- BACKGROUND AND AIMS: Recent studies on endoscopic submucosal dissection have aimed to reduce the difficulty of the procedure by using multi-degrees-of-freedom articulating devices. In this study, we evaluated the usefulness of adding three-dimensional (3D) video imaging into simulated endoscopic submucosal dissection tasks using multi-degrees-of-freedom devices. METHODS: We designed an endoscopic platform with a 3D camera and two multi-degrees-of-freedom devices. Four ex vivo bench tasks were created, and a crossover study comparing 2D and 3D conditions was conducted on 15 volunteers. In each task, performance such as procedure time and accuracy were objectively evaluated. Additionally, a comprehensive visual analogue scale questionnaire was conducted. RESULTS: In the tasks simulating submucosal flap grasping, marking, and full-area incision, the use of 3D imaging significantly improved the speed and accuracy of the multi-degrees-of-freedom device manipulation (p < .01). No significant differences were observed in the task that simulated the dissection procedure. Furthermore, it appears that the accuracy of recognizing curved surfaces may be reduced in the 3D environment. Operators reported subjective increases in recognizability and operability with the 3D camera, along with an increase in asthenopia (p < .01). CONCLUSIONS: 3D vision improves the technical accuracy of certain simulated multi-degrees-of-freedom endoscopic submucosal dissection tasks and subjectively improved operating conditions, at the cost of increased eye strain.Jan. 2024, Asian journal of endoscopic surgery, 17(1) (1), e13275, English, Domestic magazineScientific journal

- Minimally invasive surgery (MIS) is a viable alternative to general surgery with distinct advantages. Robotically assisted MIS, has been demonstrated to achieve higher accuracy and repeatability in comparison with those of manual procedures. Despite these advantages, owing to the nature of some surgical procedures in which dexterous tissue manipulations in deep narrow areas of the human body are necessary, there is a need for further miniaturized tools with smaller bending radii. To cater to this requirement, this study proposes a new compliant mechanism based surgical robotic forceps. It can generate four degrees of freedom at the tip of the forceps including two bending motions in two perpendicular axes, grasping and rotation. A better combination of the stress distribution through the elastic material, grasping force, and range of motion was determined based on a series of finite element analyses. In addition, the manufactured prototype underwent a series of laboratory experiments to evaluate its effectiveness. Details of the mechanism, finite element analysis, prototype implementation, and evaluations are presented in this paper.2023, Advanced Robotics, 37(4) (4), 270 - 280Scientific journal

- Gastrointestinal cancer, when detected early, is treated by accessing the lesion through the natural orifice using flexible endoscopes. However, the limited degree-of-freedom (DOF) of conventional treatment devices and the narrow surgical view through the endoscope demand advanced techniques. In contrast, multi-DOF forceps systems are an excellent alternative; however, these systems often involve high fabrication costs because they require a large number of micro-parts. To solve this problem, we designed compact multi-DOF endoluminal forceps with a monolithic structure comprising compliant hinges. To allow an efficient stress dispersion at the base end when the hinge bends, we proposed a novel design method to obtain the hinge parameters using the beam of uniform strength theory. This method does not involve a high computational cost. The results show that the improved design with a variable hinge thickness can reduce the maximum bending stress, dispersing the stress in a larger area than that of the previous design considering a constant thickness of the hinge. Moreover, the experiments conducted in a prototype confirm that the radius of the curvature was significantly improved. The proposed method could aid in designing other continuum robots relying on compliant hinges.MDPI AG, Feb. 2022, Applied Sciences, 12(5) (5), 2480 - 2480Scientific journal

