Development of the Control System for an Agriculture Robot TAMBA2 with PLC - Development of the self - localization and radio control systems
No full textThis paper concerns the development of the measurement and control systems of the robot
"TAMBA2" for paddy fields. TAMBA2 is an agriculture robot which is developed by SHIMANO CO.
LTD. This robot has four legs with a crawler, a GPS receiver for self-localization, and a camera to recognize obstacles, and can work by radio control. In order to achieve the development target, the authors plan the measurement and control systems, and develop the radio control system.
Furthermore, validity of the use of the simplified differential positioning method by two GPS receivers for TAMBA2 is discussed
Acidic treatment method for hydrophilicity of hydrophobic carbon surface
No full textBiofuel cells convert chemical energy into electrical energy and provide several advantages over traditional batteries, including low-cost operation, environmental friendly energy, and potential for
miniaturization. These advantages have led to the application of biofuel cells in medical equipment and household batteries. Biofuel cells, however, a low current density compared with conventional fuel cells, and it is therefore important to development of electrode material with high specific surface
area.
In this study, the authors have focused on the carbon cloth that has high conductivity and high specific surface area. By using carbon cloth as an electrode material, it is expected that high output will be provided due to its high specific surface area to mass ratio. However, although carbon clothes
are extremely hydrophilic materials, many biological molecules are highly reactive in water, making it difficult to conjugate these materials effectively. Considering this background, the excellent property
of carbon cloth could be most exploited for their use as electrode by hydrophilic treatment. To date, there have been several pioneering studies reported on surface modification with various techniques.
Oxygen plasma irradiation is a common technique for hydrophilic surface, but the procedure requires expensive equipment that is costly to maintain.
In this study, we here propose and describe the method for hydrophilic treatment onto the
carbon cloth surface by acid treatment.
This approach could help to overcome the limitation described above, and be used in the
development of novel biodevices to surpass the performance of conventional devices
Campus words of “National Institute of Technology,Fukui College”
No full textThis study reports the findings of the campus words that intended for a fourth grader registered at National Institute of Technology ,Fukui College. I thought about words peculiar to Fukui College as the campus speech that was the subdivision of youth words and about the words peculiar to Fukui College that a student used (or he knows it), analyzed it from the viewpoint of “things” and “persons”. As a result, there was the negative evaluation word peculiar to youth words at both points
of view. The expressions were arranged by the thing which the person who saw and heard the words spilled a smile on unintentionally. A characteristic that gentleness and uniqueness of the Fukui College students were felt appeared
