RISA Novel Method for Constructing Multimode Deployable Polyhedron Mechanisms Using Symmetric Spatial Compositional Units
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel construction method is proposed to construct multimode deployable polyhedron mechanisms (DPMs) using symmetric spatial RRR compositional units, a serial kinematic chain in which the axes of the first and the third ...
A Rolling 8 Bar Linkage Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a rolling mechanism constructed by a spatial 8bar linkage is proposed. The eight links are connected with eight revolute joints, forming a single closedloop with two degrees of freedom (DOF). By kinematic ...
Design of Deployable Mechanisms Based on Wren Parallel Mechanism Units
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a series of deployable mechanisms based on n-UU (universal joint) Wren parallel mechanism (PM) units, which undergo one degree-of-freedom (DOF) Borel–Bricard motion. First, the PM unit is developed into ...
Two Actuation Methods for a Complete Morphing System Composed of a VGTM and a Compliant Parallel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a complete morphing system consisting of a variable geometry truss manipulator (VGTM) is presented that is fully covered by a flexible panel skin. Two approaches are studied for the morphing control. The ...
