Abstract:
The invention relates to a method of controlling rotating side brushes of a robotic cleaning device and a robotic cleaning device performing the method. The robotic cleaning device comprises a main body (11), a propulsion system (12, 13, 15a, 15b) arranged to move the robotic cleaning device across a surface to be cleaned, and a controller (16) arranged to control the propulsion system to move the robotic cleaning device across the surface to be cleaned in accordance with navigation information. Further, the robotic cleaning device comprises an opening (17) arranged in a bottom side of the main body via which opening debris is removed from the surface to be cleaned and at least one rotating side brush (24) arranged adjacent to the opening. The controller is arranged to register a speed with which the robotic cleaning device moves across the surface to be cleaned, and further to control rotational speed of the rotating side brush on the basis of the registered speed of movement of the robotic cleaning device.
Abstract:
A mobile surface cleaning robot (100) including a robot body ( 110) having a forward drive direction (F) and a drive system (120) supporting the robot body above a floor surface (10). The drive system (120) includes right and left drive wheels (124a, 124b) and a caster wheel assembly (126) disposed rearward of the drive wheels. The caster wheel assembly includes a caster wheel (127a) supported for vertical movement and a suspension spring (127b) biasing the caster wheel toward the floor surface. The robot also includes a cleaning system (160) supported by the robot body forward of the drive wheels and having at least one cleaning element (310) that engages the floor surface. The suspension spring (127b) has a spring constant sufficient to elevate a rear end (116) of the robot body above the floor surface to maintain engagement of the at least one cleaning element with the floor surface.
Abstract:
A mobile floor cleaning robot (100) includes a robot body (110) supported by a drive system (120) configured to maneuver the robot over a floor surface (10). The robot also includes a cleaning system (160) supported by the robot body, an imaging sensor (510) disposed on the robot body, and a controller (150) in communication with the drive system and the imaging sensor. The controller receives a sequence of images (514b) of the floor surface. The controller segments each image into color blobs (23) by color quantizing pixels (514) of the image, determines a spatial distribution of each color of the image based on corresponding pixel locations (517), and identifies areas of the image having a threshold spatial distribution for that color. The controller then tracks a location (12a) of the color blobs with respect to the imaging sensor across the sequence of images.
Abstract:
The present invention relates to a robot cleaner. The robot cleaner according to an aspect comprises: a casing having a suction port; a suctioning member installed in the casing and suctioning external foreign substances through the suction port; a driving member moving the casing; and a side brush assembly movably installed on the casing, wherein the side brush assembly includes a brush allowing foreign substances in a region outside the casing to move toward the suction port by rotation of the side brush assembly, and a rotational axis of the brush can be moved horizontally.
Abstract:
Die Erfindung betrifft ein Verfahren zur Bearbeitung einer textilen Bodenfläche, insbesondere eines hochflorigen Teppichs oder Teppichbodens, mit einem selbstfahrenden und selbstlenkenden Bodenreinigungsgerät, das eine Antriebseinheit, eine Steuereinheit zum Steuern der Bewegung des Bodenreinigungsgerätes und eine Bodenreinigungseinheit mit mindestens einer elektromotorisch antreibbaren Reinigungsbürste aufweist. Um ein derartiges Verfahren bereitzustellen, mit dem eine möglichst gründliche Reinigung der textilen Bodenfläche durchführbar ist, wird vorgeschlagen, dass anhand mindestens eines Sensors einer Sensoreinheit des Bodenreinigungsgerätes ein mit einer Florrichtung der Bodenfläche verknüpftes Sensorsignal erfasst und an ein Florrichtungsermittlungsglied des Bodenreinigungsgerätes übertragen wird, vom Florrichtungsermittlungsglied anhand des Sensorsignals die Florrichtung der Bodenfläche ermittelt wird und die Bodenfläche in Abhängigkeit von der ermittelten Florrichtung bearbeitet wird. Außerdem betrifft die Erfindung ein selbstfahrendes und selbstlenkendes Bodenreinigungsgerät.

Abstract:
A method of cleaning a surface using an automatic cleaning device may include learning, by an automatic cleaning device, one or more cleaning methods. Each cleaning method may be associated with a code corresponding to a radio frequency identification tag positioned in a vicinity of a surface to be cleaned. The method may also include receiving, by the automatic cleaning device, a target code from a target radio frequency identification tag positioned in a vicinity of a target surface to be cleaned, determining the cleaning method associated with the target code and applying the associated cleaning method to the target surface when the target radio frequency identification tag is detected.
Abstract:
A cleaning device for cleaning windows comprises an elongate wiper element (C) which is robotically controlled to move across the surface of the window to apply and remove cleaning fluid therefrom. The robotic control can be so arranged that the movement of the wiper element corresponds to that which it would follow if used manually by a skilled window cleaner.
