    Abstract: A moving robot includes a main body which forms a space therein, a noise generating member which is disposed inside the main body and generates a noise, an inner housing and an outer housing which surround the main body, and two or voice recognition members which are disposed in the housing and are disposed to be separated from each other, and a noise recognition member which recognizes a noise. The voice recognition members are disposed on a side opposite to the noise generating member based on a central point and disposed to be separated from each other along an outer peripheral surface of the housing. Accordingly, a voice command is determined by a difference of the voice data acquired by the two voice recognition members separated from each other and noise data recognized by the noise recognition member to improve voice recognition efficiency.

    Abstract: The present disclosure relates to a laundry treatment machine. A laundry treatment machine comprises: an inverter to convert the DC voltage from the converter into alternating current (AC) voltage by a switching operation and to output the converted AC voltage to a motor; and a controller that controls such that, while a washing tub motor is rotating at a constant speed, a drain motor operates in a first period during which the speed of the drain motor increases, a second period during which the speed of the drain motor decreases after the first period, and a third period during which the speed of the drain motor decreases after the second period, wherein a rising slope in the second period is less than a falling slope in the third period. Accordingly, a speed ripple of the drain motor may be reduced.
