Abstract: A system for controlling an unmanned aerial vehicle (UAV) to switch between different flight modes during operation. The system includes one or more processors configured to determine, based on sensor data received from one or more sensors carried by the UAV, a change in environment of the UAV from a first environment type to a second environment type. In response to determining the change in environment, the one or more processors configured to switch a flight mode of the UAV from a first flight mode to a second flight mode, and effect operation of the UAV in accordance with a second set of operating rules for operating in the second environment type.

Abstract: A method of determining a flight path for an aerial vehicle includes identifying during flight a change in a state of signal transmission occurring at a first location, and, in response to identifying the change, selecting a first destination within a proximity of a second location. A state of signal transmission at the second location during a previous flight is different from a state of signal transmission at the first location. The method further includes determining a first flight path to reach the first destination. The first flight path comprises accessible locations detected by one or more sensors onboard one or more aerial vehicles. The method also includes, upon reaching the first destination by the aerial vehicle, assessing in real time a state of signal transmission at the first destination, and determining a second flight path to a second destination based on the assessment.

Abstract: A method of controlling an unmanned aerial vehicle (UAV) includes receiving an image from one or more vision sensors of the UAV. The image is captured while the UAV is in flight and includes a marker within an environment. The marker has a visual pattern. The method further includes identifying the visual pattern to determine a plurality of instructions encoded in the visual pattern, and controlling, in response to the plurality of instructions, the UAV to perform an action including at least one of adjusting position of a payload, swapping a payload, or capturing an image of a selected subject.
