Development of Autonomous Mobile Robot with 3DLidar Self-Localization Function Using Layout Map

In recent years, there has been growing interest in autonomous mobile robots equipped with Simultaneous Localization and Mapping (SLAM) technology as a solution to labour shortages in production and distribution settings. SLAM allows these robots to create maps of their environment using devices such as Lidar, radar, and sonar sensors, enabling them to navigate and track routes without prior knowledge of the environment. However, the manual operation of these robots for map construction can be labour-intensive. To address this issue, this research aims to develop a 3D SLAM autonomous mobile robot system that eliminates the need for manual map construction by utilizing existing layout maps. The system includes a PC for self-position estimation, 3DLidar, a camera for verification, a touch panel display, and the mobile robot itself. The proposed SLAM method extracts stable wall point cloud information from 3DLidar, matches it with the wall surface information in the layout map, and uses a particle filter to estimate the robot’s position. The system also includes features such as route creation, tracking, and obstacle detection for autonomous movement. Experiments were conducted to compare the proposed system with conventional 3D SLAM methods. The results showed that the proposed system significantly reduced errors in self-positioning and enabled accurate autonomous movement on specified routes, even in the presence of slight differences in layout maps and obstacles. Ultimately, this research demonstrates the effectiveness of a system that can transport goods without the need for manual environment mapping, addressing labour shortages in such environments.

Innovative solution for increasing the performance of the cutting equipment for textile subassembly having variable geometry

Although the textile industry is in worldwide recession, the field of technical textile articles is in a continuous development, proving that the manufacturers of these products are concerned about finding solutions and creating high performance articles. Considering the need to increase productivity and product quality while reducing the consumption of materials, in the last decades, processing technologies specific to textile industry had a quick dynamic, that has led to the development of new, very efficient technological methods and processes, characterized by an advanced degree of automation. The proposed technological solution was developed based on the correlational analysis of the technological parameters of the variable geometry subassemblies, targeting the following technological aspects: monitoring of the functional parameters during the technological process development and real-time warning of the occurring dysfunctions; display of functional parameters and controls on a HMI touch panel display; adjusting the settings of the parameters of each inverter according to the dynamic parameters of the ordered devices (couple, speed, acceleration-deceleration, brake moment, etc.); PLC circuit logic programming via a software program dedicated to the application.

Anti-glare coating glass with sol-gel process

Background/Objectives: The next generation car such as self-driving car, and electrical vehicle is a hot issue of the automobile industry, which has the infotainment system with the multi-touch screen panel.Methods/Statistical analysis: The reflection of light from the surface of touch-panel display hinders the clean image acquisition of the display of infotainment system. In this research, anti-glare coating was fabricated by slot die method with the synthesized sols using the TEOS and functional binder on cleaned slide glass. The morphology and surface roughnesswere characterized by FE-SEM, and AFM. The optical properties of anti-glare coating were analyzed by UV-visible spectrophotometer and haze meter.Findings: The average transmittance of anti-glare coating glasses exhibits 88.5% - 90.5% in the visible light range of 400 nm to 800 nm wavelength. The haze value of the anti-glare coating has 7.1% - 36.6% to various coating conditions. The haze values of anti-glare coating were mainly affected by coated sol conditions rather than the coating conditions. The coating conditions of slot die method such as gap distance, and discharge rate of nozzle not affect the quality of anti-glare coating. The haze of anti-glare coating was affected by particle density, and particle size. The anti-glare coating of dense particle distribution and large particle exhibit large haze value about 37%.The best performance of anti-glare coatingwas 7.1% haze, 90.5% average transmittance, and 11 nm average surface roughness, which was coated with the solution #2 sol. The reflectance of anti-glare coating was not affected by change of haze values. But the transmittance of anti-glare coating was affected by haze.Improvements/Applications: The anti-glare coating glass can be applied to various applications such as protective glass of crystalline Si photovoltaic cells, window of skyscraper, and roof of airport buildings.

(Invited) Transparent Top Gate Oxide TFT with ITO/Ag/ITO Low Resistance Electrode for the Application to the High Speed Operation Fingerprint Sensor Array in the Touch Panel

Oxide thin film transistor (TFT) and low-resistance electrode are necessary to manufacture transparent and high resolution fingerprint sensor for application to touch panel display. We adopted ITO/Ag/ITO triple layered stack as an electrode according to that inserting thin Ag layer between both sides of ITO layers definitely helps resistance decreases. Through simulation and optimization, we have chosen each thickness of three layers for optimal transmittance and sheet resistance, and developed dry etching conditions. Top gate structured IGZO TFT with triple layered S/D electrode showed outstanding electrical performance and is expected to be applied to transparent display panel.

