Over the last five years, several research teams around the world have been developing concepts, lab prototypes and control algorithms dedicated to transmission line inspection robots. Most have not progressed to actual field testing, far less use on live lines for inspection or maintenance tasks. One exception is LineScout Technology, developed by Hydro-Québec's research institute. The video presents footage from live-line inspections and work performed by LineScout over the last few years on transmission lines. This paper presents key elements of typical procedures developed over time to prepare for and perform successful live-line robotic work.
