Sky Sweeper Robot Makes Inspecting Power Lines Simple and Inexpensive

Mechanical engineers at the University of California, San Diego invented a robot designed to scoot along utility lines, searching for damage and other problems that require repairs. Made of offtheshelf electronics and plastic parts printed on an inexpensive 3D printer, the SkySweeper prototype could be scaled up for less than 1, 000, making it significantly more economical than the two models of robots currently used to inspect power
