Abstract: The detection of isomorphism among kinematic chains and their derived mechanism has been a hot area of research for the last several years. In this paper a joint resistance method is proposed and it is tested for planar kinematic chains up to 12 links. In this method, the kinematic chains are represented in form of resistance graph and from that graph a Laplacian matrix is generated which is further transformed into an equivalent joint resistance matrix. The sums of the squares of resistances are used as an index for isomorphism identification among kinematic chains. This method is successfully examined for one degree of freedom, 6, 8, 10 links planar kinematic chains, 9 links two degree of freedom KC and 10 links three degree of freedom planar kinematic chains.
