It will be a PEEK or PEKK based thermoplastic resin. I'd bet maybe the stuff in this article. https://www.compositesworld.com/articles/peek-or-pekk-in-future-tpc-aerostructures
As for the robot I think they're doing a narrow tape robotic arm. In a traditional layup you would have sheets of pre-preg that then get cut into the hundreds of small flat forms on a lazer table. These flat pieces are then all hand laid into the mold per the schedule. With the narrow tape the robotic arm would be laying out hundreds of strips in to get to the final schedule. They then might trim the perimeter of the schedule before moving that into the mold. Google Automated Fiber Placement and you get an idea of the tape heads on the end of the robot arms.
