Evolution of LayupRITE

The LayupRITE system has seen several iterations over the various projects where it, and its predecessor Kinect Assisted Intelligent Layup (KAIL)[1]. All versions included three basic components: a projector, a Kinect and a PC to run both. The main difference between KAIL and the original version of LayupRITE was essentially a big hardware upgrade.

KAIL had shown the utility in marrying user tracking and projection to instruct composites layup, but the projector wasn’t bright enough to be used on carbon fibre materials in the expected lighting conditions of a clean room. A brief study was carried out to determine the power of projector required for this, with woven carbon fibre prepreg being the worst-case in terms of projection. Unfortunately, the worst-case is also the most likely use-case for the system.

In addition to a power boost an ultra-short-throw (UST) projector was used to try and mitigate some of the mounting issues with standard projectors. These projectors had to be mounted at a longer distance from the workspace and directly overhead, leading to a more complex gantry-style mounting solution. By using a brighter, UST projector we were able to get around many of the projection issues with the older KAIL setup.
