Workspace, Joint space and Singularities of a family of Delta-Like Robot
In , we describe the workspace, the joint space and the singularities of a family of delta-like parallel robots by using algebraic tools. The different func- tions of SIROPA library are introduced, which is used to induce an estimation about the complexity in representing the singularities in the workspace and the joint space. A Gröbner based elimination is used to compute the singularities of the manipulator and a Cylindrical Algebraic Decomposition algorithm is used to study the workspace and the joint space. From these algebraic objects, they propose some certified three-dimensional plotting describing the shape of works- pace and of the joint space which will help the engineers or researchers to decide the most suited configuration of the manipulator they should use for a given task. Also, the different parameters associated with the complexity of the serial and parallel singularities are tabulated, which further enhance the selection of the different configuration of the manipulator by comparing the complexity of the singularity equations.
