Experiments with redundant parallel calibration and measuring machine RedCaM

This paper introduces a new calibration and measurin g machine RedCaM for 6 DOF with minimized transfer error. As a parallel structure it profits from the fact that sensors errors are not chaining. The redundancy of sensors provides better accuracy, self-calibration pr perty and very good ratio between errors of part icular sensors and resulting error of end effector position. Altogether it creates a new principle of measuring a d calibration. The paper describes results of experimental m easurements with the first prototype of RedCaM and their comparison with results of simulations. © 2007 University of West Bohemia. All rights reserved.
