A geometrical approach for the singularity analysis of a 3-RRS parallel manipulator
MetadataTüm öğe kaydını göster
Identifying singularity manifolds of parallel manipulators analytically is a hard task due to their complex kinematics and passive joints. This study proposes to use the geometrical conditions of singularities in order to identify the singularity manifolds for a 3-RRS parallel manipulator. The singularity surfaces for both inverse and forward kinematics singularities are obtained and plotted.
