    Abstract: An electronic device and network scan method thereof are provided. The electronic device includes a communication module connected to an antenna capable of transmitting signals to and receiving signals from a network, a memory configured to store a database including a plurality of items of network identification information and country information corresponding to each item of network identification information, and a processor configured to control the communication module to perform a first network scan with respect to a specified frequency band of a specified radio access technology (RAT), determine country information using network identification information obtained by the first network scan and the database, and perform a second network scan with respect to a RAT and a frequency band determined based at least an the determined country information.

    Abstract: Disclosed herein is a cleaning robot including an improved driving unit to escape from an undriveable state occurring under various driving conditions. The cleaning robot includes a body, and a driving unit that drives the body. The driving unit includes a first driving motor and a second driving motor that generate driving power; a driving wheel that rotates when the driving power is delivered to the driving wheel from the first driving motor; and a wheel frame that supports the driving wheel to be rotatable and rotates between a first position and a second position with respect to a motor shaft of the first driving motor. The wheel frame rotates in at least one section between the first position and the second position when the driving power is delivered to the wheel frame from the second driving motor.
