Abstract: A cleaning robot and a control method thereof may improve power consumption efficiency by using low-voltage power for a moving or inspecting operation and performing the moving or inspecting operation while operation of the cleaning unit is stopped when the operation of the cleaning unit is not needed. The cleaning robot includes a battery, a moving unit, a cleaning unit, a power converter which converts and outputs power supplied from the battery into a first voltage driving the moving unit and a second voltage driving the cleaning unit, and a controller which supplies power having the first voltage to the moving unit so as to drive the moving unit and supplies power having the second voltage to the cleaning unit so as to perform a cleaning operation. The controller continues driving the moving unit but stops driving the cleaning unit when the cleaning robot moves on an already cleaned area.

Abstract: A robot cleaner capable of vacuuming foreign materials on a floor includes a main body to which a dust collector is mounted and a vacuuming unit provided at a front portion of the main body to clean a floor. The vacuuming unit is configured to move relative to the main body. If it is determined that the robot cleaner is located near a wall or an obstacle, the vacuuming unit moves to the wall or the obstacle. Since the vacuuming unit contacts the wall or the obstacle, a region of a floor near the wall or the obstacle may be cleaned. Further, a manual cleaner may be selectively connected to a channel connector of the robot cleaner so that a user may choose automatic or manual cleaning of a floor at the user's convenience.

Abstract: A device and control method for driving a sensorless brushless DC (BLDC) motor, particularly related to a technology configured to increase the accuracy of detection of Zero Cross Point through a non-commutation period in a pulse width modulation (PWM) control. The device for driving a sensorless BLDC motor to switch a current applied to a stator winding based on a position of a rotor includes a three phase inverter configured to convert a DC input voltage into a three phase AC voltage and supply the three phase AC voltage to the BLDC motor; a terminal voltage detector configured to detect a three phase terminal voltage from an output terminal of the three phase inverter; and a controller configured to perform a PWM control of the terminal voltage based on a three phase back electromotive force (EMF) included in the detected terminal voltage. The PWM control includes a non-commutation control in which the switching of the current does not occur.
