# Alex Lonsberry

> Alex Lonsberry is the co-founder and chief technology officer of Path Robotics, the Columbus company applying computer vision, machine learning and purpose-built sensing to variable welding work. Raised around his father's Ohio workshop, trained in mechanical engineering and neural-control research at Case Western Reserve University, Lonsberry helped turn an early customer problem - welding reflective, imperfect parts without rigid programming - into an adaptive robotics platform.

- **Role:** Co-founder and Chief Technology Officer at Path Robotics
- **Organizations:** Path Robotics, Case Western Reserve University
- **Nationality:** American
- **Education:** B.S. in Mechanical Engineering, Case Western Reserve University, M.S. in Mechanical Engineering, Case Western Reserve University, Doctoral studies in Mechanical Engineering; work reported on hold, Case Western Reserve University
- **Known for:** Co-founded Path Robotics and helped architect its AI, sensing and hardware platforms., Helped translate imaging-guided mechanical-systems and neural-control research into adaptive industrial robotics., Built early prototypes at Case Western Reserve University's Sears think[box], which he called Path's incubator and launchpad.

## Career timeline

- **Childhood** — Grew up in Ohio building, machining and welding with his father Ken and brother Andy.
- **2009** — Earned a bachelor's degree in mechanical engineering from Case Western Reserve University.
- **2012** — Earned a master's degree in mechanical engineering; his imaging-guided mechanical-systems research later informed Path's technology.
- **2012-2018** — Pursued doctoral research involving recurrent neural networks, nonlinear dynamical systems, event prediction and biologically inspired robotics.
- **2018** — Co-founded Path Robotics with Andy Lonsberry, Matt Klein and Ken Lonsberry after early prototyping at Case Western Reserve's think[box].
- **2019** — Path Robotics moved to Columbus, Ohio, placing the company near manufacturers and engineering talent.
- **2021** — Path raised a $56 million round as it expanded its adaptive robotic welding platform.
- **2024** — Path closed a $100 million Series D financing round.
- **2025** — Path introduced Obsidian, a purpose-built foundational AI model for welding trained on tens of millions of welded inches.
- **2026** — Path launched Rove, a mobile welding system pairing Obsidian with a legged robotic platform, and expanded into shipbuilding collaborations.

## Achievements

- Co-founded Path Robotics and helped architect its AI, sensing and hardware platforms.
- Helped translate imaging-guided mechanical-systems and neural-control research into adaptive industrial robotics.
- Built early prototypes at Case Western Reserve University's Sears think[box], which he called Path's incubator and launchpad.
- Helped develop an original sensing approach after reflective stainless steel defeated the team's initial off-the-shelf 3D scanning plan.
- Helped grow Path from a university-area prototype effort into a Columbus manufacturing technology company with about 200 employees reported in 2026.
- As CTO, oversees technology that expanded from fixed intelligent welding cells to a mobile platform for shipbuilding and large-scale fabrication.

## Latest updates

- **2026-08** — Path Robotics and GrayMatter Robotics entered performance-based production agreements with HII worth up to $900 million collectively, including a commitment of up to $600 million for Path systems, to expand U.S. shipbuilding capacity.
- **2026-04** — Path launched Rove, a mobile robotic welding system that pairs its Obsidian model with a quadruped platform for shipbuilding, construction and large-format fabrication.
- **2026-02** — Saronic announced a collaboration to integrate Path's physical-AI welding systems into its Franklin, Louisiana shipyard.
- **2026-01** — Path reported that 2025 bookings for its AI welding automation solutions had surpassed $100 million.
- **2025-09** — Path introduced Obsidian, its purpose-built foundational AI model for welding, trained on tens of millions of welded inches.
