Abstract: This paper presents a novel metamorphic 8R linkage extracted from a kirigamifold with pregrooved creases and two overconstrained 6R linkages evolved from the 8R linkage by taking the concept of metamorphosis in the sense ...

Abstract: This paper presents for the first time a novel two degrees of freedom (2DOF) singlelooped dualplanesymmetric spatial eightbar linkage with exact straightline motion. Geometry and kinematics of the eightbar linkage are ...

Abstract: Rolling contact has been used by robotic devices to drive between configurations. The degrees of freedom (DOFs) of rolling contact pairs can be one, two, or three, depending on the geometry of the objects. This paper aimed ...

Abstract: This paper presents two integrated planarspherical overconstrained mechanisms that are inspired and evolved from origami cartons with a crashlock base. Investigating the crashlock base of the origami cartons, the first ...

Abstract: This paper presents the Bennett planospherical hybrid linkage and proposes a novel metamorphic parallel mechanism consisting of this planospherical linkage as part of limbs. In light of geometrical modeling of the Bennett ...

Abstract: This paper explores a class of metamorphic and reconfigurable linkages belonging to both Waldron's double-Bennett hybrid linkage and Bricard linkages, which include three novel symmetric Waldron–Bricard metamorphic and ...

Abstract: The parallel mechanism with a reconfigurable platform retains all advantages of parallel mechanisms and provides additional functions by virtue of the reconfigurable platform, leading to kinematic coupling between limbs ...

Abstract: This paper provides an approach to model the reaction force of origami mechanisms when they are deformed. In this approach, an origami structure is taken as an equivalent redundantly actuated mechanism, making it possible ...

Abstract: In order to obtain a comprehensive list of possible mechanisms with various choices of both R and P pairs and mechanism inversion of planar mechanisms, a new structural synthesis method is developed by integrating Assur ...

Abstract: This paper presents a novel design of extensible continuum robots in light of origamiinspired folding techniques. The design starts from a modularized crease pattern, which consists of two triangular bases and three waterbomb ...
