This study aimed at design and control of machines and devices by means of artificial intelligence in tillage, seeding, thinning weeding and irrigation as well as tissue culture process.Minimum tillage was studied by carrying out a series of soil bin tests and field experiments on spring tines, which revealed specific features in comparison to ordinary rigid tines. Then, an expert system was constructed to select proper minimum tillage tools under given conditions and design a minimum tillage machine.To develop a precision seeder, three dimensional image analysis of soy- beans was conducted and their shape characteristics were formulated. Image analysis of field crops and weeds was done for a weeding robot and was able to distinguish weeds from crops with a probability of 68-95% under various conditions.Optimum control of irrigating plants was tried by means of self regression model and satisfactory results were obtained when the weight function of the optimum regulator was varied within the range of 1:10.A robot for tissue culture operation was developed to handle small protocorm under 1mm. A soft handling gripper was designed using a shape memory alloy and succeeded in transplanting protocorms in raw with 7mm spacing at with speed of 8 seconds for each protocorm.

本研究以人工智能为手段，对耕作、播种、疏草、灌溉和组培过程中的机械设备进行设计和控制，并通过一系列的土槽试验和田间试验，研究了与普通刚性齿相比具有特殊性的弹簧齿的少耕问题。在此基础上，建立了专家系统，用于在一定条件下选择合适的少耕工具和设计少耕机具，并对大豆进行了三维图像分析，建立了大豆的形状特征，为精密播种机的研制奠定了基础。除草机器人对田间作物和杂草进行了图像分析，在各种条件下，能以68-95%的概率区分杂草和作物。用自回归模型对灌溉植物进行了优化控制，当最优调节器的权函数在1：10范围内变化时，获得了满意的结果。利用形状记忆合金设计了一种柔性操作夹具，以8 s的速度完成了原球茎的原球茎移栽，原球茎间距为7 mm。
