Identification of Industrial Robot Arm Work Cell Use Cases and a Test Bed to Promote Monitoring, Diagnostic, and Prognostic Technologies
Brian A. Weiss, Alexander S. Klinger
The National Institute of Standards and Technology (NIST) is performing research to advance the state of the art in monitoring, diagnostic, and prognostic technologies to enhance decision-making at the factory floor to promote smarter maintenance and control strategies. A robot system is one focus of this research where the manufacturing community would benefit from measurement science (e.g., test methods, metrics, reference datasets) to design, deploy, verify, and validate PHM technologies aimed at a robot system work cell. This research is supported by the development of an industry-representative use case and will be further articulated through the generation of a physical test bed. As an industrial robot arm, by itself, is relatively robust, the overall robot system is more complicated and prone to greater uncertainty in its health degradation over time. A typical robot system work cell includes a robot(s), a robot controller(s), an end-effector(s), sensors, and other supporting automation that are integrated together to perform a specific task (e.g., welding, material handling). Over time, the individual components, and their respective relationships with one another, inside the work cell degrade, likely at different rates, which will impact critical metrics including productivity and quality. Faults and failures can be costly in terms of lost time and lost productivity making it beneficial for manufacturers to acquire advanced warning of if, when, and where a component (or relationship) will fail. NIST's identification of representative manufacturing robot work cell use cases will provide the foundation for which it will construct its own physical test bed. This paper will present various use case options that NIST has considered and highlight the ones that will be the foundation of the physical test bed. Additionally, the initial test bed design will be introduced.
