  • Robotic cleaning device with operating speed variation based on environment
    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.
