1. A mobile wireless power-delivery device (MWPD) comprising:

  • an autonomous mobile vehicle;

    a controller communicatively coupled to the autonomous mobile vehicle and configured to carry out operations including causing the autonomous mobile vehicle to move the MWPD to specified geographic locations;

    a power source including a rechargeable component;

    a transmitter including;

    a transmit-resonator configured to couple power from the power source into a first oscillating field generated by the transmit-resonator resonating at a first resonant frequency, wherein the first oscillating field is at least one of an oscillating electric field or an oscillating magnetic field; and

    a receiver including;

    a receive-resonator configured to resonate at a second resonant frequency in response to coupling to a second oscillating field generated by a power-supply transmitter other than the transmitter of the MWPD, wherein the second oscillating field is at least one of an oscillating electric field or an oscillating magnetic field,wherein the receiver is configured to, in response to the receive-resonator resonating at the second resonant frequency, transfer at least a portion of power of the second oscillating field to the rechargeable component of the power source,and wherein the controller is communicatively coupled to the power source, the transmitter, and the receiver, and the operations carried out by the controller further include;

    (a) causing the MWPD to (i) move, by navigation of the autonomous mobile vehicle, to a first location in sufficient proximity to a remote receiver to cause the remote receiver to couple with the first oscillating field, and (ii) transfer power to the remote receiver via the first oscillating field, and(b) causing the MWPD to (i) move, by navigation of the autonomous mobile vehicle, to a second location in sufficient proximity to the power-supply transmitter to cause the receive-resonator to couple with the second oscillating field, and (ii) receive power from the power-supply transmitter via the second oscillating field.
