CÁLCULO DE LA RIGIDEZ DE UN ROBOT INDUSTRIAL DE SEIS GRADOS DE LIBERTAD
Resumen
Resumen
Como parte de una investigación para producir un sistema de compensación on-line para el proceso de Roll Hemming, proponemos un método para calcular la matriz de rigidez de las juntas de un robot industrial de seis grados de libertad. Este análisis fue hecho aplicando solo una fuerza sobre la el punto central de la herramienta, esta fuerza solo actuaba en la dirección Z del marco de referencia. El experimento puede ser mejorado sin embargo los resultados pueden ser utilizados como referencia para experimentos relacionados con robots industriales.

CALCULATION OF THE RIGIDITY OF AN INDUSTRIAL ROBOT OF SIX DEGREES OF FREEDOM
Abstract
As part of a research to produce an on-line compensation system for Roll Hemming process, we propose a method to calculate the joint stiffness matrix of an industrial robot of six degrees of freedom. This analysis was done applying only one force over the tool center point, this force only acted in the Z world frame reference direction. The experiment can be improved nevertheless the values can be used as reference for experiments related with industrial robots.
Keywords: Industrial robot, Roll Hemming, Stiffness.
