Blockchain is a disruptive technology that is normally used within financial
applications, however it can be very beneficial also in certain robotic
contexts, such as when an immutable register of events is required. Among the
several properties of Blockchain that can be useful within robotic
environments, we find not just immutability but also decentralization of the
data, irreversibility, accessibility and non-repudiation. In this paper, we
propose an architecture that uses blockchain as a ledger and smart-contract
technology for robotic control by using external parties, Oracles, to process
data. We show how to register events in a secure way, how it is possible to use
smart-contracts to control robots and how to interface with external Artificial
Intelligence algorithms for image analysis. The proposed architecture is
modular and can be used in multiple contexts such as in manufacturing, network
control, robot control, and others, since it is easy to integrate, adapt,
maintain and extend to new domains.info:eu-repo/semantics/submittedVersio
