  • Patent number: 11537141
    Abstract: 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.

  • Patent number: 11484899
    Abstract: A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

  • Patent number: 11402850
    Abstract: 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.
