    In this study, we improve the efficiency of automated tomato harvesting by integrating deep learning into state-of-the-art image processing techniques, which improves the accuracy and efficiency of detection algorithms for robotic systems. We develop a hybrid model that combines convolutional neural networks’ dual two-dimensional matrices for classification and part affinity fields. We use data augmentation to improve the robustness of the model and reduce overfitting. Additionally, we apply transfer learning to solve the challenging problem of improving the accuracy of identifying a tomato’s center of gravity. When tested on 2260 diverse images, our model achieved a recognition accuracy of 96.4%, thus significantly outperforming existing algorithms. This high accuracy, which is specific to the environmental conditions and tomato varieties used, demonstrates the adaptability of the model to real-world agricultural conditions. Our results represent a significant advancement in the field of agricultural autotomization by demonstrating an algorithm that not only identifies ripe tomatoes for robotic harvesting with high accuracy, but also adapts to various agricultural conditions. This algorithm should reduce manual labor in agriculture and offer a more efficient and scalable approach for the future agricultural industry.

    Abstract

    Soybean as a valuable fodder and oilseed crop has taken the primary place in agriculture of the Amur region, occupying 75.4% of the total sown area in 2021. However, research and experimental data on the vegetable alternative of soybean for the region are insignificant. This study suggests that given complex economic, cultural, and climatic conditions changes, successful introduction and cultivation of vegetable soybean Edamame is timely and needs investigation. The climatic conditions analysis demonstrated that the mean annual temperatures increased in the observed period (1910-2021). Analysis of the similarities and differences in grain and vegetable soybean cultivation, including necessary agricultural machinery, suggested that partial re-equipment of the technical base for harvesting and postharvest processing of vegetable soybean could make it fully possible to cultivate Edamame. Given the high vulnerability of vegetable soybean to excess moisture and a tendency of the Amur region loamy soils to waterlogging, drainage amelioration measures were recommended. It is concluded that for the efficient cultivation of Edamame, further substantial research and longitudinal field studies of profitability, region-specific agrotechnology, and appropriate soybean varieties are necessary.

    To investigate the potential of fluorescence spectroscopy in evaluating soybean protein and oil content, excitation emission matrix (EEM) was measured on 34 samples of soybean flours using a front-face measurement, and the accuracy of the protein and oil content prediction was evaluated. The EEM showed four main peaks at excitation/emission (Ex/Em) wavelengths of 230/335, 285/335, 365/475, and 435/495 nm. Furthermore, second derivative synchronous fluorescence (SDSF) spectra were extracted from the EEMs, and partial least square regression and support vector machine models were developed on each of the EEMs and SDSF spectra. The R2 values reached 0.86 and 0.74 for protein and oil, respectively. From the loading spectra, fluorescence at Ex/Em of 230-285/335 nm and 350/500 nm mainly contribute to the protein and oil content prediction, respectively. Those results revealed the potential of fluorescence spectroscopy as a tool for a rapid prediction of soybean protein and oil content.

    International communication has sharply increased between educational and research institutions in the various sciences between Japan and Russia amidst globalization's rapid progress. Niigata University has been deliberately increasing collaboration with counterparts in the Russian Far East in the field of agriculture. However, literature comprehending current trends and issues of the bilateral joint research is insufficient. It implies strategical evaluation of the existing projects' efficiency and allocation of future collaboration tasks and funding. This study aimed to grasp the actual situation of Japan-Russia international joint research and its implications for agriculture. The authors used the Web of Science database aggregated by Clarivate Analytics to evaluate the general condition of research output and international joint research in both countries, fields of bilateral co-authorship, and Niigata university collaborative projects' results in terms of publication output in agricultural sciences. Results demonstrated steady efforts to promote international joint research in both countries. However, in terms of the research field, the bilateral relations are strongly manifested in materials science and physics, where the co-authorship rate is high. Agricultural sciences remain insignificant in bilateral cooperation. The number of co-authored publications has slightly increased due to the projects run by the Niigata university from 2015, both in Russian student enrolment and joint research specializing in agriculture. Therefore, the present study concluded that further profound qualitative and quantitative research on factors fostering bilateral collaboration, including international students' role, is needed.

