AI robot solution for logistics center

In Künzelsau, at the headquarters of the Würth Group, there are final packaging stations in the logistics center, where a wide variety of products arrive in trays on so-called sorter conveyors. Employees remove the objects from the trays and pack them into shipping cartons. Würth has around 1,000,000 products in its portfolio - from small and light products to very heavy parts. Working with heavy parts is extremely stressful for the employees. The "GripperAI" software from Festo should therefore be able to handle parts weighing up to 20 kg with a robot. Festo impressed with its AI expertise and was selected by Würth for the innovation project to develop a customized and flexible solution.

Customized software solution developed

The Advanced Development Analytics and Control department from Festo's Research and Development division worked on the project for over two years: "We built a copy of Würth's sorter conveyors in our laboratory and were thus able to develop the robot's various capabilities: Object-dependent gripper selection, gripping any objects from the trays, packing shipping cartons and handling the cartons and trays," says Jan Seyler, Head of Advanced Development Analytics and Control. The robot cell is equipped with a tool station as a special feature. The robot can use various suction cups and grippers here - depending on the type of object, shape and surface finish, GripperAI determines which tool is most suitable. An integrated camera in the robot recognizes the various objects, enabling precise selection. The Festo GripperAI solution can grip almost anything that is presented to it - and for which the gripper and robot are designed. The grippers specially developed for this project set new standards in robot technology, while the suction cups come from Festo's portfolio.

The customized AI robot solution enables Würth to handle heavy parts and various objects efficiently, which significantly reduces the workload for employees and increases efficiency in operations. "Another advantage of the Festo solution is that it requires no teaching or training. Just do it, just get started. It also works with any robot and vision system, making us flexible in our choice of partners," says Roland Schneider, Head of the Technical Department at Würth.

Development of an educational trail

As part of the partnership, the Festo team was able to test and validate its AI capabilities from research. "Our many years of experience in the fields of mechanics, logistics and industrial automation, as well as our AI expertise as a team, have enabled us to develop this complete solution for Würth," says Jan Seyler. At the same time, a training path is also to be developed to further train the specialists for the future world of work and explain how they work together with the collaborative robot.

Successful deployment

The robot cell has been in operation at Würth since spring 2023 and can serve all the intended lanes. Further development work and optimization steps have already been defined, such as higher speed, better packing and optimization of the overall process. Johannes Scheuermann, Head of Inventory Management at Würth: "We were impressed by the team spirit and the high level of expertise of the developers and researchers at Festo. We are convinced that this project will enable us to significantly improve our logistics processes and facilitate further growth, even in difficult times when there is a shortage of skilled workers." The collaborative robot makes it possible to absorb further growth and support the employees.
