Abstract: A first hand control controls an altitude of a vertical takeoff and landing (VTOL) aircraft; the movement of the VTOL aircraft within a plane defined by a roll axis and a pitch axis is independent of the first hand control. The first hand control is provided on a first hand side of a pilot's seat included in the VTOL aircraft. A second hand control controls the movement of the VTOL aircraft within the plane defined by the roll axis and the pitch axis; the altitude of the VTOL aircraft is independent of the second hand control. The second hand control is provided on a second hand side of the pilot's seat that is opposite from the first hand side.

Abstract: Described is an apparatus and method of an aerial vehicle, such as an unmanned aerial vehicle (“UAV”) that can operate in either a vertical takeoff and landing (VTOL) orientation or a horizontal flight orientation. The aerial vehicle includes a plurality of propulsion mechanisms that enable the aerial vehicle to move in any of the six degrees of freedom (surge, sway, heave, pitch, yaw, and roll) when in the VTOL orientation. The aerial vehicle also includes a ring wing that surrounds the propulsion mechanisms and provides lift to the aerial vehicle when the aerial vehicle is operating in the horizontal flight orientation.

Abstract: Systems and methods are provided for multi-orientation flight. An unmanned aerial vehicle (UAV) may be capable of flight in a first orientation and a second orientation that may be different from the first orientation. For example, a UAV may include one or more electronic speed control (ESC) units that may control direction of rotation of one or more propulsion units depending on the orientation of the UAV, to generate lift for the UAV. The one or more propulsion units may include protective covers that may protect one or more rotating components of the propulsion units when the UAV is on a landing surface in the first orientation or the second orientation. The UAV may change orientation on the landing surface or while in flight, in response to a sensed condition and/or instructions from a remote user.

Abstract: Described is an unmanned aerial vehicle (“UAV”) that includes a lifting propulsion mechanism that is circumferentially-driven and includes a propeller assembly and a propeller rim enclosure. The propeller assembly includes a plurality of propeller blades that extend radially and are coupled to an inner side of a substantially circular propeller rim that encompasses the propeller blades. Permanent magnets are coupled to an outer side of the propeller rim. The propeller rim and the magnets are positioned within a cavity of the propeller rim enclosure such that the propeller rim will rotate within the propeller rim enclosure. Also within the cavity of the propeller rim enclosure are electromagnets that are used to cause the propeller rim to rotate.

Abstract: A modular platform is provided and includes a platform having upper and lower surfaces. The modular platform further includes one or more propulsion units, mesh coverings, jack elements and a lock mechanism. The one or more propulsion units are embedded within the platform to generate upward thrust. The mesh coverings overlay each of the one or more propulsion units in the upper surface. The jack elements are coupled to the lower surface and support the platform above an underlying substrate. The lock mechanism connects the platform to a neighboring platform. A power storage unit is embedded in the platform and powers the one or more propulsion units, the jack elements and the lock mechanism. A control unit is embedded in the platform and controls operations of the one or more propulsion units, the jack elements and the lock mechanism.
