Provided is an operation/posture control method of an unmanned aerial robot. More particularly, a position and posture of the unmanned aerial robot may be measured using a first sensor, and sensing information of the wind for charging a battery of the unmanned aerial robot may be measured using a second sensor. A drone based on the sensing information controls a posture of the unmanned aerial robot such that an angle between the unmanned aerial robot and the ground becomes a specific angle to generate power through a rotation of a propeller in the specific angle based on the sensing information, and the battery may be charged through the generated power.

A method for recording at least one measured value, wherein the measured value is recorded by means of at least one measuring drone, and the measuring drone flies into a predefinable position to record the measured value, is held in the predefinable position by a position adjustment or its change in relation to the predefinable position is recorded, records the at least one measured value, and transmits the at least one recorded measured value or at least one value representing said recorded measured value to an evaluation device and/or stores said recorded measured value.

A drone with its own power generating function is introduced. The drone includes a central body, a battery attached to the bottom of the central body, multiple arms extended from the central body radially, drive rotors to be fitted on the top of the arms, a ring-shaped subsidiary guide positioned below the arms and supported by the multiple arms and multiple 1st generators arranged in parallel to the drive rotors on the subsidiary guide

Tethered unmanned aerial vehicle (TUAV) includes at least one wing fixed to a fuselage. The wing is comprised of an airfoil shaped body capable of producing lift in response to a flow of air across a major wing surface, and can include at least one flight control surface, such as an aileron. One or more buoyancy cell is disposed within the fuselage for containing a lighter than air gas to provide positive buoyancy for the TUAV when the TUAV is disposed in air. A tether attachment structure facilitates attachment of the TUAV to a tether which is secured to an attachment point for securing the TUAV to the ground when aloft. A wind-powered generator is integrated with the TUAV and configured to generate electric power in response to the flow of air across the least one wing when the TUAV is aloft.
