I'm the author of this piece, and I'm happy to tell you where it came from.
I was at a robotics conference in Boulder last spring, where some folks from Lely presented a paper on their robotic code of conduct. I hadn't heard of robots for cows before, and thought it was fascinating. I happened to be in Rotterdam last fall for another conference, which was close enough to the Lely headquarters for a visit.
Lely is somewhat unique in that they're a robotics company rather than an agricultural machinery company that also makes some robots. There are a few other companies that make robotic systems like these, but Lely is the largest by a significant margin. Farms will often choose what brand of robot to buy based on what service center is closest to them, in case something goes wrong. I believe that Lely promises that they'll have someone on-site to fix (or, start fixing) a broken robot within about 2 hours.
The majority of farms who switch to these robots keep them- an expert that we talked to said that it's not common to go back, and only a small percentage do.
