    Abstract: Described are systems and methods to utilize an objective function of an aerial vehicle in constructing and/or updating an occupancy map. The described systems and methods can determine whether to include, add, and/or remove an object from an occupancy map based on one or more confidence score(s) that can be determined for the presence (or absence) of an object at a given location. The confidence score for an object at a given location can be determined, for example, based on various sources of information, which can each be provided different weights, parameters, thresholds, etc. based on the objective function of the aerial vehicle.

    Abstract: Disclosed are methods and systems for delivery of items using an unmanned aerial vehicle (“UAV”). A user may be provided with a delivery location identifier (“DLI”) that is to be placed at a delivery location within a delivery destination to identify where a UAV is to position an item as part of a delivery to the delivery destination. For example, the delivery destination may be a user's home. Within the deliver destination of the user's home, the user may select a delivery location, such as a spot in the back yard wherein the UAV is to position the ordered item as part of the delivery. To aid the UAV in navigating to the delivery location, the user places the DLI at the delivery location. The UAV detects the DLI and positions the item at or near the DLI as part of the item delivery.

    Abstract: Systems and methods for providing a multi-direction wind tunnel, or “windball,” are disclosed. The system can have a series of fans configured to provide air flow in a plurality of directions to enable accurate testing of aircraft, unmanned aerial vehicles (UAVs), and other vehicles capable of multi-dimensional flight. The system can comprise a spherical or polyhedral test chamber with a plurality of fans. The fans can be arranged in pairs, such that a first fan comprises an intake fan and a second fan comprises an exhaust fan. The direction of the air flow can be controlled by activating one or more pairs of fans, each pair of fan creating a portion of the air flow in a particular direction. The direction of the air flow can also be controlled by rotating one or more pairs of fans with respect to the test chamber on a gimbal device, or similar.
