Nextarity brings robots to pipe joints, automating manual maintenance in heavy infrastructure

When infrastructure automation is mentioned, attention usually turns to digital monitoring systems or smart sensors, but the startup “Nextarity” chose to address the most tiring and hazardous point in the field: unscrewing and fastening bolts on metal pipe couplings. The company’s founder, Lindsey Elliott, an engineer and former planner at Exxon Mobil, focused on tackling recurring physical problems and work injuries that affect pipe-installation technicians, after years of observing the demanding maintenance reality and productivity loss linked to fatigue in this sector.

The innovation developed by the company, selected for the “Startup Battlefield 200” list at the TechCrunch Disrupt conference, is a battery-powered handheld robot operated remotely. The device consists of two main segments that attach around the metal pipe; the robot travels along the joint path and unscrews or tightens four bolts simultaneously, eliminating the strenuous physical effort workers previously spent for long hours under harsh field conditions.

Precise mechanical automation shifts the direct physical effort burden from technicians’ arms to portable self-controlled systems.The company designed its robot to fit the most common standard pipe sizes, allowing it to be placed inside a rugged Pelican case and carried by a single worker between job sites. Nextarity relies on a construction-equipment rental model rather than selling the units as heavy capital assets, giving contractors rapid field flexibility without upfront purchase costs.

The design idea emerged after specialized discussions Elliott held with maintenance technicians and members of the Pressure Vessels and Piping Division of the American Society of Mechanical Engineers. Field data showed that about eighty percent of pipe networks have diameters between two and eight inches, a standardized range that makes the task an ideal candidate for repeatable automation. Applications of the system extend beyond oil, gas and petrochemicals to include water-treatment plants, food and beverage industries, mines, nuclear facilities, and sustainable manufacturing plants.

Focusing on repetitive tasks with uniform standards shortens the time gap between robot innovation and commercial adoption in large projects.For the energy, industry and water sectors in the Gulf region, this shift carries a direct operational impact. Refining networks, desalination plants and massive petrochemical projects in the area rely on thousands of kilometres of standard-coupled pipelines, which require costly periodic shutdowns for maintenance and bolt-torque verification. Introducing specialized rental-model robots enables operations managers to cut field-downtime, reduce work-related injuries and thermal stress, and boost the efficiency of local maintenance teams without needing to scale up manual labour forces in harsh environments.
