Layered e-skin for Shear Sensing
Qingzheng Cong, Alexis W. M. Devillard, Abu Bakar Dawood +7
This paper presents a stacked two-layer force-sensing resistor (FSR) array designed for robotic fingertips that combines high-resolution pressure mapping with shear-force estimatio…
Soft Eversion Robots for Colonoscopy: Challenges, Open Problems, and Emerging Solutions
Cem Suulker, Thomas Mack, Qingzheng Cong +4
Conventional colonoscopy remains limited by patient discomfort and procedural risks, motivating research into compliant robotic alternatives. Eversion robots, which advance via pre…
TacVerse: A Multi-Sensor Dataset and Benchmark for Cross-Sensor Vision-Based Tactile Perception
Lan Wei, Gurmeher Khurana, Sirine Bhouri +6
Vision-based tactile sensors (VBTSs) enable robots to infer contact geometry and force-related cues by imaging deformation through an internal camera, yet generalisation across sen…
TacEva: A Performance Evaluation Framework For Vision-Based Tactile Sensors
Qingzheng Cong, Steven Oh, Wen Fan +3
Vision-Based Tactile Sensors (VBTSs) are widely used in robotic tasks because of the high spatial resolution they offer and their relatively low manufacturing costs. However, varia…
Design and Benchmarking of A Multi-Modality Sensor for Robotic Manipulation with GAN-Based Cross-Modality Interpretation
Dandan Zhang, Wen Fan, Jialin Lin +5
In this paper, we present the design and benchmark of an innovative sensor, ViTacTip, which fulfills the demand for advanced multi-modal sensing in a compact design. A notable feat…
