Problems Regarding Singularities Analysis of a 3-RRR Parallel Mechanism

Article Preview

Abstract:

The paper presents some authors results regarding working quality inside workspace of a 3 DoF, 3 RRR planar parallel mechanism, used as parallel robot structure. Namely we deal with singularities avoidance inside workspace as is wide known in scientific literature this represents a major disadvantages of these mechanisms. To this purpose, the configuration determinant notion has been used as principal mechanism work parameter.
