目前农产品最有利润的生产方式之一，是大面积栽种能够耐受农药的基改作物，并全面使用除草剂，以提高产出、增加收入。然而精准喷洒机器人来了，除草剂用量或可减少20倍，可能会颠覆当前的农业生产方式。倘若新技术普及，则只需对杂草喷药，人们对基改作物和农药需求将减少，这将更加环保！

You can see a machine in the field. It is the first completely autonomous machine for the weeding. It is made in Switzerland. Thanks to the precise detection and discriminating3 spraying4 of weeds， the herbicide will be reduced 20 times. Isnt it wonderful？

The weight of the autonomous robot weeder is 130kg. Highly efficient solar cells （380W） and battery power it energy. It has the anti-theft system. The communication is short （WiFi） or long-distance （mobile phone networks）. It works up to 12 hours a day without a human operator. The covering width is 2 meters. Per day it covers 3 hectares. The precision is less than 2cm. 95% of weeds can be detected and destroyed. The speed is 0.4 m/s averagely. The space between crops is 35 to 70 cm （adjustable）. Soil must not be too wet or viscous5. The maximum height of crop is 25 cm.

你可以看见地里有一台机器。它是第一个完全自动的除杂草机器，是瑞士制造的。因为它能精确地侦探并识别杂草来进行喷洒，除草剂用量将被减少20倍。这不是很棒吗？

自动机器人除草机的重量是130公斤，极有效率的太阳能电池（380W）和蓄电池给它提供能量。它有防盗系统，可短距离（WiFi）或长距离（移动电话网络）通信。在无人操作的情况下，它每天能工作到12个小时，覆盖广度是2米，每天它能处理3公顷的面积，精确度能达到2厘米以内，能发现并除掉95%的杂草，速度是平均每秒0.4米，所需庄稼之间的空间为35至70厘米（是可调节的）。泥土不能太潮或者太黏，庄稼的最大高度是25厘米。

How does the autonomous robot weeder work？ The solar energy， camera， GPS RTK and sensors enable it to follow crop rows， and to detect the presence and position of weeds in and between the rows. Two robotic arms then apply a micro-dose11 of herbicide12， systematically targeting the weeds that have been detected. Finally it can save an amount of herbicide. It makes the crops greener！How do you like it？

自動机器人除草机如何工作的？太阳能、摄像头、全球定位系统实时动态定位技术和传感器使它能跟顺着农作物的行，发现每行农作物中间和两行农作物之间杂草的存在和位置。然后，两个机器人手臂施用小剂量的除草剂，有条不紊地命中发现的杂草目标。最终，它能节约大量除草剂，让庄稼更绿色环保了！你觉得它怎么样？
