I can see the possible benefit for small vineyards & farms, but at 4ha/hr it would take more than a week to cover a single paddock (field) of ours. Although I'd assume the controlling software would have good route planning, probably driven by drones doing weed spotting and NDVI/biomass analysis<p>I'd also like to know more about the kind of infrastructure you'd need to support autonomous operations, because if they're not autonomous they still a step behind current farm equipment.<p>Interesting how the WSJ and BBC articles contradict each other, one claiming plans are inexpensive while the other claiming they are. We use planes to complement our machinery, and they definitely aren't prohibitively expensive, and have far more use than just spraying chemical.
