TacClip: a clip-on sensor measures dynamic contact forces without covering the fingerpads
Yuqian Ye, Hao Li, Jingxi Xu +3
TacClip is a minimally encumbering wearable device for recording fingertip deformation caused by contact forces and vibrations. It can be combined with vision- or glove-based hand…
Fiber Bragg Grating Whiskers for Bioinspired Hydrodynamic Perception on Underwater Robots
Hao Li, Tianyu Tu, Siyue Yao +7
Harbor seals track hydrodynamic trails with their vibrissae, enabling passive perception of moving targets in dark or turbid water. Inspired by this capability, we present compact…
MISTac: A Vision-Based Tactile Sensor for Minimally Invasive Surgery
Robin Koch, Annabella Mascot, Rayan Younis +5
Minimally invasive and robot-assisted surgery offer many advantages over traditional open surgery, but deprive surgeons of tactile feedback and the ability to palpate tissue with t…
Multisensory Continual Learning: Adapting Pretrained Visuomotor Policies to Force
Jaden Clark, Changhao Wang, Yihuai Gao +5
Robot manipulation often relies on sensory feedback beyond vision, particularly in contact-rich settings where force, tactile, or audio signals reveal interaction states that are n…
Long-Reach Robotic Cleaning for Lunar Solar Arrays
Stanley Wang, Velin Kojouharov, Long Yin Chung +2
Commercial lunar activity is accelerating the need for reliable surface infrastructure and routine operations to keep it functioning. Maintenance tasks such as inspection, cleaning…
UMI-Underwater: Learning Underwater Manipulation without Underwater Teleoperation
Hao Li, Long Yin Chung, Jack Goler +5
Underwater robotic grasping is difficult due to degraded, highly variable imagery and the expense of collecting diverse underwater demonstrations. We introduce a system that (i) au…
