Sneha Saha, Leandro L. Minku, Xin Yao, Bernhard Sendhoff, Stefan Menzel , "Exploiting 3D Variational Autoencoders For Interactive Vehicle Design ", 17th International Design Conference (Design 2022), 2022.
AbstractIn automotive digital development, 3D prototype creation is a team effort of designers and engineers, each contributing with creative ideas and technical design evaluations through means of computer simulations. To support the team in the 3D design ideation and exploration task, we propose an interactive 3D cooperative design system for assisted design explorations and faster performance estimations. We utilize the advantage of geometric deep lea...

Satchit Ramnath, Jami J. Shah, Patricia Wollstadt, Mariusz Bujny, Stefan Menzel, Duane Detwiler , "OSU-Honda automobile hood dataset (CarHoods10k)", Dryad.org, 2022.
AbstractThe CarHoods10k data set comprises a set of over 10,000 3D mesh geometries for variants of car hood frames, generated through an automated, industry-grade Computer Aided Design (CAD) workflow described in Ramnath (2019). The data set provides realistic designs that were validated by experts with respect to realism, manufacturability, variability, and performance. Variations in geometries were generated by a feature-based approach that varies para...

Jihong Zhu, Michael Gienger, Jens Kober , "Learning Task-Parameterized Skills from Few Demonstrations", ICRA / RA-L, 2022.
AbstractThis is a follow-up of pub-4739 Moving away from repetitive tasks, robots nowadays demand versatile skills that adapt to different situations. Task- parameterized approaches improve the generalization of motion policy by encoding relevant contextual information in the task parameters, hence enabling flexible task executions. However, training such a policy often requires collecting multiple demon- strations in different situations. To cr...

Sander van Rijn, Sebastian Schmitt, Matthijs van Leeuwen, Thomas Bäck , "Finding Efficient Trade-offs in Multi-Fidelity Response Surface Modeling ", Engineering optimization, 2022.
AbstractIn the context of optimization approaches to engineering applications, time-consuming simulations are often utilized which can be configured to deliver solu- tions for various levels of accuracy, commonly referred to as different fidelity levels. It is common practice to train hierarchical surrogate models on the objective functions in order to speed-up the optimization process. These operate under the assumption that there is a correla- ...

Hemant Kumar Singh, Tapabrata Ray, Mohammad Juel Rana, Steffen Limmer, Tobias Rodemann, Markus Olhofer , "Investigating the Use of Linear Programming and Evolutionary Algorithms for Multi-objective Electric Vehicle Charging Problem", IEEE Access, vol. 10, pp. 115322-115337, 2022.
AbstractWith the increasing uptake of electric vehicles (EVs), the need for efficient scheduling of EV charging is increasingly becoming important. A charging station operator needs to identify charging/discharging power of the client EVs over a time horizon while considering multiple objectives, such as operating costs and the peak power drawn from the grid. Evolutionary algorithms (EAs) are a popular choice when faced with problems involving multiple o...

AbstractDeformable object manipulation (DOM) is an emerging research problem in robotics. The ability to manipulate deformable objects endows robots with higher autonomy and promises new applications in the industrial, services, and healthcare sectors. However, compared to rigid object manipulation, the manipulation of deformable objects is considerably more complex, and is still an open research problem. Addressing DOM challenges demands breakthroughs i...

Thiago de Jesus de Araujo Rios , "Learning-based Representations of High-dimensional CAE Models for Automotive Design Optimization", Leiden University, 2022.
AbstractIn design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance of similar, yet more challenging, design optimization problems. However, engineering design data are unstructured, high-dimensional and often ha...

Tim Puphal, Raphael Wenzel, Benedict Flade, Malte Probst , Julian Eggert , "Importance Filtering with Risk Models for Complex Driving Situations", IEEE ICRAE 2022, 2022.
AbstractSelf-driving cars face complex driving situations with a large amount of agents when moving in crowded cities. However, some of the agents are actually not influencing the behavior of the self-driving car. Filtering out unimportant agents would inherently simplify the behavior or motion planning task for the system. The planning system can then focus on fewer agents to find optimal behavior solutions for the ego agent. This is helpful especially ...

Charlie Street, Bruno Lacerda, Michal Staniaszek, Manuel Mühlig, Nick Hawes , "Context-Aware Modelling for Multi-Robot Systems Under Uncertainty", International Conference on Autonomous Agents and Multiagent Systems (AAMAS), 2022.
AbstractFormal models of multi-robot behaviour are fundamental to plan- ning, simulation, and model checking techniques. However, existing models are invalidated by strong assumptions that fail to capture execution-time multi-robot behaviour, such as simplistic duration models or synchronisation constraints. In this paper we propose a novel multi-robot Markov automaton formulation which mod- els asynchronous multi-robot execution in continuous time...
