Publication number: 20230123512Abstract: A method of moving a robotic cleaning device through an area includes loading instructions for a plurality of geometric elements. Each geometric element includes a starting point, paths of travel, and waypoints. An ending waypoint of a first geometric element is connected to the starting point for a subsequent geometric element. The instructions for each geometric element do not include dimensions for the one or more paths of travel. The instructions cause the robotic cleaning device to move along a first path of travel of the first geometric element until a sensor of the robotic cleaning device detects that the robotic cleaning device has reached a first waypoint. Then, if the first waypoint is the ending waypoint of the first geometric element, the robotic cleaning device moves along to the subsequent geometric element or changes direction and moves along a second path of travel of the first geometric element.Type: ApplicationFiled: December 20, 2022Publication date: April 20, 2023Inventors: David M. Knuth, JR., Aurle Y. Gagne, Erick Frack, Daniel M. Daly

Patent number: 11537141Abstract: A system dynamically generates a cleaning coverage pattern of an area using waypoints and sensor data from one or more sensor modalities. To do this, a robotic cleaning device moves through an area to be cleaned, identifies consecutive waypoints through the area, and stores the waypoints in a memory. At least one sensor of the robotic cleaning device collects sensor data about a portion of the area as the device moves between the consecutive waypoints. A temporary map of the portion of the area between the consecutive waypoints is generated based on the collected sensor data, and a cleaning coverage pattern is generated using the temporary map. The area is then cleaned by moving the robotic cleaning device according to the cleaning coverage pattern. In certain embodiments, upon completing the cleaning, the consecutive waypoints are retained in the memory, while the temporary map may not be retained.Type: GrantFiled: December 19, 2019Date of Patent: December 27, 2022Assignee: Diversey, Inc.Inventors: David M. Knuth, Jr., Aurle Y. Gagne, Erick Frack, Daniel M. Daly

Patent number: 11402850Abstract: A system and method of causing a robotic device to navigate an area, including accessing a map of an area of travel, causing a transport assembly of the robotic device to move the robotic device in the area at a first speed, collecting information about the area as the robotic device moves in the area by at least one sensor, and processing the information collected. The system and method also include comparing the information collected with the information regarding the area from the map, and determining a degree of confidence that the information collected matches the information regarding the area of travel from the map. When the determined degree of confidence is at or below a first threshold degree of confidence, a first reduced speed mode of operation causes the transport assembly of the robotic device to move at a second, lower speed.Type: GrantFiled: December 8, 2017Date of Patent: August 2, 2022Assignee: Diversey, Inc.Inventors: Aurle Gagne, Philip Scarim, David M.

Publication number: 20210191415Abstract: A robotic device is used to generate a map of a facility. A processor will receive a facility description that includes an initial path and one or both of the following: a first number of navigable openings that are positioned along the initial path, or a first number of barriers that are positioned along the initial path. The robotic device will move along the initial path. As this happens, one or more sensors of the robotic device will capture a data set of sensed characteristics of the facility. The processor will analyze the data set to detect navigable openings along the initial path, and it will assign an identifier to each navigable opening. The processor will use the identifiers of the navigable openings to develop a map of the facility that includes the navigable openings. The processor will save the map to a data store.Type: ApplicationFiled: December 19, 2019Publication date: June 24, 2021Inventors: Aurle Y. Gagne, David M. Knuth, JR., Philip Scarim

Patent number: 9609991Abstract: A method of cleaning an area using an automatic cleaning device may include receiving, from a video camera, information associated with an edge located on a surface, determining, by an automatic cleaning device, a position of the automatic cleaning device on the surface relative to the edge and using the received information to move the automatic cleaning device from the determined position along a path so that the automatic cleaning device cleans the surface along the path. The path may be substantially parallel to the edge, and the edge may be located a distance from a reference point on the automatic cleaning device during movement of the automatic cleaning device.Type: GrantFiled: February 10, 2014Date of Patent: April 4, 2017Assignee: Diversey, Inc.Inventors: Henry L.

Publication number: 20160360940Abstract: A method of causing a mobile robotic device, such as an automated cleaning device, to navigate an area includes using a video camera to collect visual information associated with an area in which a mobile robotic device is located. A system receives information from the video camera, wherein the information comprises a value associated with a detected color in the area. The system compares the value associated with the detected color to a value of a requested color, and the system determines whether the value associated with the detected color is within a tolerance range of the value of the requested color. If the value associated with the detected color is within a tolerance range of the value of the requested color, the system accepts the color. The system uses the received information to adjust a position of the mobile robotic device in the area.Type: ApplicationFiled: August 11, 2016Publication date: December 15, 2016Inventors: Henry L.

Patent number: 8958937Abstract: A floor cleaning machine includes a set of obstacle sensors that detect when the machine is approaching an obstacle. If the obstacle is less than a threshold distance away from the machine, the machine may output an alert and override the operator's command with a command to reduce the speed of the machine. If the obstacle is less than a minimum threshold distance away from the machine, the machine may come to a complete stop to prevent the collision.Type: GrantFiled: March 12, 2013Date of Patent: February 17, 2015Assignee: Intellibot Robotics LLCInventors: Henry L.
