Abstract
A robot for moving in an administrator mode, can include a positioning sensor configured to sense a transmitter for calculating a position of the transmitter; an obstacle sensor configured to sense an obstacle around the robot; a driver configured to move the robot; and a controller configured to in response to receiving a signal from the transmitter, align the robot toward the position of a transmitter, move the robot toward the transmitter while avoiding one or more obstacles sensed by the obstacle sensor, and in response to no longer receiving the signal from the transmitter or a distance between the transmitter and the robot being equal to or less than a preset distance, stop the robot.
Claims16
A robot for moving in an administrator mode, the robot comprising:
- a positioning sensor configured to sense an administrator transmitter and calculate a position of the administrator transmitter;
- an obstacle sensor configured to sense an obstacle around the robot;
- a driver configured to move the robot;
- and
- a controller configured to:
- in response to receiving a signal from the administrator transmitter, align the robot toward the position of the administrator transmitter,
- move the robot toward the administrator transmitter while avoiding one or more obstacles sensed by the obstacle sensor, and
- in response to no longer receiving the signal from the administrator transmitter or a distance between the administrator transmitter and the robot being equal to or less than a preset distance, stop the robot,
- wherein the administrator mode is a mode in which two or more robots move while following the administrator transmitter,
- wherein the robot enters in the administrator mode when the robot receives an external control signal or when the robot completes a pre-programmed operation, and
- wherein the controller is further configured to:
- control the robot to face the administrator transmitter by rotating the robot based on an absolute value of a centerline angle between a centerline of the robot and the position of the administrator transmitter,
- control the robot to move straight toward the administrator transmitter if the absolute value of the centerline angle is within a preset reference angle, and
- switch a mode of the robot into the administrator mode and control the robot to move while following the administrator transmitter based on the signal received from the administrator transmitter when a second signal is not detected from a user carrying transmitter instructing a user following mode, or
- switch to the mode of the robot into the administrator mode when the user carrying transmitter is disposed inside of the robot.

A method for moving a robot in an administrator mode, the method comprising:
- sensing an administrator transmitter and calculating a position of the administrator transmitter by a positioning sensor of the robot;
- aligning, by a controller of the robot, the robot toward the administrator transmitter based on a signal received from the administrator transmitter;
- sensing, by an obstacle sensor of the robot, an obstacle around the robot;
- moving, by the controller, the robot toward the administrator transmitter while avoiding the obstacle sensed by the obstacle sensor;
- and
- in response to no longer receiving the signal from the administrator transmitter or a distance between the administrator transmitter and the robot being equal to or less than a preset distance, stopping the robot,
- wherein the administrator mode is a mode in which two or more robots move while following the administrator transmitter,
- wherein the robot enters in the administrator mode when the robot receives an external control signal or when the robot completes a pre-programmed operation, and
- wherein the method further comprises:
- controlling the robot to face the administrator transmitter by rotating the robot based on an absolute value of a centerline angle between a centerline of the robot and the position of the administrator transmitter;
- controlling the robot to move straight toward the administrator transmitter if the absolute value of the centerline angle is within a preset reference angle;
- and
- switching, by the controller, a mode of the robot into the administrator mode and controlling the robot to move while following the administrator transmitter based on the signal received from the administrator transmitter when a second signal is not detected from a user carrying transmitter instructing a user following mode, or
- switching, by the controller, the mode of the robot into the administrator mode when the user carrying transmitter is disposed inside of the robot.
