Due to the complex structures of multi-limbed parallelrobots,conventional parallelrobots generally have limited workspace,complex kinematics,and complex dynamics,which increases the application difficulty of parallelrobot in industrial *** solve the above problems,this paper proposes a single-loop Sch?nflies motion parallelrobot with full cycle rotation,the robot can generate Sch?nflies motion by the most simplified *** novel Sch?nflies motion parallelrobot is a two-limb parallel mechanism with least links and joints,and each limb is driven by a 2-degree of freedom(DOF)cylindrical driver(C-driver).The full cycle rotation of the output link is achieved by“…R-H…”structure,where the revolute(R)and helical(H)joints are ***,kinematics,workspace and singularity analysis of the novel Sch?nflies motion parallelrobot are ***,dynamic model is formulated based on the principle of virtual ***,a pick-and-place task is implemented by the proposed Sch?nflies motion parallelrobot and a serial SCARA robot,*** simulation results verify the correctness of the theoretical ***,dynamics performances of the proposed Sch?nflies motion parallelrobot and a serial SCARA robot are compared,which reveal the performance merits of the proposed Sch?nflies motion parallelrobot.
