Hydro-Québec Research Institute (IREQ) developed and BC Transmission Corporation have developed the new LineScout, a Power Line Inspection Robot. This nifty robot is able to work on the power lines while they are operating (at very high tension). It has posses a vast array of cameras and tools that allow the remote operators to inspect and conduct (albeit minor) repairs on the power lines without needing to put the off-service or risking their lives.
This innovative concept has even won the two institutions an Edison Award. See the video below for further information about the robot operation and features.
