Robot offers safer, more efficient way to inspect power lines

A robot invented by researchers in the University of Georgia College of Engineering could change the way power lines are inspected--providing a safer and most cost-effective alternative. Currently, line crews have to suit up in protective clothing, employ elaborate safety procedures and sometimes completely shut off the power before inspecting a power line. It can be difficult, time-consuming and often dangerous work. A team led by Javad Mohammadpour, an assistant professor of electrical engineering, has designed, prototyped and tested a robot that can glide along electrical distribution lines, searching for problems or performing routine maintenance. Distribution lines carry electricity from substations to homes, businesses and other end users.
