Abstract
A robot includes: a travel unit configured to move the robot; a light detection and ranging (LiDAR) sensor; and at least one processor configured to: obtain first distance data between the robot and objects around the robot by using the LiDAR sensor, obtain line data corresponding to an object having a line shape based on the first distance data, control the travel based on the line data to move the robot, track the line data based on second distance data obtained by the LiDAR sensor while the robot moves, and identify a curvature value of the tracked line data, and identify whether the LiDAR sensor is defective based on a change in the curvature value.

A robot comprising:
- a travel unit configured to move the robot;
- a light detection and ranging (LiDAR) sensor;
- and
- at least one processor configured to:
- obtain first distance data between the robot and objects around the robot by using the LiDAR sensor,
- obtain line data corresponding to an object having a line shape based on the first distance data,
- control the travel based on the line data to move the robot,
- track the line data based on second distance data obtained by the LiDAR sensor while the robot moves, and identify a curvature value of the tracked line data, and
- identify whether the LiDAR sensor is defective based on a change in the curvature value.
A method for controlling a robot, the method comprising:
- obtaining first distance data between the robot and objects around the robot by using a light detection and ranging (LiDAR) sensor;
- obtaining line data corresponding to an object having a line shape based on the first distance data;
- moving the robot based on the line data;
- tracking the line data based on second distance data obtained by the LiDAR sensor while the robot moves, and identifying a curvature value of the tracked line data;
- and
- identifying whether the LiDAR sensor is defective based on a change in the curvature value.
A non-transitory computer readable medium storing instructions that when executed by at least one processor directs the at least one processor to perform a method for controlling a robot, the control method including:
- obtaining first distance data between the robot and objects around the robot by using a light detection and ranging (LiDAR) sensor;
- obtaining line data corresponding to an object having a line shape based on the first distance data;
- moving the robot based on the line data;
- tracking the line data based on second distance data obtained by the LiDAR sensor while the robot moves, and identifying a curvature value of the tracked line data;
- and
- identifying whether the LiDAR sensor is defective based on a change in the curvature value.
