8、 The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying tec
9、hnical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which
10、, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and I
11、EC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to e
12、nsure, e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words do
13、es not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerni

20、bot platform that supports ubiquitous sensor network applications and services 1 Scope The objective of this Recommendation is to define a ubiquitous network robot platform, and to identify its requirements and functional model. The use of standard interfaces for the ubiquitous network robot platfor
21、m will ensure network robot service reusability, portability across several network robot services, and network accessibility and interoperability by the ubiquitous sensor network (USN). The scope of this Recommendation includes: the concept of ubiquitous network robot platform; requirements of the
22、ubiquitous network robot platform; functional model of the ubiquitous network robot platform. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

29、s Recommendation defines the following terms: 3.2.1 robot: A device with a processing unit often accompanied by sensors and actuators that can work with real-world phenomena and entities. Robots can be roughly classified into the following three types: visible-type robot, virtual-type robot and unco
30、nscious-type robot. 3.2.2 ubiquitous network robot platform: Middleware that enables applications to perform services continuously by combining multiple robotic devices effectively across multiple areas. 3.2.3 unconscious-type robot: A type of robot that mainly senses real-world phenomena and proces
31、ses measurement results into high-level abstractions. An example of this type of robot is a camera equipped with a processing unit used for detecting people. Unconscious-type robots are often embedded in environments such as roads, towns or rooms, or are hidden in clothes or accessories. 3.2.4 virtu
32、al-type robot: A type of robot that mainly processes and utilizes information via a network. Smartphones are examples of this type of robot. Virtual-type robots typically interact with people through audio and visual modalities. 3.2.5 visible-type robot: A type of robot that can be seen and which ca
33、n take one of several forms such as a humanoid, a pet or a stuffed animal. Visible-type robots interact with people in a combination of verbal and nonverbal modalities such as through a conversation augmented by gestures. 4 Abbreviations and acronyms This Recommendation uses the following abbreviati

ITU-T F.747.3 (03/2013) 3 6 Overview of UNR-PF in terms of USN applications and services 6.1 General overview of UNR-PF Demands for assistance robots are quickly emerging with the increase in elderly population. In recent decades,
36、 researchers have been focusing on constructing robots that can interactively support daily human activities. As the structure and functionality of robots grow large and complicated, constructing robots now requires more time, cost and effort. As with traditional software engineering, developers hav
37、e started to seek modularity and reusability of basic functional components, which has led to research and development of common libraries and middleware. Reusable and modular components allow developers to utilize existing functional modules in combination with their own software and to rapidly dev
38、elop working robots. This modularized development process has accelerated the development of stand-alone robots as well as individual functional components. At the same time, however, variations in both hardware and software have decreased the reusability of robotic applications. Another approach to
39、 enhance capabilities of robots is the concept called network robot system (NRS) or networked robots b-Sanfeliu2008. The main goal of NRS was to integrate various types of devices such as robots, sensor networks and smartphones, so that the whole system could act as an integrated system with enhance
40、d capabilities that cannot be attained by a single robot or multiple uniform robots. Since its introduction in 2002, many research projects have been carried out accompanied with real-world field experiments. These have successfully shown that the concept is effective (b-Jung2007, b-Nakamura2008, b-
41、Tezuka2006, b-Sanfeliu2010, b-Shiomi2011 and b-Salvini2011). However, customers need robots to support them in a much wider range of daily activities. Robots for individual household tasks such as cleaning floors or folding laundry are not sufficient. Support for the elderly and disabled in a variet
42、y of daily activities is in great demand. Such support requires robots to accompany people to many different places (e.g., homes, shopping malls, hospitals) and to assist people for various activities (e.g., checking health, showing routes, carrying luggage) in ways that differ depending on place an
43、d the physical demands of an individual (e.g., wheelchair user). At the same time, these sequences of activities shall be well integrated to provide comfortable and seamless support throughout our daily lives. Existing robotic systems cannot yet provide such continuous support in various aspects of
44、our daily lives. Although they have had success in enriching capabilities of individual robotic applications, a general framework is missing for adapting behaviours of robots and composing them to form an integrated sequence of applications. Similar concepts can be seen in computer systems, such as
45、service oriented architecture (SOA). SOA provides design principles for constructing large-scale information systems and has been adopted in various middleware stacks, especially in web service systems. In combination with the concepts of grid or cloud computing systems, many commercial services wit
46、h high dependability are available today. However, these concepts are not sufficient for robotic systems. The major difference between information systems and robotic systems is where the applications reside. Information system applications reside in cyberspace using information terminals such as pe
47、rsonal computers or mobile phones. This is especially clear for web-based systems where applications run through web browsers. Based on the information shown on the screen, users perform actions such as business procedures, travel and cooking. Thus, the actual work in the physical world is left to t
48、he customers. This is where the robotic systems with sensor networks start. Robotic systems need to consider various factors in real-world environments, including physical abilities and limitations of both customers and devices. Moreover, as stated previously, a variety of different devices need to
49、be integrated to realize continuous robotic support in our daily lives. 4 Rec. ITU-T F.747.3 (03/2013) As such, one needs to focus on different kinds of “ubiquity“, not just for location but also for various applications and ways of providing each service on the basis of customer attributes, as well as inter-application and inter-location continuity. As the complexity of robotic devices is much higher than that of traditional information systems, abstract, common access methods need to be provided for application programme