- Early-stage gastrointestinal cancer is often treated by endoscopic submucosal dissection (ESD) using a flexible endoscope. Compared with conventional percutaneous surgery, ESD is much less invasive and provides a high quality of life for the patient because it does not require a skin incision, and the organ is preserved. However, the operator must be highly skilled because ESD requires using a flexible endoscope with energy devices, which have limited degrees of freedom. To facilitate easier manipulation of these flexible devices, we developed a surgical robot comprising a flexible endoscope and two articulating instruments. The robotic system is based on a conventional flexible endoscope, and an extrapolated motor unit moves the endoscope in all its degrees of freedom. The instruments are thin enough to allow insertion of two instruments into the endoscope channel, and each instrument has a bending section that allows for up–down, right–left, and forward–backward motion. In this study, we performed anLead, American Association for the Advancement of Science (AAAS), Dec. 2020, Cyborg and Bionic Systems, 2020, 1 - 9, English
ex vivo feasibility evaluation using the proposed robotic system for ESD in a porcine stomach. The procedure was successfully performed by five novice operators without complications. Our findings demonstrated the feasibility of the proposed robotic system and, furthermore, suggest that even operators with limited experience can use this system to perform ESD.[Refereed]Scientific journal - Aug. 2020, IEEE Robotics and Automation Letters, 5(4) (4), English, International magazineSelf-Propelled Colonoscopy Robot using Flexible Paddles[Refereed]
- The mechanism underlying tissue fusion mediated by laser irradiation remains unclear. We clarify the mechanisms underlying laser-mediated tissue fusion using a novel model. Microscopic examinations of morphological changes within the adventitia of a bovine carotid artery and a collagen sheet prepared from bovine dermis showed collagen fibril bundle loosening and collagen fibre swelling following heating at 46 °C. An incised bovine carotid artery covered with a collagen sheet to which pressure and laser heat of 40 °C-52 °C were applied created a structure that was pressure resistant to >300 mmHg. Microscopic analyses of the irradiation site showed collagen fibril interdigitation. Hence, low-temperature laser-mediated tissue fusion causes collagen fibril bundles to loosen and swell, and crimping causes the fibres to intertwine. As the temperature declines, the loosened and swollen fibrils and fibres tighten, and collagen fibre interdigitation is completed. This technology could be applied to fuse tissues during surgery.Jun. 2019, Scientific reports, 9(1) (1), 9383 - 9383, English, International magazine[Refereed]Scientific journal
- Minimally Invasive Surgery (MIS) is one of the most successful applications of surgical robots. Although the introduction of robotic technology has brought a number of benefits, further advancements in MIS are limited by the size and bending radius of instruments. In this paper, we present a compliant four degree-of-freedom manipulator that consists of elastic elements with partly thinner structures. The proposed mechanism allows the elastic element to deform locally, thus minimizing its bending radius while the low number of mechanical parts greatly contributes to its compactness. This paper describes the design strategy, optimization method using FEA, prototype implementation, and evaluations. The evaluations reveal high accuracy and repeat accuracy, which are key elements for robotic instruments in MIS. Further, the prototype is able to exert sufficient force and it is possible to perform a simulated needle insertion task using the manipulator, demonstrating the feasibility of the proposed mechanism.May 2019, Proceedings - IEEE International Conference on Robotics and Automation, 2019-May, 2663 - 2669International conference proceedings

- Construction of Automatic Scoring System to Support Objective Evaluation of Clinical Skills in Medical EducationIn this study, we focused on the automatic scoring of medical clinical abilities. The objective clinical ability tests that all undergraduate students take before starting clinical practice were considered. As these tests evaluate practical skills, there is a problem that the learning method is poor compared to the examination of other lectures. Therefore, in this study, we recorded the voice of a student examining a simulated patient using a microphone. We constructed a system comprising a speech recognition module and a scoring system that performed automatic scoring by checking against a prepared example answer. This system was evaluated by medical doctors.IEEE, 2019, 2019 41ST ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE AND BIOLOGY SOCIETY (EMBC), 4177 - 4181, English[Refereed]International conference proceedings

