Abstract: A robot includes a 2D camera, a 1D distance sensor, a driving module configured to move the robot, and at least one processor. The at least one processor is configured to: obtain a 2D image by controlling the 2D camera; calculate relative depths of actual regions indicated by pixels in the 2D image, based on the obtained 2D image; obtain a reference distance to a point to which a laser output from the 1D distance sensor is irradiated; determine a distance from the robot to the object in the 2D image based on the obtained reference distance and a relative depth of a reference point corresponding to the point to which the laser is irradiated among the pixels in the 2D image; and travel based on the determined distance to the object.

Abstract: Provided are a robot driven by controlling a time of flight (TOF) light detection and ranging (LiDAR) sensor, and a driving method thereof. The robot outputs laser pulse signals of the TOF LiDAR sensor by switching a laser pulse signal of a short-range pulse energy and a laser pulse signal of a remote pulse energy, while the TOF LiDAR sensor rotates, corrects information about a distance between the robot and peripheral objects of the robot, based on reflection signals of the laser pulse signals, the reflection signals being received from the peripheral objects of the robot, and controls the driving module to move the robot based on the corrected information about the distance.

Abstract: A method and device for predicting errors in a computing system are disclosed. The error prediction method includes: receiving log data generated by the computing system during operation of the computing system; tokenizing the log data into tokens; inputting the tokens to a discriminator model which generates scores of the respective tokens, each score corresponding to a probability that the corresponding token is an anomaly token; determining an anomaly score based on the scores; and determining a likelihood of future occurrence of an error in the computing system based on the anomaly score.

Abstract: A controlling method of a cleaning robot is provided. The controlling method includes obtaining lidar data while a lidar sensor rotates multiple times, calculating a reference value which is the average value of distances from a subject according to angles, based on the obtained lidar data, after the reference value is calculated, comparing the obtained lidar data with the reference value, sensing a motion of an object based on a comparison result, and determining that the object is located in a rotation section where the motion has been detected.
