How an asparagus farmer's death spurred robotic innovation

It seems there are few jobs robots can't do these days, even the most delicate jobs, like picking asparagus or potting plant seedlings. But they're only needed because humans can't - or won't - do the work, farmers say. Marc Vermeer had a problem. He was struggling to attract workers to pick his white asparagus crop in the Netherlands. The workers he did hire moved on quickly, so he was always training new people.
