Abstract
An optical pressure sensor useable in robotic applications. The optical pressure sensor can be included in a robotic grasping device. The pressure sensor includes a sensor structure having an interior wall and indicia. The indicia, apparent by viewing the interior wall, appearance change in response to pressure on the structure. An image sensor is positioned to view at least a portion of the interior wall, wherein the image sensor is configured to provide images of the indicia as the sensor structure is subject to pressure.
