AI 中文摘要
基于视觉的触觉传感器（VBTS）为机器人操作提供丰富的接触信息，但现有设计往往难以简化并适配人形机器人指尖的尺寸和约束条件。我们提出 GlowTact，一种压力响应的基于视觉的触觉传感机制，可直接可视化接触压力。GlowTact 仅需单色、非方向性照明，原始触觉图像直接表示压力分布，无需显式几何重建。这种简单的传感原理使得触觉传感器能够紧凑、可定制，同时保持高灵敏度和丰富的空间细节。我们展示了克级接触检测、准确的法向力估计以及精细接触几何（包括 M1 螺纹）的重建。这些结果确立了 GlowTact 作为一种适用于紧凑人形指尖的实用新型传感技术，将耐用的丁腈橡胶膜和简单光学设计与灵敏且信息丰富的触觉感知相结合。
英文摘要
Vision-based tactile sensors (VBTS) provide rich contact information for robotic manipulation, but existing designs can be hard to simplify and adapt to the size and constraints of humanoid fingertips. We introduce \textbf{GlowTact}, a pressure-responsive vision-based tactile sensing mechanism that directly visualizes contact pressure. \textbf{GlowTact} requires only single-color, non-directional illumination, and the raw tactile image directly represents the pressure distribution without explicit geometry reconstruction. This simple sensing principle enables compact, customizable tactile sensors while preserving high sensitivity and rich spatial detail. We demonstrate gram-scale contact detection, accurate normal-force estimation, and reconstruction of fine contact geometry, including M1 screw threads. These results establish \textbf{GlowTact} as a practical new sensing technology for compact humanoid fingertips, combining a durable nitrile membrane and simple optical design with sensitive and information-rich tactile perception.
