Constraint Singularities as C-Space Singularities
This paper examines the phenomenon of constraint singularity of a parallel mechanism, as defined in a recent publication. We focus our attention on the fact that constraint singularities are always singular points of the configuration space of the kinematic chain. As such, they separate distinct configuration space regions and may allow transitions between dramatically different operation modes. All this is exemplified by a multi-operational parallel mechanism that can undergo a variety of transformations when passing through singular configurations.
