This invention is directed toward an aerodynamically designed drone with a unique angle of propulsion. The drone uses airfoil design to move more efficiently through the air, and the aerodynamic design is optimized when the drone is tilted forward at various degrees of tilt to provide the most aerodynamic profile to the oncoming air. The invention contemplates single hull, double hull and triple hull designs, and is applicable to heaving lifting drones, drones use for photography and remote sensing, and racing drones.

A quadrotor UAV including ruggedized, integral-battery, load-bearing body, two arms on the load-bearing body, each arm having two rotors, a control module mounted on the load-bearing body, a payload module mounted on the control module, and skids configured as landing gear. The two arms are replaceable with arms having wheels for ground vehicle use, with arms having floats and props for water-surface use, and with arms having pitch-controlled props for underwater use. The control module is configured to operate as an unmanned aerial vehicle, an unmanned ground vehicle, an unmanned (water) surface vehicle, and an unmanned underwater vehicle, depending on the type of arms that are attached.

Systems and methods for pre-flight fabrication and/or assembly of various configurations of aerial vehicles are described. Operations of various configurations of aerial vehicles may be analyzed using models based on various inputs, which inputs may be related to routes, environments, vehicles, components, or other factors. A particular configuration may be selected for a selected route and associated task based at least in part on a desired optimization parameter. Then, the particular configuration of the aerial vehicle may be fabricated and/or assembled to complete the associated task via the selected route.

A remotely controlled multirotor aircraft for acquiring images and an interface device for controlling the aircraft, wherein the aircraft includes a receiving component adapted to receive a direction and/or orientation signal which can be transmitted by an interface device, wherein the direction and/or orientation signal defines a direction in which the aircraft must move and/or be oriented, and a flight control component adapted to control the attitude of the aircraft and configured for reading the direction and/or orientation signal, determining, on the basis of the direction and/or orientation signal, the direction in which the aircraft must move and/or be oriented, and generating a control signal adapted to make the aircraft take an attitude such as to make it move and/or be oriented in the predetermined direction.
