Abstract
A new type of four degree of freedom (DOF) symmetric parallel mechanism (PM) with Schönflies motion is proposed based on the topological structure synthesis. The type synthesis process of the PM is carried out by using the theory of POC set. The new mechanism possesses the properties of folding characteristic, extensibility and large coverage of workspace in XY plane. The forward kinematics is solved by Sylvester’s dialytic elimination in Maple. This research has certain theoretical significance for the synthesis and analysis of the other PM.
