Abstract
Methods, systems, and robots for multi-layer prepreg composite sheet layup. The robotic system may include a memory for storing a dataset including start and end point pairs of a mold of a 3D part that defines a layup sequence, a first robot or a first robot arm that is configured to conform a prepreg layer or sheet onto the mold of the 3D part, and a second robot or a second robot arm that is configured to hold or grasp the prepreg layer or sheet above the mold of the 3D part and stretch or relax the prepreg layer or sheet when the first robot or the first robot arm conforms the prepreg layer or sheet onto the mold. The robotic system may also include one or more processors connected to the first robot or the first robot arm and the second robot or the second robot arm.