- Microsurgery, often performed for anastomosis of small vessels and nerves, requires micromanipulations of small tissues and thus requires highly specialized surgical skills. Robotic technology has great potential to assist with microsurgical treatments because of the high accuracy provided by robots; however, implementation remains challenging because the technical requirements of robotic surgery are far different from those in industry. One of the greatest challenges is that two surgical tools (e.g., tweezers) must be precisely and deftly moved around the surgical area in seven degrees of freedom (DOF) using one DOF to grasp each tool, and these tools are used in close proximity to each other. Additionally, high accuracy and rigidity at the tool tip are imperative for successful performance of the microsurgical procedure. In this study, we propose a new rotational two-DOF parallel mechanism that has the inherent advantages of a parallel mechanism, namely accuracy and rigidity, within a newly proposed spherical and non-spherical combined parallel structure to prevent collision of the two mechanisms in a dual-arm setup for microsurgery. The prototype was evaluated by performing a series of mechanical tests, and microsurgical suturing was performed by a microsurgical robotic system. The series of evaluations demonstrated the feasibility of the proposed mechanism.Dec. 2018, Journal of Robotics and Mechatronics, 30(6) (6), 846 - 854, English, International magazine[Refereed]Scientific journal

- Transpyloric tube insertion is a commonly intervention which consists in inserting a tube through the nose, the oesophagus and the stomach until the pylorus. This procedure can be done blindly if no licensed physician operator is available. Thus, the caregivers have to insert the tube without any visual feedbacks. The position of the tube has also to be conformed to avoid any issues. We proposed a guidance system for the insertion of this tube through an augmented reality application using an electromagnetic tracker. The trajectory and the orientation of the tube were visualized on a screen to monitor the tube insertion but also to conform the position of the tube tip inside the pylorus. This monitoring was improved by adding preoperative landmarks coming from a CT image or intraoperative landmarks obtained with ultrasound. Finally, the display was overlaid on a camera view to match the tube trajectory on the patient during the insertion so the clinicians directly visualized anatomical landmarks to guide themselves during the tube insertion. Preliminary results on one phantom showed the usefulness of our guidance system for blindly tube insertion. Further evaluations have to be realized on animals and on patients to validate these results.Springer Verlag, 2016, Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 9805, 198 - 207, EnglishInternational conference proceedings

[Purpose]Ultrasonography is one of widely used noninvasive and convenient methods. However, relatively large measurement variability is a problem to be solved. We developed a robot system for carotid arterial measurement by ultrasonography. In this study, we evaluated variability of the measurements of intima media thickness and carotid arterial diameter. [Methods] The robot consisted of one arm with 6-axis, which is operated by remote control with a probe shaped controller. Data acquisition was executed according to the sign which indicated the distinct intima separated from adventitia by echo-transparent media layer. The variability was measured by two observers with or without the robot system. [Results] There was no difference in acquisition time between the measurements with or without robot. However, variabilities of the measurements with the robot were lower than that without the robot (p<0.05). [Conclusion] The robot system has a potential to reduce variability of ultrasonographic measurements
- Development of intra-operative ultrasound navigation system for laparoscopic liver surgeryIn laparoscopic liver surgery, laparoscopic ultrasound (LUS) is indispensable to understand inner structure such as vessels and tumors. However, LUS is not convenient due to poor operability, and does not provide positional information in the endoscopic view. To address the issue, we have developed both a robotic hand for LUS and a 3D visualization software. In this study, we describe the software which provide 3D ultrasound by scanning LUS. To confirm the system feasibility, an experiment using a polyurethane liver phantom was conducted. Figure shows the reconstructed volume with vessels. The computational time was approximately 50 msec less than typical imaging period of ultrasound.2016, Transactions of Japanese Society for Medical and Biological Engineering, 54(PROC) (PROC), 1 - 2Scientific journal

