Companies are experimenting with high-tech tools that can help farmers save time and money, while reducing environment-harming chemicals. One of the companies
23、 is ecoRobotix of Switzerland. It created a robot equipped with AI and cameras to identify all plants on a farm. The robot has four wheels to carry it through the fields in search of weeds.

24、ls say the robot can fully operate on its own for up to 12 hours a day while being powered by the sun. It uses the same kind of sensor and positioning technology used to guide driverless vehicles. A farmer can also control the equipment through a smartphone. The co-founder of ecoRobotix, Aurelien De
25、maurex, says the farm robot can kill weeds with 20 times less herbicide than traditional methods.
