| Abstract: | The paper studied the singularity loci of a new 6-DOF and 3-limbed parallel manipulator,and their precise analytical expressions were obtained by utilizing the parallel manipulator′s inverse kinematic equations and Jacobian matrix.Kinematic analysis reveals three forms of singularity loci,each of which has its own physics meaning.The first two forms of singularity loci were studied and their schematics were given in Figs.5 through 8 in the full paper.The study sheds light on robot′s trajectory planning and control. |
