| We are developing a teleoperated micro-assembly system. A core component is a force-sensitive micro-gripper. A first gripper prototype has been realized and evaluated. Your task will be to review and improve the current design and to implement automated object slippage detection. - Mechanical and Industrial Engineering, Robotics and Mechatronics

| Cartilage damage in the knee joint can be caused by aging or repetitive actions. It can be treated by surgically removing the damaged cartilage tissue and filling the generated defect with a precisely shaped, healthy cartilage graft. Removing the defected cartilage is commonly done with surgical curettes. We are investigating the use of laser ablation for a more precise defect preparation process. With two different lasers, we managed to obain promising results regarding cell viability in live samples. However, laser parameters such as pulse frequency and energy need to be optimized towards higher cutting efficiency. Your task will be to prepare a setup to test, optimize, and validate various parameter sets using different lasers for articular cartilage ablation. - Biomedical Engineering, Optical Physics

| In the scope of ongoing research, we are developing a soft tissue palpation simulator with a conditional graph neural network (cGNN) model that predicts both surface deformation and reaction force based on the pose of the probing tool. The force prediction is intended to realize haptic force feedback using a human-machine interaction haptic device. The cGNN model takes initial or deformed surface points and a virtual probing tool as input. The current method using a full set of points (1024) can simulate single output in 0.112 s (<10Hz). Using fewer points is possible, which accelerates the simulation time, but some interpolation of points is needed to visualize the surface smoothly. Haptic force feedback devices are typically controlled on kHz clock rates. An interactive soft tissue palpation simulation will require a careful compromise of limitations or interpolation in the spatial and temporal domains. - Engineering and Technology

| The usability of various input mapping methods for controlling a surgical endoscope's motion will be assessed. These methods include joystick-based and head-mounted display (HMD)-based approaches. The project involves building a mock-up endoscope, developing a framework for input acquisition and mapping, and conducting a user study to evaluate performance and comfort in utilizing these methods. - Biomedical Engineering, Mechanical and Industrial Engineering

| We aim to realize a robotic device for in situ printing of biological tissue enabling less invasive treatments. The goal of this thesis project is to develop a tube-based material transfer unit with integrated temperature control for controlling the printing material's temperature during transfer. - Engineering and Technology

| We are developing a teleoperated micro-assembly system to assemble mechatronic prototype devices. Its user interface consists of a number of different devices, including both off-the-shelf and custom input and output devices. Currently, all of these devices have been placed solely based on prior experiences and common best practices and have been fixed provisionally to fit the developers’ needs. Quick adaptation of device positions and orientations would be of great benefit when conducting studies involving a larger number of different users, as the placement of user-side devices has been shown to influence teleoperation performance. Your task would be to define requirements for such an adaptable user console based on the given application, to build a modular console framework, to develop a framework adaptation procedure, and to validate your design in a small proof-of-concept study. - Biomechanical Engineering, Mechanical and Industrial Engineering, Rehabilitation Engineering
