One-shot Imitation from Mismatched Execution
Human demonstration videos are a powerful way to program robots to do long-horizon manipulation tasks. However, translating these demonstrations into robot executable actions presents significant challenges due to execution mismatches in movement styles and physical capabilities. Existing methods depend either on paired human-robot demonstrations or on visual similarities between the training and test domains. Humans Read more

Sensorless Transformer for Interaction Force Prediction and Estimation
While recent work has shown that generative AI models, like transformers, can be used to predict future interaction forces, given past recorded data, including recorded forces, many platforms lack force sensors or cannot reliably record past forces. To bridge this gap, this thesis aims to augment a transformer model so it can estimate current interaction Read more

High level reasoning layer for a learning-based interaction force controller for autonomous polishing
This thesis proposes to equip an existing low-level predictive interaction force controller – developed for compliant tasks- with a high-level reasoning layer that autonomously manages polishing operations. While the force controller reliably regulates contact forces and nominal trajectories in real time, it lacks environmental context and goal awareness. The research goal is to design and Read more

Vision-based policies for human-robot collaboration
This thesis investigates vision-based policies (e.g., VLAs, diffusion policy, flow matching) for human-robot collaboration. Despite standard collaborative controllers which make only use of the robot and (if available) human states, vision-based policies are trained additionally on images captured during the task execution. This provides the robot with the possibility to embed the perception of the Read more

Active spoke wheel
Develop and simulate an active spoke wheel design that is able to climb stairs and navigate smooth terrains with a high energy efficiency. Inspired on the concept of actuated spokes as proposed in hybrid locomotion platforms such as IMPASS (IMPASS: Intelligent Mobility Platform with Active Spoke System | IEEE Conference Publication | IEEE Xplore) Contacts Read more

Conceptualization of a Reduced-Complex Cable-Based Gravity Compensation System for Space Manipulator On-Ground Tests
Robotics is primed to play a crucial role in future space missions. By performing tasks such as on-orbit servicing, inspection and de-orbiting, space robotics can enable a sustainable use of Earth’s orbits. The DLR’s Compliant Assistance andExploration SpAce Robot (CAESAR) is a light-weight, dexterous robot with seven degrees of freedom designed for on-orbit servicing in Read more

Development of a training simulator for industrial applications
Immersive simulation systems can be used as training systems but also as systems for monitoring user behaviour. Through behaviour mapping, it is possible to develop safety logic and algorithms with which production systems can be improved. In this thesis, a multidirectional treadmill is used to recreate a demo of a work situation suitable for both Read more
