Abstract: This investigation is all about determining condition number for four link planner serial manipulator. Condition number which measures the accuracy of end effector velocity is obtained from the Jacobian matrix of the four link planner serial manipulator. Inverse of a non-square matrix in the calculation of the condition number. Pseudo inverse procedure is used for the calculation of inverse of jacobian matrix using condition number. Isotropic condition for manipulator is found. “MAT Lab” 6.1.0 version is used to determine the condition number which is recently developed for complex matrix manipulations. A computer program in “MAT Lab” is written for finding Jocobian matrix, inverse of Jacobian matrix, norm of jacobian and norm of Jacobian matrix and the condition number for various input joint angles and link lengths
