Industry 4.0 Asset Administration Shell (AAS): Interoperable Skill-Based Service-Robots

This paper describes our use of Industry 4.0 Asset Administration Shells (AASs) in the context of service robots. We use AASs with software components of service robots and with complete service robot systems. The AAS for a software component serves as a standardized digital data sheet. It helps sysem builders at design time in finding and selecting software components that match system-level requirements of the systems to be built. The AAS for a system comprises a data sheet for the system and furthermore collects at runtime operational data and it allows for skill-level commanding of the service robot. AASs are generated and filled as part of our model-driven development and composition workflow for service robotics. AASs can serve as a key enabler for a standardized integration and interaction with service robots.
