Abstract:
PROBLEM TO BE SOLVED: To provide a cleaning robot capable of executing higher-efficiency cleaning operation by enabling easy guidance to an optional position desired by a user.SOLUTION: A cleaning robot 1 includes: a body housing 2 self-traveling on a floor surface with a suction port 6 and an exhaust port 7 opened; a motor fan 22 disposed inside the body housing 2; a dust collection part 30 collecting dust of an airflow sucked from the suction port 6 by the drive of the motor fan 22; an infrared remote controller 60 designating the optional position of a setting space of the body housing 2 by emitting infrared rays; and an infrared sensor 18 detecting the designation position designated by the infrared remote controller 60. The cleaning robot 1 executes the cleaning operation after moving to the designation position detected by the infrared sensor 18 and/or while moving to the designation position.

PROBLEM TO BE SOLVED: To provide a driving wheel assembly having a structure improved to stably drive regardless of the status and conditions of a floor surface, and to provide a robot cleaner provided with the driving wheel assembly.SOLUTION: The robot cleaner includes a body and a driving wheel assembly. The driving wheel assembly includes: a driving wheel, a housing, a driving motor, a rotating member that rotates on the rotation axis of the driving motor and has a first part and a second part disposed at positions opposite to the driving wheel centering the rotation axis of the driving motor; and a compression coil spring that is disposed between the housing and the second part and pressurizes the second part. In the robot cleaner, the distance between a contact point where the compression coil spring and the second part come in contact to each other, and the rotation axis of the driving motor is shorter than the distance between the rotation axis of the driving wheel and the rotation axis of the driving motor.

PROBLEM TO BE SOLVED: To provide a robot cleaner which does not stop to change a traveling direction thereof and which can reduce a time required to clean a cleaning area, and a control method thereof.SOLUTION: A robot cleaner sets a territory in which cleaning is performed on the basis of position data acquired while traveling a cleaning area, and presets a cleaning path to clean the territory in which the cleaning is performed. If the cleaning path includes a zigzag traveling path, the robot cleaner changes a direction thereof by executing curved traveling during traveling along the zigzag traveling path, thereby reducing a time required to clean the clearing area.

PROBLEM TO BE SOLVED: To prevent a robot cleaner from being operated when a dust tank is separated from a body by detecting separation of the dust tank from the body. SOLUTION: A robot cleaner comprises: a body having a receiving portion for mounting a dust tank; a detecting unit installed at the receiving portion, for detecting whether the dust tank has been separated from the body by an interaction with the dust tank; and a controller for controlling a suction motor installed in the body according to a detection result.

Abstract:
A robot cleaner, a robot cleaning system and a method for controlling the same that is capable of independently determining whether a cleaning work in a work area is completed. This is accomplished by providing a robot cleaner for performing cleaning work by communicating wirelessly with an apparatus external to the robot cleaner, comprising a main body provided with a suction unit for collecting dust on a floor to be cleaned, a driving unit disposed on the main body for driving a plurality of wheels, an upward-looking camera disposed on a top of the main body for photographing images of a ceiling perpendicular to a direction of driving the robot cleaner, an obstacle detection sensor disposed on a front of the main body for detecting an obstacle positioned ahead of the robot cleaner in the driving direction, a memory for storing position information of the obstacles detected by the obstacle detection sensor; and a control unit for calculating position information of the obstacle to store the calculated obstacle position information in the memory upon receiving an obstacle detection signal from the obstacle detection sensor, determining whether the obstacle position information stored at the memory forms a closed curve, and further controlling the driving unit to drive the robot cleaner along a predetermined driving pattern, wherein the control unit stops the suction unit from operating when the obstacle position information forms a closed curve.
Abstract:
PROBLEM TO BE SOLVED: To provide a self-propelled vacuum cleaner which can perform comfortable cleaning with low power consumption and at low noise while keeping high dust-collecting property. SOLUTION: The self-propelled vacuum cleaner can perform comfortable cleaning with low power consumption and at low noise by operating a side brush only while cleaning the vicinity of a wall or an obstacle to improve the dust-collecting property in cleaning of a place where dust is accumulated easily but stopping the operation of the side brush when cleaning the other places. A judgment detection part 15 detects approach of the wall or the obstacle based on a detection signal from an obstacle detection part 14. According to the detection of the approach, the judgment detection part 15 instructs rotation at the place, changing of a moving direction or travelling near the wall to a travel navigation part 16. The judgment detection part 15 outputs instruction of driving the side brush only during rotation and travelling near the wall and stopping the side brush during the other straight moving to a side brush driving part 11.
