This paper presents a new topological localization system for mobile robot navigation based on salient visual regions. These salient regions are obtained by computing the opponencies of color and texture among multi-scale image spaces. Then they are organized to construct the vertex of topological map using hidden Markov model. So localization problem can be transformed to the evaluation problem of HMM. In our system, the topological map of environment can be created online and the robot locates itself concurrently. Experiments show that higher ratio of vertex recognition, that is localization, is obtained. And our system can guarantee mobile robot navigation safely in unknown environments. © 2006 IEEE.

We propose in situ formation of gel microbeads made of a thermoreversible hydrogel for indirect laser micromanipulation of microorganisms, DNA and viruses. Irradiation,using a 1064 nm laser, of an aqueous solution mixed with pol-(N-isopropylacrylamide) through a high magnification lens resulted in the formation of a gel microbead at the laser focus due to heating The gel microbead was trapped by the laser and was used for indirect laser micromanipulation of microscale and nanoscale samples. Laser tweezers can typically handle a microscale object with size ranging from several tens of nm to several hundreds of pjm in a stable manner. However, a nanoscale object with a size of a few nm cannot be stably manipulated, and laser beam heating is a major problem. This paper shows a method of indirect manipulation of microorganisms, DNA and viruses using a gel microbead made from the poly-(N-isopropylacrylamide) aqueous solution. We succeeded in reducing the laser power for gel microbead formation, and in using the laser-trapped gel microbead for the manipulation of microorganisms, DNA and viruses.

Recently, automation in clinical test is raised as a fusion of bio and robotic technology. Particularly, automation in clinical test becomes a new application area of the robotic technology. In this paper, we present a robot platform for clinical test suitable for small or medium size of hospitals. The platform is designed to minimize the consumption of reagents, and easily integrate various testing equipments since it is functionally modularized. The platform is aimed for accommodating almost 70 kinds of clinical tests, which are the most frequently conducted in the hospitals. The platform consists of several major function blocks such as manipulation, transportation and detection, incubation, reservation, and each of them is designed as a module of the system. Basic ideas of the design are described and each functional block is explained in details. © 2006 ICASE.

To reveal the fire characteristics such as mass burning rate, flame height and puffing frequency of subsisting multiple fire sources, experiments were conducted for two small pool fires arranged in three dimensions. Two different kind of fuels, nheptane (luminous flame) and methanol (non-luminous flame) were employed for test fuels. Each pan diameter is 49 mm, and the two pans are arranged in horizontal distance between center of each pan ranged from 50 to 150 mm, in vertical distance between each surface ranged from 0 to 600 mm. As a result, mass burning rates for both of pans are lager than that of a single pool fire, especially the burning rate for upper pan is remarkable increases compared with that for lower pan. The external radiation heat and induced air flow by multiple flames contributes to increase of the burning rate for multiple pool fires. The flame height and the puffing frequency of multiple pool fires depend on the separation distance of each pan both in horizontal direction and vertical direction. The flame height for upper pan is smaller than that for lower pan, contrary the puffing frequency of upper flame is higher than that of lower flame.

It is well known that humans have high-level action intelligence. If such action intelligence could be represented in certain form, it can be applied to various fields such as the development of intelligent robot. Therefore we shall focus on imitation approach for the acquirement of human action intelligence. In this paper, from the perspective of emphasizing knowledge usage, we propose a novel imitation method of human action intelligence by using the Distance-Type Fuzzy Reasoning (DTFR) method with knowledge radius. Concretely, the employment of human action intelligence is achieved by DTFR method with knowledge radius;a learning algorithm for DTFR method, which is strongly combined with the DTFR method, is used for obtaining fuzzy rules representing human knowledge. Finally, based on a developed driving simulator, the effectiveness of proposed method is illuminated by experiment.

We have developed scanning laser range sensor called "SOKUIKI" sensor which is ultra-small scanning laser range sensor adopted for various types of mobile robots as we have already published. As a sensor for environment recognition, we thought the sensor must have not only outputting distance data but also another helpful function for mobile robots. So it was considered that what kind of advanced functions should be provided to SOKUIKI sensor. As a result two most important purposes were acquired. 1. Variation on its distance data and method to get the data. 2. The function for prevention of optical interference between sensors. These rolls were installed to the sensor, and confirmed their effect. This paper describes its result and proposes sensor communication interface protocol (SCIP) which is developed as new command system just for SOKUIKI sensor

In this paper, design principles and application of a thin and flexible intravascular top hat monopole probe with increased signal-to-noise ratio (SNR) and improved longitudinal and radial coverage are described and compared with the conventional monopole probe. The top hat probe is constructed by removing a segment of the shield of a coaxial cable. A flexible thin copper foil in contact with the inner conductor of the cable is added to the end section of the cable. The copper foil acts as an antenna top hat load increasing the uniformity of the current distribution on the probe and establishes a uniform region of SNR distribution around the probe. Improvement of the SNR distribution of the top hat probe relative to the conventional monopole probe is evaluated using quantitative indices. Experimental results show that for the top hat probe, the ratio of the maximum image SNR to its relative standard deviation (SR) is 2.73 times higher than that of a conventional probe. © 2006 IOP Publishing Ltd.

A motion support system is important for improving the quality of life for people with inadequate muscle power for walking or standing. Such a system must maintain coordination between the movement of the living body and that of the motion support system with respect to timing and power. We have developed a preliminary assistance device for human locomotion that does not restrict movement of the user's lower extremities. To determine the appropriate timing and applied force for this assistance device, we have use two types control mode; (1) surface EMG signals from the lower limb in preliminary controller. Each assistance leg has a three-axis magnetic sensor near lower end which tracks a magnet attached to each ankle of the user's legs. This sensor attracted to a magnet attached to the human ankle in the leg swing phase. The mechanical leg supports the user's weight when the leg is in the standing phase
