Successful School Student Competition PlaNeT

On Saturday, 7 March 2015, SimTech’s student competition PlaNeT SimTech took place for the first time. Due to the motto “solving problems from the natural and technical sciences” (“Probleme lösen aus Naturwissenschaften und Technik”), the Cluster of Excellence SimTech was looking for talented students in their final years of school in Baden-Wurttemberg. The competition was scheduled for a whole day. Beginning at 9 in the morning, equipped with nothing more than notebooks, whiteboards and the knowledge obtained at school, eight teams started to work on the difficult question of the contest. This year’s problem was: “How much energy could be (re-)gained if Stuttgart exploited the airflow in the city’s tunnel system?” The jury was amazed of the unique and clever approaches that the students submitted at the end of the day. The winning team received a check of 500 Euro. Congratulations to Kianusch Vahid Yousefnia and Leonard Bauersfeld from the Hans-Thoma-Gymnasium in Lörrach. The two runner-up teams earned themselves 250 Euro each. Congratulations to Marius Hagmayer, Lukas Fuchs and Tobias Schlechter from the Gymnasium Friedrich II in Lorch, and to Jonathan Brielmaier, Josia Seidel, Sebastian Toksig-Mayer and Markus Vogler from the Dietrich-Bonhoeffer-Gymnasium in Filderstadt-Sielmingen. The competition is entirely sponsored by the Industrial Consotrium SimTech e. V.

After this successful first round, the competion will now take place on a regular basis as an event of the SimTech Junior Academy.

SimTech at the EXPO 2015 in Milan

After their great success at the EXPO 2010 in Shanghai, scientists of the Cluster of Excellence in Simulation Technology (SimTech) take part again in the EXPO 2015 in Milan. This year’s world exhibition is entitled „Feeding the Planet, Energy for Life“. The German Pavilion – presented under the heading “Fields of Ideas” – is designed to involve its visitors. „Be(e) active!“ is the motto. The tour includes a show which has been made possible by scientists of SimTech. Here, the visitors will be able to watch the land- and cityscapes of Germany through the eyes of a flying bee. Two large bee eyes will serve as projection screens and display the bee’s view from above. The two light-weight robots are moved by steel cables and winches. The bee eyes will “fly” above the heads of the visitors and move through the showroom in a “bee-like” manner.

EXPO Show

This sounds simple, but it is very complex from a technical point of view and requires solid scientific know-how. Without simulations, the prototyping of the bee’s eyes would not have been possible. The Cluster of Excellence SimTech which is funded by the German Research Foundation (DFG) not only provides the scientific basis for the development of the light-weight robots (Jun.-Prof. Dr.-Ing. Andreas Pott has chosen this topic for his Habilitation), but it also offers the possibility of networking and cooperation between scientists. Thus, two institutes of the University of Stuttgart have worked together on the exhibit: the Institute of Engineering and Computational Mechanics (ITM) has developed the software by which the movement of the two light-weight robots was described. In particular, the institute’s director, Prof. Dr.-Ing. Prof. E. h. Peter Eberhard, and his coworker, Fabian Schnelle, created the software which determines the eyes’ trajectory in the room. Adding to this, Andreas Pott, expert of light-weight robots, and his coworker, Philipp Tempel, from the Institute for Control Engineering of Machine Tools and Manufacturing Units (IWS) developed the control software.

The robots are fastened onto eight cables each and move and twist through the room. The software transfers the previously defined paths and orientations of the bees’ eyes into movement by giving the command to shorten or stretch the cables. Besides, the speed of the cables needs to be adjustable such that it fits the dramaturgy of the flight. After all, this has been a complex process which required scientific work and engineering from the scientists of SimTech. Prof. Dr.-Ing. Wolfram Ressel, Rector of the University of Stuttgart, is proud of this: “Without the development of the two software programs, the idea of the bees’ eyes could not have been implemented in the show.”

Working on this project has been an extraordinary experience for the SimTech scientists: especially the interplay of design, science and safety has been a great challenge, as emphasised by the director of the ITM Prof. Peter Eberhard: “The translatory motions and tilts of the colossal bees’ eyes with those projection screens underneath above people for a time span of six months required a high reliability and safety of all aspects. Furthermore, the robots shouldn’t look like technical robots in the show and therefore, we had to deal with limitations of mobility and other technical challenges.”

In fact, the question of safety was of major importance to the scientists, because the heavy robots (130 kilograms each) hover above 16.000 people per day. Naturally, for this purpose, the boundary conditions have to be determined sharply. The importance of design and aesthetics in this project was also unusual for the scientists. In the end, the thrilled visitors will perhaps sense that this seemingly light and playful construction rests upon high-level mathematics and complex simulation methods.

Leaving aside the efforts of preparation, the EXPO allows the scientists to present their work to a larger audience than usual. Finally, the scientists who work on the SimTech project “ Improved Modelling of Cables for Kinematics and Dynamics of Leight-weight Robots” can prove to a huge international audience that their long term theoretical research works in practice.

Rainer Helmig is 2015 Darcy Distinguished Lecturer

Professor Dr.-Ing. Rainer Helmig has been appointed Darcy Lecturer 2015. The nomination is an outstanding recognition for Helmig’s work in the field of groundwater research. A highly decorated jury has chosen Helmig as this year’s representative of the renowned lecture series. The Darcy Distinguished Lecture Series in Groundwater Science was founded in 1986 with the aim to increase interest in groundwater science and technology. Darcy Lecturers are asked to give a lecture by scientific institutions all over the world. Thus they are able to reach a broad international audience. Usually, Darcy Lecturers offer more than 50 talks on all five continents of the world. Rainer Helmig presents two different topics from which one can choose:

“Evaluating the Competitive Use of the Subsurface: The Influence of Energy Storage and Production in Groundwater”

and

“Modeling and Analysis of Soil-Moisture Processes in the Subsurface: The Influence of Evaporation and Salt Precipitation in Groundwater”.

Rainer Helmig is member of the Board of Directors at the Stuttgart Research Centre of Simulation Technology (SimTech). Since 2000, he is head of the Department of Hydromechanics and Modelling of Hydrosystems at the Institute for Modelling Hydraulic and Environmental Systems, University of Stuttgart, Germany. His major focus is on numerical modelling of flow and transport processes. Research in this field is relevant to environmental issues as well as technical and biological systems, which need to be explored, for example, when it comes to energy storage in the subsurface.
