Each robot conducting cooperative operations, under control by wireless sensor network, at disaster site needs to maintain communication status. We will introduce and demonstrate a mobile robot network, that robustly maintains inter-robot communication based on the given control parameters acting as communication quality index.

Defects in graphite greatly affect macroscopic properties such as elastic constant, thermal expansion coefficient, electric resistivity, magnetoresistance, magnetic susceptibility, etc. To develop a graphite material with high functionality, we have studied structure of defects in graphite. As the feature of our exhibition, we will introduce the graphite that serves as a neutron moderator inside atomic reactor.

Measuring molecular dynamics in a cell in detail and over time is vital for creating mathematical models for biochemical reaction that regulates physiological activities. However, there is a practical limit to accurate experiments and continuous data collection by humans. We are aiming to build a fundamental technology for computer-aided automatic experiment and analysis systems using microfluidic technology.

There has been an effort to use scent as a medium. Scent information cannot properly be conveyed by simply emitting it because of scent fatigue and influence by remained scent. We have therefore developed a technology to emit scent at micro pulse duration and switch scents at extremely short intervals. Another development of ours is a tool, designed considering human's olfactory characteristics, to add scent to moving images and virtual reality spaces.

On the tabletop interface, there may be false identification of operators of digital objects and physical objects. We have developed a basic algorithm to reduce such false identification and allow more intuitive operation. Also, we have developed an application based on this algorithm.