    Research indicates that climate change aggravates extreme weather events resulting in flooding or soil waterlogging. Damaging abiotic stress imposed by flooding affects crop production negatively. Recently, floods, adversely affecting regional agriculture, occur in the Primorye region yearly. However, available statistics and research on flooding and its consequences for the region are fragmented and scarce. Based on meteorological data of temperature (1889 - 2019), along with annual (1911 - 2019), monthly, and daily (summer months 2015 - 2019) precipitation data in the Primorye region, this research aimed to grasp the exact situation in flooding events occurrence. The results demonstrated a significant increase in the mean annual temperature and extreme precipitation events. Further, the study discussed the deficiencies in the existing system of flood damage assessment and loss compensation. Deriving from the experience of the Federal Research Center of Agribiotechnology of the Far East named after A.K. Chaika (Ussuriisk), the study attempted to estimate the multifaceted negative economic and environmental impact of flooding events on crop production, including flooding influence on land fertility, the effect on pests and disease manifestation, impact on the crop seed quality. The results call for the further robust investigation of the structure (both tangible and intangible) and scale of flooding effects on regional agriculture and add-up to the knowledge base on the topic.

    After the collapse of the USSR, main agriculture complexes were destroyed and stopped their work since than soybean production in Russia had a challenging period and has only recently reached the peak level of the USSR production. Currently, soybean production in Russia has several main obstacles. It is essential to study the history and steps of the development of soybean cultivation. The rapid development of soybean production in the USSR was due to protein deficiency. Given the high content of protein and a considerable amount of valuable amino acids together with affordable low cost of production, the government decided to expand the cultivated area of the crop (Glycine max). Mostly, the soybean was used for livestock feed and oil production. The purpose of this paper is to study the dynamics of soybean production in the USSR and the primary agricultural practices that were used. This paper is focused on the Far East area, where since 1958 year, the cultivated area had spread significantly creating the leading industrial production zone of soybean in the USSR.

    This study aims to determine the dependence of the red band reflectance and near-infrared band reflectance in the evaluation of crops. The experiment using various fertilizers on soybean crops was analyzed to show the difference in reflections of red and near-infrared wavelengths. We used a multispectral camera attached to a UAV to obtain reflectance data of the surface. In this study, we used the normalized difference vegetation index, calculated based on red and near-infrared bands. The lower the value of red reflectance and the higher of near-infrared reflectance, the more chlorophyll, healthy vegetation, and the higher the crop condition. The decreasing photosynthesis rates and changes in leaf mesophyll are usually associated with decreasing reflectance of wavelengths within the near-infrared spectral range. We processed the obtained images and data from the camera and analyzed the reflectance separately for each plot of the surveyed field and each pixel of the image. The results showed in this paper that, according to a scatter plot analysis, different pixel concentrations were noted, which indicated by different information on the test field plot.

    <title>Abstract</title>The optimal design of a subsoiler implement is a complex work that includes optimal design, material properties, structural reliability, random variables, soil properties, soil tillage equipment, and optimum safety measures. The main objectives of this study were to design and simulate the deep placement fertilizer applicator (DPFA) by using the finite element method (FEM). FEM simulation software was used to select the optimum material properties and improve the safety factor by considering a range of loads on DPFA. Three applied forces in a static simulation (4500, 5000 and 6000 N) were considered as were three application depths of fertilizers (0.15, 0.20, and 0.25 m), to improve the safety measures of the design. The simulation results showed that the best material property for DPFA is the AISI 4135 QT carbon steel materials. This yields a high strength of 780MPa and an ultimate tensile strength of 950 MPa (Young’s Modulus of 207 GPa and with Poisson’s Ratio of 0.33). The static simulation for 6000 N shows that the DPFA model had a maximum stress and strain of 379.9 MPa and 25.6×10<sup>−4</sup> mm/mm respectively, with a contact pressure of 207 MPa, and a maximum displacement of 3.1 mm. The study results can provide theoretical and technical support for the development of agricultural tools, especially for DPFA in selecting optimum material properties and improving safety factors.

    This paper reports a field-scale study to detect differences in the amount of vegetation and chlorophyll content of crops using an unmanned aerial vehicle (UAV) fitted with a multispectral camera. The purpose of this study, on the experimental farm of Niigata University, Niigata, Japan, was to identify poorly-growing areas of vegetation that might require additional soil fertilizer. The normalized difference vegetation index (NDVI) and normalized difference red edge (NDRE) were obtained from five spectral band images (red, green, blue, infrared (NIR) and red edge (REDGE)) that were processed by software into a full image map. We used the image map obtained to analyze the farmland and identify variations in the greenness of plants. We compared two layers with different indices and indicated differences in vegetation activity for NDVI and NDRE. NDVI showed visible green color wherever vegetation was present. With NDRE we observed crops with low chlorophyll content, indicating nitrogen limitation in the leaves. These observations demonstrate the efficacy of using NDRE as a sensitive index for monitoring chlorophyll content. Therefore, we propose that different indices may be most useful for different crops, plant density, seeding rates and growth stages.

