Abstract
New study results on robotics have been published. According to news originating from China Jiliang University by NewsRx editors, the research stated, “The international standard ISO 9283:1998 is popular for performance tests of industrial robots at present.” Financial supporters for this research include National Natural Science Foundation of China. The news journalists obtained a quote from the research from China Jiliang University: “It is desirable that the tests described in this standard should be sensitive to error sources of robot end positioning/ orientation. In this paper, firstly, the kinematic and the joint stiffness model parameters are identified experimentally for two models of 6-DOF (Degree of Freedom) serial in-dustrial robots (i.e., the ABB IRB 1410 and UR5 robots). Then, the standard deviations of the de-rived model parameters are obtained as error inputs for the sensitivity analysis of the performance tests including the positioning/orientation accuracy/repeatability tests. By simulating the error sen-sitivity of the positioning/orientation accuracy/ repeatability test methods for industrial robots, it is analyzed whether the tests described in the ISO 9283:1998 Standard are sensitive to the focused er-ror sources, showing the limitations of the evaluation index of the ISO 9283:1998 Standard.. The results show that for 6-DOF serial industrial robots, the positioning accuracy test is the key to de-termining their motion performance. The orientation accuracy and repeatability tests are not neces-sary if the positioning accuracy and repeatability tests can be done for 6-DOF serial industrial robots.”
