    Abstract: A robot cleaner is disclosed. The robot cleaner comprises: a wireless communication module comprising wireless communication circuitry; a UWB communication module comprising UWB communication circuitry; and at least one processor, comprising processing circuitry, individually and/or collectively, configured to: identify whether at least one electronic device capable of UWB communication and at least one electronic device capable of wireless communication are present in a space where the robot cleaner is located, and based on the presence of a first electronic device capable of UWB communication and a second electronic device capable of wireless communication being identified, identify a first distance between the first electronic device and the robot cleaner using the UWB communication module, identify a second distance between the second electronic device and the robot cleaner using the wireless communication module, identify a third distance between a charging station, located in the space and capable of UWB communication, and the robot cleaner using the UWB communication module, and identify the location of the robot cleaner based on the first distance, the second distance, the third distance, the location of the first electronic device, the location of the second electronic device, and the location of the charging station, wherein wireless communication includes a communication scheme different from UWB communication.

    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.
