Polder and wiser

摘要

At the entrance to Hoeve Rosa farm, in the southern Dutch province of Limburg, a sign gives a warning that unmanned machines might zoom past. This farm is run by robots. They feed 180 cows, monitor their health, clean their stables and milk them whenever the cows choose. Fons Kersten, who runs the place, just needs to keep an eye on his phone. An app alerts him if a cow needs human attention.
