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： 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： Disclosed herein are methods for a multiple degree-of-freedom (DOF) motor system with reduced number of electromagnet control phases. The motor system includes a first body that is able to move relative to a second body along multiple DOFs. The first body has at least one magnetic positioner attached. The second body has a plurality of controlled electromagnets. Control signals, the total number of phases of which is less than half the total number of electromagnets, energize at least one of the controlled electromagnets to create magnetic interaction with at least one magnetic positioner on the first body, and to control the movement of the first body relative to the second body along designated dimension(s).

摘要： An aerial device includes a body, an optical system having gimbal supporting a camera, a lift mechanism coupled to the body, a haptic sensor coupled to the body and configured to generate haptic data, and a processing system disposed in the body and in data communication with the haptic sensor. The processing system is configured to process the haptic data to understand an intended position of the aerial device and/or an intended orientation of the gimbal and convert the intended position to a target position of the aerial device and/or the intended orientation to a target orientation of the gimbal utilizing said processed data irrespective of an initial position of said aerial device and an initial orientation of said gimbal. Also disclosed is a method for controlling the aerial device.
