Superresolution with an optical tactile sensor
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015 Although superresolution has been studied to huge impact in visual imaging, it is relatively unexplored in tactile robotics. Here we demonstrate a novel optical sensor design (the TacTip) capable of achieving 40-fold localization superresolution to 0.1mm accuracy compared with a 4mm resolution between tactile elements.

Abstract Next generation robot grippers should be equipped with tactile sensors providing a sense of touch similar to the human hand by measuring the local distribution of forces on the surface. In this Paper two realized sensor types are presented. The first type of tactile sensors are capacitive sensors.
