Over the past few years, the concept of multi-directional three-dimensional (3D) printing has
been introduced to print complex shapes and overhang geometry. This technique requires …

In this contribution, the Jacobian analysis of a four-legged six-degrees-of-freedom
decoupled parallel manipulator is carried out through the screw theory. As an intermediate …

The driving mechanism of an axisymmetric vectoring exhaust nozzle (AVEN) is a 3-degrees-
of-freedom (3-DOF) parallel manipulator (PM) with a centering device. According to the …

A novel 3-degrees of freedom (DOF) RPU+ UPU+ SPU parallel manipulator (PM) is
proposed in this study, and its complete kinematics and stiffness are studied systematically …

Despite significant performance advantages, the intractable forward kinematics have always
restricted the application of parallel manipulators to small posture spaces. Traditional …
