Technology Data-centric system architecture addresses IIoT challenges Connectivity is key to the future of industries including robotics and, in time, the IIoT will be as pervasive as the regular Internet is today. Common reference architectures and connectivity standards, such as the Data Distribution Service (DDS), are expected to rapidly replace custom connectivity solutions across systems. WHAT DO REMOTELY-CONTROLLED Mars exploration robots and minimally invasive robotic surgery (MIRS) have in common? In many ways the technology and communication requirements for the two applications could not be more different. But in both cases, developers are benefiting from a common datacentric communications system architecture that helps abstract complexity and reduce the costs of connecting components, devices and systems across the Industrial Internet of Things (IIoT). This article examines some of the challenges of designing modern robotic systems. It details the real-life lessons derived from NASA’s Human Robotic Systems project, the European Space Agency (ESA) Telerobotics and Haptics Lab, and the development work being done at MIRO Lab, an advanced robotic assistance research laboratory at the Robotics and Mechatronics Center within the German Aerospace Center (DLR). Developers and system architects must address extreme communications challenges- including reliability, performance and scalability-when building robust systems for these and other telerobotics applications. RTI worked closely with NASA and the MIRO lab on their implementation of the Data Distribution Service (DDS) communication standard to help address the challenges they were facing. Discussions center on key DDS contributions including decentralized architecture, real-time Quality of Service (QoS) and security capabilities. Communication challenges The most disruptive change in almost every industry, including robotics, is upon us. The era of smart machines is heralding the transition from a landscape of unconnected local infrastructure to one built on the IIoT where devices, machines and complete systems will be will be integrated into fully functioning systems of systems, and connected to the cloud. Particularly for robotic systems, the real-time model of the environment will no 36 industrial ethernet book 2.2018 SOURCE: RTI Peer-To-Peer Plug & Play Layered Databus Architecture.
