Name service redundancy in robot technology middleware

Robot systems are comprised of several systems working together as a whole. The concrete job of a robotic system determines the elements required by the given task. These reusable and fungible elements can be implemented as robot components which use each other via well-defined interfaces. The behavior of the components and the manner of interaction among them can be standardized by the Robotic Technology Component (RTC) specification. The main component of an RTC system is a central process called naming service, which stores the data about all the other available components. The goal of this paper is to introduce a novel robust RTC system concept, which can handle more naming services to be tolerant for naming services failures.
