From video description:

“In this video, we showcase how robots can learn from human experts to master complex task sequencing in various manufacturing processes, such as surface finishing and composite layup. We demonstrate how robots can learn the expert’s task sequencing policies for composite layup task and perform execution on a brand new test part.”
