TACTILE SENSOR AND SIGNAL PROCESSING METHOD FOR A TACTILE SENSOR

摘要

The invention is a signal processing method for a tactile sensor, said tactile sensor having a tactile surface and elementary sensors (10) being suitable for three dimensional force sensing and being arranged along the tactile surface, wherein sensing is carried out by reading signals of the elementary sensors (10). For each elementary sensor (10), force components (Tx, Ty, Sn) measured along three spatial axes normal to each other are determined, three force maps are generated from the respective force components (Tx, Ty, Sn) along the same axis, the three force maps are evaluated, and then the results of the three evaluations are jointly evaluated. The invention also relates to a tactile sensor having a tactile surface and elementary sensors (10) suitable for three dimensional force sensing and arranged along the tactile surface. The inventive tactile sensor comprises sensor units consisting of four elementary sensors (10) arranged in the corner points of a square.
