Abstract
USC researchers have developed a hybrid human-robot cell to streamline the labor-intensive multi-layer prepreg composite sheet layup process. Human experts initially assess and provide high-level commands, which the system translates into safe trajectories for the robots. The feasibility of using robotic manipulators and specialized end-effector tools for layup has been experimentally validated, with increased efficiency demonstrated in this technique. Moreover, the hybrid cell ensures process consistency, offering significant benefits for composite manufacturing.
Benefit
- Streamlines prepreg composite sheet layup process
- Combines human expertise with robotic precision
- Reduces manual labor, associated costs, and risks
- Increases process consistency and quality
Market Application
The composites industry is growing quickly, particularly in the aerospace, ground transportation, marine, and clean energy sectors. However, current automated fiber placement methods face limitations in handling complex geometries, resulting in low throughput and defects. A disruptive technology that integrates automation with human precision could significantly improve efficiency, consistency, and cost-effectiveness, creating a lucrative opportunity for composites manufacturing.
