  • Patent number: 9753461
    Abstract: An aerial inspection system is provided, including an unmanned aerial vehicle (UAV) having an articulated arm coupled thereto. An end effector is coupled to a second end of the articulated arm, the end effector sized and shaped to extend at least partially around an aerial cable in close proximity. One or more sensors are positioned along an inner surface of the end effector, and provide feedback to a control unit. In response, the control unit adjusts a position of at least one of the UAV, the articulated arm, and the end effector such that the end effector maintains a close, non-contact position with respect to the cable.
