YAMAMOTO Chikafumi, MONTA Mitsuji, NAMBA Kazuhiko, GOTO Tanjuro

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) 2010 _1A1 - B05_1-_1A1-B05_3 2010

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

In the progress of precision farming, it is very important to collect variety of information on crops and field. In this study, we developed a prototype mobile eggplant grading robot in order to get information that be used for presentation of better way on cultivation. This robot can collect and accumulate the fruit's features information and location information at the same time while harvesting. After the field test experiment, a prototype mobile eggplant grading robot has achieved its purpose which was acquiring and storing information in real time and has created field spatial maps from the information. In the previous experiments, a rotary encoder was used in order to discriminate plant location based on the distance from the start point of the robot. However, the detecting error of the distance increased in proportion to the travelling distance of the robot because of the slip of the rotary encoder. In this paper, the robot discriminated plants by using IC tags attached to individual plants and a transmitter-receiver mounted on the robot. From the results, the robot could discriminate individual plants correctly.

Language：Japanese Publisher：The Japan Society of Mechanical Engineers

Many types of mechanized facilities have been constructed at many places in the world. Although automated systems have been introduced in the facilities to substitute human operators, there are many facilities where operators are forced to work under high noise and unsafe conditions from the mechanical systems. In this research, a speech and noise-sensing and reduction system was constructed and a virtual space was created with noise canceling headphones, microphones, a TV camera, and a host computer. The headphones reduced noise by providing inverse phase of the noise. Operators' speech signals including noise signals were collected by microphones at their mouths and were sent to the host computer from operators' small PCs through wireless LAN. The operators' positions on floor were measured by a TV camera installed on the ceiling of facility. The speech signals were sent back to individual operators' headphones after the speech levels were amplified based on the operators' positions, while the noise from the microphones was reduced by a method of spectral signal subtraction. An operator could hear the other operator's speeches in the virtual low-noise space according to their distances.

Language：English Publisher：The Japan Society of Mechanical Engineers

Precision Farming practices that required GIS and GPS system are too costly and impractical for small-scale farm. However, site-specific management is still necessary as it contribute in reducing the operation cost and also over usage of pesticides chemicals. A new approach in generating yield and quality map for small scale farm using mobile grading robot has been carried out. A prototype mobile eggplant grading robot was constructed and field test was done. The mobile robot consists of a battery railcar with the grading unit trailer hauled behind. Eggplant fruits were harvested manually and passed to the grading robot. Features information of the eggplant was taken simultaneously with the harvesting location information to create field variability map. Observations found that the constructed prototype robot was capable of accumulating the field variability information during the field test.

In this research, in order to clarify the fundamental flow characteristics of grain, the flow state in a vertical pipe was investigated. Brown rice, BB shot (pellets) "BB's" and soybean were fluidized by the air style. We determined minimum fluidization velocity and terminal velocity, recorded the flow state, and observed the flow state with a video camera. The results of the experiment were as follows:1) Minimum fluidization wind velocities were 1.6-2.1m/s in soybean, and 1.2-1.7m/s in BB's. This might be because of the shapes of soybean and BB's.2)A fountain state appeared in brown rice, but not in either soybean or BB's. This might be because of the shapes of soybean and BB's.3)Terminal velocity was 6.8m/s in brown rice, 9.5m/s in BB's, and 12.2m/s in soybean respectively.

Language：Japanese Publisher：JAPANESE SOCIETY OF AGRICULTURAL, BIOLOGICAL AND ENVIRONMENTAL ENGINEERS AND SCIENTISTS

In part 1 of this series, a sensing system consisting of a laser scanner and infrared sensors was manufactured and tested. The laser scanner was moved up and down by a lift to obtain a three-dimensional distance data, and the infrared sensors were used to detect the presence of human.<BR>In this paper, an algorithm for discriminating human bodies was investigated. From the results, discrimination was achieved even when human bodies overlapped each other crosswise with some distance between them.<BR>Furthermore, manipulator control experiments for obstacle avoidance were carried out to confirm effectiveness of the sensing system. First, the distances and the shapes of objects around a robot were measured by the laser scanner, and an avoidance motion of manipulator decided. Secondly, the manipulator moved while avoiding the object. The degree of danger was calculated when infrared sensors detected a human body around the robot, which then triggered adjustment of the speed of manipulator tip. From the experimental results, the manipulator avoided obstacles within its operating area and changed its speed according to the value of degree of danger.

Solar Energy Required and Predicted in Okayama and Giza(Egypt)

Elbatawi Ibrahim E. A., Mohri Kentaro, Elbatawi I.E.A.

Scientific reports of the Faculty of Agriculture, Okayama University ( 87 ) 187 - 193 1998.2

Language：English

Egypt as a developed country still has no electricity in many villages but at the same time has enough natural energy such as solar energy. Solar radiation data is not always available in many areas of the world and they have to be estimated using some sort of empirical model. The results of this prediction are compared for the measured data of two different countries: Japan (Okayama City) and Egypt (Giza City). The comparison shows an acceptable level of prediction between both of them. On a June day, actual accumulated insolation through one day was 18.88 MJ/m2 in Okayama and 22.79 MJ/m2 in Giza. On the other hand on a January day, actual accumulated insolation through one day was 4.93 MJ/m2 in Okayama and 5.49 MJ/m2 in Giza. We can see also that in January the worst solar month, solar water heaters still provide 35.25% of the energy for Okayama and 40.37% for Giza, That was because in Okayama the number of sunny days was only 6 but there were 19 in Giza.

Liu Houqing, Mohri Kentaro, Namba Kazuhiko

Scientific reports of the Faculty of Agriculture, Okayama University ( 87 ) 175 - 180 1998.2

Language：Japanese

Heat is transferred when the objected has temperature differences. In this research, the difference of two heating methods (far-infrared ray heating and hot wind heating) was analyzed. To compare their differences, the heat flux was measured by setting a heat flux meter beneath the surface of the object at different depths, then the heat conductivities and heat diffusion rates were analyzed. 1. Compared with hot wind, far-infrared ray heating has more heat flux before reaching a definite depth. 2. The heat conductivity and heat diffusion ratesby hot wind heating have specific properties with special objects. The heat conductivity and heat diffusion rate of far-infrared heating are higher than those of hot wind heating. The differences are considered to be caused by far-infrared rays.

Effect of Alternating Magnetic Field on Plant Growth

Nanba Kazuhiko

Scientific reports of the Faculty of Agriculture, Okayama University ( 85 ) 115 - 117 1996.2

Language：Japanese

This paper describes the effect of alternating magnetic fields on plant germination. Experiments were conducted utilizing various frequencies and two states of polarity.Electromagnetic coils were used to generate the fields and 'Komatsuna' plants were chosen as subjects. The frequency was varied from 1 to 1000 Hz,at a fixed intensity of 5 Gauss. The magnetic polarity was controlled by reversing the current direction. Measured parameter was the germination rate. The results indicated that magnetic fields do influence plant germination, and that frequency of the fields is a more important factor in germination rates than polarity. Maximum germination rates,which were 20% higher than control rates,were obtained at around 10 Hz.
