There are multiple coatings applied to the F-35, and achieving the correct thickness is not always possible with the robotic spray process simply due to the complex contour, which can be rather severe in places, and the paint plume being sprayed. To achieve a target thickness, an operator must measure the thickness at several discreet points, then sand or add material as needed. The manual measurement process requires a stencil to be placed on the aircraft to identify the measurement points, and can be prone to spot sanding, leading to an out-of-tolerance coating. A robotic inspection system was developed to address this problem by robotically scanning the surface of the aircraft with a metrology device, then projecting a visual aid which guides the operator to where sanding or adding material is needed. The system is comprised of a sensor and projector which are attached to a collaborative robotic arm, all of which is mounted on an Autonomous Mobile Robot (AMR). The AMR drives the system into place in front of the desired inspection area. From there, the system scans the surface of the aircraft to measure thicknesses. The results of the inspection are then optically projected onto the surface so the operator can work the coating and rescan zones as needed.
