Abstract: In this paper, an intuitive approach for the mobility analysis of deployable mechanisms involved in a special screw system with two coplanar twist vectors is proposed. First, the coplanar screw system with a pair of ...

Abstract: This paper presents the design and analysis of a three-fingered deployable metamorphic robotic grasper for manipulating large-scale unknown objects. This grasper is composed of three fingers and a single-mobility umbrella-shaped ...

Abstract: This paper presents an intuitive approach for mobility analysis of thin-panel origamis based on a coplanar 2-twist screw system, which consists of a pair of parallel/concurrent line vectors. In this study, we first proved ...

Abstract: This paper proposes a new family of single degree of freedom (DOF) deployable mechanisms derived from the threefoldsymmetric deployable Bricard mechanism. The mobility and geometry of original threefoldsymmetric deployable ...

Abstract: In this paper, we present a virtual chain approach for the mobility analysis of multiloop deployable mechanisms. First, the relative motion of the links of singleloop units in multiloop mechanisms are analyzed using the ...

Abstract: In this paper, a class of large deployable mechanisms constructed by plane-symmetric Bricard linkages is presented. The plane-symmetric Bricard linkage is a closed-loop overconstrained spatial mechanism composed of six ...

Abstract: In this paper, a lightweight high-payload cable-driven serial-parallel manipulator is proposed. The manipulator comprises one 3-degree-of-freedom (3-DOF) shoulder joint and one single-DOF elbow joint. Using a special ...

Abstract: This paper aims at dealing with the deployment vibration problem of the rigid-links deployable mechanism caused by mobility bifurcation. A triangular prismoid deployable mechanism with mobility bifurcation is employed as ...

Abstract: Design strategies for foldable mechanisms have been developed with inspiration from origami. In this study, we investigate a new direction that blocks are folded in a way that origami folds as the ori-blocks to generate a ...

Abstract: This paper presents the design methodology for a single-mobility, large surface-deployable mechanism using irregularly shaped triangular prismoid units. First, we demonstrate that the spherical shell, as the deployed profile ...