- Operability study on the Multisensory Illusion inducible in Microsurgical Robotic SystemsThe Rubber Hand Illusion is a well known multisensory illusion in which the participant feels their own unseen hand become a rubber hand that is placed at the position where their hand is supposedly placed, triggered by synchronized haptic stimuli on their hand and the rubber hand. Our previous study showed that a robotized 1-degree-of-freedom rubber hand in the form of a master-slave system significantly enhanced the illusion compared with the classic rubber hand illusion. The illusion gives the sense that the part of body becomes part of the robot -it is thus assumed that this multisensory illusion is a potentially effective way to increase intuitiveness, and therefore increase the operability of a multi-degrees-of-freedom masterslave system. To further investigate the concept, we built a multisensory illusion inducible microsurgical robotic system based on the findings of the previous study and conducted a series of psychophysical experiments. The experimental results reveal that the multisensory illusion and operability is significantly correlated.IEEE, 2015, 2015 IEEE/RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS (IROS), 579 - 584, English[Refereed]International conference proceedings
- Robotic technology in the form of master-slave system provides dexterous motions in the confined workspace while increasing the accuracy in motion. Surgical robot is one example that the robotic technology has been successfully introduced in the market, and its applicable area is currently increasing. As an extension of the concept, we develop a laparoscopic manipulator to perform an ultrasonic scan in the abdominal cavity. The prototype was built as a hand-held device with three degree-of-freedom that can perform a dexterous ultrasonic scan in the confined abdominal cavity that has been difficult using conventional surgical tools. In this paper, we introduce the mechanical structure and its evaluation.The Japan Society of Mechanical Engineers, 2015, The Abstracts of the international conference on advanced mechatronics : toward evolutionary fusion of IT and mechatronics : ICAM, 2015, 126 - 127, English
- In recent years, robotic surgery has been widely performed in clinical practice, therefore the surgeons are becoming more and more familiarized with surgical robotic tools. Although the strong needs at clinical side, laparoscopy, one of the most performed minimally invasive surgery, is not widely performed using robotic system. To develop a further compact, lightweight, versatile surgical robotic system for laparoscopy, we designed novel robotic forceps developed based on Soft Robotics within the diameter of 6 mm. In this paper, we present concept, mechanical design and preliminary assessment of the developed prototype.The Japan Society of Mechanical Engineers, 2015, The Abstracts of the international conference on advanced mechatronics : toward evolutionary fusion of IT and mechatronics : ICAM, 2015, 62 - 63, English
- In recent years, robotic technology has been introduced in surgery in the form of master slave system and its applicable surgical area is widely spreading. Minimally invasive surgery and microsurgery are the representing applications of the robotic surgery that the surgeon performs the dexterous and ne operations in the deep or narrow surgical area in micro-scale. The intuitiveness is thus highly desirable to perform the highly elaborated surgical tasks such as suturing for surgical master slave systems. To increase the operability, time-delay of system response, haptic feedback and eye-hand coordination issues have mainly been discussed in the field of robotics. In addition to these approaches, we propose a surgical robotic system that induces multisensory illusion. In our previous study, we reported that the robotic instruments enhances the multisensory illusion. In this paper, we determine the requirements for inducing the multisensory illusion on a multi-DOF master slave system and the first stage of prototype implementation based on the given requirements is described.IEEE, 2014, 2014 JOINT 7TH INTERNATIONAL CONFERENCE ON SOFT COMPUTING AND INTELLIGENT SYSTEMS (SCIS) AND 15TH INTERNATIONAL SYMPOSIUM ON ADVANCED INTELLIGENT SYSTEMS (ISIS), 13(4) (4), 1238 - 1242, English[Refereed]International conference proceedings
- Physicians use ultrasound scans to do diagnosis by making real-time images of internal organs, because such scans are safe, inexpensive, and non-invasive. However, aging society and limited numbers of physician make it difficult for patients in remote areas to be diagnosed. Besides, physician's technical skills affect the interpretation of the scans and thus the results of the examination. Thus, development of a robotic system for remote diagnosis is required to solve the problems. For this purpose, we proposed the development of a robotic system for automatic ultrasound imaging focusing on human liver. In this paper, we present several elements developed for the robotic system. First element is an algorithm for estimating the position of liver to guide the probe to scan initial position which is the epigastric region. Second element is ultrasound probe scanning protocol design to obtain whole image of the liver. Third element is force control algorithm to maintain the contact between the probe and human body even though the patient is breathing. Fourth element is an algorithm for detecting and correcting the probe's position when improper ultrasound images occurred. These algorithms with an implementation program control the apparatus: a Mitsubishi Electric's MELFA RV-1 six axis manipulator and tested on human subjects. The results confirmed the effectiveness of the approach. © 2013 IEEE.IEEE Computer Society, 2013, 2013 IEEE International Conference on Robotics and Biomimetics, ROBIO 2013, 804 - 809, EnglishInternational conference proceedings
- One of the important tasks required for sonographers is an accurate positioning of ultrasound probe. Especially, the measurement of the diameter of the blood vessel is affected by the positioning error of the probe. For this purpose, we have been developing a robot system for the medical ultrasound diagnosis, which composed of a 6-DOFs probe manipulator and supporting arm. In this paper, we present an implementation of fully automated positioning algorithm of the ultrasound probe on the carotid artery, by means of image feedback. A probe holding robot firstly detects the patient skin, then scans and detects the longitudinal section of the carotid artery, guide the probe towards the position where the tissue layers of the artery walls are most clearly observed. Furthermore, a new method of the visual servoing for tracking the out-of-plane motion for the medical ultrasound is presented. Automated positioning algorithm is tested in eleven volunteers and the results show that the system successfully completed the task in 91% of the trials. Visual servoing algorithm is also tested and the experimental results show its effectiveness.The Robotics Society of Japan, Sep. 2011, JRSJ, 29(7) (7), 626 - 633, Japanese, Domestic magazine[Refereed]

