Message from the Director
Center Director: Haruhisa Kitano, Professor, Department of Physical Sciences
The "Center for Advanced Technology (CAT)" was selected for the Ministry of Education, Culture, Sports, Science and Technology's (former Ministry of Education) 1996 "Private University High-Tech Research Center Development Project" and was attached to Aoyama Gakuin University College of Science and Engineering in 1998. This project was established in recognition of the importance of private universities in the development of science and technology, and with its substantial research facilities, it provides support in both hard and soft aspects to selected research projects, with the basic principles of "world-leading research" and "research open to the outside world."
Large-scale projects that have been implemented to date include the Private University High-Tech Research Center Development Project (1st phase: 1997-2001, 2nd phase: 2002-2006, 3rd phase: 2007-2011), which spanned three phases and 15 years, the 21st Century COE Program Research Center (2002-2006), the Private University Strategic Research Foundation Formation Support Project (two projects simultaneously adopted: 2013-2017), and the Private University Research Branding Project (2016-2020). In addition, we have implemented many externally funded projects with a maximum duration of three years per phase (a total of 13 projects selected since 2002). In 2021, 23 research projects selected by the CAT Research Project Selection Committee are being promoted.
As such, CAT's role as a research project base within the Faculty of College of Science and Engineering is extremely significant, and the research projects it has carried out have produced numerous world-class research results and have been highly praised.
Since the opening of Sagamihara Campus in 2003, CAT has consisted of eight experimental laboratories (two of which are clean room specifications) and a shared clean room in K Building. Together with College of Science and Engineering Instrumental Analysis Center, which was established when Sagamihara Campus opened, we believe that CAT will continue to play an even more important role in the future as a research and development center representing Sagamihara Campus.

Development of high-performance technology for microwave band radio wave absorbers (FY2026-2028) (Principal Investigator: Ryosuke Suga, Associate Professor, Department of Electrical Engineering and Electronics)
In recent years, with the advancement of the IoT society, devices that handle relatively high-frequency power, such as wireless power transmission, electric vehicles (EVs), and millimeter-wave radar supporting autonomous driving, have rapidly become widespread. While these devices make our lives more convenient and enriching, there are concerns about the risk of "electromagnetic interference," where unwanted electromagnetic waves are emitted into the surrounding environment, causing serious malfunctions in other electronic devices.
To prevent such deterioration of the radio wave environment and ensure safe communication and control, the importance of high-performance radio wave absorbers and shielding materials is increasing. Conventional materials have been hampered by thickness and weight, but in recent years, next-generation radio wave absorbers that are extremely thin and lightweight, made by regularly and periodically arranging metal or dielectric elements smaller than the wavelength, have attracted attention. In this project, we aim to further improve the performance of this new radio wave absorber by broadening its bandwidth and addressing oblique incidence, while also working on developing a highly efficient design method that quickly derives the optimal shape from complex structural parameters by making full use of electromagnetic field simulations and optimization algorithms.
Novel light source devices and wavefront control technologies for realizing an advanced photoelectric integrated society (FY2026-2028) (Principal Investigator: Tomohiro Maeda, Assistant Professor, Department of Electrical Engineering and Electronics; Co-investigator: Hideyuki Sotobayashi, Professor, Department Department of Electrical Engineering and Electronics)
In this project, we are engaged in research and development of new optical devices and optical wavefront control technologies to realize optoelectronic integration technology, which is expected to be the next generation of information and communication infrastructure. As the speed and integration of electronic circuits approach their physical limits, the importance of new information processing technologies that utilize the ultra-high speed and low loss properties of light is increasing.
This research is characterized by its integrative approach to different optical technologies: advanced light source devices using quantum dots and optical wavefront control technology combining optical metasurfaces and spatial light modulators (SLMs). In particular, by studying light source technology and optical control technology in an integrated manner, we aim to create new optical functions that transcend technological fields that have traditionally developed separately. Furthermore, by conducting research consistently from nanoscale structural design to the prototyping and evaluation of actual devices, we are promoting research that looks from basic research to applied development.
This is expected to have ripple effects across a wide range of fields, including next-generation optical communications, quantum information processing, and advanced sensing, and is also expected to contribute to the establishment of fundamental technologies that will support the advanced information society of the future.
