Abstract: This disclosure describes a system and method for operating an automated aerial vehicle wherein influences of a ground effect may be utilized for sensing the ground or other surfaces. In various implementations, an operating parameter of the automated aerial vehicle may be monitored to determine when a ground effect is influencing the parameter, which correspondingly indicates a proximity to a surface (e.g., the ground). In various implementations, the ground effect based sensing techniques may be utilized for determining a proximity to the ground, as a backup for a primary sensor system, for determining if a landing location is uneven, etc.

Abstract: This disclosure describes an automated aerial vehicle that includes one or more object detection elements configured to detect the presence of objects and an avoidance determining element configured to cause the automated aerial vehicle to automatically determine and execute an avoidance maneuver to avoid the objects. For example, an object may be detected and an avoidance maneuver determined based on a position of the object and an object vector representative of a direction and a magnitude of velocity of the obj ect.

Abstract: Sounds are generated by an aerial vehicle (101) during operation. For example, the motors and propellers (102) of an aerial vehicle (101) generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the position of one or more propeller blade treatments (202) of a propeller blade (200) of an aerial vehicle (101) during operation of the aerial vehicle (101). For example, the propeller blade (200) may have one or more propeller blade treatments (202) that may be adjusted between two or more positions. Based on the position of the propeller blade treatments (202), the airflow over the propeller (102) is altered, thereby altering the sound generated by the propeller (102) when rotating. By altering the propeller blade treatments (202) on multiple propeller blades (200) of the aerial vehicle (101), the different sounds generated by the different propeller blades (200) may effectively cancel, reduce, and/or otherwise alter the total sound generated by the aerial vehicle (101).

Abstract: Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the position and/or configuration of one or more propeller blades of a propulsion mechanism to generate different sounds and/or lifting forces from the propulsion mechanism. A propulsion apparatus, comprising a motor (206), a propeller having a propeller blade (204) and a propeller adjustment controller configured to enable movement of the propeller such that the propeller blade (204) is extendable away from the motor (206) or retractable toward the motor (206). A method for adjusting a propulsion mechanism, comprising: determining a lifting force to be generated by the propulsion mechanism; determining a sound limit to be produced by the propulsion mechanism; selecting a combination of a revolutions per minute ("RPM") of a motor of the propulsion mechanism, a first position of a first propeller of the propulsion mechanism that will generate a first lifting force when rotated by the motor at the RPM, a second position of a second propeller of the propulsion mechanism that will generate a second lifting force when rotated by the motor at the RPM and a third position of a third propeller of the propulsion mechanism that will generate a third lifting force when rotated by the motor at the RPM such that a combination of the first lifting force, the second lifting force, and the third lifting force will generate the lifting force and produce a sound below the sound limit; causing, while the motor is rotating: the first propeller to move to the first position; the second propeller to move to the second position; and the third propeller to move to the third position.

Abstract: A motor mount assembly is provided for coupling a propeller motor to a body of an unmanned aerial vehicle (UAV). The motor mount assembly includes a floating portion and acts to attenuate frequencies of vibration from the propeller motor during operation, which modifies the corresponding noise that is produced and reduces stresses on the various components. The floating portion is surrounded on all sides by isolation portions (e.g., made of elastomers or other materials) that are held within a casing that attaches to the body of the UAV. In one implementation, the motor mount assembly is modular such that one or more of the isolation portions may be replaced with different isolation portions (e.g., having different attenuation properties), depending on the direction and nature of the vibrations from the propeller motor that are to be attenuated for a particular application.

Abstract: The disclosure describes an automated aerial vehicle (AAV) and system for automatically detecting a contact or an imminent contact between a propeller of the AAV and an object (e.g., human, pet, or other animal). When a contact or an imminent contact is detected, a safety profile may be executed to reduce or avoid any potential harm to the object and/or the AAV. For example, if a contact with a propeller of the AAV by an object is detected, the rotation of the propeller may be stopped to avoid harming the object. Likewise, an object detection component may be used to detect an object that is nearing a propeller, stop the rotation of the propeller, and/or navigate the AAV away from the detected object.
