A new solar-powered robot identifies and kills weeds and could limit the need for herbicides on farms.
The multibillion-dollar pesticide industry could be in for a shake-up. Currently, large amounts of herbicide are sprayed across fields, covering both unwanted weeds and crops. Crops have to be genetically modified to resist the weed-killing chemicals.
But a new technological development has created robots that roll across crops, identify weeds, and spray a small amount of herbicide to kill only the problematic weeds.
The four-wheeled robots identify and spray weeds with 95% accuracy.
Large companies such as John Deere have teamed up with robotics companies to design more robots like these to combat weeds in an economic and environmentally-friendly way.
These robots could be rolling off the shelves and onto the farm in 2019.
