  The concept of federation in 5G and NFV networks aims to provide
orchestration of services across multiple administrative domains. Edge
robotics, as a field of robotics, implements the robot control on the network
edge by relying on low-latency and reliable access connectivity. In this paper,
we propose a solution that enables Edge robotics service to expand its service
footprint or access coverage over multiple administrative domains. We propose
application of Distributed ledger technologies (DLTs) for the federation
procedures to enable private, secure and trusty interactions between
undisclosed administrative domains. The solution is applied on a real-case Edge
robotics experimental scenario. The results show that it takes around 19
seconds to deploy & federate a Edge robotics service in an external/anonymous
domain without any service down-time.
