We've seen prototype cable-crawling robots Hydro-Quebec network.from the Electric Power Research Institute, but north of the border rolling robots are already checking live high-voltage power lines in the vast
A thermo-infrared imager on the device helps identify power problems, and sensors check the electrical resistance of splices. It's also equipped with manipulators that can unscrew bolted assemblies and perform minor repairs on the line.
Operated with two remote joysticks, LineScout can maneuver around line obstacles such as splices and warning markers for aircraft, while pinpointing trouble spots with GPS for technicians to check. It can roll along lines while they're energized, reducing downtime for the utility.
The bot has been in use on Hydro-Quebec and BC Hydro lines since 2006 and is being used to check lines in places like Indian Arm, British Columbia. In June, it earned Hydro-Quebec and partner British Columbia Transmission an Edison Award from the Edison Electric Institute, which represents about 70 percent of the U.S. power industry.
