A self-localization method and system to estimate the position of a tethered quadcopter using only the onboard sensors. Embodiments of the invention are based on the dynamics of the tethered quadcopter and the principles of an accelerometer. The estimated orientation angles of the tether were used to estimate the location of the quadcopter with respect to the connecting point of the tether, which can be a ground vehicle. The results generated by both the software simulation and actual experiments reveal the effectiveness and accuracy of embodiments of the present invention.

Certain exemplary embodiments can provide a method, which comprises causing an article to be picked up and delivered via a working drone substantially without human intervention. The working drone is coupled to a support drone via a tether. The working drone is controlled via a wireless communication system that transmits signals from the support drone to the working drone. The wireless communication system constructed to communicate with a box that receives deliveries via the drone.

A flying machine includes a plurality of rotary blades arranged in the front and rear and on the left and right, a plurality of motors configured to respectively rotate the plurality of rotary blades, contact portions located in front of the plurality of rotary blades and configured to contact a wall surface, vertical blades arranged below the plurality of rotary blades and configured so as to be capable of inclining toward a rear side or toward a front side, and so as to be capable of sliding within a range in a direction toward the front side or the rear side in a rotation area of the plurality of rotary blades and driving units configured to incline the vertical blades toward the rear side or front side, and to slide the vertical blade in a direction toward the front side or rear side.

A remotely controlled, tethered vehicle system is comprised of a communication network interface, a system command and control module, a power source, a tether cable spooling apparatus and a remotely controlled vehicle that is tethered to the communication, control and power source by a cable that is controlled to be dispensed from or retracted into the spooling apparatus. The spooling apparatus has a spooling mechanism that is controlled to move the cable into and out of the spooling apparatus without using a slip ring device.

A tethered uni-rotor network of satellite vehicles, is a novel aerial system which combines the best features of both fixed-wing and rotorcraft design methodologies, while minimizing their respective deficiencies. It is made up of a central hub with multiple tethers, where each tether arm radiates outward and attaches to a satellite vehicle; each having lifting airfoil surfaces, stabilizers, control surfaces, fuselages, and propulsion systems. The entire system operates in a state of rotation, which is driven by the propulsion units on each satellite. As the system rotates, centrifugal forces pull the satellite vehicles outward, which maintain tension on the tether arms. As the satellite vehicles move through space, the airfoils generate lift which supports each satellite and a distributed portion of the weight of the central hub.
