On April 16, Path Robotics launched Rove — a quadruped robot with a welding head on top, running the company’s Obsidian Physical AI model. Four days later, Huntington Ingalls Industries (biggest U.S. shipbuilder, the one that builds aircraft carriers and submarines) named it the centerpiece of HYPR, a new line stitching welding, material handling, surface finishing, and inspection into a single automated flow. Live demo running now at Sea-Air-Space 2026 in National Harbor, April 19–22.
Why a quadruped, not a fixed arm
Shipyards have a problem stationary robots can’t solve: the parts are too big to move. Hull sections, bulkheads, massive sheet-metal assemblies — the welder has to walk to the seam. Rove walks. Obsidian lets it look at a complex joint and figure out the weld path itself, no human programmer in the loop. Same trick should travel to construction sites and bridge fab shops.
The API layer
Obsidian exposes a developer interface that lets external MES, WMS, and shipyard PLM systems push welding tasks down and pull QA results back up. HYPR uses that hook to chain Rove with GrayMatter’s vision-based grinding robots into one pipeline. An agent can read a BOM, generate weld tasks, and dispatch them straight to the dog. Commercialization targeted for 2027. Early-customer signups open now.
