An algorithm was proposed intending for external view image processing of FRP panel in visual inspection process. In the proposed algorithm, three kinds of inspection information such as location, size and level of defects are treated for clustering image data. The proposed algorithm enables one to process the dynamic sequential images with small facility and to obtain a reasonable efficiency of visual inspection. When the algorithm proposed by the authors was included, instead of a visual inspection process by a human being, it is expected that the productivity will be further improved and the human being, machine and computer will be cooperated respectively. Some numerical studies for visual inspection of FRP panel shows that the performance of the proposed algorithm is similar to that of expert inspector.

Coordinated control technologies have been developed for multi-robot collaboration in a common environment remotely controlled from multiple operators physically at a distance from each other. To verify the validity of the proposed approaches, we built a test bed and conducted a series of experiments, where we learned the effect of communication delay over the network on the performance of telerobots. This paper discusses the use of an online predictive simulator in the multi-operator-multi-robot (MOMR) tele-collaborative system to cope with the operator's delay visual perception over the network with time delay. In the test bed, each operator controls his/her master device to control two slave robots to cooperate in a task and detect a priori the possibility of collision in the graphics simulator that runs in near real-time. We demonstrate various tasks performed by two slave robots and two operators through LAN subjected to the simulated delays, and evaluate the use of the predictive simulator in MOMR tele-collaboration.

Describes the mental model for perceived load on low back using a cognitive approach in addition to biomechanical and physiological approaches. In the results of experiments, it is clarified that poor cognitive ability of low back strength in the mental model reproducing the same strength is relevant to the low back pain. The studies show that cognitive ability of low back strength in the mental model could be improved by informing the content of working posture previously.

The paper concerns an agent-based human-robot interface via the Internet. A user client and an embedded software are viewed as agents with limited computational and communication resources. To facilitate the communication between the real-time embedded agents and the user interface agents via the communication channel of uncertain quality the proxy agent is proposed as a mediator. The functions assigned to the proxy agent target reduction of inter-agent communication load and minimization of computational resources taken by the embedded agents and user interface agents for communication-related tasks. An XML-based language, RoboML, is designed to serve as a common language for robot programming, agent communication and knowledge representation. The human-robot interface software prototype is developed for an autonomous guided vehicle to evaluate the proposed techniques.

This paper proposes a new model of 4-DOF mixed serial and parallel robot for living assistance, which combines stable structure and high rigidity of the parallel mechanism and wide workspace of the serial mechanism organically. The rotary DOF with 3 rotary axes intersecting one point enables the end effector to change its location, by as much as 360/spl deg/. One linear DOF can adjust the height of the end effector. The model can be applied for nursing and recuperation, if other devices be connected to it, or can be made into a medical operating platform.

We propose dual views of Cartesian and configuration space as a teleoperation support system. To overcome a transmission delay between master and slave robots. We use a 3D graphics display besides a master robot, which virtually represents a slave robot and its environment (a slave site). In this system, an operator picks up a sequence of good motions of a slave robot while watching the 3D graphics display. In this case, we discuss what kinds of graphics images are needed for an operator to select each robot motion adequately. In this paper, we prepare not only Cartesian space of a slave site but also its configuration space as graphics images. Moreover, the configuration space is expressed by not only a 3D whole space but also its 2D sliced image. Finally, usefulness and efficiency of the visual support system are ascertained in some experiments by several test subjects.

The study was designed to measure and evaluate mental fatigue induced during VDT tasks using the P300 component of the event-related potential. The experimental task induced mentally and physically fatigued states to each subject from the viewpoints of performance decrement and subjective feeling of fatigue. In accordance with this result, the P300 amplitude tended to decrease after the experimental task. The P300 latency increased after the experimental task. The results indicated that the appearance of fatigue was reflected in the two P300 components, that is, the P300 amplitude and the P300 latency. The prolonged P300 latency that indicated the delayed cognitive information processing and the decreased P300 amplitude that was related to the decreased activity of cognitive information processing were found to be effective measures of mental fatigue.

When a two-joint link mechanism was installed with an antagonistic pair of bi-articular actuators in addition to antagonistic pairs of mono-articular actuators the two-joint link mechanism could demonstrate perfect human-like control properties at the endpoint. First, only a single command signal informing the target point could control any desired output force direction at the endpoint via a simple spinal level neural network. Second the existence of three antagonistic pairs of actuators made it possible to control three parameters of a viscoelastic ellipse exerted at the endpoint independently, and consequently to induce coincidence of trajectory and output force exerted at the endpoint. Thus, the mechanism could lead smooth, rapid and precise movements without use of positional feedback signal from the endpoint, i.e. open loop control.

This paper reveals the chaotic properties of the voluntary single arm and two arms movements in various conditions based on the movement frequency and movement modes (single arm mode, in-phase mode and anti-phase mode). The chaotic analysis of rhythmic forearm movement were performed, and it was confirmed that the chaotic characteristics represented by the correlation dimension and the largest Lyapunov exponents were included in the rhythmic forearm movements. Furthermore, it was clarified that there existed the difference in the values of the Lyapunov exponents and fractal dimensions between right-left forearms and consequently the left forearm movements was more complex than the right forearm movements.

We present the simulator for the interpersonal relation by using Egogram. The Egogram consists of 5 categories including critical parents, nurturing parents, adult, free child and adapted child. It indicates personality and is used for counselling by analyzing the magnitudes of the 5 categories and also for estimating the interpersonal relation. By comparing results obtained from our simulator to the ones from the real clinical counselling in terms of the interpersonal relations, we confirm the adequacy of our simulator.
