Patent number: 11474533Abstract: A method for a robotic cleaning device of detecting a difference in level of a surface in front of the robotic cleaning device moves. The method includes illuminating the surface with light, capturing an image of the surface, detecting a luminous section in the captured image caused by the light, identifying at least a first segment and a second segment representing the detected luminous section, and detecting, from a positional relationship between the identified first and second segment, the difference in level of the surface.Type: GrantFiled: June 2, 2017Date of Patent: October 18, 2022Inventors: Petter Forsberg, Magnus Lindhé, Andreas Klintemyr

Publication number: 20220287522Abstract: An autonomous cleaning robot having a body, a driving means configured to move the robot in a forward direction over a surface being cleaned, a suction opening arranged at an underside of the body, and a roller arranged at the underside of the body and in front of the suction opening, relative the forward direction. The roller is configured to define a front air passageway at the surface, and comprises bristles arranged to form a front air barrier restricting an air flow in the front air passageway. The front air barrier is configured to be substantially uniform over an entire turn of the roller, wherein the bristles are further arranged to direct the air flow towards a particle passing by the roller, and further into the suction opening.Type: ApplicationFiled: September 4, 2019Publication date: September 15, 2022Applicant: Aktiebolaget ElectroluxInventors: Jens Leffler, Magnus Wennerström, Andreas Klintemyr

Patent number: 10874271Abstract: A side brush for a robotic cleaner. The side brush is rotatable about a rotation axis in a rotational direction and has a brush body and numerous linear bristles including a first bristle having a base end at the brush body and an opposite distal end. An imaginary line extends perpendicularly to the rotation axis. The first bristle extends in a bristle direction outwardly from the brush body. Seen in a top view, the bristle direction extends at a first angle to the imaginary line with the distal end pointing rearwardly in relation to the rotational direction. Seen in a side view, the bristle direction extends at a second acute angle to the rotation axis pointing away from the brush body. A robotic cleaner having such a side brush is also disclosed herein.Type: GrantFiled: December 12, 2014Date of Patent: December 29, 2020Assignee: AKTIEBOLAGET ELECTROLUXInventors: Daniel Kastensson, Andreas Klintemyr

Patent number: 10729297Abstract: A robotic vacuum cleaner having a nozzle inlet facing a surface to be cleaned, and a rotatable side brush. The rotatable side brush has bristles extending substantially in parallel with the surface to be cleaned, and the nozzle inlet includes a frame structure forming an opening, the opening being arranged in fluid communication with a debris receptacle. The bristles extend over a side portion of the nozzle inlet. The frame structure has a base portion extending substantially in parallel with the surface to be cleaned. The base portion extends at a first level. The frame structure at the side portion extends substantially in parallel with the surface to be cleaned at a second level. The first level is arranged closer to the surface to be cleaned than the second level.Type: GrantFiled: September 8, 2014Date of Patent: August 4, 2020Assignee: AKTIEBOLAGET ELECTROLUXInventors: Andreas Klintemyr, Anders Haegermarck, Daniel Kastensson

Publication number: 20200031226Abstract: A robotic cleaning device having a propulsion system to move the robot over a surface to be cleaned, a controller to control the propulsion system to cause the robot to perform a rotating movement, and an inertial measurement unit configured to measure a change in heading of the robotic cleaning device caused by the rotating movement. The controller is further configured to acquire signals from an odometry encoder arranged on each drive wheel of the propulsion system for measuring the change in heading of the robotic cleaning device caused by the rotating movement, and to determine a relation between the change in heading measured using odometry and the change in heading measured using the angle-measuring device, wherein a difference in the two measured changes in heading indicates an estimate of wheel slip that occurs on said surface.Type: ApplicationFiled: March 15, 2017Publication date: January 30, 2020Inventors: Anders Haegermarck, Petter Forsberg, Magnus Lindhe, Andreas Klintemyr

Patent number: 10433697Abstract: A method of controlling rotating side brushes of a robotic cleaning device and a robotic cleaning device performing the method. The robotic cleaning device has a main body, a propulsion system arranged to move the robotic cleaning device across a surface to be cleaned, and a controller arranged to control the propulsion system to move the robotic cleaning device across the surface to be cleaned in accordance with navigation information. The robotic cleaning device has an opening arranged in a bottom side of the main body via which debris is removed from the surface to be cleaned, and at least one rotating side brush adjacent to the opening. The controller registers a speed with which the robotic cleaning device moves across the surface to be cleaned, and controls a rotational speed of the rotating side brush on the basis of the registered speed of movement of the robotic cleaning device.Type: GrantFiled: December 19, 2013Date of Patent: October 8, 2019Assignee: Aktiebolaget ElectroluxInventors: Magnus Lindhé, Andreas Klintemyr, Anders Haegermarck, Petter Forsberg
