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.
