基于直接施药方法的除草机器人

Development of Weeding Robot Based on Direct Herbicide Application Method

研究了控制农田杂草的直接施药方法,并研制了基于该方法的除草机器人。计算机从摄像头采集的地面图像中识别出杂草目标,然后通过伺服控制器来控制机械臂动作,末端执行器切割杂草并涂抹除草剂。田间和温室的化学除草试验表明,利用直接施药方法,极其微量的药物即可除掉杂草。该研究减少了除草剂用量并消除雾滴飘移现象,保护了生态环境。

An agricultural weeding robot was developed based on direct herbicide application method. Based on weeds identification data, an embedded computer sent instructions to a micro controller, which controlled the robotic arms to locate, cut weeds and applied chemicals simultaneously. The experimental results showed that only a small amount of regular spraying dosage was needed if chemicals were applied to do weeding directly without any drift.
