However, there are some issues…
• Robotic automation not designed for most accuracycritical, high-force, interactive applications
– Accuracy, stiffness, cognitive capability requires fundamental design
changes
– Perceived as relatively low-volume opportunity by OEMs
– Deficiencies addressed at system integrator level (customization);
unexpectedly high turnkey system cost
– Diverse landscape of integrators can be confusing
• 2nd tier measures to improve performance result in
cost, reliability issues
• Myriad safety, process integration inefficiencies
• Complexity, idiosyncrasies of proprietary controllers
• Fear of losing jobs to automation
How do we address these issues?
1. Use what’s already working…


Implement automation where current technology allows
Gain familiarity, expertise
2. Establish internal automation infrastructure



Skilled trades for programming, operating, maintaining
Develop guidelines, standards for automation utilization
Implement control, data network architectures
3. Adapt engineering designs, manufacturing
processes


Design for Automated Manufacturing (DFAM) crucial
Greenfield scenarios vs. existing process improvements
How do we address these issues?
4. Collaborate with each other




SME Aerospace Automation Consortium
SAE Aerospace Manufacturing & Automated Fastening
Midwest Robotics Initiatives Council
NSF Roadmap for US Robotics
5. Partner with OEMs, integrators, researchers




Educating OEMs about process requirements, market
potential will lead to new capabilities, designs
Some progressive integrators already addressing issues
Research institutions provide opportunities for shared
resources, short-term results
Use collaborative environment to garner government
resources
