Flexible tactile sensor system for robot skin based on LabVIEW

Using carbon black-silicone rubber significant piezoresistive effect, the tactile sensor with interdigitated structure was designed. A flexible tactile sensor array was fabricated to detect the force acted on. The principle of the force detection was analyzed. Connecting the tactile sensor array with data acquisition card and pc, some objects of different shapes were loaded on the tactile sensor array; the detected results were showed by LabVIEW software. The results are in well agreement with the shapes and magnitudes of different force sources. The experiment results prove that the tactile sensor array is correct and sensitive enough to have force-detecting function and can be used as robot sensitive skin.
