The problem of grasping is widely studied in the The problem of semantic part decomposition is still an robotics community. This project focuses on the open problem and, to the best of our knowledge, there are identification of object graspable features using images no tools available to automatically create a fuzzy ontology and object structural information. The primary from raw data taken from an image. The use of fuzzy DLs for aim is the creation of a framework in which the information object recognition has been investigated in some works such gathered by the vision system can be integrated as [Hudelot et al., 2008], in which little advantage is taken with automatically generated knowledge, from the (partial) fuzzy extension and from the expressivity modelled by means of fuzzy description logics. of the used logic (i.e., no cardinality restrictions are used); furthermore, a preliminary phase of semantic annotation of the images by domain experts has to be performed.
