US 12,422,851 B2 · Robot operable to disembark from escalator and method of controlling same

Abstract

Provided is a robot and method of controlling same, where the robot includes: a sensor; a driver; a memory storing an instruction; and a processor configured to execute the instruction to: identify, through the sensor, a height difference between a first stair and a second stair of an escalator, identify whether the robot is adjacent to a disembarkment area of the escalator based on the identified height difference, based on identifying that the robot is adjacent to the disembarkment area, identify, through the sensor, whether an object is located within a first distance of the robot in a movement direction of the escalator, and based on identifying the object located within the first distance of the robot in the movement direction of the escalator, control the driver to cause the robot to move on the escalator in a direction opposite to the movement direction of the escalator.

Dependent claims

A robot comprising:

at least one sensor;
a driver;
at least one memory storing at least one instruction;
and
at least one processor configured to execute the at least one instruction to:
identify, through the at least one sensor, a height difference between a first stair and a second stair of an escalator,
identify whether the robot is adjacent to a disembarkment area of the escalator based on the identified height difference,
based on identifying that the robot is adjacent to the disembarkment area, identify, through the at least one sensor, whether an object is located within a first distance of the robot in a movement direction of the escalator, and
based on identifying the object located within the first distance of the robot in the movement direction of the escalator, control the driver to cause the robot to move on the escalator in a direction opposite to the movement direction of the escalator.

6 more elements

A method of controlling a robot, the method comprising:

identifying, through at least one sensor of the robot, a height difference between a first stair and a second stair of an escalator;
identifying whether the robot is adjacent to a disembarkment area of the escalator based on the identified height difference;
based on identifying that the robot is adjacent to the disembarkment area, identifying whether an object is located within a first distance of the robot in a movement direction of the escalator;
and
based on identifying the object located within the first distance of the robot in the movement direction of the escalator, controlling a driver of the robot to cause the robot to move on the escalator in a direction opposite to the movement direction of the escalator.

2 more elements

A non-transitory computer readable medium having instructions stored therein, which when executed by at least one processor cause the at least one processor to execute a method of controlling a robot, the method comprising:

identifying, through at least one sensor of the robot, a height difference between a first stair and a second stair of an escalator;
identifying whether the robot is adjacent to a disembarkment area of the escalator based on the identified height difference;
based on identifying that the robot is adjacent to the disembarkment area, identifying whether an object is located within a first distance of the robot in a movement direction of the escalator;
and
based on identifying the object located within the first distance of the robot in the movement direction of the escalator, controlling a driver of the robot to cause the robot to move on the escalator in a direction opposite to the movement direction of the escalator.
