Machine tightens big pipe bolts without hands-on work

Nexterity has built a battery-powered machine that loosens and tightens bolts holding pipes together, controlled from a distance. Founded by former ExxonMobil engineer Lindsey Elliott, the two-part tool wraps around pipe, slides into place, and works on four bolts at once with no hands on them. It fits common pipe sizes and packs into a Pelican carrying case.
