FasTac: A Curved Multispectral Vision-Based Tactile Sensor for High-Speed High-Precision 3D Shape and Force Perception
Xiaofan Lu, Kaiji Huang, Jiahui Chen +3
Curved tactile fingertips for dexterous manipulation must resolve fine contact geometry, distinguish normal and tangential loads, and capture transient signals. Existing curved vis…
Chronos: A Physics-Informed Full-History Framework for Non-Markovian Long-Horizon Manipulation
Yulin Zhou, Yimeng Wang, Nengyu Wang +9
General-purpose robot policies should be modeled as dynamical systems, yet many VLA and generative imitation policies still rely on present observations or short windows. This Mark…
MTIL: Encoding Full History with Mamba for Temporal Imitation Learning
Yulin Zhou, Yuankai Lin, Fanzhe Peng +4
Standard imitation learning (IL) methods have achieved considerable success in robotics, yet often rely on the Markov assumption, which falters in long-horizon tasks where history…
GelSplitter: Tactile Reconstruction from Near Infrared and Visible Images
Yuankai Lin, Yulin Zhou, Kaiji Huang +4
The GelSight-like visual tactile (VT) sensor has gained popularity as a high-resolution tactile sensing technology for robots, capable of measuring touch geometry using a single RG…
GelFlow: Self-supervised Learning of Optical Flow for Vision-Based Tactile Sensor Displacement Measurement
Zhiyuan Zhang, Hua Yang, Zhouping Yin
High-resolution multi-modality information acquired by vision-based tactile sensors can support more dexterous manipulations for robot fingers. Optical flow is low-level informatio…
