The kinematical equation of a 3-PCR parallel robot was analyzed in geometrical method. With certain parameters specified, the corresponding workspace was drawn out with a 3D software INVENTOR. By analyzing workspace of each limb, the faces and lines of the workspace boundary was determined and then the singularity of the workspace was discussed.
