Abstract :
In this paper, a seven DOF anthropomorphic arm model defined by zero-position notation is used to study the kinematically singular configurations of this arm. The important findings of this study are: (1) A relationship is shown between the rank of Jacobian matrix and the number of corresponding reciprocal screws for singular configurations of any three dimensional manipulator arm. (2) By investigating the geometrical positions of this model, its various singular configurations are identified