Precise measurement of physical properties of small superconductors and their application to quantum metrology (2025-2027) (Representative: Professor Haruhisa Kitano Department of Physical Sciences Contributor: Assistant Professor Shintaro Suzuki Department of Physical Sciences)
In recent years, in the application field of metallic superconducting thin films, the development of quantum circuits using superconducting junctions and quantum sensors that utilize the ultrafast response and high energy resolution due to the nonlinearity of the superconducting transition and the very small superconducting gap has been actively pursued. Meanwhile, in the field of materials science, a variety of electron pairings that surpass the conventional concept of the mechanism of superconductivity shown in the BCS theory have been discovered in various material systems, and new concepts such as topological superconductivity and Majorana quasiparticles have been actively proposed and demonstrated. Furthermore, breaking the concept of solid-state physics that has long been discussed only in crystals and amorphous materials, the formation of long-range orders such as ferromagnetism and superconductivity has been discovered in the research field of quasicrystals that have a unique rotational symmetry that is not realized in crystals even though they do not have translational symmetry, and there is an urgent need to elucidate their mechanisms.
In this research project, we aim to apply the technology we have pioneered for precise measurement of the physical properties of microfabricated superconductor single crystals to candidate topological superconductors and quasicrystal-related materials, thereby extending the technology to non-contact physical property measurements that do not require fine wiring, and to demonstrate single-photon detection and elucidation of the physical mechanisms that will enable future applications in the field of quantum metrology.
Development of a credit scoring method that is robust against data bias (FY2025-FY2027) (Representative: Associate Professor Taku Yamanaka Department of Mathematical Sciences)
Credit scoring models are one of the corporate evaluation methods used by financial institutions and general companies when selecting business partners and monitoring business conditions. Building a credit scoring model boils down to estimating and learning a statistical model or machine learning model that takes a company's features as input and outputs a corporate evaluation value. Historical data on bankrupt and non-bankrupt companies is used to estimate and learn the model, but the large bias in sample sizes for both has caused difficulties in model estimation and learning. In addition, data bias in the sense that it is not possible to secure a sufficient sample size to build a model for some categories of corporate attributes has also caused difficulties in model estimation and learning. In this project, we aim to develop a method to deal with such data bias and realize a more robust credit scoring model construction method than before.
Development of thermal management technology using innovative heat transport devices (FY2025-FY2027) (Representative: Professor Koji Fumoto Department of Mechanical Engineering Contributor: Assistant Professor Ayami Hatamoto Department of Mechanical Engineering)
In response to global warming and environmental problems, technological innovation is required to achieve carbon neutrality, and thermal management technology is becoming increasingly important. Heat pipes have long been attracting attention as a capable heat transport device, and are used in many fields because of their simple structure, high performance, and no need for pumps. We have developed a new type of "serpentine low-filled heat pipe (MLFHP)" that exhibits extremely high heat transport performance. This has a similar shape to conventional self-excited oscillating heat pipes, but is capable of transporting heat with an extremely low filling rate of working fluid, achieving high heat transport performance despite its very small size and light weight. We also focused on loop heat pipes (LHPs), which are useful for large equipment, and are expected to achieve active and high-performance thermal control by combining these heat transport devices with fluid control technology. In particular, we aim to integrate thermal fluid control technology that does not have mechanical moving parts by using lightweight and highly efficient fluid control devices such as plasma actuators and EHD pumps.
Development of a material strength evaluation method based on local stress evaluation using X-ray diffraction (FY2025-FY2027) (Representative: Associate Professor Shota Hasunuma, Department of Mechanical Engineering Contributor: Assistant Professor Tomoyuki Hayase Department of Mechanical Engineering)
It is important to evaluate the local stress in evaluating the strength of materials. For example, since the destruction of equipment occurs from the stress concentration area, it is necessary to evaluate the local stress occurring in the stress concentration area. It is also important to understand the mechanical properties and residual stress of the surface modification layer such as shot peening, carburizing and quenching, and thermal spraying. However, it is not possible to measure the local stress such as the stress concentration area and the modification layer. Therefore, we focused on the X-ray diffraction method. The X-ray diffraction method is a method of irradiating the material with X-rays and measuring the lattice strain from the diffraction of the X-rays. The irradiation range of the X-ray is up to 2 mm, and the penetration depth is shallow at several μm. It is thought that by using this X-ray diffraction method, it is possible to measure the local stress of the stress concentration area and the stress-strain relationship of the surface modification layer. In this study, the purpose was to improve the accuracy of the material strength evaluation by local stress evaluation using the X-ray diffraction method. We aim to improve the accuracy of material strength evaluations through the development of simultaneous measurement of stress and strain distributions using a hybrid stress-strain measurement method using X-ray diffraction image correlation, evaluation of the stress-strain relationship of surface modification layers using X-ray diffraction, and development of an X-ray elastic constant evaluation method for thermal spray coatings.
