  • Patent number: 10310507
    Abstract: A method of operating a mobile robot includes generating a segmentation map defining respective regions of a surface based on occupancy data that is collected by a mobile robot responsive to navigation of the surface, identifying sub-regions of at least one of the respective regions as non-clutter and clutter areas, and computing a coverage pattern based on identification of the sub-regions. The coverage pattern indicates a sequence for navigation of the non-clutter and clutter areas, and is provided to the mobile robot. Responsive to the coverage pattern, the mobile robot sequentially navigates the non-clutter and clutter areas of the at least one of the respective regions of the surface in the sequence indicated by the coverage pattern. Related methods, computing devices, and computer program products are also discussed.

  • Patent number: 10182693
    Abstract: A piezoelectric debris sensor and associated signal processor responsive to debris strikes enable an autonomous or non-autonomous cleaning device to detect the presence of debris and in response, to select a behavioral mode, operational condition or pattern of movement, such as spot coverage or the like. Multiple sensor channels (e.g., left and right) can be used to enable the detection or generation of differential left/right debris signals and thereby enable an autonomous device to steer in the direction of debris.

  • Patent number: 10159180
    Abstract: A method of mowing multiple areas includes training a robotic mower to mow at least two areas separated by a space, including moving the robotic mower about the areas while storing data indicative of location of boundaries of each area relative to boundary markers, training the robotic mower to move across the space separating the areas, and initiating a mowing operation. Training the robotic mower to move across the space separating the areas includes moving the robotic mower to a traversal launch point of a first of the areas and moving the robotic mower to a traversal landing point of a second of the areas. The mowing operation causes the robotic mower to move to the traversal launch point, move from the traversal launch point across the space to the traversal landing point, and then mow the second of the areas.
