Autonomous farming robots that target weeds directly are poised to disrupt the current practice of mass spraying of herbicides.

Swiss company ecoRobotix is one of several newcomers in the emerging field of digital agriculture. Its solar-powered robot, which looks something like a pingpong table on wheels, can identify and spray weeds for 12 hours straight without an operator. Its developers believe it will use 20 times less herbicide than traditional methods that involve spraying entire fields.

All received their reward when a single bulb washed the village leader’s home with light. For the people of Chapasirca, life is brighter now.
