If you want to grow a field full of barley but don’t want to get your hands dirty, never fear: robots can do the whole dang thing.
That’s what researchers from Harper Adams University in the U.K. have shown. In a sleepy hectare of land in Shropshire, England, robots have been tending the land without a human setting foot on the field. A series of roboticized tractors and harvesters, along with drones for aerial surveillance, have carefully planted seeds, taken soil and crop samples, sprayed herbicides and fertilizers, and even harvested the resulting crop of barley. You can see them in action above.
