Fraunhofer IWU Develops Hybrid Autonomous Assembly System With Volkswagen Sachsen

On July 8, Fraunhofer IWU revealed progress on the HAutoMont project, developed in collaboration with Volkswagen Sachsen GmbH. The initiative focuses on creating a hybrid-autonomous assembly system that blends manual operations with automated production to install passenger car underbody panels more efficiently while reducing manufacturing costs. In addition to improving current assembly operations, the project is intended to support the development of future production methods and component designs that are better suited for automated manufacturing.

For practical evaluation, the project team selected the aerodynamic underbody shielding panel used on the Germany-built VW ID.3. This lightweight component was chosen because it frequently undergoes modifications throughout the vehicle's lifecycle, making it an effective candidate for studying automation strategies and validating production concepts under evolving design requirements.

The hybrid production solution combines handling robots with automated screw-driving technology to complete the installation process. Vacuum grippers securely position the lightweight polypropylene panel before a robotic system accurately identifies the required mounting locations, inserts the fasteners, and tightens each screw automatically. Because the automated equipment is designed to operate alongside manual workstations, manufacturers can introduce the technology into existing production lines without requiring a fully automated factory environment.

The experience gained through HAutoMont is expected to contribute to both improved manufacturing workflows and future vehicle component development. By evaluating how automated systems interact with evolving part designs, the project partners aim to identify opportunities for greater production efficiency, improved automation compatibility, and lower manufacturing costs across future vehicle programs.

The project is being carried out jointly by Volkswagen Sachsen GmbH, Müller und Pfeiffer GmbH, Stella Systemhaus GmbH, and Fraunhofer IWU, bringing together expertise in vehicle manufacturing, automation technologies, and industrial engineering to advance next-generation hybrid assembly solutions.

Frequently Asked Questions

What is the HAutoMont project developed by Fraunhofer IWU and Volkswagen Sachsen?
The HAutoMont project is a collaborative initiative that combines manual production with robotic automation to improve passenger car underbody panel installation. Using handling and screw-driving robots, the system automates key assembly tasks while remaining compatible with largely manual production lines. The project also studies how future vehicle components can be designed for improved automation, helping manufacturers enhance production efficiency, reduce costs, and simplify the integration of automated technologies into existing manufacturing facilities.
