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.

The present invention relates to a device for supplying electrical power to a wired system for a drone (1). The device according to the invention includes at least one power converter (4) on the ground and one power converter (2) at the level of the drone (1), regulation at the level of the converter on the ground ensures that the output voltage of the power converter (4) on the ground increases when the output current of the power converter (4) on the ground increases. The method according to the invention is intended for all wired drones, the wire (3) of which is used to supply electrical power to the drone (1).

A flying toy system capable of independently hovering at a programmable height and respond to the manipulations and/or actions of one or more users through their fingers or similar digit extensions, all while continuing an autonomous flight regime.

A tethering system for a remote-controlled device including a tether line having a first end adapted to be connected to a ground support and a second end adapted to be connected to the remote-controlled device. The system further includes an anchor-point disposed between the first and second ends of the tether line, the anchor point having an eyelet for securing the tether line and allowing the tether line to slide through the eyelet during use. The anchor-point and eyelet enable the tether line to flex or bend and the remote-controlled device to maneuver one or more of over or around the target area without interfering with any nearby obstructions.
