  • Distributed Telerobotics System Based on Common object request broker Architecture
    Journal of Intelligent and Robotic Systems, 2020
    Co-Authors: Yasushi Hada, K. Takase
    Abstract:

    This paper proposes using CORBA as communication architecture to integrate network-distributed software and robotic systems in support systems for the aged or disabled. The proposed method keeps system costs low and expands availability. Its high scaling and inter-operating ability allows clients and server objects that are written in different languages, run in different operating systems, and connected to different networks to inter-operate. It also enables the system to be extended and integrated with other technologies and applications distributed over the Internet. Based on CORBA, we developed hardware base including a robot arm and an omnidirectional mobile robot and application servers including a task-level robot arm control server, live feedback image server, mobile robot control server and iGPS server. By remotely controlling mobile robot to cooperate with the robot arm, the caregivers or family member can use the developed system for some basic services to the aged or disabled.

  • ICARCV - Internet distributed robotic systems integration using Common object request broker Architecture
    7th International Conference on Control Automation Robotics and Vision 2002. ICARCV 2002., 2002
    Co-Authors: Yasushi Hada, K. Takase
    Abstract:

    This paper proposes a novel method to integrate Internet distributed robotic systems using Common object request broker Architecture for implementing telecare robotic system to aid the aged or disabled. The proposed method makes system have low cost and wide availability, high scaling and inter-operating ability to allow the clients and server objects, written in different languages, run in different operating system, and connected in different network to inter-operate. It also makes it easier for system to be extended and integrated with the other technologies and applications distributed over the Internet. Using CORBA as a communication architecture, we developed hardware base, Web user management server, task-level robot arm control server, live image feedback server, mobile robot control server and iGPS server, which can provide some basic care services to aid the aged and disabled.

  • An Internet robotic system based common object request broker architecture
    Proceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2001
    Co-Authors: K. Takase
    Abstract:

    Because the elderly population is growing while the number of people to take care of them is declining, we propose an Internet telerobotic system to assist the aged or disabled in their homes when their caregivers are away. We analyze typical teleoperation robotic systems and design an Internet telerobotic system using CORBA . We detail the system's features, architecture, and implementation. The proposed system gives users the ability to control the robotic system remotely by an intuitive user interface. The client can transparently invoke methods on the application servers across the network without knowing where the application servers are located, what programming language the application is written in, or what operating system is being used. This is because, in developing and implementing the system, CORBA for the distributed, object-oriented applications was used.

  • CORBA-based speech-to-speech translation system
    2001 IEEE Workshop on Automatic Speech Recognition and Understanding, ASRU 2001 - Conference Proceedings, 2001
    Co-Authors: Rainer Gruhn, Atsushi Nishino, Kazuto Takashima, Satoshi Nakamura
    Abstract:

    © 2001 IEEE.We describe the new implementation of a speech-to-speech translation system at ATR Spoken Language Translation Research Laboratories (SLT). We use the architecture standard CORBA (Common object request broker Architecture) to interface between a speech recognizer, translation system and TTS engine. Various input types are supported, including close-talking microphone and telephony hardware.

  • ACSAC - Security for the Common object request broker Architecture (CORBA)
    Tenth Annual Computer Security Applications Conference, 1994
    Co-Authors: S. Chapin, W. Herndon, L. Notargiacomo, M. Katz, T. Mowbray
    Abstract:

    Over the last several years, there has been an emphasis on distributed client/server computing in business as well as government. A useful means of achieving this capability is through the use of object technology. Distributed object systems offer many benefits, such as downsizing and right sizing, resulting in a trend toward small, modular, commercial or government off-the-shelf components as a means of system development. Distributed object management standards, such as the Common object request broker Architecture (CORBA) specification are aiding the integration process. One area of distributed object systems that has received little attention to date is security. Security is a difficult problem in traditional software systems, and adding distribution and use of object-oriented techniques just increases the complexity of the problem. The object Management Group (OMG) is beginning to solicit proposals from vendors for handling security in a distributed object environment. This paper gives an overview of distributed object management and standards being specified by the OMG. It applies traditional security engineering analysis to CORBA and highlights some of the security function interdependencies among CORBA components. >

  • The design of the TAO real-time object request broker
    Computer Communications, 2002
    Co-Authors: Douglas C Schmidt, David L. Levine, Sumedh Mungee
    Abstract:

    Many real-time application domains can benefit from flexible and open distributed architectures, such as those defined by the CORBA specification. CORBA is an architecture for distributed object computing being standardized by the OMG. Although CORBA is well-suited for conventional request/response applications, CORBA implementations are not yet suited for real-time applications due to the lack of key quality of service (QoS) features and performance optimizations. This paper makes three contributions to the design of real-time CORBA systems. First, the paper describes the design of TAO, which is out high-performance, real-time CORBA 2.0-compliant implementation that runs on a range of OS platforms with real-time features including VxWorks. Chorus, Solaris 2.x, and Windows NT. Second, it presents TAO's real-time scheduling service that can provide QoS guarantees for deterministic real-time CORBA applications. Finally, the paper presents performance measurements that demonstrate the effects of priority inversion and non-determinism in conventional CORBA implementations and how these hazards are avoided in TAO. © 1998 Published by Elsevier Science B.V.

  • Scalability Issues in COMA-based Systems
    2020
    Co-Authors: Steve Vinoski
    Abstract:

    This tutorial addresses how both the object Management Group (OMG) specifications and the implementation choices made by middleware providers and application developers affect Common object request broker Architecture (CORBA) application scalability. We will cover a range of scalability issues, starting with object request broker (ORB) intemals and working outward to full-scale applications, addressing issues such as connection management, Portable object Adapter (POA) scalability features, multithreading, object lifecycle issues, object location, system configuration, maintenance, and management, and common application architectures. This tutorial is not language-centric and is useful to developers using Java, C++, or any other language to develop CORBAbased applications.
