A novel 3(Rc)PU parallel mechanism based on the reconfigurable circular groove cross joint (Rc joint) is proposed. The motion branch transformation relationship and constraint performance evaluation method for the mechanism are studied. According to constrained screw analysis. the (Rc)PU limb provides a constraint couple to the moving platform in one motion mode and no constraint to t... https://www.itsmajorlook.com/great-deal-Chicago-Cubs-Earrings-Round-Design-p21310-limited-grab/
