This paper reports the development of an automated rice transplanter guided by a global positioning system and an inertia measurement unit using the controller area network bus. The actuator control command and data communication protocols comply with the ISO 11783. The project aims to develop an autonomous agricultural system for operation in the paddy field. The automated rice transplanter presented in this paper is the first stage in achieving the project objective. This paper focuses on the development of sensor and main computer connections to the operating autonomous unit and the use of common control protocols for each of the automated machines. A simple steering control algorithm was used for straight traveling. The automated rice transplanter made a turn at the headland of the paddy field and moved to the next desired path. After 12 straight operations, the rms lateral deviation was observed to be less than 0.04 m and the rms heading angle error was less than 3.6 deg. C 2009 Wiley Periodicals, Inc.

“…The VR technology can be used to analyze dynamic performance of the models, replace the traditional prototype test with digital manner, reduce development expense and cost of products, and improve product quality and performance [5]. The VR technology can reduce design cycle of the agricultural machines, improve comprehensive utilization rate of the agricultural resources, and provide a "true" platform for education, training and scientific research of agriculture technologies [6]. Based on the above description, this paper starts with physical motion law and dynamic attributes and establishes the virtual model of self-propelled agricultural machines in order to discuss application of the VR technology in the test of the selfpropelled agricultural machines.…”

purpose: discuss application of virtual reality in self-propelled agricultural machine test; Method: analyze current farm environment, establish 3D virtual scenario of a farm, construct a virtual reality system combining physical engine, mechanical kinematics and dynamics, and simulate whole performance of the self-propelled machine based on virtual reality; Result: the agricultural mechanical system based on virtual reality can accurately capture the realistic road conditions and accurately fit the navigation routes. The climbing and line brake test simulation results of the selfpropelled agricultural machine indicate that the whole traction, speed and vertical shift comply with the actual conditions and validate relation between the speed and shift. Conclusion: the agricultural machine design based on virtual reality is valuable for research on the agricultural modernization, which can reduce design cycle of the agricultural machine, lower design cost of agricultural machines, and improve mechanical performance, so it should be emphasized in industrial production.

“…Relative positioning systems are those that use relative references to the current or previous position of the tractor. For example, vision systems (Subramanian et al, 2006) that use the line of separation between the previous trajectory and the current one, or systems that use a laser reference (Leemans and Destain, 2007). On the other hand, absolute positioning systems use an external and global reference.…”

This paper evaluates the use of low-cost global positioning system (GPS) receivers in the autonomous guidance of agricultural tractors. An autonomous guidance system was installed in a 6400 John Deere agricultural tractor. A lowcost GPS receiver was used as positioning sensor. Three different control laws were implemented in order to evaluate the autonomous guidance of the tractor with the low-cost receiver. The guidance was experimentally tested with the tracking of straight trajectories and with the step response. The total guidance error was obtained from the receiver accuracy and from the guidance error. For the evaluation of the receiver's accuracy, positioning data from several lowcost receivers were recorded and analyzed. For the evaluation of the guidance error, tests were performed with each control law at three different speeds. The conclusions obtained were that relative accuracy of low-cost receivers decreases with the time; that for an interval lower than 15 min, the error usually remains below 1 m; that all the control laws have a similar behavior and it is conditioned by the control law adjustment; that automatic guidance with lowcost receivers is possible with speeds that went up to 9 km h -1 ; and finally, that the total error in the guidance is mainly determined by the receiver's accuracy.Additional key words: control law; fuzzy logic; inertial navigation system (INS); linear quadratic regulator; step response; trajectory tracking. Resumen Evaluación del uso de receptores GPS de bajo coste en el guiado autónomo de tractores agrícolasEste artículo evalúa el uso de receptores de posicionamiento global (GPS) de bajo coste en el guiado autónomo de tractores agrícolas. Para ello, se instaló un sistema de guiado autónomo en un tractor John Deere 6400. Como sensor de posicionamiento se utilizó un único receptor GPS de bajo coste. Se implementaron tres leyes de control diferentes para la evaluación del guiado con el receptor GPS de bajo coste. Se realizaron pruebas de seguimiento de trayectorias rectilíneas y de respuesta escalón. El error de guiado total se obtuvo de la precisión del receptor y del error relativo instantáneo en el seguimiento de una trayectoria. Para la evaluación de la precisión del receptor, se tomaron y analizaron datos de posición de varios receptores. Para la evaluación del error en el guiado, se realizaron pruebas con cada una de las leyes de control a tres velocidades diferentes. Como conclusiones se ha obtenido que la precisión relativa de los receptores GPS de bajo coste disminuye con el tiempo; que en un intervalo de tiempo inferior a 15 min, la precisión relativa es aproximadamente 1 m; que el comportamiento de las diferentes leyes de control es similar y está condicionado por el ajuste de las mismas; que el guiado es posible a velocidades de hasta 9 km h -1 y, finalmente, que el error total en el guiado está principalmente determinado por la precisión del receptor.
