Influence of Dimensional Deviations on the Positioning Accuracy of Robots with Delta 3 DOF Parallel Structure

Abstract:

In the last years, due to the advantages presented by Delta 3 DOF parallel structure robots, they have been used in the field of high accuracy mechanical processing. In this field, it is demanded that the manufacture of components present high quality. The positioning accuracy for the parallel structure Delta 3 DOF robots can be affected by errors entered from the mechanical structure or by the control and command system. The accuracy class in which the mechanical elements are manufactured can affect the positioning accuracy within the robots with Delta 3 DOF parallel structure. In this paper, the authors study the ways in which the dimensional deviations of the kinematic elements influence the positioning accuracy. The method which is used correlates the dimensional deviations with the positioning accuracy. Therefore, the positioning accuracy of the Delta 3 DOF robots can be established within the design process.
