  • the development of an autonomous Library Assistant service robot
    2008
    Co-Authors: Julie Behan
    Abstract:

    In modern society, service robots are becoming increasingly integrated into the lives of ordinary people. This is primarily due to the fact that the world is becoming an aged society (a society in which 10% of the population is over 60 years of age). Service robots may provide support to this increasing pool of aged individuals in a variety of forms, such as social interaction robots (Bruce et al., 2001; Breazeal 2002; Fong et al., 2003), task manipulation in rehabilitation robotics (Casals et al., 1993; Bolmsjo et al., 1995; Dario et al., 1995) and through assistive functionality such as nurse bots, tour guide robots etc (Evans 1994; Thrun et al., 2000; Graf et al., 2004). This chapter describes the development of an autonomous service robotic Assistant known as “LUCAS”: Limerick University Computerized Assistive System, whose functionality includes the assistance of individuals within a Library environment. The robot is described in this role through environment interaction, user interaction and integrated functionality. The robot acts as a guide for users within the Library to locate user specific textbooks. A complete autonomous system has been implemented, which allows for simple user interaction to initiate functionality and is described specifically in terms of its implemented localization system and its human–robot interaction system. When evaluating the overall success of a service robot, three important factors need to be considered: 1. A successful service robot must have complete autonomous capabilities. 2. It must initiate meaningful social interaction with the user and 3. It must be successful in its task. To address these issues, factors 1 and 3 are grouped together and described with respect to the localization algorithm implemented for the application. The goal of the proposed localization system is to implement a low cost accurate navigation system to be applied to a real world environment. Due to cost constraints, the sensors used were limited to odometry, sonar and monocular vision. The implementation of the three sensor models ensures that a two dimensional constraint is provided for the position of the robot as well as the orientation. The localization system described here implements a fused mixture of existing localization techniques, incorporating landmark based recognition, applied to a unique setting. In classical approaches to landmark based pose determination, two distinguished interrelated problems are identified. The first is the correspondence problem, which is concerned with finding pairs of corresponding landmark and image features. The

  • The development of an autonomous service robot. Implementation: “Lucas”—The Library Assistant robot
    Intelligent Service Robotics, 2008
    Co-Authors: Julie Behan, Derek T. O’keeffe
    Abstract:

    This paper describes an autonomous mobile device that was designed, developed and implemented as a Library Assistant robot. A complete autonomous system incorporating human–robot interaction has been developed and implemented within a real world environment. The robotic development is comprehensively described in terms of its localization systems, which incorporates simple image processing techniques fused with odometry and sonar data, which is validated through the use of an extended Kalman filter (EKF). The essential principles required for the development of a successful assistive robot are described and put into demonstration through a human–robot interaction application applied to the Library Assistant robot.

    Abstract:

    In modern society, robots are been designed to play an increasing role in the lives of ordinary people. Among the emerging areas in robotics is the field of service robots. This paper describes a mobile robotic Assistant, named 'LUCAS', Limerick University Computerised Assistive System that is currently been developed to assist individuals within a Library environment while also socially interacting with them. Human-Robot interaction is initiated through a 3-D animated character displayed on the robots onboard p.c. A continuous localisation process is described which relies on monocular vision and ultrasonic range readings. The process involves dividing the navigable space into localisation variant regions, and employ's methods of landmark feature extraction, vanishing point estimation and ultrasonic pattern detection to localise the robot within each region.

  • Survey of Staff and Organization of Private Secondary School Libraries in Ondo West Local Government Area of Ondo State

    Abstract:

    Introduction Effective and quality service delivery in the Library depends on the quality of staff. The ease with which users access and retrieve materials is organically linked to the quality of staff. In school libraries, teacher-librarians are saddled with the responsibilities of providing quality service and systematic organization of school Library resources. The importance of the teacher-librarian in the school Library cannot be over-emphasized. Even in most Nigerian public secondary school libraries, professionally-qualified Library staff or para-professionals are scarce. Alabi (2007) surveyed seven school libraries in Lagos and found that they are still being staffed by unqualified personnel. The objectives of this study are to: * Identify the number of staff in the Library, * Identify the qualifications of the Library staff, * Determine the extent of Library resources organization, * Identify the challenges confronting Library services, * Offer suggestions to identified problems. Literature Review Library resources without professionally qualified staff to organize them will not be of any use. In support of this, Onatola (2004), affirms that "there is need to have in every school a Teacher-Librarian, who shall be ready to effect and facilitate interactions between the teachers, learners, and the books". Onatola further states that "the Teacher -Librarian shall be directly responsible to the principal of the school for the day-to-day running of the Library." There are always staff specifications and qualifications for effective service delivery in any organization, private or public. The National Policy on Education (2004) recognizes the need for training librarians and Library Assistants. The policy is still on paper and yet to be implemented. On the number of staff to be employed in the school Library, Fayose (1995) outlines the requirement as follows: 1. School Librarians should be doubly qualified in teaching and librarianship. 2. A technician should have the knowledge of the management, production, and use of audiovisual materials 3. All schools with an enrolment of five hundred pupils/students should have a librarian, technician, and a Library Assistant. 4. Schools with lower enrolment can have a librarian and a Library Assistant. 5. Typists, cleaners, security men, and others who are needed besides those who are directly involved in Library work. 6. Some schools use volunteer members (students) as Library Assistants. Metzger (1992) supported the dual professional qualification for teacher-librarians. Through the systematic organization of resources in the Library by the teacher-librarian, the following services are offered to users of the Library: 1. Loans 2. Book-box service 3. Bibliographic services 4. Inter-Library loans 5. Repackaging information. 6. Reprographic services 7. Reference services 8. Exhibition and displays 9. Hobbies and societies 10. Teaching Library use skills 11. Teaching study skills (Fayose, 2002). The services listed by Fayose are crucial to Nigeria educational development. Despite the services offered by the school Library, there are still problems. According to Fayose (2003), government has always paid lip service to school Library development, but many policies remain on paper and are never implemented. Dike (1993) posits that, "funds that could be used to develop school Library services were more than expended on crash programmes." A second reason is perhaps that there was insufficient demand for school libraries. Moreover, most teacher-librarians had no exposure to librarianship before appointment and no training, even years after appointment (Ogunleye, 1988). A survey was adopted for this research. …
