Automation Reaches French Vineyards With A Vine-Pruning Robot


Now that Wall-Ye V.I.N. has been built we can rest assured that there are no jobs too sacred to be handed over to the automated expertise of robots. Wall-Ye is a robot that takes the human touch out of caring for those grape vines that make French wines among the best in the world.

Created by Christophe Millot, an inventor based in the Burgundy region of France, Wall-Ye will soon be taking on the most labor-intensive of chores performed in wine vinyards: pruning and de-suckering, or clipping off fruitless shoots. I asked Millot about Wall-Ye and how he might expect French winemakers to feel about putting the fate of their precious grapes in the hands of a robot.

Decked out in white with red trim, Wall-Ye stands about 50 cm (20 in) tall, 60 cm (2 ft) wide and weighs about 20 kg (44 lbs). As it travels up and down the rows of vines six cameras are used to navigate in between, image and cut the plants. Cameras located on the top and bottom ensure that it maintains a straight path in between the vine lanes. Other cameras store the shape and, with GPS, location of every vine. A 3D model AI tells it when to cut the shoots, which it performs with a pair of camera-guided arms with clippers. Unlike its human counterparts Wall-Ye never takes a break and can work day and night to prune up to 600 vines per day. That kind of productivity is why some winemakers are eager to get Wall-Ye working despite its 25,000 euro ($32,000) price tag.

Check out Wall-Ye at work in the following video.

But what about the purity of it all? Winemaking is an art non? Millot acknowledges that, even for French winemakers, economics trumps tradition. He says that there’s simply not enough seasonal workers to go around. The typical vine pruners, de-suckerers and pickers are young people on school break out to make some extra cash. But the problem is in August France goes on vacation, meanwhile the vineyards still need to be tended. Moreover, inexperienced pruners have to be trained for three years before they’re up to speed. It’s a lot of investment that, for some, yields too little return.

Inexhaustible as it is, however, Wall-Ye still can’t do all the things human workers can do. As of yet, the robot can’t actually pick the grapes. But Millot told me that grape picking capabilities will be added to the AI next year. “Everyone will benefit from the evolution of its brain.”

Wall-Ye was developed by inventors Christophe Millot, pictured here, and Guy Julien.

Not everyone is excited to replace their human hands. The owner of the Chateau du Val d’Or in Bordeaux, Phillipe Bardet, told the Daily Mail, “Technically it’s interesting, but intellectually, it’s inconceivable. It doesn’t fit with my philosophy of making a Saint Emilion grand cru.”

Bardet, then, won’t be too happy to learn that others are developing robots to work their vineyards. California-based Vision Robotics is developing a much larger vine pruner robot and Canterbury University in Australia is developing their own as well. All three robots use similiar systems: imaging that gets fed into AI 3D modeling to determine when and where to cut.

And in other parts of the world, other culinary specialties are feeling the encroaching robotic revolution. Sushi in Japan and noodles in China are now the domain of robotic chefs. Most headlines about automation focus on robot assembly lines in car factories or the gigantic Chinese Foxconn factory where robots have just now begun to land. But automation will increasingly move into smaller scale, local and less obvious enterprises.

In addition the jobs at stake threaten the joy of working in the vineyards. On a personal note, my wife and her sister are French and many summer hours of their formative years were spent pruning branches and picking grapes in the French countryside, accumulating a great many stories of collecting the goods by day and sampling the goods by night with their friends. It was backbreaking work, but it was also timeless fun. Concerned, I asked my sister-in-law how she felt about Wall-Ye. I was surprised when she told me that she thought it was great, that automation is a favorite topic on the agricultural stations in France, and she cheerfully acknowledged that they wouldn’t need her anymore.

Which leaves me with two conclusions, both of which I already knew: enthusiasm about technological progress is a cross-cultural phenomenon, and I still don’t get the French.
