Abstract

Current maintenance research often includes modeling the equipment degradation to determine degradation and in particular, when any degradation will exceed a specified threshold. Such models can provide critical intelligence to determine an impending failure and promote the timely scheduling of maintenance, yet, the models require equipment data. While healthy state data can be readily captured from a system, degraded or failure state data is more difficult to acquire because equipment are normally operating in a healthy state. A digital twin can model the degradation process and generate data to predict a system's future health state. This paper presents a procedure for building a digital twin to model and generate data of a robot workcell during operation. Future work will focus on the incorporation of robot degradations and generate data that can be input into analytics and the results used to predict future states of the robot and support decision-making.
