Comparison of Serial and Quasi-Serial Industrial Robots for Isotropic Tasks

Abstract

The paper presents a new approach for comparison of serial and quasi-serial robots in industrial applications. In contrast to other works, it is based on evaluation of maximum compliance errors in the working area for isotropic tasks. It is proved that for large-scale isotropic tasks quasi-serial manipulators with kinematic parallelograms are preferable, while for small task dimensions' serial manipulators provide better accuracy.
