Abstract: Disclosed are a robot cleaner capable of controlling a water pump of a robot cleaner by a user input through an external control device, a robot cleaning system having the same, and a control method of the robot cleaning system. According to the present invention, user convenience is increased since the amount of water supplied to the mop of the robot cleaner can be controlled according to a cleaning environment, cleaning efficiency is improved by controlling the water pump to quickly wet the mop of the robot cleaner at the beginning of a cleaning operation, and the robot cleaner can be hygienically managed since a user controls the water pump to discharge residual water inside the robot cleaner.

Abstract: A mobile robot and a control method therefor, according to the present invention, are configured to determine whether a received signal is a pre-set signal and distinguish noise caused by overlapping of signals to control the operation of a sensor for detecting an obstacle according to an operation state of a main body such that transmission of a detection signal is limited, and thus has effects of the obstacle being easily detected by distinguishing each signal, the main body returning to a charging stand, and signal interference being minimized for a plurality of sensors using a signal of the same wavelength band.
