WebJacobian computation procedure [1] by which a systematic, general method is used to derive the Jacobian matrice. Jacobian matrices analysis reveals that they are not full rank matrices. So, there are configurations at which Jacobians are rank-deficient. These configurations are named as Kinematic Singularities. WebMar 29, 2024 · The singularity can be found by setting the determinant of the Jacobian matrix to zero. The manipulability measure [ 1] is proposed to observe the singularity of the manipulator. In that sense, a large manipulability value means that the configuration is far from the singularity.
