Robotics Team Finds Artificial Fingerprints Improve Tactile Abilities

National University of Singapore researchers have demonstrated how adding artificial fingerprints to robot fingers can increase tactile sensation, enabling the robot to discern the differences in the curvature of objects. The researchers, led by Saba Salehi, John-John Cabibihan, and Shuzhi Sam Ge, built a touch sensor consisting of a base plate, embedded sensors, and a raised ridged surface. The researchers tested the sensor in a variety ways to determine if they were able to use it to sense things in different ways, specifically as it was applied to flat, edged, and curved objects. The researchers found that the raised sensor provided more feedback information than the one with the flat surface, so much so that they were able to tell the difference in the three types of objects with 95.7 percent accuracy.
