We offer these current topics directly for Bachelor and Master students at TU Darmstadt. Note that we cannot provide funding for any of these theses projects.
We highly recommend that you do either our robotics and machine learning lectures (Robot Learning, Statistical Machine Learning) or our colleagues (Grundlagen der Robotik, Probabilistic Graphical Models and/or Deep Learning). Even more important to us is that you take both Robot Learning: Integrated Project, Part 1 (Literature Review and Simulation Studies) and Part 2 (Evaluation and Submission to a Conference) before doing a thesis with us.
In addition, we are usually happy to devise new topics on request to suit the abilities of excellent students. Please DIRECTLY contact the thesis advisor if you are interested in one of these topics. When you contact the advisor, it would be nice if you could mention (1) WHY you are interested in the topic (dreams, parts of the problem, etc.), and (2) WHAT makes you special for the projects (e.g., class work, project experience, special programming or math skills, prior work, etc.). Supplementary materials (CV, grades, etc.) are highly appreciated. Of course, such materials are not mandatory, but they help the advisor to see whether the topic is too easy, just about right or too hard for you.
FOR FB16+FB18 STUDENTS: Students from other departments at TU Darmstadt (e.g., ME, EE, IST), you need an additional formal supervisor who officially issues the topic. Please do not try to arrange your home dept advisor by yourself but let the supervisor get in touch with that person instead!
Causal inference of human behavior dynamics for physical Human-Robot Interactions
Scope: Master Thesis
Advisor: Georgia Chalvatzaki
Topic: In this thesis, we will study and develop ways of approximating an efficient behavior model of a human in close interaction with a robot. We will research the extension of our prior work on the graph-based representation of the human into a method that leverages multiple attention mechanisms to encode relative dynamics in the human body. Inspired by methods in causal discovery, we will treat the motion prediction problem as such. In essence, the need for a differentiable and accurate human motion model is essential for efficient tracking and optimization of HRI dynamics. You will test your method in the context of motion prediction, especially for HRI tasks like human-robot handovers, and you could demonstrate your results in a real-world experiment

Discovering neural parts in objects with invertible NNs for robot grasping
Scope: Master Thesis
Advisor: Georgia Chalvatzaki, Despoina Paschalidou
In this thesis, we will investigate the use of 3D primitive representations in objects using Invertible Neural Networks (INNs). Through INNs we can learn the implicit surface function of the objects and their mesh. Apart from extracting the object’s shape, we can parse the object into semantically interpretable parts. In our work our main focus will be to segment the parts in objects that are semantically related to object affordances. Moreover, the implicit representation of the primitive can allow us to compute directly the grasp configuration of the object, allowing grasp planning. Interested students are expected to have experience with Computer Vision and Deep Learning, but also know how to program in Python using DL libraries like PyTorch.
The thesis will be co-supervised by Despoina Paschalidou (Ph.D. candidate at the Max Planck Institute for Intelligent Systems and the Max Planck ETH Center for Learning Systems).

Cross-platform Benchmark of Robot Grasp Planning
Scope: Master Thesis
Advisor: Georgia Chalvatzaki, Daniel Leidner
Grasp planning is one of the most challenging tasks in robot manipulation. Apart from perception ambiguity, the grasp robustness and the successful execution rely heavily on the dynamics of the robotic hands. The student is expected to research and develop benchmarking environments and evaluation metrics for grasp planning. The development in simulation environments as ISAAC Sim and Gazebo will allow us to integrate and evaluate different robotic hands for grasping a variety of everyday objects. We will evaluate grasp performance using different metrics (e.g., object-category-wise, affordance-wise, etc.), and finally, test the sim2real gap when transferring such approaches from popular simulators to real robots. The student will have the chance to work with different robotic hands (Justin hand, PAL TIAGo hands, Robotiq gripper, Panda gripper, etc.) and is expected to transfer the results to at least two robots (Rollin’ Justin at DLR and TIAGo++ at TU Darmstadt). The results of this thesis are intended to be made public (both the data and the benchmarking framework) for the benefit of the robotics community. As this thesis is offered in collaboration with the DLR institute of Robotics and Mechatronics in Oberpfaffenhofen near Munich, the student is expected to work in DLR for a period of 8-months for the thesis. On-site work at the premises of DLR can be expected but not guaranteed due to COVID-19 restrictions. A large part of the project can be carried out remotely.
