Abstract
A manufacturing system includes: stability targets; a set of rails; robots including photogrammetry targets mounted on heads of the robots, the robots move along the set of rails, and each of the robots including a plasma cutting tool or a camera mounted on one of the heads; and a photogrammetry system. The photogrammetry system includes: a support stand; overhead cameras mounted on the support stand above the robots and a workpiece to be worked on by one of the robots; and a control module. The control module: via the overhead cameras, determines locations of the stability targets and photogrammetry targets; based on the locations of the stability targets and photogrammetry targets, determines locations of the overhead cameras and heads of the robots; and controls the robots to create and inspect a feature on the workpiece based on the locations of the overhead cameras and heads of the robots.