    This study evaluated elevation data in an agricultural field using an unmanned aerial vehicle (UAV) and a multispectral camera at an experimental site in the Amur Region, Russia. This region experiences waterlogging of soils, which prevents the use of agricultural machinery. Combine harvesters and transports are unable to perform technological processes on overmoistened soils. UAV surveying technology may help achieve a higher level of efficiency of agricultural land management. We processed captured Geo-TIF images using photogrammetry algorithms and recorded deviations in soil moisture on the experimental site. We produced a digital terrain model (DTM) that allowed us to determine areas of low-lying ground in the field that were prone to flooding and waterlogging. Using the UAV derived elevation model to determine low-lying ground may provide new opportunities for the region. Advanced land management may reduce farmers’ costs for maintaining machinery and labor in the field, especially during the harvest season.

    UAVs create accurate cartographic data for early crop and soil analysis, which is useful when planning land works and crop care activities. During the season, there is a need to organize field monitoring, for example, the geography of the land to provide further land management and field survey to indicate a crop health condition. Currently, there is an acute question about the introduction of new technologies in agriculture. Moreover, there are problems in obtaining new knowledge of agronomists and farmers that it becomes impossible to promote such technologies in poorly developed regions. In this study, we want to show the use of a drone and a multispectral camera in assessing the health of crops for identifying areas with depressed vegetation. These technologies are bringing a useful step in the development of an agricultural management system in the direction of increasing the efficiency of land use. We have started to introduce smart agriculture in Amur Region, Russia, where soybean production is the main direction in the development of the region. This project aims to expand the application of new technologies in Amur Region and in the Far Eastern part of Russia.

    The new implement “Deep-Placement Fertilizer Applicator” was developed. This implement has mainly two features. At first, it can conduct deep-placement fertilization which is one of environmentally friendly farming method. Second, this implement can save on labor costs because it simultaneously performs tillage, fertilization, seeding and suppression. In addition, an additional mature is not required because the effect of fertilizers is kept over a longer period by the deep-placement fertilization of the slow release fertilizer. In this study the modified model was developed with reverse rotational rotary to reduce power requirements. Experiments were conducted in Andosol soil to investigate the performance of the modified model quantitatively. The performance was compared with that of prototype model with conventional rotary under similar conditions. In this study, actual power requirements and soil pulverization performance were evaluated. The result clearly shows that the modified model was better than the prototype in terms of power requirements reduction and soil pulverization performance. The modified model consumed 16.7, 19.5 and 18.1% less power requirements than the pr

    In Japan, rice farming was influenced by the liberalization of the minimum access to rice trading. Because of this problem, the Japanese government promotes the improvement of the productivities of rice production. In the regions where large-scale farms aren't found, community-based group farming based on rural community is expected as a model of farming. In Japanese local areas. rural communities have been the basic units not only of social life but also of farming work. Group farming is an activity based on the rural community aiming to reconstruct rice production through co-operation of agricultural machinery, joint operation.

    In Thailand, the cost of sugarcane harvesting and transportation constitutes a significant portion of the total sugarcane production cost. In order to reduce the total cost, it is necessary to clarify the current shortcomings of the harvesting and transportation processes. A field study was conducted in Udon Thani province, in northeastern Thailand, to accumulate information for analyzing the system's current shortcomings. The accumulated information showed that mechanical harvesting is key for reducing harvesting cost by around 8 to 57 US$ per ha, when compared with manual harvesting in the case of burned and green cutting, respectively. In addition, analyses performed through the use of a simple sugarcane harvesting and transportation simulation based on data obtained by time studies of the harvesting and transportation operations indicated that the field capacity of a chopper-type mechanical sugarcane harvester depends on the condition of the field in which it works, and the number of accompanying trucks it requires. Though the sizes of the fields in this area are relatively small, the accumulated area of fields having row lengths of longer than 160m which allows the effective usage of a chopper was 316 ha or 51% of the total field area in this region. This fact shows that chopper can work at high capacity in half of the sugarcane fields in this region. However, the limited availability of trucks significantly influences the efficiency of mechanical sugarcane harvesting and transportation. In addition, since truck allocation affects the profit distribution among the various groups engaged in sugarcane production (i.e., sugarcane factories, machinery owners, and farmers) a truck allocation plan should be devised based on input from these groups.

