摘要：The invention relates to a tactile sensor capable of obtaining information for a plurality of degrees of freedom at each point on a surface by introducing multi-channel sensing that uses color or optical spectrum to an optical tactile sensor. An optical tactile sensor is provided with a tactile section and imaging means, the tactile section comprising a transparent elastic body and a plurality of groups of markers provided inside the elastic body, each marker group being made up of a number of colored markers, with markers making up different marker groups having different colors for each group, and behavior of the colored markers when an object touches the elastic body being photographed by the imaging means. Preferably, the marker groups have mutually different spatial arrangements.
