Evolution of Mobile Robotic Manufacturing Systems at Spirit
AeroSystems 2023-01-0996
Efforts toward the mechanization of aircraft manufacturing began as a divided
focus between devices like power tools that augment human worker capability and
purpose-designed, “monument” automation. While both have benefits and
limitations, the capability of modern industrial robots has grown to the point
of being able to effectively fill the capability gap between them, offering a
third option in the mechanization toolbox. Moreover, increasing computer
processing power continues to enable more advanced approaches to perception to
inform task planning and execution. Higher performance robots supplemented with
greater ability to adapt to various conditions and scenarios have also led to
the ability to operate reliably and safely outside traditional
fixed-installation, caged work cells. This in turn has made it feasible for
robot systems to work in ever more complex environments and applications,
including the world of aircraft assembly with its numerous challenges like
workpiece scale, precision issues due to compounding tolerance stack-ups, and
confined and often crowded spaces – including the potential for interaction with
human workers. Mobile industrial robot systems are becoming more common
throughout the aerospace industry and the most popular use case is still
drilling and fastening. Spirit AeroSystems has been at the forefront of this
trend since the early 2000’s in terms of system architecture and configuration,
technology testing and maturation, and deployment into production use cases. In
conjunction with a number of supplier partners, Spirit has nearly 20 years’
worth of history and lessons learned regarding drilling and fastening processes
performed by mobile industrial robotic systems including several new systems
across multiple programs and aerostructure configurations.