    The allocation of mechanical harvesters and trucks to reduce the cost in sugarcane harvest influences the profit distribution among the three groups involved: sugarcane farmers, the owners of the trucks and mechanical harvesters, and sugar factories. These groups usually do not have common interests. Therefore, multi-objective optimization (MOO) was applied in this study to find a compromise solution. The parameters used in the MOO model were evaluated by using a simple sugarcane harvesting and transportation simulation derived from the field study in northeastern Thailand. The results showed that the compromise solution obtained from MOO was more acceptable than the solutions obtained from single-objective optimization. The results of analysis of variance indicated that the main factors influencing cost were the distance to a sugar factory, field size, and their interaction. In addition, cost reduction and efficient operation in mechanical harvesting and transportation were achieved in this study.

    The field performances of slot openers and residue handling devices have been studied experimentally in conjunction with the role of micro-managed surface residues which are advantageous for seeding and moisture conservation. Hairpinned residues and the area of soil disturbance were identified as the key factors in evaluating drill performance. The drill operations of four slot openers including a bubble coulter, a V-shaped, a VR<sub>A</sub>- and a VR<sub>B</sub>-slot openers were demonstrated. Regarding of hairpinned residues, a VR<sub>A</sub>- and a VR<sub>B</sub>-slot openers showed practically significant results to prevent from incorporation of hairpinned residues whereas a residue handling device acted to push the residues away from the slots. A bubble coulter and a V-shaped slot openers pressed the surface residues into the slots. A minimal area of soil disturbance occurred with a V-shaped and a VRB-slot openers. On the contrary, a bubble coulter disturbed a relatively wider area under bare soil (0t/ha) or lower level of residue density (2t/ha). A VR<sub>A</sub>-slot opener similarly disturbed a wider area under the given conditions. It can be concluded that a VR<sub>B</sub>-slot opener showed an acceptable practicability under the setting conditions. This unit could perform an ideal seedbed making actions in terms of the compressed slot, soil penetration resistance, hairpinned residues, and minimal area of soil disturbance so as to secure a higher percentage of seed germination and soil moisture conservation.

    Minimum tillage systems can possibly reduce soil erosion, conserve soil moisture, and also minimize labor and fuel consumption. To validate the effects of rice crop residues on drill performance, several field trials of four different slot openers were carried out to evaluate their drill performance on sandy loam soil with four different levels of residue density (0, 2, 4, 6t/ha) and three levels of soil moisture content (45%, 50%, 55% d.b.). The seeding of the drill operation was done with four models including a bubble coulter, a V-shaped slot opener, a VRA-slot opener and a VRB-slot opener. Field evaluations of these slot openers have been studied comparatively with regard to their slot formations, which are affected by the residue densities and the soil hardness in the influential zone that is near the bottom of each slot. Significant interactions between the residue density, the soil moisture content and the effects of residue densities have been discussed for each slot opener. In particular, soil penetration resistance tended to increase after the operations of a bubble coulter and a V-shaped slot opener under entire combinations of residue density. In terms of prediction, no significant effects of residue densities were found in the case of a VRA-slot opener and a VRB-slot opener. These two slot openers not only acted effectively to remove the residues prior to the seeding process but also confirmed the importance of a favorable slot profile preparation for stable plant growth.

    Compaction experiments on a Haplic Andosol sandy loam soil were conducted in a soil bin in order to observe the immediate effects of compost incorporation on compaction behavior characterized by penetration resistance, stress state and vertical strain. A selected type of compost processed from cattle manure and sawdust was added to the soil in proportions of 0, 79 and 132g/kg at soil water contents of 58 and 67%. Our results show that penetration resistance decreased with increasing amounts of compost at the lower water content, while the reverse occurred at the higher water content, probably due to changes in soil consistency. Similarly, the peak stresses significantly decreased as the amount of compost increased at the lower water content but this decrease was less pronounced at the higher level of soil moisture. Vertical strain was found to be greater in soil treated with compost than in control soil, indicating that soil-compost mixtures absorb stress transmission by allowing greater deformation.