Mechanical Stability of Flexible Graphene-Based Displays.

The mechanical behavior of a prototype touch panel display, which consists of two layers of CVD graphene embedded into PET films, is investigated in tension and under contact-stress dynamic loading. In both cases, laser Raman spectroscopy was employed to assess the stress transfer efficiency of the embedded graphene layers. The tensile behavior was found to be governed by the “island-like” microstructure of the CVD graphene, and the stress transfer efficiency was dependent on the size of graphene “islands” but also on the yielding behavior of PET at relatively high strains. Finally, the fatigue tests, which simulate real operation conditions, showed that the maximum temperature gradient developed at the point of “finger” contact after 80 000 cycles does not exceed the glass transition temperature of the PET matrix. The effect of these results on future product development and the design of new graphene-based displays are discussed.

遠隔操作型メリクロンマニピュレータの開発

In this study, we developed an intuitive remote-controlled manipulator system that was operated using a touch panel display and a mouse. We examined its application possibility to pick out the shoot apical meristem from sprouting potatoes. The shoot apical meristem is not easily affected by plant viruses. Therefore, we can obtain a virus-free seedling that has a high production efficiency by culturing this part. This technique is called “mericlone” and is known widely in agriculture; however, it is tedious because of the precision work involved with a microscope. Thus, our system not only reduces the burden on the technician but also has high precision control and saves space. In this study, using the loop-mediated isothermal amplification method, we confirmed that we could get the potato meristems that do not contain Potato Virus X. The newly designed primer set can achieve results more rapidly, more easily, and with higher sensitivity than other virus detection methods, thus indicating the possibility of industrial implementation.

Development of First Production Flaw Detecting System for On-Demand Repair of Large-Scale Circuit

To realize an efficient high-mix low-volume production, improving the yield rate by reducing production flaws is an important technique. Manufacturing touch panel displays with large-scale wiring boards is a typical example of the high-mix low-volume production. The National Institute of Advanced Industrial Science and Technology (AIST) has proposed a laser assisted ink-jet printing (LIJ) technology, which can repair the flaws of circuits by a silver nanoparticle ink. To establish an in-process repairing system for a touch panel display, a first production flaw detecting system is necessary in combination with LIJ technology. Therefore, the aim of this study is to develop a new first production flaw detecting system, which detects flaws in a large-scale circuit quickly. In this report, we have covered the basic concept of the proposed system, and the details of some preliminary experiments conducted using the developed measurement system. The performance requirements for the first production flaw detecting system are discussed. The basic concept of the detecting system and optical set-up was finalized. A preliminary first production flaw detecting system with galvano-scanner and multi-photodiode array was developed to confirm its ability to detect flaws and pattern profile. Some basic experiments were conducted to check the performance of this system. A flaw was intentionally created by making a scratch on a circuit pattern; the experimental results showed that this flaw could be detected by the equipment. The height detection technique for this system and preliminary experiments conducted using the developed system are also covered in this report. By using the laser trigonometry method, the displacement of profile height was detected with sufficient accuracy.

Long-Term Safety of Repeated Blood-Brain Barrier Opening via Focused Ultrasound with Microbubbles in Non-Human Primates Performing a Cognitive Task.

Focused Ultrasound (FUS) coupled with intravenous administration of microbubbles (MB) is a non-invasive technique that has been shown to reliably open (increase the permeability of) the blood-brain barrier (BBB) in multiple in vivo models including non-human primates (NHP). This procedure has shown promise for clinical and basic science applications, yet the safety and potential neurological effects of long term application in NHP requires further investigation under parameters shown to be efficacious in that species (500kHz, 200–400 kPa, 4–5μm MB, 2 minute sonication). In this study, we repeatedly opened the BBB in the caudate and putamen regions of the basal ganglia of 4 NHP using FUS with systemically-administered MB over 4–20 months. We assessed the safety of the FUS with MB procedure using MRI to detect edema or hemorrhaging in the brain. Contrast enhanced T1-weighted MRI sequences showed a 98% success rate for openings in the targeted regions. T2-weighted and SWI sequences indicated a lack edema in the majority of the cases. We investigated potential neurological effects of the FUS with MB procedure through quantitative cognitive testing of’ visual, cognitive, motivational, and motor function using a random dot motion task with reward magnitude bias presented on a touchpanel display. Reaction times during the task significantly increased on the day of the FUS with MB procedure. This increase returned to baseline within 4–5 days after the procedure. Visual motion discrimination thresholds were unaffected. Our results indicate FUS with MB can be a safe method for repeated opening of the BBB at the basal ganglia in NHP for up to 20 months without any long-term negative physiological or neurological effects with the parameters used.

