Learning Hierarchical Domain Models Through Environment-Grounded Interaction
Claudius Kienle, Benjamin Alt, Oleg Arenz +1
Domain models enable autonomous agents to solve long-horizon tasks by producing interpretable plans. However, in open-world environments, a single general domain model cannot captu…
MuTT: A Multimodal Trajectory Transformer for Robot Skills
Claudius Kienle, Benjamin Alt, Onur Celik +4
High-level robot skills represent an increasingly popular paradigm in robot programming. However, configuring the skills' parameters for a specific task remains a manual and time-c…
Shadow Program Inversion with Differentiable Planning: A Framework for Unified Robot Program Parameter and Trajectory Optimization
Benjamin Alt, Claudius Kienle, Darko Katic +2
This paper presents SPI-DP, a novel first-order optimizer capable of optimizing robot programs with respect to both high-level task objectives and motion-level constraints. To that…
Localization and Tracking of User-Defined Points on Deformable Objects for Robotic Manipulation
Sven Dittus, Benjamin Alt, Andreas Hermann +3
This paper introduces an efficient procedure to localize user-defined points on the surface of deformable objects and track their positions in 3D space over time. To cope with a de…
Heuristic-free Optimization of Force-Controlled Robot Search Strategies in Stochastic Environments
Benjamin Alt, Darko Katic, Rainer Jäkel +1
In both industrial and service domains, a central benefit of the use of robots is their ability to quickly and reliably execute repetitive tasks. However, even relatively simple pe…
RoboGrind: Intuitive and Interactive Surface Treatment with Industrial Robots
Benjamin Alt, Florian Stöckl, Silvan Müller +10
Surface treatment tasks such as grinding, sanding or polishing are a vital step of the value chain in many industries, but are notoriously challenging to automate. We present RoboG…
