LEROSH at the Hannover Messe 2024

Future Manufacturing ?

Only 1% of the industrial robots installed worldwide in recent years have been used for material processing such as grinding, polishing, etc. (Source: World Robotics 2023 / IFR )
Why is that? Insufficient tools? Lack of data or robot capabilities? Weak user interfaces?

LEROSH is researching solutions to these problems and will be demonstrating two ways of processing more complex geometries on two different robot systems (KUKA and Universal Robots ) at the Hannover Messe.

Five jam-packed days with good discussions, during which it became clear once again: LEROSH has big potential!

In his presentation, Előd Páll will give you an insight into the current state of research.

Cobots LIVE @HWK Berlin

We were part of the interactive exhibition of the Berlin Chamber of Crafts on 24 January 2024: Cobots live in action!

What it was about: How small robots make crafts and small series production more productive.
When: 24 January 2024 from 13:00 – 18:00 (admission from 12:00)
Where: In the Education and Technology Centre of the Berlin Chamber of Crafts, Großer Saal, Mehringdamm 14, 10961 Berlin.

18 live applications will show how craft businesses are incorporating cobots as new tools in the machine shop. Of course, our robotic sanding application was not to be missed. We have already proven that our application is easy to set up and dismantle. This was also an advantage during our trip to Mehringdamm!

The President of the Berlin Chamber of Crafts, Carola Zarth, was also there to find out about the potential of robotic solutions for the skilled trades.

LEROSH Annual Meeting 2023

In December 2023, we welcomed our LEROSH project partners to the annual meeting in Berlin.

Finding a date with all project partners from the skilled crafts and research sectors is always a challenge, but also the basis for a productive exchange.

Thanks to the large number of participants, we were able to discuss the status quo of the project in presentations and workshops. In addition to discussing new robot technology, the programme also included the outlook for the upcoming project phase in 2024.

The conclusion? It’s going to be exciting!

Local Robot Day

On 19.09.2023 the Local Robot Day of the Werner-von-Siemens Centre for Industry and Science took place.

Our research team passed the stress test! On Local Robot Day at the Werner von Siemens Centre, we demonstrated how quickly our test lab can be dismantled and set up. In addition to exciting insights behind the scenes at LEROSH, there were also tried-and-tested examples of robots already helping tradespeople at work.
In his keynote speech at #RobotiXperience, Adrian Sieler from TU Berlin showed the tension between visions of the future and the reality of robotics research.
Gunnar Bloss from werk5 presented the status quo of the project and Bastian König from Interactive Scape presented the live demo.

We look forward to the next opportunities for dialogue!

Segmentation and path planning for robot-assisted surface processing of complex component geometries

Our project partners from the DLR Institute of Robotics and Mechatronics (DLR Robotics and Mechatronics website) have published a first IEEE paper on robot grinding.

Congratulations Stefan Schneyer, Arne Sachtler, Thomas Eiband and Korbinian Nottensteiner!

Brief description

With the method presented, the surfaces of complex component geometries are automatically analysed and segmented according to the type of machinability with a grinding tool. In the second step, a robotic arm moves along automatically generated machining paths at the appropriate angle to the tool.

This allows users to machine complex parts with the robot without any programming effort. Due to the great variability in the contact guidance of tool and component, small areas and cavities can be reached even with relatively large tools.

Panel discussion: Adaptive robotics in industrial production and the skilled trades - HANNOVER MESSE 2023

What is learnability in robotics?

The learning ability of robotic systems is based on the fact that they learn from experience in relation to certain tasks and an appropriate performance measure. This means that the fulfilment of a task improves with experience, measured against a performance measure (cf. Mitchell 1977).

In order to solve a task, robotic systems can use models trained with learning algorithms, for example. The learning algorithm can also be used to continue learning during operation: The systems improve the previously trained models and expand their knowledge base and capabilities. Today, advanced robotic

AI is driving the #automation of robotics in industry and trade. This harbours opportunities for greater sustainability. Because: Learning robots enable energy-efficient process planning, for example, says Jan Seyler (Festo)

Acceptance of the use of robots in the skilled trades has risen sharply in recent years. Now the question arises: How can experienced craftspeople pass on their expertise to robots that are capable of learning, says Gunnar Bloss (werk5 | new craft)

One of the challenges in AI-supported robotics is obtaining reliable training data. This is far more difficult than training language models, for example, says Dorothea Koert (Technical University of Darmstadt)

Internationally, Germany is strongly positioned in #industry and #robotics with good research, innovative SMEs and #start-ups. This ecosystem now needs to be utilised for industry and trade, says Jan-Henning Fabian (ABB)

LEROSH on the road III. From Oberpframmern to Oberpfaffenhofen. December 2022

The last trip to the craft partners takes the development team within sight of the Alps: Schröter Modell- und Formenbau GmbH in Oberpframmern, Bavaria, specializes in prototype construction for automobiles. What looks like the work of machines at first glance turns out to be precision manual work in many cases, especially the grinding in concave molds.

In contrast, the Institute of Robotics and Mechatronics at the German Aerospace Center (DLR) in Oberpfaffenhofen demonstrated the complex work that robotic systems are already capable of performing: from surgical operations to applications in space – and soon grinding!

So the starting signal has been given: The LEROSH developers are now starting to translate their observations into concrete grinding requirements and to develop application solutions for the use of robotics in individual craft production!

LEROSH on the road II. From Chemnitz to Markneukirchen. November 2022

In November, the LEROSH developers travelled on to the halls of the Fraunhofer IWU in Chemnitz and to the music town of Markneukirchen to gain an insight into the craftsmanship of Stefan Kreul’s cello maker.
In addition to working with large, impressive industrial robots, the Fraunhofer IWU focuses on the development of customised automation solutions for the skilled trades, which for LEROSH means sanding. The expertise that a robot needs to learn and master comes from the craft itself – knowledge that has been passed down through generations in some cases. Stefan Kreul and his employees opened their workshop and introduced us to the art of making musical instruments – and showed us the largest playable violin!

LEROSH on the road. From Bremervörde to Rehna. November 2022

The LEROSH project partners visited Strehl GmbH & Co. KG to follow the manufacturing process of a pediatric orthosis step by step. In addition to exciting insights into the handicraft production, the challenge and the necessity of being able to offer the small patients an individually adapted solution became apparent. There was a lively exchange about the optimal use of robots to support this important work and the people behind it.
The second day of the tour took the project partners to the carpentry firm Eigenstetter GmbH, which excels in handcrafted one-offs and restoration work – and at the same time relies on the support of the robot giant KUKA KR 500.

automatica Juni 2022: Aktuelle Schleifwerkzeuge für den Robotereinsatz

Schleifen und Polieren mit Robotern ist bereits Realität, z.B. mit den Schleifaufsätzen der Firmen OnRobot oder FerRobotics. Beide System können die Anpresskraft des Schleifaufsatzes nachregeln. Das OnRobot-System kann auch die Ausrichtung zur Oberfläche über eine Auswertung des Drehmoments nachjustieren. Die gewünschten Bearbeitungspfade/-punkte können vom Anwender bei OnRobot mittels UR-Cap (Universal Robots) und über einfache Eingabeinstrumente oder den Roboter selbst vorgegeben werden.


Kraftgeregelte Oberflächenbearbeitung

FerRobotics bietet als Marktführer eine große Bandbreite an kraftsensitiven Schleifwerkzeugen. Die Bahnplanung muss allerdings vorprogrammiert sein.


Der Fachkräftemangel wird immer spürbarer