1407 タッチパネルおよびジャイロスコープを用いた多関節マニピュレータの無拘束遠隔操作システムの開発(OS11-1 ヒューマンインタフェース・ユーザビリティI,OS11 ヒューマンインタフェース・ユーザビリティ)

Independence support robots using multi joint manipulators are thriving in the field of welfare. Keyboards or joysticks are generally used in the remote operation of the multi joint manipulator. The posture of the multi joint manipulators can be ordered by the angle of the joystick or preconfigured key assignment. The control systems have a problem, however, that the number of operable joints is limited to the number of joystick axes or keyboard buttons. In this study, we propose a remote control system for the multi joint manipulator using touch panel and gyroscope. We call the system TGC (Touch Gyro Control). Miniaturization and performance increase are in progress to various sensors such as gyroscope and touch panel with the development of MEMS technology in recent years. In addition, these sensors have spread rapidly in our living environment. In this study, we use touch panel and gyroscope mounted on a smartphone. TGC system can control rotational movement of the maniplator using the orientation of the smartphone, translational movement in the horizontal plane using the drag operation of the touch panel display and translational movement in the vertical plane using up and down motion of the arm which is gripping the smartphone. For the quantitative evaluation, we experimented with 3D pointing using TGC and compared to the conventional method of button-type. The result of the experiment indicated that TGC could point faster than conventional button-type method. In addition, we also experimented with the task that grip and transfer screws into a box using 6-DOF manipulator which is controlled by above two methods. The result of this experiment also showed the advantage of TGC. The usefulness of TGC for the operation of the multi joint manipulator can be expected.

S115013 多機能携帯端末を用いた7自由度マニピュレータの無拘束遠隔操作システムの開発([S115-01]機械システムにおける機構の設計と要素技術(1))

In this study, we developed a non-restraint remote control system for a 7-DOF manipulator using a depth camera and a multipurpose handheld device (MHD) which is equipped with both a gyroscope sensor and a touch panel display. In this paper, we have evaluated the system as a 3D input device by 3D pointing trials. The results show there are not significant differences between our input method and commercially available 3D input device from a viewpoint of trial completion time. We implement our input method in a 7-DOF manipulator to confirm the intuitive operation of the non restraint remote control system.

2510 直感的操作可能な遠隔操作型メリクロンマニピュレータの開発

In this study, we developed the intuitive remote controlled manipulator system using touch panel display and mouse, and we examined the possibility of the application to the extraction work of the shoot apical meristem of the plant. The shoot apical meristem does not have the infection of the virus in the plant body. Therefore we can get a Virus-free seedling having high production efficiency by culturing this part. This technique is called "mericlone" and is known widely in the agriculture world, but this is hard labor because of precision work with microscope. This system we have developed not only reduce the burden on worker but also provide high precision controlling and space saving. In this study, with LAMP method (loop-mediated isothermal amplification method), we have confirmed that there was no PVX (Potato virus X) in the potato meristem with primordia using our developed manipulator system The newly designed primer set can discriminate the result.

Development of a Mobile Robot for Transport Application in Hospital

We have been developing the Muratec Keio Robot (MKR), an autonomous omnidirectional mobile robot system for transport applications in the hospital domain. This robot has a chamber to transfer luggage, specimens, and other materials safely. The robot has sensor devices such as a stereocamera, laser range finder and ultrasonic sensors to recognize surrounding environment and user interfaces such as a touch panel display and a display scrolling messages for interaction with human beings. Experiments are carried out at hospitals to verify the performance of elemental MKR-003 technology. Experimental results confirmed that the robot canmove without colliding with static or moving obstacles in a hospital. This paper presents the omnidirectional mobile transfer mechanisms, bumper switch, elevator passenger system and transport information systems.

