Virtual models in the case of calibration of the robots with parallel topology

This paper presents basic elements concerning calibration of machine-tools with parallel topology. The main advantages of this new kind of machine-tools consist on their reconfigurability and also on their high accuracy. The main point of the paper is that two methods which may be used for calibration are presented. The corresponding algorithm was in mobile implemented and virtual models, used for simulation and validation of the methods were developed. The paper presents also numerical results obtained with the developed virtual models.
