Abstract

Methods, systems, and robots for multi-layer prepreg composite sheet layup. The method includes obtaining a dataset including start and end point pairs of a mold of the 3D part. The method includes generating a layup sequence based on the dataset and generating multiple trajectories for one or more movements of the first robot or the first robot arm based on the layup sequence. The method includes causing a second robot or a second robot art to hold or grasp the prepreg layer or sheet a threshold distance above the mold or the 3D part. The method includes causing the first robot or the first robot arm to place or conform the prepreg layer or sheet to the mold of the 3D part.
