Singularity and Kinematics Analysis for a Class of PPUU Mobile Parallel Robots
In this paper a class of mobile parallel robots with the structural configuration of PPUU (Prismatic-Prismatic- Universal-Universal) is investigated in detail. Firstly a singularity analysis corresponding to different configured cases of the revolute axes of the robots U-joint based on the screw theory is developed and a brief comparison of the four cases is carried out. Of all four configuration schemes, only FG xE y x U U P P can avoid a singularity by mechanism design rather than complicated trajectory control. Then the inverse kinematics to the FG xE y x U U P P mobile parallel robot is developed. By a numerical approach, the orientation workspace envelope is mapped. This work provides an analytical basis for the design of an MPR prototype.
