RISClassification of Screw Systems Composed of Three Planar Pencils of Lines for Singularity Analysis of Parallel Mechanisms1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Screw systems composed of (the sum of) three planar pencils of lines are closely related to the singularity analysis of a number of threelegged parallel manipulators (PMs) in which the passive joints in each leg are a ...
Determination of the Workspace of a Three Degrees of Freedom Parallel Manipulator Using a Three Dimensional Computer Aided Design Software Package and the Concept of Virtual Chains1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The determination of workspace is an essential step in the development of parallel manipulators. By extending the virtualchain (VC) approach to the type synthesis of parallel manipulators, this technical brief proposes a ...
