1. An unmanned aerial vehicle (UAV) comprising:

  • an airframe;

    one or more rotors fixed to the airframe;

    one or more motors coupled to the one or more rotors, the one or more motors configured to articulate the one or more rotors at one or more rotor speeds;

    an attitude control system coupled to the one or more motors, the attitude control system configured to determine the one or more rotor speeds;

    at least one tracking component, the at least one tracking component including at least one of(1) a camera configured to capture at least one image associated with a subject, the UAV configured to follow the at least one subject at a predetermined orientation based on the at least one image;

    (2) an image processor configured to generate at least one image stream based on the at least one image; and

    (3) a first transceiver configured to establish a wireless link with a communications device carried by the at least one subject;

    at least one power source having a charge level;

    a power monitor coupled to the at least one power source, the power monitor configured to determine the at least one charge level;

    a power management system coupled to the power monitor and configured to(1) receive the at least one charge level from the power monitor;

    (2) determine whether the at least one charge level is below a first threshold;

    (3) if the at least one charge level is below the first threshold, adjust the distribution of power from the at least one power source to one or more of the attitude control system and the one or more tracking components based on the at least one charge level.
