Behold the robo-berry – TechCrunch

If you've never picked a raspberry, well, first of all that's too bad, because a fresh raspberry is a beautiful thing. But second, and more immediately relevant in this case, you would not know that there is a technique to it that, surprisingly, robots aren't super good at because they tend to be… crushy. But this robo-berry designed by Swiss researchers could usher in a new era of gentle, automated robo-pickers. The secret to picking a raspberry is to grip it just enough to get purchase and then pull it downwards off the little stem, apparently called the "receptacle," which seems backwards. Seems simple -- and it is, but only our hands are among the most sensitive and finely controlled constructions in the universe, the culmination of a hundred million years of evolution, outdone only by (I suspect) raccoons.
