New Zealand farmers have a new tool for herding sheep: drones that bark like dogs

You have probably read about robots replacing human labor as a new era of automation takes root in one industry after another. But a new report suggests humans are not the only ones who might lose their jobs. In New Zealand, farmers are using drones to herd and monitor livestock, assuming a job that highly intelligent dogs have held for more than a century. The robots have not replaced the dogs entirely, Radio New Zealand reports, but they have appropriated one of the animal's most potent tools: barking. The DJI Mavic Enterprise, a $3,500 drone favored by farmers, has a feature that lets the machine record sounds and play them over a loud speaker, giving the machine the ability to mimic its canine counterparts.