Development of a wide-field X-ray monitor for the search for electromagnetic counterparts of gravitational wave sources III (2024-2026) (Representative: Professor Takanori Sakamoto Department of Physical Sciences Co-researcher: Assistant Professor Motoko Serino, Department of Physical Sciences Mathematics)
On August 17, 2017, an electromagnetic counterpart of gravitational waves from the merger of neutron stars was discovered, heralding the dawn of gravitational wave astronomy. From this electromagnetic counterpart, we observed kilonova radiation, which is radiation from unstable atomic nuclei produced by fast neutron capture reactions, which are essential for the synthesis of heavy elements, and gamma-ray bursts that are thought to be associated with the gravitational wave source. As the era of ground-based gravitational wave detectors LIGO, Virgo and KAGRA to detect gravitational waves from celestial bodies with the highest sensitivity approaches, we will study and develop a wide-field soft X-ray monitor using a Japanese-made flying observation instrument that can explore the electromagnetic counterpart. The accuracy of the direction of arrival of gravitational waves determined by gravitational wave detectors is several tens to hundreds of square degrees, so it is essential to have an observation device that can observe a large area of the sky at once with high sensitivity. In addition, the wavelength of X-rays has the advantage that it is easier to explore unidentified celestial bodies because the celestial bodies are not crowded with objects compared to visible light. To achieve this goal, we aim to realize a high-sensitivity, wide-field-of-view X-ray telescope using an optical system called "Lobster Eye" and an X-ray imaging element on a 6U CubeSat.
Project for the Development of Functional High-Temperature Superconducting Materials (2024-2026) (Principal Investigator: Junichi Shimoyama, Professor Department of Physical Sciences Co-investigator: Manabu Tokushige, Assistant Professor Department of Physical Sciences)
High-temperature superconducting materials are used in a variety of applications, including power transmission cables, electromagnets, bulk magnets, and SQUID elements, but they have not yet been widely adopted. This is due to the high cost of the materials, the fact that the material properties have only just reached a "usable level," and the immaturity of peripheral technologies such as superconducting joining technology. Therefore, this project is focusing on research to improve the performance of materials that are already in use or are close to being put to practical use. This not only aims to substantially reduce the cost of materials and expand the range of applications, but also to develop persistent current circuits by forming junctions, as it involves improving the homogeneity of materials and the surface condition of superconductors.
Specifically, this project is conducting joint research with companies on such topics as improving the performance of copper oxide high-temperature superconducting wire (Y-based) (Aoyama Gakuin Aogaku- Sumitomo Electric Industries), improving the performance of MgB2 superconductors (Aogaku Gakuin University - Tosoh), and developing highly versatile superconducting junctions between Y-based high-temperature superconducting wires (Aogaku- TEP [JST Mirai Project]). In addition, in a NEDO project, research and development of Y-based bulk materials and the design and development of Bi-based wires with new structures are also being carried out.
Research on peculiar electromagnetic field response in topological material systems (2024-2026) (Representative: Nobuo Furukawa, Professor, Department of Physics and Mathematics; Co-researcher: Tomoki Hirosawa, Assistant Department of Physical Sciences)
Electromagnetic waves have electric field and magnetic field components, which usually interact with the electric polarization (positive and negative charge distribution) and magnetic polarization (distribution of north and south poles) of solids, respectively. However, in some material systems, there exists magnetic (electrode) polarization that interacts with the electric field (magnetic field) component, which is called the cross-correlation effect or magnetoelectric effect. These are expected to be applied to new electronics elements such as strong radio wave absorption in the THz range due to electromagnons and microwave diodes due to non-reciprocal effects. Since a lattice or magnetic structure with a specific low symmetry is required to manifest the magnetoelectric effect in a magnetic material, research and development of an approach different from that of ordinary magnetic materials is necessary.
In this study, we focus on Skyrmion lattice systems and toroidal moment systems as peculiar magnetic structures in topological magnets, and aim to show that these magnetic structures exhibit magnetoelectric effects, that changes in the magnetic structure due to a static external field change the electromagnetic wave response, and in particular that the electromagnetic wave response of magnetic structures controlled by topological numbers (integers) is quantized (digitized), with the aim of obtaining various findings that will be useful for device applications.
