Time-Division Multiplexing Actuation in Tendon-Driven Arms: Lightweight Design and Fault Tolerance
Shoujie Li, Changqing Guo, Jianle Xu +4
Robotic manipulators for aerospace applications require a delicate balance between lightweight construction and fault-tolerant operation to satisfy strict weight limitations and en…
SandWorm: Event-based Visuotactile Perception with Active Vibration for Screw-Actuated Robot in Granular Media
Shoujie Li, Changqing Guo, Junhao Gong +3
Perception in granular media remains challenging due to unpredictable particle dynamics. To address this challenge, we present SandWorm, a biomimetic screw-actuated robot augmented…
CEI: A Unified Interface for Cross-Embodiment Visuomotor Policy Learning in 3D Space
Tong Wu, Shoujie Li, Junhao Gong +4
Robotic foundation models trained on large-scale manipulation datasets have shown promise in learning generalist policies, but they often overfit to specific viewpoints, robot arms…
UltraTac: Integrated Ultrasound-Augmented Visuotactile Sensor for Enhanced Robotic Perception
Junhao Gong, Kit-Wa Sou, Shoujie Li +5
Visuotactile sensors provide high-resolution tactile information but are incapable of perceiving the material features of objects. We present UltraTac, an integrated sensor that co…
AllTact Fin Ray: A Compliant Robot Gripper with Omni-Directional Tactile Sensing
Siwei Liang, Yixuan Guan, Jing Xu +5
Tactile sensing plays a crucial role in robot grasping and manipulation by providing essential contact information between the robot and the environment. In this paper, we present…
VET: A Visual-Electronic Tactile System for Immersive Human-Machine Interaction
Cong Zhang, Yisheng Yang, Shilong Mu +4
In the pursuit of deeper immersion in human-machine interaction, achieving higher-dimensional tactile input and output on a single interface has become a key research focus. This s…