In order to obtain a clear image of the carotid artery ready for medical diagnosis, the authors developed real-time image processing algorithms to detect the carotid artery and tissue layers of its walls in the B-mode ultrasound images. Sequential patterns of the ultrasound probe trajectory for scanning the surface of the neck and searching the carotid, were implemented and tested on the Waseda-Tokyo Women's Medical-Aloka Blood Flow Measurement Robot System No. 1 Refined II (WTA-1RII).

- Development of the Two-Wheeled Inverted Pendulum Type Mobile Robot WV-2R for Educational PurposesThe rapidly increase of personal robotic platforms and their applications in Japan represents a great challenge for universities to introduce undergraduate students the basic knowledge required to develop intelligent automated mechanisms. For this purpose; in this paper, we are presenting our approach to introduce first year undergraduate students of the Department of Modern Mechanical Engineering the basics of robotics systems. In order to foster the creativity of undergraduate students of engineering fields, we focused in developing an education tool designed to introduce at different educational levels the principle of developing mechatronic systems. In particular, the development of an inverted pendulum mobile robot Waseda Wheeled Vehicle No. 2 (WV-2R) has been proposed. Different kinds of experiments were proposed to confirm the possibility or implementing controllers as well as changing physical properties of the system to observe differences on the response of the system. From the experimental results, we could confirm the effectiveness of the proposed systems to control the angle of pendulum respect to the body base as well as by changing the radius of the wheel.IEEE, 2009, 2009 IEEE-RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS, 2347 - 2352, EnglishInternational conference proceedings
- Development of a Robotic Carotid Blood Measurement WTA-1RII: Mechanical Improvement of Gravity Compensation Mechanism and Optimal Link Position of the Parallel Manipulator based on GAIn recent years, due to the increasing rate of elderly people in Japan, the needs to detect adults' diseases at the early stage becomes a high priority. In particular, an increased interest in detecting heart and cerebrovascular diseases at an early stage may allow clinicians to begin treatment sooner (when more treatment options are available), when interventions are generally more effective and less expensive. For this purpose, the introduction of robotic-assisted technology has advantages in terms of repetitiveness and accuracy of the measurement procedure. Therefore, at Waseda University, we have proposed the development of a carotid blood flow measurement system to support doctors while using ultrasound diagnostic equipments to detect arteriosclerosis and myocardial ischemia by measuring wave intensity. In this paper, the Waseda-Tokyo Women's Medical-Aloka Blood Flow Measurement System No. 1 Refined II (WTA-1RII) is detailed. The WTA-1RII is composed by an ultrasound diagnostic system and a probe-supporting robotic device. The robotic device is composed by a parallel link manipulator (for fine adjustment) and a passive arm (for rough positioning). The WTA-1RII has improved the design of the gravity compensation mechanism (composed by a constant force spring attached to a slide guide). In addition, a genetic algorithm has been implemented to determine the optimal link's position of the 6-DOF parallel manipulator to increase the workspace. Finally, a set of experiments were carried out to determine the usability of the proposed system.IEEE, 2009, 2009 IEEE/ASME INTERNATIONAL CONFERENCE ON ADVANCED INTELLIGENT MECHATRONICS, VOLS 1-3, 717 - +, EnglishInternational conference proceedings

