Task-Aware Bimanual Affordance Prediction via VLM-Guided Semantic-Geometric Reasoning
Fabian Hahne, Vignesh Prasad, Georgia Chalvatzaki +2
Bimanual manipulation requires reasoning about where to interact with an object and which arm should perform each action, a joint affordance localization and arm allocation problem…
Investigating the Effect of LED Signals and Emotional Displays in Human-Robot Shared Workspaces
Maria Ibrahim, Alap Kshirsagar, Dorothea Koert +1
Effective communication is essential for safety and efficiency in human-robot collaboration, particularly in shared workspaces. This paper investigates the impact of nonverbal comm…
In-Hand Object Pose Estimation via Visual-Tactile Fusion
Felix Nonnengießer, Alap Kshirsagar, Boris Belousov +1
Accurate in-hand pose estimation is crucial for robotic object manipulation, but visual occlusion remains a major challenge for vision-based approaches. This paper presents an appr…
Investigating Active Sampling for Hardness Classification with Vision-Based Tactile Sensors
Junyi Chen, Alap Kshirsagar, Frederik Heller +7
One of the most important object properties that humans and robots perceive through touch is hardness. This paper investigates information-theoretic active sampling strategies for…
TacEx: GelSight Tactile Simulation in Isaac Sim -- Combining Soft-Body and Visuotactile Simulators
Duc Huy Nguyen, Tim Schneider, Guillaume Duret +3
Training robot policies in simulation is becoming increasingly popular; nevertheless, a precise, reliable, and easy-to-use tactile simulator for contact-rich manipulation tasks is…
