ABSTRACT: This paper proposes a scheme to recover the state of peripheral devices in non-volatile main memory systems so that the system resumes its execution after an unpredictable power failure. Our scheme is software-based approach and accomplishes the recoverable system without complex hardware equipments. First, the requirements for maintaining consistency are discussed based on the concepts of distributed message-passing systems. Next, the application to a device driver is illustrated using an example. Experiments with UART and network devices showed that the system restarted properly after a power failure, and that system performance was barely decreased.

ABSTRACT: In the near future, robots used by human-like personal computers
will appear in office or at home. In this paper, we call these robots
personal robots. A personal robot can be thought as a small autonomous
mobile robot. First, we discuss a user interface design for personal
robots in the face-to-face situation. Second, we consider the features
of personal robots and their environments, and propose a new user
interface concept for a personal robot an active interface. To show the
effectiveness of the active interface, we design and implement a speech
dialogue system called Chaser for human-robot interaction based on the
active interface

ABSTRACT: In order to support the cooperative work of human, the research of
computer-supported cooperative work has been evolved, and many groupware
have also been developed. In the cooperative work of human, the task may
involve in the transportation of physical entities that conventional
groupware can not handle. The authors propose an interface architecture
for the transportation of physical entities in distributed environments
by utilizing mobile robots. In this paper, they propose a multi-agent
model that can represent human-robot interaction in distributed
environments by extending the multi-agent model of the groupware toolkit
Michele developed by the authors. The interface system based on the
extended multi-agent model has been implemented by utilizing the
autonomous mobile robot Einstein developed in the laboratory. The
multi-agent model, the agent description language, implementation issues
and applications for office automation are described

ABSTRACT: Discusses about the interface for personal robot systems that are
not supported by social authority. The paper consists of two parts. The
paper describes HuRIS, a human-robot interactive system for supporting
human-robot and human-human communication. HuRIS aims to be acting as an
agent of a user. The robot of HuRIS can accept voice commands by its
voice recognizer, and can reply via its simple natural language
processing system and voice synthesizer. The robot has the ability of
asking a human for help by using the voice synthesizer when it is
trapped in failure. However, the humans around the robot do not always
accept its commissions. The necessary condition that a human accepts a
request of a robot is not known. The authors describe experiments on
robot's commission in some detail. In Experiment 1, they show that a
request of a robot supported by no social authority is not accepted by a
human. In Experiment 2, they show that by using the HuRIS's interface,
the performance of the subjects is generally similar for human and robot
commission. The paper concludes that the interface for HuRIS as a
personal mobile robot system is effective

ABSTRACT: One of the important factors required to realize personal robots
is mutual cooperation between humans and robots. To support human
cooperative work based on asynchronous communication, the authors had
developed a groupware toolkit called Michele. They propose a multi-agent
interface architecture called RT-Michele. A prototype of RT-Michele was
implemented, and autonomous mobile robots were developed. RT-Michele was
applied to office automation, where it provided not only asynchronous
communication, but also real-time interactive communication for
cooperative work among humans and mobile robots
