Abstract
Systems and methods for enabling infinite wireless charging of unmanned aerial systems (UASs) are provided. A UAS detects sources of power and wirelessly charges itself by collecting ambient electromagnetic energy from a power infrastructure. A UAS in accordance with features and aspects described herein is autonomous, may always be wirelessly charged (e.g., with high induced voltage), and can make use of weak energy. Moreover, various charging techniques can be used, such as in-flight, trickle, perching, and/or parking. Dynamic flight is supported using multi-angle MIMO coils. Additionally or alternatively, faster charging can be achieved with a supercapacitor and slower charging can be achieved with a battery.
