Abstract: An optical beacon may include a housing, an optical emitter at least partially disposed within the housing, and an optical identifier generator optically coupled to the optical emitter. Light incident on the optical identifier generator may be shaped into at least one optical identifier. The optical identifier may be associated with an action capable of being carried out by a robotic cleaner such that detection of the optical identifier by the robotic cleaner causes the robotic cleaner to carry out the action.

Abstract: A robotic cleaner may include a body, one or more driven wheels configured to urge the body across a surface to be cleaned, one or more distance sensors disposed at least partially within the body such that the one or more distance sensors face the surface to be cleaned and a processor. The one or more distance sensors may be configured to output a measure of a detection distance that extends in a direction of the surface to be cleaned. The processor may be configured to determine whether an abnormality has been detected based, at least in part, on the measure of the detection distance and may be configured to determine a first velocity estimate based, at least in part, on the detection of the abnormality.

Abstract: In general, the present disclosure is directed to a time of flight (ToF) sensor arrangement that may be utilized by a robot (e.g., a robot vacuum) to identify and detect objects in a surrounding environment for mapping and localization purposes. In an embodiment, a robot is disclosed that includes a plurality of ToF sensors disposed about a housing of the robot. Two or more ToF sensors may be angled/aligned to establish overlapping field of views to form redundant detection regions around the robot. Objects that appear therein may then be detected by the robot and utilized to positively identify, e.g., with a high degree of confidence, the presence of the object. The identified objects may then be utilized as data points by the robot to build/update a map. The identified objects may also be utilized during pose routines that allow the robot to orient itself within the map.

Abstract: A beacon for a robotic cleaner may include a housing and an optical indicium having an optical pattern. The optical indicium may be coupled to the housing and be viewable by a camera of the robotic cleaner. After observing the optical indicium, the robotic cleaner may be caused to carry out an action associated with at least a portion of the optical pattern.
