Path Robotics is a Columbus, Ohio-based company founded in 2016 that develops autonomous robotic welding systems for industrial manufacturing. Its core product line centres on Intelligent Welding Cells powered by Obsidian™, a proprietary AI model trained on tens of millions of welded inches. The cells are designed to see, understand, and adapt to welding tasks in real time, eliminating the need for custom fixtures or dedicated robot programmers. The company reports a first-pass yield of 97% or above for these systems.
The technical domains spanning Path Robotics' work include artificial intelligence, machine learning, computer vision, real-time control and autonomy, and welding automation. The company's target verticals include defence shipyards, data centre construction, utility infrastructure, and broader heavy industry. Its 186,000-square-foot facility in Columbus houses a team of more than 150 engineers, researchers, and operators.
Path Robotics was co-founded by brothers Andy and Alex Lonsberry alongside their father Ken Lonsberry and Matt Klein. Andy and Alex hold PhDs in AI-related fields from Case Western Reserve University. The company traces its origins to a family background in welding and began in a garage before scaling to its current size.
