1A2-K07 Robot System for Tele-Ultrasound Imaging Diagnosis

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) (2007)

Takahiro Abe Hiroyuki Koyama Takashi Komeda Shinichirou Yamamoto

We are developing the robot system for tele-ultrasound imaging diagnosis. This system consists of the master-slave robot system in order to use probes of the ultrasound diagnostic equipment for the telemedicine. This paper reports about a development of the slave robot and remote control the slave robot.

2A1-A28 The development of endoscope operation training simulator

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) (2006)

Satoshi YONEYAMA Hiroyuki Koyama Takashi Komeda Shinichirou Yamamoto

Endoscope operation need a doctor high technically. Therefore there are many medical accidents. In late years demand of an endoscope operations rises. From this, a doctor has to take appropriate training. Training observes only movement of the lecturer side , but minute movement of forceps is hard to understand it. By this study, the master robot which an experience-rich doctor operates reappear movement of forceps of a slave robot of the student side. I describe development of master robot mechanism in a slave system by this report.

Non-invasive Measurement of Human Skin by Confocal Laser Scanning Microscope

The proceedings of the JSME annual meeting (2003)

Kenji Atami Sachie Matsumoto Shinichirou Yamamoto Takashi Komeda Hiroyuki Koyama

Confocal laser scanning microscope can observe cell form of the human skin in vivo, i.e.; horny layer, granular layer, prickle layer, basal layer and papillary dermis. The purpose of this study was to analyze quantitatively the internal structure of human skin in various forearm sites, and to compare the difference between healthy and atopic dermatitis subjects. In results, the number and volume of papillary dermis were significantly greater in atopic dermatitis subjects as compared to that of healthy subjects. This suggests that the internal skin structure of atopic dermatitis might be altered. On the other hand, the number of papillary dermis was greater in lateral site of forearm as compared to that medial site. This indicates that it might be caused by the ultraviolet effect.

Library evolution for reliable software

Noritoshi Atsumi Shoji Yuen Kiyoshi Agusa Shinichirou Yamamoto

This paper shows a methodology to evolve a library of functions to be with common patterns of usage, called idioms. In source programs written in C, it is commonly seen that library functions are combined in a certain pattern since functionalities required in application software are more abstract than those of the library functions. This means that using appropriate idioms for the purpose is one of the key issues in implementing functionalities of the software. Investigating idioms in the existing elaborate software in terms of control and data dependencies of library function-calls, it is observed that "good" idioms contribute to the reliability in developing and maintaining software. Based on this idea, we extract idioms from the existing open-source software in the form of FCDGs (Function Call Dependency Graphs). By categorising those idioms as a database of FCDG patterns, we propose evolved libraries where each library function is accompanied by the typical reliable patterns of usage. By exploiting an evolved library, we show how effectively potential defects that may lead to unexpected behaviour are resolved by checking the conformance to our idioms.

1A1-J05 Development of a Grip Aid System : For Grasp Assistance and Rehabilitation

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) (2007)

Kie IWATA Hiroyuki Koyama Shinichirou Yamamoto Takashi Komeda

We have been developing a Grip Aid System for aged persons who have a weak grip power. The device is required to be able adjust load setting for each patients and be small and light weight. We focused on MP joint and PIP joint angle of hand to assist. To develop small and light weight device, we are tackling to assist both MP and PIP joint with one actuator. Therefore the angular relationship of MP and PIP joint is estimated. In this paper, we developed a Grid Aid System with new mechanism using one pneumatic actuator to assist MP joint.

Evaluation of the Effects of Geometrical Changes in Prosthetic Socket Towards Transfemoral Residuum via Finite Element Method

Mohd Syahmi Jamaludin Akihiko Hanafusa Shinichirou Yamamoto Yukio Agarie Hiroshi Otsuka

This study investigated the effect of prosthetic socket shape on the transfemoral residuum by using the finite element method. The effect of two Ischial-ramal-containment sockets (MCCT and UCLA) was evaluated during the donning process by predicting the qualitative measurement in a simulation. The simulation, mimicking the actual donning process, was done by creating a finite element model of residuum and socket based on the MRI image of subject`s residuum with and without socket. The change of contact surface pressure and geometry of the residuum were observed in the cross-section area along 170 mm from the distal end. A high correlation coefficient of pressure was recorded between experiment and simulation (0.976) with a mean error of 4.93% in UCLA case. The simulation results also showed that the maximum pressure of residuum in MCCT socket was higher than that in UCLA. The highest changes of soft tissue area occurred at the edge of both sockets-6.03% and 6.06% of increment for MCCT and UCLA respectively. The existence of pressure at the measuring point changed the residuum geometry, increasing 11.32% and 7.24% residuum length for UCLA and MCCT respectively. Our result will help the engineer and prosthetist to understand the residuum behavior during donning process. Moreover, it may help in modifying the socket shape to offer better comfort to the subject.
