Cover Story: The study parameters of SE(3) may be used to describe the joint space of parallel robots and the constraint equations may be further used to define new parameterizations for kinematic, workspace, and singularity analysis. This method is suitable for various robotic fields such as industry, aerospace, medical, and high-precision applications. View this paper.
