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...
A shared dedication to safety, transmission reliability, and the use of innovative technologies to improve business practices brought together Hydro-Québec and British Columbia Transmission Corporation (BCTC) in the field deployment and enhancement of a high-performance power line inspection robot. Since 2003, Hydro-Québec's research institute (IREQ) has been developing LineScout Technology (LST),...
Power line inspection and maintenance is a slowly but surely emerging field for robotics. This paper describes the control scheme implemented in LineScout technology, one of the first teleoperated obstacle crossing systems that has progressed to the stage of actually performing very-high-voltage power line jobs. Following a brief overview of the hardware and software architecture, key challenges associated...
Power line inspection and maintenance practices are evolving as changing market regulations, significantly increased line loading and system availability requirements put pressure on grid owners to innovate. Robotics is thus making its debut in that field. Described in previous papers as an inspection tool, Hydro-Quebec LineScout technology is evolving into a teleoperated mobile robot capable of performing...
Power line inspection and maintenance are fields of application where robotics has yet to be introduced. However, as in many other hostile environments, substantial benefits in terms of workers safety and quality of inspection results could arise. This paper describes one of the latest initiatives toward that goal by presenting the design of a teleoperated robot called the "LineScout". This...
We report three cases of severe community-acquired Legionella pneumophila with acute pancreatitis. Pancreas involvement is unusual. The clinical presentations consisted of painless pancreatitis with only elevation of serum pancreatic enzymes (case 1), tender abdomen with edematous pancreas on computed tomography scan (case 2) and necrosis (case 3). We discuss the possible mechanisms of L. pneumophila...
