**A Durable Vision-Based Tactile Fingertip for Robotic Manipulation**

针对视觉式触觉传感器易磨损问题，提出带TPU保护膜和可更换感知盒的触觉指尖，并用加速实验验证耐久性。

## 核心要点

- 动机是现有商用视觉式触觉传感器易受磨损和反复集中载荷影响。
- 方法采用软硅胶、无颜料纹理薄TPU保护膜，以及可更换感知盒结构。
- 在砂磨和重复探针测试中，所开发传感器耐久性较商用品提升两个数量级以上。
- 损伤逐渐发展且对触觉成像干扰较小，快速更换感知盒有助于维护。

**验证范围与局限**：验证范围为旋转鼓砂磨和重复探针两类加速实验，摘要未提及真机操作任务。

## 英文摘要 (Abstract)

Currently available commercial vision-based tactile sensors provide rich contact information but remain vulnerable to abrasion and repeated concentrated loading, limiting their use in demanding robotic applications. This work presents a durable tactile fingertip comprising a soft silicone gel with a nonpigmented, textured, thin thermoplastic-polyurethane protective film and a replaceable sensing cartridge. Durability was evaluated using two accelerated laboratory procedures: a rotating-drum sanding test and a repetitive probe test applying 39.2 N (4.0 kgf) at 45 cycles per minute. Under the defined sanding conditions, the developed sensor reached the protective-film rupture endpoint after approximately 2-3 hours. During repetitive probe testing, all nine developed sensors remained functionally usable when testing was discontinued: seven after 5 days, one after 6 days, and one after 8 days. Commercial GelSight Mini and DIGIT specimens exhibited initial surface-film rupture after approximately 24-30 seconds of sanding and 25-35 minutes of repetitive loading. Damage to the developed sensor progressed gradually and produced little interference with tactile imaging at the test endpoints. These observations establish durability improvements of more than two orders of magnitude under the defined accelerated conditions. Combining increased durability, gradual degradation, and rapid cartridge replacement offers a practical approach to maintainable vision-based tactile sensing for demanding robotic applications.
