LineScout power grid robot rolls on down the line
We've seen prototype cable-crawling robots that look like UFOs from the Electric Power Research Institute, but north of the border rolling robots are already checking live high-voltage power lines in the vast Hydro-Quebec network.
Developed at the Hydro-Quebec Research Institute following the 1998 ice storm, the LineScout is a remote-controlled rolling robot that uses its movable, 360-degree cameras to inspect power lines.
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.