    The experiment conducted in this paper combined dead reckoning and Laser Range Finder (LRF) applications in approaching a target with forward and backward movements of an autonomous tractor. In Part 1, an LRF positioning principle using reflectors for a tractor's backward movement toward an implement was discussed. This paper deals with the switching of sensors and navigation following a course composed of multiple segmented paths. Feasible segments were designed on either polar coordinates or Cartesian coordinates. While path design by Cartesian coordinates enabled such steering as parallel parking, polar coordinate-based design enabled movements attended with turns of greater than 90°. It was confirmed by experiments that an autonomous tractor could track a multiple-segment path. Experimental results during two-segment navigation (Cartesian to Cartesian) showed that the final lateral error was 2cm and directional error was 1° at the goal position. Two-segment navigation (Polar to Cartesian) for parking a tractor in a yard showed a final lateral error of 1cm and directional error of 1°.

    Approaching a farm implement to perform a hitching maneuver is an important task in agricultural automation. Such as, approach to an object requires a robust positioning method. This study aimed to develop a positioning method for an autonomous tractor to approach an implement in the field using an outdoor Laser Range Finder (LRF). Navigation performance based on localization of reflectors by the LRF was examined using an actual-size autonomous tractor. First, the accuracy of LRF positioning using flat reflectors was tested. The positioning errors of the flat reflectors were less than 5cm up to 15m distance from the LRF. Second, field experiments were carried out in which the autonomous tractor approached the implement on a concrete surface and a field covered with grasses. The results of the field experiments showed that the autonomous tractor could approach to the implement's position within a final lateral error of 1cm and directional error of 1°, for the single reflector positioning method, both on the concrete surface and on the field covered with grasses. In the two-reflector positioning method, approaching the implement was done within a lateral error of 1cm for the concrete surface and 2cm for the field covered with grasses; the directional error was less than 1° for both surfaces. These results confirmed that positioning with reflectors as artificial landmarks for an LRF enabled navigation of the vehicle to the implement's position with high accuracy.

    This paper introduces an outline of a workstation for the agricultural autonomous vehicles. It also describes a background estimation method based on the Kalman filter for detecting an agricultural autonomous vehicle. The detecting system has been achieved in eight steps: generation of a background image and initialization, adaptation of a background image, detection of a foreground image, computation for the connected components of a region; computation for the intersection of two regions; computation for regions with the aid of shape features; transformation of the shape of a region, update of a background image. In this research, performance of the background estimation method based on the Kalman filter has been compared with that of general background subtraction in terms of accuracy, using both images captured on a sunny and cloudy day. The results showed that increasing the accuracy requires more than 10 frames per second to detect an agricultural vehicle in the above conditions.

    This paper describes the development of a trajectory controller applicable to guidance systems for a trailer towed by an agricultural vehicle. The controller was basically a feed-forward type, in which a trajectory was given as a polynomial function in Cartesian coordinates. The objective was to navigate the trailer to a given destination by tracking the designed trajectory. Simulations using a kinematic model of the tractor-trailer system verified that the feed-forward controller could guide the trailer to given destinations in an errorless condition. However, when even a small calculation error existed, it resulted in significant offsets from the given destinations in the case of backing-up motion. Therefore, a feedback controller designed based on locally linearized system equations around a given trajectory was introduced in order to stabilize the system's backing-up motion, therefore reducing the final offsets. The performances of feedback designed based on pole-placement technique and based on optimal control method were compared. Although the simulation results showed that both feedbacks could stabilize the system, the optimal controller showed better trajectory tracking performance than did the pole-placement controller.

    A trajectory controller for a trailer proposed in Part I was tested by using an actual-size autonomous tractor and a trailer. A dead reckoning method was used for estimating the position of the tractor-trailer system. The experiment was conducted on a concrete surface. The experimental results showed that the feed-forward controller could not navigate the trailer to the given destination in backward movement, while the proposed feedback control could stabilize the system and guide it to that destination successfully. Performance of the feedbacks designed by the pole-placement technique and the optimal control method were compared. No significant difference in the final positional error was observed between the two feedback types tested. However, the maximum displacements in position that occurred during backward parallel travel from the origin to (8, 3)m in Cartesian coordinates were 14cm using the pole-placement controller and 9cm using the optimal controller. These results indicated that the feedback equipped with the optimal control showed the better trajectory tracking performance.

