RISLie Group Based Type Synthesis Using Transformation Configuration Space for Reconfigurable Parallel Mechanisms With Bifurcation Between Spherical Motion and Planar Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates novel reconfigurable parallel mechanisms with bifurcation between planar subgroup SE(2) and rotation subgroup SO(3) based on a transformation configuration space. Having recollected necessary ...
Finite Displacement Screw Operators With Embedded Chasles’ Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rigid body displacement can be presented with Chasles’ motion by rotating about an axis and translating along the axis. This motion can be implemented by a finite displacement screw operator ...
A Kirigami Inspired 8R Linkage and Its Evolved Overconstrained 6R Linkages With the Rotational Symmetry of Order Two
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
A Spatial Eight Bar Linkage and Its Association With the Deployable Platonic Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Posture, Workspace, and Manipulability of the Metamorphic Multifingered Hand With an Articulated Palm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel multifingered hand with an articulated palm that makes the hand adaptable and reconfigurable. The posture of the new multifingered hand is enhanced by the additional ...
A Polynomial Formulation of Inverse Kinematics of Rolling Contact
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Structure Synthesis of Single-Driven Metamorphic Mechanisms Based on the Augmented Assur Groups
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new way of structure composition of single-driven metamorphic mechanisms to develop a systematic and modularized structure synthesis methodology of metamorphic mechanisms based ...
Axis Constraint Analysis and Its Resultant 6R Double-Centered Overconstrained Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the 6R overconstrained mechanisms by looking at an arrangement that axes intersect at two centers with arbitrary intersection-angles. From the close-loop matrix equation ...
Reciprocity-Based Singular Value Decomposition for Inverse Kinematic Analysis of the Metamorphic Multifingered Hand
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With a new type of multifingered hands that raise a new philosophy in the construction and study of a multifingered hand, this paper is a follow-on study of the kinematics of the metamorphic ...
Reconfiguration of Spatial Metamorphic Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates reconfiguration of metamorphic mechanisms as a typical character of topological change of the mechanisms. Metamorphic mechanisms with reconfigurable topology provide changed ...
