Abstract
Reporters obtained the following quote from the background information supplied by the inventors: “It is sometimes necessary to inspect or monitor the component s of aerial electric power lines. For some power lines, these components are oft en disposed very high above the ground, making them difficult to access. One technique for accessing the remote component involves raising a human technician fr om the ground or having the technician scale a neighbouring structure in proximity to the component. This presents inherent hazards for the technician, and often requires that the power line be shut off.
