Abstract: This paper presents a systematic approach on structural synthesis of serial-parallel hybrid mechanisms from the point of displacement group theory and mathematical logic. The hybrid mechanisms can ...

Abstract: When a serial manipulator is at a singular configuration, the Jacobian matrix will lose its full rank causing the manipulator to lose one or more degrees of freedom. This paper presents a ...

Abstract: This paper presents a metamorphic kinematic pair extracted from origami folds in the context of mechanisms, its evolved metamorphic chain, and the novel metamorphic parallel mechanism. This paper ...

Abstract: This paper presents a novel 4-DOF kinematotropic hybrid parallel manipulator. The topological structure allows for the realization of two translatory and two rotary output motions. Both the ...

Abstract: This paper analyzes the basic forms of 4-DOF spatial motions through the introduction of logical propositions for the topological structural synthesis of multiloop hybrid spatial mechanisms. The ...

Abstract: This paper presents a three-spherical kinematic chain based parallel mechanism that evolved from an origami fold. The new parallel mechanism with symmetrical structure consists of a base, a ...
