This study addresses one of the most important performance criteria, namely the robot’s repeatability, from the e-quality for manufacture (EQM) point of view within the framework of networked robotic system. Real-time monitoring and control of remotely located robots allow the operators to continuously assess the risk of robot’s non-repeatability. The elaborated methodology of predictive modeling on the risk of robot’s non-repeatability consists of three stages: (1) regression analysis on the association between the disturbing factors and the key performance variables that influence the robot repeatability; (2) probabilistic assessment on the admissible deviations of key performance variables that simulate the robot operations as probabilities of job service without failures in the queueing system; and (3) Bayesian assessment on the risk of non-repeatability for the robot operations. The proposed methodology is expected to reduce the risk of robot’s non-repeatability, which is better suited for today’s networked, distributed production environment, where quality standards are stringent and customer expectations are high.
► A novel approach for real-time risk assessment of robot’s non-repeatability.
► Reduce the risk of robot being outside the permissible tolerance ranges.
► Remote monitoring of robot’s positioning accuracy over the network.
► Enables proactive and timely actions to be taken prior to the production of defects.
