This week's Tom Scott episode on Nebula* is interesting on this subject.

Long story short: folk from a university in Essex are working on creating a robot that can pick strawberries, but it (obviously) turns out that it's waaaay more complex than people think. There are untold different variables that humans just work around without having to think about them, like whether there are fruit inside the plant, obscured from view. A robot has to be programmed to be able to figure shit like that out.

Sure, it could easily run along the line just grabbing everything, but the plants in enormous growhouses can yield fruit for six months a year, so they need to be treated carefully. _ *it'll be on YouTube next week
