This paper describes an assurance diversity network platform for the New-generation Network (NWGN)/Future Internet. The primary focus is on the vision and five concrete network targets to realize the NWGN, which should ultimately contribute to global society over several decades. In the latter half of the paper, we propose a diversity network platform (DNP) concept for effectively accommodating various...
The authors have developed a system to autonomously classify the meanings of words using a knowledge database constructed from sentences found in textual content on Internet websites. This is a totally new system for classifying the meanings of words dynamically using only the connections between words. The authors believe that robots using such a system can approximate the knowledge of humans.
CAPTCHA is a technique that is used to prevent automatic programs from being able to acquire free e-mail or online service accounts. However, as many researchers have already reported, conventional CAPTCHA could be overcome by state-of-the-art malware since the capabilities of computers are approaching those of humans. Therefore, CAPTCHA should be based on even more advanced human-cognitive-processing...
This paper presents a hierarchical modeling strategy of the driving behavior based on the multiple levels of abstraction of the underlying dynamics. In order to realize this idea, a new mathematical model, Hierarchical PieceWise ARX model (Hi-PWARX model) is proposed. The identification scheme for the Hi-PWARX model is developed by synthesizing the ideas of a feature vector definition revealing the...
We have been developing a MKR (Muratec Keio Robot), an autonomous omni-directional mobile transfer robot system for hospital applications. This robot has a wagon truck to transfer luggage, important specimens and other materials. This study proposes a safe obstacle collision avoidance technique that includes a human detection algorithm for omni directional mobile robots that realizes a safe movement...
To realize the harmonious cooperation with the operator, the man-machine cooperative system must be designed so as to accommodate with the characteristics of the operator's skill. One of the important considerations in the skill analysis is to investigate the switching mechanism underlying the skill dynamics. On the other hand, the combination of the feedforward and feedback schemes has been proved...
This paper presents a new hierarchical segmentation of the observed driving behavioral data based on the multiple levels of abstraction of the underlying dynamics. By synthesizing the ideas of a feature vector definition revealing the dynamical characteristics and an unsupervised clustering technique, the hierarchical segmentation is achieved. The identified mode can be regarded as a kind of symbol...

A simple self-transfer aid robotic system is proposed, and the evaluations on the human's physical burdens when using a transfer aid robotic system are presented in this paper. A person with weak leg muscles who uses a wheel chair is assumed to be the target user. By using the self-transfer aid robotic system, a user can transfer between a wheel chair and a toilet, for example. The proposed self-transfer...
