Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S).

Method and apparatus for reusing wastewater

Disclosed is a cleaning robot for creating a 3Dimensional (3D) obstacle map including information about a height of an object existing on an area to be cleaned, and cleaning the area to be cleaned based on the 3D obstacle map, and a method of controlling the cleaning robot. In accordance with an aspect of the present disclosure, there is provided. The cleaning robot includes a main body, a moving portion configured to move the main body, an obstacle sensor configured to sense a height of an obstacle, and a controller configured to create an obstacle map including information about the height of the obstacle.

Cleaning robot and controlling method thereof

A cleaning robot may include a main body, a driver configured to move the main body, a cleaner configured to clean a cleaning space, and a controller configured to set at least one area among a plurality of areas included in the cleaning space as a cleaning area while the main body moves, and clean the cleaning area when the cleaning area is set.

Cleaning robot and control method thereof

A robot cleaner includes a main body, a traveling unit installed in the main body, to move the main body, an ultrasonic sensor to emit an oscillation wave, to receive a reflection wave reflected from an object surface, and to output vibration generated by the oscillation wave and vibration generated by the reception of the reflection wave as an electrical signal, a waveform analyzer to calculate a generation time period of the electrical signal output from the ultrasonic sensor, and a controller to determine information about the object surface based on the calculated generation time period of the electrical signal, and to control movement of the traveling unit based on the information about the object surface.
