摘要:

提出了一种新型的机器人柔性手指触觉感知机构。受哺乳动物本体感觉机制的启发,该方法从附着在手指肌腱上的应变传感器推断触觉信息。我们进行实验,以测试所提出的结构的触觉感知能力,我们的结果表明,这种方法是能够触诊的纹理和刚度在两个外展和屈曲接触。在系统交叉验证下,该系统对纹理和刚度的识别准确率分别达到100%和99.7%,验证了该方法的可行性。此外,我们使用统计工具来确定提取的各种特征的分类的重要性。

英文摘要:

In this paper, a novel tactile sensing mechanism for soft robotic fingers is proposed. Inspired by the proprioception mechanism found in mammals, the proposed approach infers tactile information from a strain sensor attached on the finger's tendon. We perform experiments to test the tactile sensing capabilities of the proposed structures, and our results indicate this method is capable of palpating texture and stiffness in both abduction and flexion contact. Under systematic cross validation, the proposed system achieved 100% and 99.7% accuracy in texture and stiffness discrimination respectively, which validate the viability of this approach. Furthermore, we use statistics tools to determine the significance of various features extracted for classification.
