Abstract: Systems and methods are provided for verifying the placement of tows by a robot. One embodiment includes a robot that includes an end effector that lays up tows, actuators that reposition the end effector, a memory storing a Numerical Control (NC) program, and a robot controller that directs the actuators to reposition the end effector based on the NC program, and instructs the end effector to lay up tows based on the NC program. The system also includes a sensor system comprising an imaging device that acquires images of the tows as the tows are laid-up, a measuring device that generates input as tows are laid-up by the end effector, and a sensor controller that receives images from the imaging device and the input from the measuring device, and updates stored data to correlate the images with instructions in the NC program, based on the input.

Abstract: Provided are methods and systems for inspecting surfaces of various components, such as evaluating height deviations on these surfaces. A method involves aggregating inspection data from multiple line scanners into a combined data set. This combined data set represents a portion of the surface that is larger than the field of measurement any one of the scanners. Furthermore, each pair of adjacent scanners operate at different periods of time to avoid interference. Because operating periods are offset, surface portions scanned by the pair of adjacent scanners can overlap without interference. This overlap of the scanned portions ensures that the entire surface is analyzed. The position of scanners relative to the inspection surface may be changed in between the scans and, in some embodiments, even during the scan. This approach allows precise scanning of large surfaces.
