    Abstract: A device may receive images identifying interiors of buildings and movable objects and unmovable objects located in the interiors, and may train a machine learning model with the images to generate a trained machine learning model. The device may receive an image identifying an interior portion of a building and objects located in the interior portion, and may process the image, with the trained machine learning model, to identify a movable object and an unmovable object. The device may disregard the movable object to generate an image in which data identifying the movable object has been disregarded, and may process the image in which the data identifying the movable object has been disregarded, with a visual positioning system, to determine a location of the user device in the interior portion of the building. The device may perform one or more actions based on the location of the user device.

    Abstract: In some implementations, a device may receive spatial data corresponding to an interior of a building and objects located in the interior of the building. The device may generate a digital map of the interior of the building based on the spatial data. The device may generate a geographic coordinate map of the interior of the building. The device may receive, from a sensor mounted on an uncrewed aerial vehicle (UAV), sensor data indicating three-dimensional geographic points. The device may compare the sensor data to the geographic coordinate map to localize the UAV on the geographic coordinate map. The device may generate coordinate data indicating geographic coordinates associated with the geographic coordinate map and formatted in a global positioning system coordinate format and a National Marine Electronics Association format. The device may transmit, to a controller of the UAV, at least a subset of the coordinate data.

    Abstract: In some implementations, a device may receive status information for robotic devices. The status information may include locations and navigation plans of the robotic devices. The device may monitor, based on the status information, individual statuses of the robotic devices. The device may receive a mission request associated with performance of an operation. The device may select, based on the individual statuses, a first robotic device to perform the operation. The device may determine, based on a mapping of an environment, potential navigation plans associated with the first robotic device traversing the environment according to the operation. The device may select a navigation plan based on the locations and the navigation plans of the robotic devices. The device may stream navigation instructions associated with the selected navigation plan to the first robotic device to cause the first robotic device to traverse the environment according to the navigation plan.

    Abstract: A device may establish a first connection to a first radio access network (RAN) associated with a first radio access technology (RAT). The device may register to receive a call service via the first RAN. The device may receive the call service via the first connection. The device may establish a second connection to a second RAN associated with a second RAT that is different from the first RAT. The device may register to receive the call service via the second RAN. The device may compare a first signal quality metric, associated with the first connection, and a second signal quality metric associated with the second connection. The device may cause the call service to be transferred from the first connection to the second connection, based on comparing the first signal quality metric and the second signal quality metric, without causing an interruption to the call service.
