Vehicle attitude control using jet paddles and/or movable mass
Attitude and/or attitude rate of a vehicle may be controlled using jet paddles and/or movable masses. Thrust direction generally may also be controlled using jet paddles. The jet paddles may be moved into and/or sufficiently close to the exhaust flow, and out of the exhaust flow, to change the thrust direction. Movable masses may also be used in addition to, or in lieu of, jet paddles. Movement of the movable masses alters a center-of-mass of the vehicle, generating torque that changes vehicle attitude.

SELF-RIGHTING AERONAUTICAL VEHICLE AND METHOD OF USE
A self-righting aeronautical vehicle comprising a hollowed frame and a lift mechanism. The exterior of the frame and center of gravity are adapted to self-right the vehicle. The frame can include sealed, hollowed sections for use in bodies of water. The frame can be spherical in shape enabling inspection of internal surface of partially or fully enclosed structures. Inspection equipment can be integrated into the vehicle and acquired data can be stored or wireles sly communicated to a server. A controlled or other mass can be pivotally assembled to a pivot axle spanning across the interior of the frame. The pivot axis can rotate about a vertical axis (an axis perpendicular to the elongated axis). The propulsion mechanisms can be adapted for use as a terrestrial vehicle when enclosed in a sealed spherical shell.

Systems and methods for maneuvering a package following in-flight release from an unmanned aerial vehicle (UAV)
A package delivery system can be implemented to forcefully propel a package from an unmanned aerial vehicle (UAV), while the UAV is in motion. The UAV can apply a force onto the package that alters its descent trajectory from a parabolic path to a vertical descent path. The package delivery system can apply the force onto the package in a number of different ways. For example, pneumatic actuators, electromagnets, spring coils, and parachutes can generate the force that establishes the vertical descent path of the package. Further, the package delivery system can also monitor the package during its vertical descent. The package can be equipped with one or more control surfaces. Instructions can be transmitted from the UAV via an RF module that cause the one or more controls surfaces to alter the vertical descent path of the package to avoid obstructions or to regain a stable orientation.
Systems and methods for controlling rotorcraft external loads
A method of determining cable angle includes acquiring image data of a cable and a load coupled to a rotorcraft using three-dimensional (3D) spatial perception system, constructing an image of the cable and load using the image data, and determining the angle of the cable relative to the external load at an interface of the cable and external load based on the image.

TETHER COMPENSATED AIRBORNE DELIVERY
A tether compensated unmanned aerial vehicle (UAV) is described. In one embodiment, the UAV includes a winch with a tether to lower an item from the UAV for delivery, a tether compensation mechanism configured to contact the tether as it extends from the winch, and a flight controller to control a flight path of the UAV. The flight controller is also configured to direct the tether compensation mechanism to clamp the tether based on the flight path of the UAV. Further, based on movement identified in the tether using a sensor, a tether response controller can determine a complementary response and direct the tether compensation mechanism to brace the tether against the movement. Thus, the tether compensation mechanism can help stabilize sway or movement in the tether, which can help prevent the tether from undesirable swinging.
AUTOMATICALLY STABILIZED AERIAL PLATFORM FOR CARRYING LIQUIDS
The present application is at least directed to an automatically stabilized aerial platform. The platform includes one or more containers including one or more liquids. The platform also includes one or more sensors coupled to the one or more liquids. The platform also includes one or more flight controllers operatively coupled to the one or more sensors. The flight controllers are configured to automatically adjust flight control elements in real-time to compensate for sensor values indicating sloshing of the one or more liquids beyond a specified limit. The instant application is also directed to a method of automatic real-time stabilization of an aerial platform carrying at least one liquid.