Roll-to-roll fabrication of a low-reflectance transparent conducting oxide film with subwavelength structures

The transparent conducting oxide (TCO) film is a significant component in flat panel display, e-paper and touch panel. The tin-doped indium oxide (ITO) material is one of the most popular TCOs. However, ITO has high refractive index, so the phenomenon of high-reflectance limits the wide use of ITO. In this study, the structure and mass production process of new low-reflectance TCO film is verified. Laser interference lithography and the roll-to-roll UV embossing process are used to fabricate subwavelength structures on PET film; then ITO was deposited on structures by roll-to-roll sputtering. When the dimension of structures reaches 300 nm pitch, the optical reflectance and electrical performance of film are reduced to 8.1% at wavelength 550 nm and its transmittance rate is 84.3% at the same wavelength, and the sheet resistance of this film is 50.44 Ω/□. This result indicates that the new TCO proposed in this study is suitable for touch panel and other display applications.

Touch Panel‐type Dementia Assessment Scale: a new computer‐based rating scale for Alzheimer's disease

The Alzheimer's Disease Assessment Scale (ADAS) was designed as a rating scale for the severity of dysfunction in the cognitive and non-cognitive behaviours that are characteristic of persons with Alzheimer's disease. Its subscale, the ADAS-cog, is a cognitive testing instrument most widely used to measure the impact of the disease. However, the ADAS-cog takes more than 45 min to administer and requires a qualified clinical psychologist as the rater. A more comprehensive rating battery is therefore required. In the present study, we developed a computerized test battery named the Touch Panel-type Dementia Assessment Scale (TDAS), which was intended to substitute for the ADAS-Cog, and was specifically designed to rate cognitive dysfunction quickly and without the need of a specialist rater. The hardware for the TDAS comprises a 14-inch touch panel display and computer devices built into one case. The TDAS runs on Windows OS and was bundled with a custom program made with reference to the ADAS-cog. Participants in the present study were 34 patients with Alzheimer's disease. Each participant was administered the ADAS-cog and the TDAS. The test scores for each patient were compared to determine whether the severity of cognitive dysfunction of the patients could be rated equally as well by both tests. Pearson's correlation coefficient showed a significant correlation between the total scores (r= 0.69, P < 0.01) on the two scales for each patient. The Kendall coefficients of concordance obtained for the three corresponding pairs of tasks (word recognition, orientation, and naming object and fingers) showed the three TDAS tasks can rate symptoms of cognitive decline equally as well as the corresponding items on the ADAS-cog. The TDAS appears to be a sensitive and comprehensive assessment battery for rating the symptoms of Alzheimer's disease, and can be substituted for the ADAS-cog.

Elektrogustometr uniwersalny EG-1

Summary Electrogustometry has been used as a clinical tool for diagnosis and assessment of a variety of conditions. Since the lack of versatile electrogustometer for research and diagnosis, the new electrogustometer EG-1 was developed in 2006. It was done in cooperation between Warsaw University of Technology and Military Institute of Medicine in Warsaw. EG-1 allows quantitative estimation of taste perception threshold using both static and impulse electrogustometry with bipolar electrode. It is a fully autonomous, battery powered and portable instrument. Because of small size and weight, it can be easily placed in any environment. Microprocessor controlled measurement system and user-friendly interface (LCD display with simple keyboard) make EG-1 electrogustometer very handy and flexible in operation. Data obtained during measurements is stored in the internal device memory. After taste examinations measurement data can be transferd to a personal computer via inbuilt USB port for further analysis and storage. EG-1 can generate three predefined variously shaped current impulses: sinus-, saw- and rectangleshaped. There is an optional possibility of creating own shapes of stimulus puls by the user. The electrical parameters of generated pulses are as follow: current amplitude 1–2000 μ A regulated with 1 μ A step, stimulus frequency 0(DC)-500 Hz regulated with 5 Hz step, controlable fulfillment factor and signal rise time (optional for automatic measurements). The operator can trigger the stimuli via a hand switch on the bipolar electrode (with goldplated endings), via keyboard or via additional independent hand switch. Three years of experience collected during EG-1 exploitation allowed to design a new version of electrogustometer EG-2 with a touch panel and color graphical display.

Usability of Hierarchical Menu-driven Vehicle Touch Panel Display (Effect of Driving Task)

Investigations were made on the usability of hierarchical menu-driven vehicle touch panel display for multiple information system. The experiment to acquire one goal from sixty-four choices was performed for both with and without driving task using driving simulator. Tested menus are (breath^depth) 2^6, 4^3, 8^2 and 64^1. For the case of without driving task, usability of 8^2 is the best followed by 4^3. On the other hand, the goal acquisition time with driving task showed a decreasing difference between 8^2 and 4^3. Moreover, in considering subjective grading, 4^3 is the best closely followed by 8^2. Subjects feel 43 easier to use. This is mainly due to the ease of use in selecting the aimed sub-menu.
