Jessica Burgner-Kahrs How Can the Characteristics of Continuum Robots Be Optimized for a Specific Medical Application?
University of Hannover (Leibniz Universität Hannover)
In 1831, founded by the scholar Karl Karmarsch, the “Higher Trade School of Hannover” started with only 64 students. Today there are more than 25,000 students in the natural sciences and engineering, the humanities and social sciences as well as in law and economics. In the future, too, studying, teaching and research are to be enjoyable, and therefore one of the declared goals of Leibniz Universität Hannover is to continually improve the quality of teaching and research.

Center of Mechatronics
The interdisciplinary focal point of mechatronics arises from the close cooperation in the fields of mechanical engineering, electrical engineering and computer science. Mechatronics is needed everywhere where an improvement in the overall functionality is to be achieved through the intelligent combination of these individual disciplines. The efficient concentration of the mechatronics activities at the Leibniz Universität Hannover is achieved through the Hannover Centre for Mechatronics (German: Mechantronik-Zentrum Hannover, MZH) which was established in 1999 and is funded by institutes of the Faculties of Electrical Engineering and Computer Science as well as of Mechanical Engineering.

The use of continuum robots – robots that are not composed of rigid links and joints but are continuously bending structures – opens up completely new possibilities for surgery: With this tool surgeons can reach locations in the human body which they would not be able to reach with traditional surgical instruments. This enables them to e.g. remove brain tumors in a minimally invasive way. There are a vast number of parameters to be selected when designing these structures, like diameter, tube thickness, and material. JESSICA BURGNER-KAHRS explains that the ideal combination depends not only on the application but also on patient characteristics. In this video, she describes how the research team tackled the challenge of selecting the right robot design by developing an optimization algorithm that makes use of evolutionary concepts from biology. Testing their simulation results in the laboratory proved that the optimization works well, but also revealed a number of open questions.
