What Matters, When? Diagnosing and Improving Conditional Visual Grounding in Visuomotor Imitation Policies
Vivek Chavan, Pengtao Xie, Yahuan Shi +3
Visuomotor imitation policies can achieve high performance under in-distribution visual conditions yet fail when visually similar objects or receptacles are introduced. We study th…
Towards Neuro-Symbolic Procedural Reasoning for Long-Horizon Vision-Language-Action Manipulation
Vivek Chavan, Yahuan Shi, Oliver Heimann +2
Vision-language-action (VLA) models can execute short manipulation skills, but remain brittle in long-horizon procedures requiring persistent task state, dependency-aware reasoning…
SynthRender and I-AsSET: Open-Source Framework and Dataset for Bidirectional Sim-Real Transfer in Industrial Object Perception
Jose Moises Araya-Martinez, Thushar Tom, Adrián Sanchis Reig +3
Object perception is fundamental for tasks such as robotic material handling and quality inspection. However, modern supervised deep-learning models require large annotated dataset…
Decomposition of Industrial Systems for Energy Efficiency Optimization with OptTopo
Gregor Thiele, Theresa Johanni, David Sommer +1
The operation of industrial facilities is a broad field for optimization. Industrial plants are often a) composed of several components, b) linked using network technology, c) phys…
Laser engineering of biomimetic surfaces
E. Stratakis, J. Bonse, J. Heitz +12
The exciting properties of micro- and nano-patterned surfaces found in natural species hide a virtually endless potential of technological ideas, opening new opportunities for inno…
Modelling periodic structure formation on 100Cr6 steel after irradiation with femtosecond-pulsed laser beams
George D. Tsibidis, Alexandros Mimidis, Evangelos Skoulas +4
We investigate the periodic structure formation upon intense femtosecond pulsed irradiation of chrome steel (100Cr6) for linearly polarised laser beams. The underlying physical mec…
Properties of Surface Plasmon Polaritons on lossy materials: Lifetimes, periods and excitation conditions
Thibault J. -Y. Derrien, Jörg Krüger, Jörn Bonse
The possibility to excite Surface Plasmon Polaritons (SPPs) at the interface between two media depends on the optical properties of both media and geometrical aspects. Specific con…
Rippled area formed by surface plasmon polaritons upon femtosecond laser double-pulse irradiation of silicon: the role of carrier generation and relaxation processes
Thibault J. -Y. Derrien, Jörg Krüger, Tatiana E. Itina +3
The formation of laser-induced periodic surface structures (LIPSS, ripples) upon irradiation of silicon with multiple irradiation sequences consisting of femtosecond laser pulse pa…
