Abstract
In this paper, we present new properties of reciprocal screws and use these properties to investigate singular configurations of 6R serial mechanisms. Similarities between the statics of objects under six external forces and the instantaneous kinematics of 6R serial mechanisms are also demonstrated using the same method. Previous results on the linear dependency of two and three screws are verified as special cases of our generalized method which deals with the linear dependency of four to six screws
