Patent number: 11525921Abstract: 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.Type: GrantFiled: April 3, 2019Date of Patent: December 13, 2022Assignee: SharkNinja Operating LLCInventors: Adam Leech, Frederick K. Hopke, Isaku D. Kamada

Patent number: 11442454Abstract: An adaptive sensor array system and method includes receiving one or more signals from a sensor array and compare the received signals to one or more object detection threshold values, determining if the robotic cleaner was moving along a travel path for a predetermined period of time, window W, in response to a determination that the robotic cleaner was operating in straight-line motion during the window W, calculating a value of the received detected signals from the sensor array during one or more calibration periods C of the window W, and adjusting one or more of the object detection threshold values based on the calculated value during the window W. A sum of all the calibration periods C during window W is less than a length of the window W. One of the calibration periods C may start at a beginning of the window W.Type: GrantFiled: March 20, 2020Date of Patent: September 13, 2022Assignee: SharkNinja Operating LLCInventors: Alex Irkliy, Charles Fiebig, Isaku D. Kamada, Xavier F. Cullere, Charles S. Brunner, Brian Burke

Patent number: 11191403Abstract: A docking station for a robotic cleaner may include a base, a docking station dust cup removably coupled to the base, a latch actuatable between a retaining position and a release position, and a release system configured to actuate the latch between the retaining and release positions. The docking station dust cup may be removable from the base in response to a pivotal movement of the docking station dust cup relative to the base about a pivot point. The latch may be horizontally spaced apart from the pivot point, wherein, when the latch is in the retaining position, pivotal movement of the docking station dust cup is substantially prevented.Type: GrantFiled: July 19, 2019Date of Patent: December 7, 2021Assignee: SharkNinja Operating LLCInventors: Aaron Gill, David Harting, Hamish Thompson, Christopher Meyer-Rassow, Catriona C.