    This study attempted to develop a method to predict the degree of soil compactness in terms of bulk density, which varies as soil is subjected to vehicular loads. <i>In situ</i> experiments were carried out by measuring the stresses in soil underneath operating tractors using stress state transducers. The soil at the test site was sampled and investigated in terms of its pertinent properties. A neural network model was then developed to memorize the functional relationships that govern the changes in bulk density as a function of soil properties and stress parameters. The results demonstrated that the model could predict bulk density by a root mean squared error of 4.28% with a correlation coefficient of 0.838. Furthermore, the sensitivity analysis was performed to prioritize the significance of each input parameter presented to the network by adopting a method called the Relative Strength of Effect (RSE). The results indicated that both normal and shear stresses were the dominant factors influencing soil compaction. Besides, susceptibility to compaction was found to be dependent mainly on the initial bulk density and the moisture content of soil.

    In search for the innovative main frame structure, comprehensive research of the battery built-in frame (BBF) has already initiated in automobile industry. In this study, some preliminary experiments have been conducted under the concept of adjustable location of the frame itself while seeking maximization of tractive performance in accordance with corresponding drawbar pull power. The required rise time of torque for the DC motor was found to be shorter by approximately 1/20 than the one of a diesel engine. Three kinds of axle loads for front and rear housing were provided to identify specific interrelationship among the rear axle loads, wheel slip, and tractive efficiency. These results were compared with the one of theoretical approach for the confirmation of their validity.

    The electric tractor (ET) was fabricated and tested as an innovative approach in providing conventional agricultural machinery which puts emphasis on zero emission and potential acceptability for women and the aged. The objectives of this study were to propose the prototype and investigate its performance for the sake of further improvement. The ET was fabricated by converting a 20kW diesel tractor. The performance tests were focused on the energy consumption and drawbar pull characteristics of the ET. As the full-charge capacity of the battery used was 7.2kW·h, the energy consumption and driving range were found to be 0.60kW·h/km and 8.35km, respectively. This performance showed an insufficient level, when considering farming requirements, due to the limited amount of battery supply as well as power transmission losses. However, the ET offered better drawbar pull performance. Since its overall mass was 1065kg, it could attain 5.76kN with 14% slip and 3.89kN with 22% slip on asphalt and hard soil surfaces. The overall efficiency of the ET in transforming electrical power to the power available at the drawbar was 0.21-0.32 on asphalt and 0.17-0.24 on hard soil surfaces. In addition to this, the forthcoming design concept and further refinement were discussed.

    A trajectory control algorithm for front-wheel-steering vehicles was developed for the motion of such vehicles, which has a constraint known as "nonholonomic constraint". The trajectory control algorithm steers the vehicle from a starting point to a destination along the path described by a polynomial function without conflicting with this constraint. Though the polynomial function was determined directly from the initial and final conditions of the vehicle's trajectory design, iteration was required to design the trajectory of a mounted implement. The direct application of the algorithm could not stabilize the motion of the rear-mounted implement while the vehicle traveled forward, but it was confirmed through simulations that the algorithm was applicable by reversing the running direction. Thus by reversing the time, the trajectory of the implement mounted on the rear end of the vehicle could be controlled even in forward traveling.

    Trajectory control method of implements mounted on autonomous agricultural vehicles which are equipped with four-wheel-steering mechanism have been studied. This method was developed based on the fact that lateral moving speed and yaw angular velocity can be controlled individually in four-wheel-steering vehicles. The required condition for tracking was derived from simplified equations of motion with assumptions which include no tire skidding, steady state motion and a flat and level surface. A method for calculating steering angle which fulfills the tracking condition was also proposed. Simulations of 90 degree turns indicated that while the proposed control method make a mounted implement move on a given path preciously, the required steering angle was strongly dependent on the shape of the paths. After comparing three shapes of paths (square corner, circular arc and clothoid curve), it was concluded that the clothoid path is most suitable among the compared path functions.

    In this study, the static elastic-plastic analysis for the monocoque-type frame was carried out numerically. Several mechanical characteristics for three models in terms of structural strength were discussed considering those geometry deflection and stress distribution as evaluation criteria. Comparing with an A-model which was modeled on a marketable tractor, the alleviation of plastic strain, maximum geometry deformation and stress were attained by about 14%, 72% and 47% respectively in a B-model increased sidewall thickness. Stress fluctuations caused by parameter's manipulation were pointed out quantitatively through the modification of the thickness of sidewall at differential housing. In a C-model which was added partition wall, the alleviation of plastic strain, maximum geometry deformation and stress were also attained by about 33%, 88% and 54% respectively. It was found that the validity of the setting of the partition wall was confirmed. Accordingly, some quantitative tendencies in von Mises equivalent stress and equivalent plastic strain for specific two nodes in partition wall were clarified putting a prescribed load pattern per one cycle.

