In support of COVID-19 response efforts, Ginkgo Bioworks created an 18,000-square-foot coronavirus testing facility, responsible for processing tens of thousands of tests daily. To meet this growing demand for COVID testing, Ginkgo reached out to DMC to develop and implement an automated testing solution to replace their existing mostly manual system.
This large-scale project can be divided into three main components. First, DMC used our application development expertise to write multiple drivers. These drivers were responsible for integrating our customized automation system with their existing pieces of various nonstandard lab equipment. Next, DMC designed a custom SCADA system, which served as the user interface (UI) for the entire laboratory and the database infrastructure (mainly for CLIA compliance). Lastly, DMC developed and built the automation system itself, which will be the focus of this case study.
Since the facility is so massive and the testing process is very complex, the testing line needed to be as flexible as possible. Therefore, the line was divided into work cells in which a small step of the process was performed in each. To return a test result, each sample needed to pass through every cell.
These work cells were spread throughout the facility and connecting them was a MagneMotion transport system with three work groups. The samples travelled along this system to each work cell. DMC then designed Control GuardLogix PLCs to act as Line PLCs for the transport system—i.e., responsible for routing the samples and keeping track of where they are in the testing process. We also utilized Rockwell’s independent cart technology in this system to provide a standard architecture for how samples are routed throughout the facility. With thousands of sensitive biological samples traveling about a mile from start to finish during the testing process, it was critical that we had a system robust and reliable enough to handle so much data.
Due to the nature of certain lab operations, the system was separated between two laboratory rooms. DMC connected the rooms through an automated MagneMotion elevator to convey movers from one area to the other. The custom-designed elevator featured indepdendent, synchronous Allen Bradley servos to seamlessly connect different levels of MagneMotion track.
In addition, DMC programmed Compact GuardLogix PLCs for each work cell to control its equipment and properly execute its testing step. All fifty line PLCs and three cell PLCs used PackML architecture, which standardized information between work cells to ensure all machines were functioning in sync with each other.
In total, this massive project included thousands of motors, hundreds of paths, hundreds of nodes, and over ten node controllers. With our MagneMotion experience and wide variety of expertise, DMC was able to provide Ginkgo with comprehensive PLC, SCADA, and application development solutions to process over 100,000 samples a day. DMC is proud to have been part of Ginkgo’s effort to expand COVID testing and help develop a sequencing facility that can be used in many different ways for years to come.
