Human civilization right from the stone age requires machines for their sustenance on the earth, the early age stone tools or the discovery of the wheel was the landmarks in the history of civilization but as the human race develops more and more complex machineries comes into existence and the basis of all these machines are the kinematic chains. The present study is to look into the available categorization of these kinematic chains in the literature and to develop a new and effective method of categorization of the available non-isomorphic single degree of freedom eight link chains and to find the automorphs present in each chain.
