Hydro-Quebec and BCTC have developed an awesome power line inspection robot that can transverse energized high voltage power lines and perform inspections and even some minor repairs. It is capable of moving past obstacles, keeping track of locations with a GPS unit, and transmitting multiple video feeds (including infra-red) to ground based operators. Although not as sexy as those high flying power line cowboys deployed form helicopters, this sounds like a fantastically practical idea. Watch the video below for a bit more information, though I sure wish it had more robot details and less talking heads.