For this purpose; in this paper, we are presenting our approach to introduce first year undergraduate students of the Department of Modern Mechanical Engineering the basics of robotics systems. In particular, the details of the inverted pendulum system based on the robotic education kit RoboDesigner and the development of a two-wheeled inverted pendulum mobile robot are detailed. The first system is basically used by students of the Mechatronics Laboratory (2) where they receive lectures of the content of each proposed topic and then, a set of practical experiments are done.

- Development of Assisted-Robotic System Designed to Measure the Wave Intensity with an Ultrasonic Diagnostic DeviceIn recent years, due to the increasing rate of elderly people in Japan, the needs to detect adults' diseases at the early stage becomes a high priority. In particular, an increased interest in detecting heart and cerebrovascular diseases at an early stage may allow clinicians to begin treatment sooner, when interventions are generally more effective and less expensive. Recently, the Wave Intensity (WI) has been proposed as a new hemodynamic index that provides information about the dynamic behavior of the heart and the vascular system and their interaction. However; the repetitiveness and accuracy of the WI measurement depend on the precision of the positioning of the ultrasound probe. Therefore a positioning device for ultrasound probe is required. Such a device should not only be used to keep the position but also for the fine positioning of the probe. For this purpose, at Waseda University, we have proposed the development of a robot system to assist a carotid blood flow measurement using ultrasound diagnostic equipments. In this paper, the development of Waseda-Tokyo Women's Medical-Aloka Blood Flow Measurement System No. 1 Refined II (WTA-1RII is detailed. The system consists of an ultrasound diagnostic device, a 6-DOFs parallel link manipulator, a serial link passive arm, ball joint, and a joystick type controller. The WTA-1RII has improved the design of the gravity compensation mechanism. In addition, a genetic algorithm has by implemented to determine the optimal link's position of the 6-DOFs parallel manipulator to increase the workspace. Finally, a set of experiments were carried out to determine the usability of the proposed system.IEEE, 2009, 2009 IEEE-RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS, 510 - 515, EnglishInternational conference proceedings

Endoscopic submucosal dissection (ESD) is a radical operation for early-stage cancer of the stomach, colon, and esophagus. In ESD, circumferential cutting of the surrounding mucosa of the lesion and submucosa dissection are performed using electrosurgical knives by scope motion. However, this technique is the requirement of long-term training for safe and short time procedures. To address the issue, we have developed a robotic system using a commercialized endoscope for intuitive operation in one hand. The system consists of three parts: one is a holder for the control body of an endoscope, a grasper of the flexible shaft, and a master controller with four degrees of freedoms. The holder has two-rotation mechanism for two dials of the endoscope. In this study, mechanical tests were performed as measurement of scope motion by sine signal motion. From the results, the robot can manipulate each axis of an endoscope within 200 msec delay.