Introduction of a microatom trap for detecting spontaneously formed molecular states of cooled Rb Rydberg atoms and for molecular generation (2024-2026) (Principal Investigator: Haruka Maeda, Professor, Department of Physics and Mathematics)
In this project, we focus on the spontaneous generation of molecular and cluster structures, which are an example of quantum many-body effects that appear in a cold Rydberg atomic gas system, in which low-temperature and high-density cooled atomic gas is excited to the Rydberg state. Specifically, we aim to experimentally detect molecular and cluster structures and ultimately understand the mechanism of spontaneous generation. At the same time, we plan to create a so-called microatom trap, a device that arranges individual cooled Rydberg atoms in an ultra-high vacuum and thereby precisely controls the molecular generation conditions. Furthermore, we aim to elucidate the nonlinear quantum optical process involving molecular states by preparing a pencil-shaped high-density cold atom sample in a 2D MOT (see image. Light emission from a long and thin cold Rb atom trapped in the center can be confirmed) to investigate the superfluorescence (superradiance) phenomenon, which is a typical example of quantum many-body effects that spontaneously appear in high-density atomic and molecular gases.
Interactions between nanopores and nanoslits and polymers, and the dynamics of cardiomyocytes (2024-2026) (Principal Investigator: Professor Toshiyuki Mitsui, Department of Physical Sciences)
Although single-molecule detection of DNA using semiconductor-based nanopores has some challenges as a sequencing technology, it is promising as a sensor for detecting viruses and observing DNA-protein interactions. However, there are still some unknowns regarding the interaction between DNA and the semiconductor material surface and the dynamics of DNA depending on the type of ionic solution. Therefore, we fabricate characteristic nanopores, track the movement of DNA visualized with a fluorescent probe, and evaluate the physical flow and electric field strength around the pore. In addition, we estimate physical quantities such as surface charge from numerical simulations using the finite element method and experimental results. In addition, we use chicken and zebrafish embryos and cells to study the response of mechanical stimuli to the beating of cardiomyocytes, the effects of chemicals, and cell dynamics on soft materials such as PDMS and gels that are close to the in vivo environment. This research aims to make a wide-ranging contribution, from basic developmental mechanisms to understanding heart diseases.
Creation of Functional Inorganic Thin Films as Environmental Infrastructure Technology (FY2024-2026) (Representative: Professor Yuzo Shigesato Department of Chemistry and Biological Science Co-researcher: Assistant Professor Minsok Kim, Department of Chemistry and Biological Science)
Many inorganic thin films, such as oxides, nitrides, hydrides, carbides, and alloys, exhibit unique and advanced physical properties, and further research and development is expected as functional materials that support the foundations of environmental and information technologies. These highly functional thin film materials are used in a wide range of fields in cutting-edge industries and are an important fundamental technology that supports modern society. This research project aims to establish high-order microstructural control to exhibit a wide range of high-level physical properties for functional inorganic thin film materials, which are essential for building next-generation environmental and information technologies, as well as ultra-high-speed deposition that can withstand practical use. We are conducting collaborative research with the National Institute of Advanced Industrial Science and Technology (AIST), the Technical University of Darmstadt in Germany, the Fraunhofer Institute for Advanced Science and Technology (FEP), and the Chiba University Center for Advanced Sciences, and collaborating with the Aichi Synchrotron Light Center.
Analysis of higher biological functions of animals (2024-2026) (Representative: Professor Hirata Fuzo Department of Chemistry and Biological Science; Co-researcher: Assistant Department of Chemistry and Biological Science)
Living organisms have higher-order functions such as perception, memory, learning, emotion, and judgment. The nervous system makes these functions possible. So how is the nervous system formed and how does it exert these functions? We are elucidating the higher-order functions of the nervous system using the tropical fish called zebrafish as a model. From behavioral experiments using zebrafish, we have revealed that a single chemical reaction changes protein dynamics in synapses (the connection between nerve cells), causing behavioral changes in animals and enabling them to adapt to their environment. We are currently starting a new research project to clarify the relationship between environmental factors that trigger behavioral changes, such as light color, sound, and temperature, and the higher-order functions of the nervous system, that is, brain activity, from various perspectives. In addition, we have used the genome editing technology CRISPR/Cas9 to create fish with various higher-order dysfunctions and to elucidate the mechanisms of pathological onset. We have created fish that develop epileptic seizures due to brain hyperexcitability, and by screening compounds that alleviate the symptoms, we are creating drugs to improve epilepsy. Through these brain science research projects, we will contribute to humans living healthy and fulfilling lives.
