爪色触覚センサの高精度化に向けた3軸力計測装置の開発

抄録

We develop a tactile sensor that estimates the three-axis force applied to the finger pad from the nail color, utilizing the relationship between the deformation of the finger pad and the change in nail color. To improve the accuracy of this sensor, it is important to develop experimental equipment that can more precisely measure the three-axis force applied to the finger pad. The experimental equipment used to create datasets in previous studies restrained one of the three axes and only measured two-axis forces, which meant that the force applied in the restrained direction was unknown. In this study, we develop a measuring apparatus that can simultaneously measure three-axis forces, collect a new dataset, and attempt to improve the accuracy of the nail color sensor.
