A system includes a first sensor having a fixed location relative to a workspace, a second sensor, at least one robotic manipulator coupled to a manipulation tool, and a control system in communication with the at least one robotic manipulator. The control system is configured to determine a location of a workpiece in the workspace based on first sensor data from the first sensor and a three-dimensional (3D) model corresponding to the workpiece. The control system is configured to map a set of 2D coordinates from a second 2D image from the second sensor to a set of 3D coordinates based on the location, and to generate one or more control signals for the at least one robotic manipulator based on the set of 3D coordinates.

The present embodiment provides a composition containing a rare earth complex and a fluorine-based solvent, which can also be used in a fluorescent flaw inspection method. A rare earth complex-containing composition according to the present embodiment is a rare earth complex-containing composition that contains a rare earth complex containing: a rare earth ion; two or more phosphine oxide ligands having different structures; and a β-diketone ligand, the rare earth complex being dissolved in a fluorine-based solvent. The present embodiment also relates to a fluorescent flaw inspection method using the same.

A system and method for coating marine pipeline weld joints and wet inspection of the applied coating is provided. The coating system includes an anti-corrosion coating including a fluorescent pigment to enhance inspection of the applied coating. The system also includes a robotic crawler for traversing inside the pipe and carrying a coating apparatus and inspection apparatus respectively configured to apply the coating on the weld joints and facilitate inspection of the wet coating. The coating apparatus comprises a spraying nozzle provided on a forward end of the robotic crawler and configured to spray coating onto on the surrounding circumferential pipe surface. The inspection apparatus includes an ultraviolet radiation emitter for activating the fluorescent pigment in the coating and a camera for providing a live image feed of the coated weld joint area to an operator computing station for inspection of the applied coating.

A method, system and devices for optical structural health monitoring that implements digital image correlation (DIC) by applying an invisible pattern comprising a random dot pattern and/or codes, which is applied using a coating containing a dye or substance that is not visible during the normal lighting conditions. The structure is imaged at different time intervals by capturing images of the pattern and codes using a camera and suitable light source. The captured images of the pattern and codes are stored in a CAD file that represents the structure or part to which the pattern and codes are applied, and includes the locations of the pattern and codes. Comparative measurements of the pattern and codes (e.g., using DIC) determine one or more structural health parameters, such as strain, deformation, and other stresses or averse conditions that may be detected from one interval to another (e.g., between measurements).

An easily inspected shaft assembly is provided and includes a shaft, a sleeve receptive of a portion of the shaft and an optically activatable layer including first and second sections disposed on respective exterior surfaces of the shaft and the sleeve, respectively, such that the first and second sections move relative to one another as the shaft and the sleeve move relative to one another.
