Unmanned aerial vehicle docking systems and methods are presented herein. A UAV can hover in a hovering position above a docking pad of the UAV docking system based on positioning measurements. An on-board camera can image a machine-readable code present on the docking pad. The hovering position of the UAV above the docking pad can be adjusted based on imaging of the machine-readable code and ranging measurements to the docking pad. A tether can be extended from the UAV towards the docking pad. The hovering position of the UAV and extension of the tether can be adjusted such that a mating device present on a distal end of the tether engages with a coupling device of the UAV docking pad. The tether can be reeled in to the UAV to assist in lowering the UAV from the hovering position to a landing position on the docking pad.

The presently disclosed embodiments generally relate to systems, devices, and methods for sensing and charging of electronic devices using coils. In some embodiments, the presently disclosed system can include a pad, a charging foot, and a backpack. The pad can include one or more nested coils therein that can sense one or more corresponding receiver coils of an unmanned aerial vehicles (UAV) that landed thereon. The nested coils of the pad can provide charging energy to the UAV independent of the location along the pad in which the UAV landed, and no precise alignment between the receiver coils and the charging coils is required. The charging foot can be attached to one or more legs of the UAV, and can include a receiver coil and circuitry to regulate energy received by the coil to a charging voltage level that can be provided to the battery.
