A new spatial mechanism was developed in this work. A mathematical model for this new mechanism was established by the rotation vector method. By using Matlab functions, spatial position analyses for the variable link-length mechanism and the variable link-twist-angle mechanism were conducted. The track of the same point on a link rod was drawn and analyzed. The analyzing method proved correct. The method provides a theoretical foundation for designs of robot, picking machine, planting mechanism and so on.
