Tactile sensing is one of the key technologies to realize an intelligent robotic system. For tactile sensing, generally, a resistive sensing device based on strain gauges and conductive polymers has been used. In these typical devices, the spatial resolution provided by them is low even if multiple sensor elements are arranged together, it may be difficult to measure detailed distribution about the contact and detect small objects. In order to realize a high spatial resolution, there have been many studies on tactile sensors employing camera. In this talk, I would like to review this kind of optical tactile sensors and methods how tactile information is converted to optical one to be captured by camera. Then I introduce a combined tactile and proximity sensing device using multiple small cameras for measuring both tactile and proximity information at a high spatial resolution and its application to robotic grasp control.
