Abstract

A method for recognizing both the three-dimensional object shapes and their sizes by grasping them with an antropomorfic five-finger artificial hand is described. The hand is equipped with the position sensing elements in the joints of the fingers and with the tactile transducer net on the palm surface. The linguistic method uses formal grammars and languages for the pattern description. The recognition is multilevelly hierarchically arranged, every level being different from the others by the formal language which has been used. On every level the pattern description is generated and verified from the syntactical and semantical points of view. The results of the implementation of the recognition of cones, pyramides, spheres, prisms and cylinders are presented and discussed.