    本研究は,環境対応特性に関して比較優位性を示すルーラル電気ビークル(REV)を製作し,もってその環境保全効果に係る評価を行い,併せてこの新技術が生物生産圏に及ぼす波及効果を多面的角度から検討してREVの実用化に向けた考察を行うことを目的としている。得られた研究成果の概況は以下のようである。 1.試作した電気トラクタを改造して,PTO駆動機能を備えたREVを準備し,ロータリ駆動性能試験に供試した。Ni-MH蓄電池を搭載し,出力密度480W/kg,サイクル回数1400回の仕様をもつ蓄電池を用いた。システム総電圧は120Vとした。 2.ロータリ耕うん作業時,供試機と対象機であるディーゼルエンジン搭載トラクタの排気ガスでは,それぞれ,NO_xにおいて0.0017g/kmと0.70g/km, CO_2において140g/kmと430g/km程度の差が認められた。総合的に判断して,供試機の環境負荷低減効果は顕著であることが分かった。 3.1台の車両に積み込んで取り出せるエネルギー(つまり,有効利用可能エネルギー)は,供試機において約3331

    日本の農林業は,後継者の不足,労働力の高齢化・婦女子化の進行,コスト低減の必要性,安全で高品質な作物の生産,農業活動による環境へのマイナスの影響などの多くの問題を抱えている。このような背景下で,トラクタ等の農業用車両に自律走行機能を導入した「ロボットトラクタ」の開発が注目されている。従来の研究は,車両が圃場内を走行して作業するための研究を集中的に扱ってきた。しかし,高齢化する地域社会構造の中で人を助け,補助するヘルパーとして働く新世代のロボットトラクタには,ハンドリング機能と知能制御が必要となる。その基礎技術開発を目的として研究を行い,以下の成果を得た。 1.提案済みの直交座標における軌跡制御にフィードバック制御を導入し,軌跡追従性能が向上することを確認した。また,軌跡設計を極座標に拡張し,90度以上の旋回での軌跡制御も可能であることを示した。 2.この軌跡制御を応用することで,自律走行車両が肥料補給を自動で実施できる

    農業を取り巻く社会的経済的環境が年々厳しさを増すなかで,基幹動力源である農用トラクタに期待される性能特性にも変化が現れ始め,その研究開発に当たっては人間工学的観点からより良い機能性,快適性,安全性を付与するための総合的設計開発環境の確立が重要視されるに至っている。しかし,従来型フレームは,機関,動力伝達部,差動装置といった構成要素が支持フレームの役割を果たす一体構造を有するため以下の問題点が存在する。(1)構成要素の安全率を高く見積もり,破壊例の根絶を目指す設計思想で対処しているので質量増は避けられない。(2)構造上,フレーム自体への防振対策が困難なため運転者への振動伝達が著しく,健康の阻害及び作業性などの低下を招く。(3)質量過大のため,燃料消費率が増大するうえに世界の畑作地帯で顕在化している圃場の締固め問題を昂進する。本研究では,上述の社会的背景と当該フレームの問題点を考慮し,既存のトラクタ形態に固執しない設計自由

    日本の農林業が直面している諸問題解決のため、農林業用ロボット開発の基礎研究して自律走行システムの研究を行った。車両による作業を完全に自動化するためには、車両自身が作業用資材を補給することや、作業機を付け替えることが必要となる。そこで、本研究では、画像処理またはレーザーセンサによる作業対象、例えば資材補給場所の発見法と、対象地点への接近軌跡の制御法を開発した。具体的には、簡単な構造のレーザーセンサによる三角測量法を応用した作業対象の位置計測法を研究した。その結果、7m程度の近距離では10cm程度の精度で作業対象位置を計測できた。接近制御の研究は、非線形制御理論に基づいた手法を応用して、移動前に車両の軌跡を移動開始前に設計できることを目的として行った。まず、車両の後車軸中心の移動軌跡を表す方程式を線形化し、与えられた初期条件から接近走行軌跡が直接設計できることを示した。次ぎに、この方法を拡張して作業に
