Institute for Mechatronic Systemes in Mechanical Engineering
01.07.2025
Masterthesis
Traditional robotic arms still face challenges in achieving both lightweight and high dynamic precision. Hence, the overall objective is the development of a lightweight robotic arm, to improve operation safety and efficiency. Based on reference robot arm, the student will develop and enhance design with innovative meta-structure, metamaterial, and bio-based composite materials. An optimization analysis, based on a multi-objective design process, will be carried out in view to satisfy structural rigidity, a proper dynamic behavior (natural frequency and vibration dissipation), a lower weight and a green manufacturing process. The thesis will be performed remotely and supervised by UNINA, Naples.
Kinematics analysis and optimisation of drives
Institute for Mechatronic Systemes in Mechanical Engineering
01.07.2025
Masterthesis
At VIAME, we are developing new concepts for lightweight design in several sectors (transportation, energy, machining,…). This research project will focus on detailed analysis drives and their influential design and operating parameters. Various optimisation strategies, including tooth profile modifications and bearing conceptions, should be comprehensively evaluation together with developed lightweight concept. To this end, detailed FEM and dynamic modelling will be achieved. The complexity of modelling will lead to a metamodeling stage, in order to deal with different uncertainty sources. The final goal will be on the minimization of cycloid drive mass and backlash effects while maximizing the transmission efficiency and precision. The thesis will be performed remotely at Ecole Central de Lyon, France.

01.07.2025
Masterthesis
The target of this thesis is to develop lightweight solutions considering 3D printing technologies for high performance-to-cost implementations. Detailed parameters, such as clearance, deformation, accuracy, backlash, stiffness, load capacity of cycloid drives will be discussed during material and topology design. Meanwhile, proper 3D printing settings will be investigated to ensure large contact areas for load transfer and low shear stress. Software-based design methods will be applied in the parameter analysis to efficiently guide gearing design. For this, suitable mathematical modelling strategies and parametric uncertainties will be analyzed in detail. Thesis will be performed remotely with UNINA, Naples.

Structural optimization and sustainable manufacturing of a harmonic drive
Institute for Mechatronic Systemes in Mechanical Engineering
01.07.2025
Masterthesis
The objective of this thesis is to apply new manufacturing techniques to deal with the unique characteristics of the primary component of harmonic drive, i.e. flexspline, for high torsional rigidity and high radial flexibility. More specifically, sustainable manufacturing approaches, such as 3D printing methodologies should combine various green material choices to efficiently reach an optimized shaping of the primary components. With software-based design approach, the student will evaluate the impact of lightweight materials on efficiency, load capacity, costs, safety, and lifetime, while maintaining high precision and compactness.

Development of a system-optimized cruise control for networked vehicles
Institut für Mechatronische Systeme im Maschinenbau

Masterthesis, Bachelorthesis
At the Institute of Mechatronic Systems in Mechanical Engineering, research is being conducted on autonomous, connected robotic vehicles. These vehicles are expected to ensure not only safe but also efficient movement. Current driver assistance systems, such as Adaptive Cruise Control (ACC), are already widely used in modern vehicles and serve as a fundamental basis for future automated driving functions. As part of this thesis, such a system is to be designed for complex urban intersection scenarios, focusing on both safety and efficiency, and implemented into the existing code structure. The approach will then be tested using the traffic simulation platform SUMO.

Scalable Input Device for Dexterous Teleoperation
am Institut für Mechatronische Systeme im Maschinenbau

Advanced Design Project (ADP)
Agile Robots SE is developing a kinematic replica for teleoperation of a humanoid with high DoF hands for data collection used in imitation learning. The current prototype provides two single-trigger handles to signalize grasping commands. This restricts the complexity of the teleoperations and, therefore, the tasks that the humanoid learns through imitation learning. This project aims to develop a multi-trigger handle to capture more nuanced commands.