Development of highly efficient perovskite solar cells for indoor environments (FY2024-2026) (Representative: Professor Yasuaki Ishikawa Department of Electrical Engineering and Electronics Contributor: Assistant Professor Itaru Raifuku, Department Department of Electrical Engineering and Electronics)
IoT sensors that sense the state of various objects and connect to networks such as the Internet have been attracting attention, but power supply to IoT sensors is still mainly from batteries, and it is thought that environmental harvesting, which uses energy in the environment in which the sensor is installed, will play an important role in making the sensors lighter and maintenance-free. In this study, we aim to supply power to IoT sensors installed in indoor environments by developing perovskite solar cells that convert indoor light into electricity with high efficiency. Perovskite solar cells can be adjusted to materials that effectively absorb indoor light by changing the composition of the perovskite layer, which is the power generation layer. Compared to the illuminance of sunlight, the illuminance of indoor light is only about 1/200 to 1/1000, and even in such low-illuminance environments, perovskite solar cells are expected to have a photoelectric conversion efficiency of 30% or more. However, in order to make perovskite solar cells suitable for indoor environments, the instability of the electronic properties of the power generation layer is a challenge. In this study, we explore the optical properties of the perovskite layer with the aim of stabilizing the electronic properties of the power generation layer and achieving high conversion efficiency.
Development of new devices using nanocarbon materials (FY2024-2026) (Representative: Professor Huang Shinji Department of Electrical Engineering and Electronics; Contributor: Assistant Professor Watanabe Takeshi, Department Department of Electrical Engineering and Electronics)
Nanocarbon materials such as graphene and carbon nanotubes (CNTs) have attracted much attention due to their unique physical properties, such as excellent electrical conductivity, optical transparency, excellent mechanical properties, high thermal conductivity, and high biocompatibility, and their device applications have been actively researched. In this research, we are working on devices that utilize these properties. In order to maximize the excellent physical properties in device applications, we believe that the fundamental technology of crystal growth and synthesis technology of materials are important. Nanocarbon materials can be produced in various forms, such as uniform sheet-like graphene films with precisely controlled atomic layer numbers, and inks in which graphene flakes and CNTs are dispersed in a solvent. In this research, we are working to produce materials with optimal forms and physical properties for each device application and achieve high performance devices. Specifically, we are conducting basic research and device applications on graphene transparent conductive films, graphene electrochemical electrodes, and conductive cloth with CNTs attached.
Research on improving multi-phase wireless power transmission systems (2024-2026) (Principal Investigator: Hirokazu Matsumoto, Professor, Department Department of Electrical Engineering and Electronics)
Wireless power transmission technology is a technology that allows electronic devices to be charged without connecting cables. Because it allows for easy charging, it is becoming increasingly popular as a charger for mobile phones. Its major feature is that it can transmit power to moving objects. Current electric vehicles have a short driving range, long charging times, and expensive, heavy on-board batteries, which are obstacles to their widespread use. Wireless power transmission technology is thought to be one way to solve these problems.
The three-phase wireless power transmission system we have proposed is composed of a set of three phase coils, each of which has a different current flowing through it, and power is supplied by a three-phase inverter. In this system, the coils can be installed close together because the magnetic fields of adjacent coils are strengthened, and power can be transmitted seamlessly, making it suitable for transmitting power to moving objects. In this research project, we plan to improve the coils, circuits, and control system of this system to improve various characteristics such as increasing efficiency and reducing leakage flux.
