摘要： An aerial vehicle is described herein. The aerial vehicle includes a lift mechanism that includes a rotor blade assembly coupled to a motor assembly. The rotor blade assembly includes a plurality of rotor blades that are pivotably coupled to a rotor blade clamping mechanism. The rotor blade clamping mechanism includes an upper paddle clamp that is coupled to a lower paddle clamp. The upper paddle clamp includes a center protrusion and a plurality of blade support protrusions extending outwardly from the lower outer surface. The center protrusion includes a center shaft aperture sized and shaped to receive a motor shaft therein. Each blade support protrusion is sized and shaped to be inserted through a corresponding positioning aperture of a corresponding rotor blade. The lower paddle clamp includes a central recess to receive the center protrusion therein and a plurality of blade recesses to receive a corresponding blade support protrusion therein.

摘要： An aerial system, including a processing system, an optical system, an actuation system and a lift mechanism, includes an autonomous photography and/or videography system 70, implemented, at least in part, by the processing system 22, the optical system 26, the actuation system 28 and the lift mechanism 32. The autonomous photograph and/or videography system performs the steps of establishing a desired flight trajectory, detecting a target, controlling the flight of the aerial system as a function of the desired flight trajectory relative to the target using the lift mechanism and controlling the camera to capture pictures and/or video.

摘要： A frame assembly for an aerial system includes a body and first and second rotor assemblies. The first and second rotor assemblies are coupled to the body by respective hinges. The first and second rotor assemblies are movable between a deployed position and a stowed position. Each rotor assembly includes a shaft assembly coupled to the hinge at one end and having a rotor assembly mounted to an opposite end. A rotary actuator is coupled between the rotor assembly and the shaft assembly and is configured to controllably rotate the rotor assembly relative to the shaft assembly.

摘要： A method for controlling an aerial system with a rotor enclosed by a housing, including: operating the rotor in a flight mode, detecting a grab event indicative of the aerial system being grabbed, and automatically operating the rotor in a standby mode. A method for controlling an aerial system including a central axis extending normal to a lateral plane of the aerial system, including: generating a first aerodynamic force with a set of rotors enclosed by a housing, detecting that an acute angle between the central axis and a gravity vector is greater than a threshold angle, and operating each rotor of the set of rotors to cooperatively generate a second aerodynamic force less than the first aerodynamic force with the set of rotors.

摘要： An aerial system includes a body, a propeller coupled to the body, and a motor coupled to the propeller. The motor is configured to rotate the propeller in a first direction, wherein an other portion of the aerial system rotates in an opposing second direction. The other portion of the aerial system that rotation in the opposing second direction may be the body or a second propeller. The aerial system also includes a processing system configured to control the motor to cause the aerial system to hover in a substantially fixed pose, and a camera configured to obtain images of an environment proximate the aerial system while the aerial system is hovering.
