lab_pix1

So far, no one has ever used their eyes to see temperature distribution and thermal properties in the area of nano meter size (1/10000 of a single piece of hair thickness). In this project, special lights such as Evanescent light and Evanescent Fluorescent light are used to study new sensing technology to measure temperature/thermophysical property in extremely small areas. By using this new “Eye”, for example, Nano materials such as carbon nano-tubes and fullerenes and thermal system designs of IC chips that are integrated in high density. Subjects relating to application fields as mentioned earlier are expansively available.

Aim for an elderly-friendly system

As problems with the declining birth rate and aging population become more serious, the demand for wheelchairs will be expected to increase. This project uses an in-wheel motor (a drive shaft that has a motor directly connected to it) to build an independent two-wheel drive electric wheelchair. As well, I research on power-assisted control that is tough against fluctuating environment.

Research on biped walking robot with parallel mechanism

lab_pix4

A research on biped walking motions, basics of humanoid robot, is done. This unique biped walking robot with a parallel linkage mechanism makes possible for the legs to save weight by gathering motors in the waist area. As a result, walking with less energy and minimize shocks from contacting obstacles are possible so that the robot is friendly to humans and the environment. Also, location sensors that are located on the bottom of the feet allow to understand a shape of the ground, meaning that it is possible to walk on various environments such as a bad road.

The interface to support remote actions

In order to convey motions of a human hand to a remote location, I have developed a robot hand that resembles a human hand. Each finger can achieve rotation motion and linear motion so that, in addition to a motion to grab an object (grasping object), a motion to rotate an object (object manipulation) is made possible. Also, each finger uses technology to convey senses such as hard and soft so far away so that a user can feel an object in a far distance as if s/he is touching it in front of his/her eyes.

Applying robotics technologies on endoscopic surgeries

In order to assist in difficult surgeries like endoscopic surgery, an instrument called forceps was robotized. A doctor operates a master robot so that a slave robot actually performs a surgery on an affected area. This robot is applied as high technology called force sense to convey senses such as hard and soft very far way. Also, in order to control the robot, a special board being equipped with a device called FPGA has been developed. By using this technology, a difficulty level of endoscopic surgery will go down and the surgery is expected to be performed safely and in a short time.

Making nano/micro structures!

Aoyama and Kakinuma Labs.

As a next generation’s medical diagnostic technology, a diagnostic chip to check health condition using a small amount of blood is in the process of being developed. In order to manufacture the chip, it is necessary to process microchannels on the base with high accuracy, which requires processing technology of nano (1/1000000 mm) accuracy. Glass and special resin that are generally used for a base cannot be machine processed, but in this project, unique characteristics of the materials are being utilized to develop a technology for micromachining processing.

Development and application of special materials that responds to FIELDS

Materials that changes their characteristics when reacting to “fields” such as electric field and magnetic field are drawing attention because they have a potential to create new actuators and devices. In our research project, by applying electric field, development and application research on functional materials of which frictional property on their surface changes are in progress. Since it is possible to electrically control frictional property, these materials are expected to be applied for various purposes such as a force display device, a locking/brake device and a vibration controller.

Making the architectural space alive

Mita Labs.

lab_pix

Research is done, by having the architectural space to have immune function and DNA just like life, to create a pace that is safe, secure and comfortable. The immune function is useful for detecting unusual conditions that occur in a room such as intrusion by a thief, emergency of residents, breakages and deteriorations of a building. The DNA is useful for conveying necessary information that is required for constructing a building and evolving it on behalf of a blueprint. In order to make it possible, ways to utilize robots and sensor networks are suggested.

Digital Design

Aoyama Hideli Labs.

When designers design figures and colors, they sketch. Sketching is the most outstanding tool for designing in order for humans to express ideas and visualize them. This system allows to instantly (in real-time) create figures/colors in 3D from a sketch. It means that, without having to create an actual model, a user can check a design in the virtual world (the world within a computer), greatly increasing efficiency of designing.

Minimizing damages of elevators due to earthquakes

Kohiyama Labs.

http://www.kohiyama.sd.keio.ac.jp/

lab_pix

It has been a problem that long-period earthquake ground motions (slow earthquake tremor) cause damage to ropes for elevators in tall buildings. An analysis is done on a vibration model that has a building and an elevator together to do research on a method to increase the possibility of having an elevator available after an earthquake.

Designing and constructing experimental architecture on campus

Kishimoto Labs.

lab_pix

An actual architectural model has been designed and constructed within the campus.
The picture, “the forest rest area” on Yagami campus, has been created mainly by the graduate students.
This is a result of researching on architecture that comes from figures of lives/creatures through the graduate school project classes. (Kishimoto)

Stand for new threats!

Nishi Labs.

lab_pix

A side channel attack is a new threat that has been a problem in a way that it obtains confidential information by intercepting communication contents and processed contents through radio waves that leak from cables and connectors, power consumption from electrical devices and even sticking a needle directly to a cable.
To resolve this issue, Nishi Laboratory researches on anti-side channel attack technology. By utilizing the technology, threats that could not be resolved by security technology that conventional software offers can be prevented.