Evaluation of heat transfer characteristics and crystal growth rate of sugar alcohol slurry (2024-2026) (Representative: Professor Hiroyuki Kumano Department of Mechanical Engineering Contributor: Assistant Professor Takashi Morimoto Department of Mechanical Engineering)
Sugar alcohol slurries, which are latent heat storage materials made by dispersing sugar alcohols in a liquid, have attracted attention as heat storage materials with high heat storage density due to the latent heat of solid-liquid phase change of sugar alcohols, as well as fluidity, and are expected to be used as heat storage and heat transport media in solar heat collection systems, etc. However, in the case of sugar alcohols, it has been suggested that the formation of crystals from aqueous solutions is extremely slow, and that the expected amount of crystals cannot be obtained in a certain period of time. Since the amount of sugar alcohol crystals corresponds to the amount of heat that can be stored in the system, it is essential to predict the amount of crystal precipitation. In addition, since the heat transfer rate is important during heat storage and heat dissipation operation, it is also necessary to clarify the heat transfer characteristics of sugar alcohol slurries. Therefore, in this study, we propose a model that can predict the precipitation rate of sugar alcohol crystals from a sugar alcohol aqueous solution, and by investigating the heat transfer characteristics when sugar alcohol slurry is flowed through a pipe, we aim to obtain basic knowledge for constructing a latent heat storage system using sugar alcohol slurries.
AE waveform classification and damage behavior estimation using machine learning (2024-2026) (Principal Investigator: Hideo Naga, Professor Department of Mechanical Engineering; Contributor: Miyuki Kadokura, Assistant Professor Department of Mechanical Engineering)
Carbon fiber reinforced composites (CFRP) are materials with excellent specific strength and specific stiffness, and are expected to be used in various situations in the future. On the other hand, since CFRP is composed of carbon fibers and matrix resin, there are many damage forms such as resin cracking, fiber/resin interface fracture, delamination, and fiber breakage. Among them, fiber breakage significantly impairs the soundness of CFRP, so it is important to evaluate the damage form before fiber breakage and grasp the signs of fiber breakage. Acoustic Emission (AE) used in this project is an elastic wave (ultrasonic wave) generated with damage and contains various information about the fracture. Therefore, if the characteristics of the AE waveform can be associated with various types of damage, the damage process of CFRP can be evaluated. Therefore, in this project, we classify the characteristics of the AE waveform by machine learning and associate various types of damage. In this project, we aim to develop a highly accurate classification method by quantifying and correcting the phenomenon in which the AE waveform is distorted as it propagates.

Development of Multiscale Stress and Strain Analysis Technology for Advanced Materials Using Hybrid Image Measurement and Numerical Analysis (FY2024-2026) (Principal Investigator: Satoshi Yoneyama, Professor Department of Mechanical Engineering; Co-investigator: Motohiro Moto, Assistant Professor, Department of Mechanical Engineering)
To reduce the weight of various machines and structures such as automobiles and aircraft, the use of multi-materials is progressing, and the use of carbon fiber reinforced plastics (CFRP) and high-tensile steel is increasing. To further reduce the weight of these materials, it is necessary to clarify the mechanisms of deformation and fracture of these materials and to enable highly accurate fracture prediction. In this project, we will establish a hybrid technology that combines image measurement technologies such as DIC and DVC with numerical analysis technologies such as FEM to develop a technology to measure the strain of high-tensile steel and CFRP at various scales, and to develop a technology to evaluate material properties and stress distribution using the measurement results. Specifically, we will conduct research on (1) establishing a DIC-FEM hybrid stress analysis technology and its extension to elastic-plastic and viscoelastic materials, (2) identifying the stress-strain relationship and evaluating the stress distribution after necking of high-tensile steel, (3) evaluating the deformation and fracture behavior of 3D printed energy absorption structures, and (4) developing a technology to measure strain inside CFRP using Global DVC/FE Global DVC.
High-speed 3D modeling, multimodal sensing, and robot motion control (2024-2026) (Principal Investigator: Ryosuke Tasaki, Associate Professor Department of Mechanical Engineering Co-investigator: Yuki Kimura, Assistant Professor Department of Mechanical Engineering)
This project aims to realize automation and robotics that can adapt flexibly and quickly to changes in the environment, materials, and tools in manufacturing sites and perform tasks sustainably. Therefore, a major goal is to realize skills similar to the advanced adaptability of humans in a robot system. Specifically, we are working to establish advanced production technology that handles liquids in the processes of "high-speed modeling with liquid-ejecting 3D printers" and "make-up finishing of industrial products, etc." In this research, we focus on building robot manipulation technology based on model prediction functions of computational fluid dynamics, high-speed visual measurement functions, and precise force control functions. We are building a method to execute state estimation and motion planning in a few milliseconds by making full use of real-time image analysis with a high-speed camera, and developing a high-speed drive module to realize it. Through this, we are pursuing and demonstrating the feasibility of diverse and complex liquid manipulation tasks through the design of a robot system with adaptability similar to human improvisation.
