AI-driven autonomous welding workcells for high-mix, low-volume production environments. The AW-3 handles parts up to 60 feet long; the AF-1 targets smaller weldments. Both systems use real-time 3D machine vision to detect part variation and generate weld paths without pre-programming, eliminating the skilled-programmer bottleneck. Deployed in aerospace, shipbuilding, heavy equipment, and defense programs, with bookings surpassing $100M in 2025.
Purpose-built foundational AI model for welding, trained on tens of millions of welded inches across diverse alloys, joint configurations, and weld processes. Obsidian powers real-time path planning, parameter selection, and quality prediction inside Path Robotics' welding cells. Announced in 2025 as the first welding-specific physical-AI foundation model; enables rapid transfer to new part families without robot re-programming.
Mobile autonomous welding robot combining the Obsidian AI model with a quadruped platform, launched April 2026. Brings intelligent welding to large, fixed structures—ship hulls, pressure vessels, infrastructure steel—where the workpiece cannot be moved to a fixed workcell. Extends Path Robotics' physical-AI approach from factory floors to field and shipyard environments.
