or not the obstacle is a person,(iii) if it is determined that the obstacle is a person, the robots output a voice signal recommending that the person moves to an inside of the crosswalk,(iv) if it is determined that the obstacle is not a person, the robots output an alert signal, and(v) if it is determined that there is no obstacle, the robots output a voice signal indicating that the traffic signal is changed to a walk signal.

Abstract
A crosswalk walking assistance system to assist a pedestrian by moving a movable robot along with the pedestrian along a boundary of a crosswalk when the pedestrian crosses at the crosswalk, and a method of controlling the same. The crosswalk walking assistance system includes guide rails formed along boundary lines of a crosswalk, robots moving along the guide rails, and a controller connected to the guide rails.

13. A crosswalk walking assistance system comprising:
-
guide lines along boundary lines of a crosswalk, the boundary lines at both sides of a width of the crosswalk, the boundary lines crossing a road on which vehicles run; robots configured to move along the guide lines; and controllers provided on ends of the guide lines and electrically connected to the robots through the guide lines, the controller configured to transmit information indicating that a traffic signal is changed from a stop signal to al walk signal to the robots so that, (i) the robots are configured to determine whether or not an obstacle is present on movement path of the robots before crossing the crosswalk, (ii) if it is determined that the obstacle is present, the robots determine whether or not the obstacle is a person, (iii) if it is determined that the obstacle is a person, the robots output a voice signal recommending that the person moves to the inside of the crosswalk, (iv) if it is determined that the obstacle is not a person, the robots output an alert signal, and (v) if it is determined that there is no obstacle, the robots output a voice signal indicating that the traffic signal is changed to a walk signal. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method comprising:
-
sensing, by a robot, whether or not an obstacle is present on a movement path of the robot when information indicating that a signal of a traffic light is changed to a walk signal is received by the robot from a controller; moving the robot along a guide rail or a guide line while outputting a voice signal indicating that the signal is changed to the walk signal, when it is sensed by the robot that an obstacle is not present, the guide rail or the guide line along a boundary line, the boundary line at a side of a width of the crosswalk and crossing a road on which vehicles run; determining, by the robot, whether or not the obstacle is a person when it is sensed by the robot that an obstacle is present, and outputting a voice signal by the robot recommending that the person moves to an inside of a crosswalk; outputting a voice signal recommending that the person moves to an inside of the crosswalk when it is determined that the obstacle is a person; generating an alert signal by the robot to remove the obstacle when it is determined that the obstacle is not a person; moving the robot along the guide rail or the guide line to thereby move to the other side of the crosswalk while outputting a voice signal indicating that the signal has changed to the walk signal when the obstacle is removed; and outputting an indication by the robot that the signal has changed to a stop signal when movement of the robot to the other side of the crosswalk is completed, and then waiting by the robot until the signal is changed to the walk signal. - View Dependent Claims (20, 21, 22, 23, 24, 25)

26. A system comprising:
-
a guide rail along a boundary line of a crosswalk, the boundary lines at both sides of a width of the crosswalk, and the boundary lines crossing a road on which vehicles run; a robot configured to move along the guide rail; and a controller connected to the guide rail, the controller configured to, control the robot by providing power and signals through the guide rail, transmit information indicating that a traffic signal is changed from a stop signal to a walk signal to the robots so that, the robot determines whether or not an obstacle is present on a movement path of the robot before crossing the crosswalk, and if it is determined that the obstacle is present, the robot determines whether or not the obstacle is a person, and output an alert signal if it is determined that the obstacle is not a person, a first voice signal recommending that a pedestrian moves to an inside of the crosswalk if it is determined that the obstacle is a person, and a second voice signal indicating that the traffic signal is changed to a walk signal if it is determined that there is no obstacle.
