App zur Generierung von Ernährungsempfehlungen (BA Thesis)

Dies ist ein Wissensrepräsentations-Thema. Basierend auf einem bestehenden Wissensgraphen mit Produktinformationen sollen weitere ernährungsspezifische Informationen wie z.B. Substitute für Rezeptzutaten oder Rezepte für spezielle Ernährungsgewohnheiten generiert werden. Diese Informationen müssen aus bestehenden web-Quellen extrahiert und mit dem Wissensgraphen verknüpft werden. Die Informationen sollen dann in einer Smartphone-App (Android) visualisiert werden. Dabei kann auf bestehenden Apps aufgebaut werden.


  • Arbeit mit Wissensrepräsentation und Wissensgraphen
  • Wissensakquisition aus web-Quellen
  • App Entwicklung mit der Unity game engine und/oder Flutter

Situational awareness in kitchen environments (MA Thesis)

This is a knowledge representation topic including knowledge graphs. The idea is so link external Web-knowledge to an existing knowledge framework in order to include situational awareness so that a robot acting in a household environment can infer what an object is used for in a given situation.

A result would be that a spoon next to a bowl with cereal would be used for eating while a spoon on a stove next to a pot would be used for stirring.


  • Work with KnowRob knowledge processing framework
  • Work with knowledge graphs and Linked Data to create a situational awareness knowledge graph that can be linked to KnowRob
  • Implement reasoning about situations (based on perceived environment) and object use

Integration of novel objects into Digital Twin Knowledge Bases (MA Thesis)

In this thesis, the goal is to make a robotic system learn new objects automatically. The system should be able to generate the necessary models required for re-detecting it again and also consult online information sources to automatically acquire knowledge about it.

The focus of the thesis would be two-fold:

  • Develop methods to automatically infer the object class of new objects. This would include perceiving it with state of the art sensors, constructing a 3d model of it and then infer the object class from online information sources.
  • In the second step the system should also infer factual knowledge about the object from the internet and assert it into a robotic knowledgebase. Such knowledge could for example include the category of this product, typical object properties like its weight or typical location and much more.


  • Knowledge about sensor data processing
  • Interest in model construction from sensory data
  • Work with KnowRob knowledge processing framework

Game Engine Developer and 3D-Modelling (Hiwi Job)

A recent development in the field of AI is the usage of photorealistic simulations, for example to create Digital Twins of environments like households or factories. In our research group, we focus on the development of modern robots that can make use of the potential of game engines. This requires a high degree of specialized game engine plugins that can simulate certain aspects of our research. Another important task is the creation of 3d models.

Therefore, we are currently offering multiple Hiwi positions / student jobs for the following tasks:

  • Modelling of objects for the use in Unreal Engine 4.
  • Creation of specific simulation aspects in Unreal Engine 4. For example the development of interactable objects.


  • Knowledge of 3D-Modelling tools. Blender would be highly preferred.
  • Experience in Game Engine development. Ideally Unreal Engine 4 and C++.

The spoken language in this job is german or english, based on your preference.