- 2A1-C01 Operability assessment on a multisensory illusion inducible microsurgical robotic systemBody ownership transfer in the rubber hand illusion is a well-known multisensory illusion in literature. In our previous study, we have investigated the components to increase the multisensory illusion using robotic instruments. Based on the findings shown in the previous study, we developed a microsurgical robotic system for the further investigation of multisensory illusion in the form of multi-degree-of-freedom master slave system. In this paper, we report the effect of multisensory illusion in terms of the operability on the developed microsurgical robot. The experimental results showed the operability is significantly correlated to the multisensory illusion.The Japan Society of Mechanical Engineers, 17 May 2015, ロボティクス・メカトロニクス講演会講演概要集, 2015, "2A1 - C01(1)"-"2A1-C01(3)", Japanese

- 3A1-D03 Toward Intuitively Manipulable Surgical Robot based on Multi-Sensory Illusion(Medical Robotics and Mechatronics (1))Body ownership transfer in rubber hand illusion is a well known multi-sensory illusion in the literature. In this study, we introduce the illusion into a microsurgical master slave system to realize a further operability. The developed system has been designed based on the preliminary study that we had conducted using 1 DOF motorized rubber hand with a wearable master device with a optical encoder on the index finger's MP joint. In this paper, we briefly introduce the concept and the mechanical setup of the system.The Japan Society of Mechanical Engineers, 24 May 2014, ロボティクス・メカトロニクス講演会講演概要集, 2014, "3A1 - D03(1)"-"3A1-D03(2)", Japanese

- 1A2-A20 Development of an Two-Wheeled Inverted Pendulum Type Mobile Robot for Educational Purposes : Hardware Design of the Waseda Wheeled Vehicle No.1In the recent years, in order to foster the creativity of undergraduate students of engineering fields, the acquisition of technical skills requires an interdisciplinary approach to understand the basic knowledge among different backgrounds. As an approach to cover different aspects of the Robot Technology, in this project, we focused in developing an education tool designed to introduce at both elementary level and higher level students the principle of developing mechatronic systems. In particular, the development of an inverted pendulum mobile robot has been proposed. In this paper, the development of the Waseda Wheeled-Vehicle No.1 (WV-1) is described. A set of experiments are proposed to verify the controllability and stability properties of the WV-1.The Japan Society of Mechanical Engineers, 25 May 2009, ロボティクス・メカトロニクス講演会講演概要集, 2009, "1A2 - A20(1)"-"1A2-A20(3)", Japanese

All programs were open to currently active surgeons throughout Japan, and the cumulative number of participants is over 2500. As results of analyses of the training programs, 1. The expert surgeon has more natural and stable hand motions. 2. Training brings the novice surgeon closer to the expert's performances. 3. There are some groups whose scores decrease after training, and their careers and individualities have certain characteristics. 4. It may be possible to set training programs suitable for each individual by clarifying these characteristics.

The tissue fusion technique without damages is hoped. Purpose) This study is aimed to clarify the mechanism of interdigitation by laser energy between collagen fiber, and develop the technique of tissue repairing and fusion without injuries. Results) The bundle of collagen fiber was loosened and was swollen at 45℃. The pressure proof was significantly strong in Group A and interdigitation of different collagen fiber was observed.

These devices have high resolution endoscope and are able to work regardless of high magnetic fields of magnetic resonance imaging devices. Animal experiments were performed and demonstrated the usefulness of our developed system. The improvements of sterilization policy or disposable parts policy will be necessary to adapt the developed system to clinical practices.

We have developed a new probe holding robot and algorithms for improving the tracking performance. By using sensor fusion of the patient respiratory volume and ultrasound image, we have successfully achieved a significant reduction of the tracking error compared with the traditional image feedback control.Competitive research funding
