Robot cleaner and control method thereof

A control method of a robot cleaner, the control method comprising:

• storing a map of a space in which the robot cleaner travels;
• operating in an access point (AP) mode of the robot cleaner in which the robot cleaner outputs a wireless signal corresponding to a wireless signal output value of an AP device;
• sequentially moving the robot cleaner to a plurality of measurement locations to output the wireless signal through the AP mode and, with respect to the wireless signal, obtain signal strength information related to a connection strength between the robot cleaner and a plurality of electronic devices disposed in the space, respectively, at the plurality of measurement locations;
• storing the signal strength information in correspondence to the plurality of measurement locations;
• based on the stored signal strength information, identifying a measurement location at which a signal strength of the plurality of electronic devices is a threshold value or more, as a recommended AP location of the AP device, among the plurality of measurement locations;
• and
• providing, to a user terminal device, the signal strength information that was stored in correspondence to the plurality of measurement locations and an AP location recommendation user interface (UI) configured to display, on the user terminal device, the recommended AP location on the map.

A non-transitory computer-readable storage medium storing at least one instruction which, when executed by at least one processor, causes the at least one processor to execute a control method including:

• storing a map of a space in which a robot cleaner travels;
• operating in an access point (AP) mode of the robot cleaner in which the robot cleaner outputs a wireless signal corresponding to a wireless signal output value of an AP device;
• sequentially moving the robot cleaner to a plurality of measurement locations to output the wireless signal through the AP mode and, with respect to the wireless signal, obtain signal strength information related to a connection strength between the robot cleaner and a plurality of electronic devices disposed in the space, respectively, at the plurality of measurement locations;
• storing the signal strength information in correspondence to the plurality of measurement locations;
• based on the stored signal strength information, identifying a measurement location at which a signal strength of the plurality of electronic devices is a threshold value or more, as a recommended AP location of the AP device, among the plurality of measurement locations;
• and
• providing, to a user terminal device, the signal strength information that was stored in correspondence to the plurality of measurement locations and an AP location recommendation user interface (UI) configured to display, on the user terminal device, the recommended AP location on the map.
