robots could do a lot of things better than humans... if the robots actually existed... and the problems/bugs/limitations were all worked out... and they had ready access to enough power to do the job... and they were affordable enough for anyone to bother... etc.

It's nice to dream about stuff we could maybe one day have I guess...

It’s a press release for a patent with a lot of “robot arm could …” and “once $THING_THAT_HASNT_HAPPENED happens…”, and the topper: “ Before the robot can be deployed on farms, the computer vision and positioning technologies that would let it find and reach for berries on the plant still need to be developed. ” Keep your long sleeved shirts and overalls handy, because robots are not going to pick your blackberries f…

Most of these ideas look great on paper, are easy to implement mechanically and then look great in the news, but then take years to become practical.

Every time I see these headlines, the tech seems to be at least 10 years away from product.

- demos done in a lab controlled environment without the crazy things that happen in a real world.

- no humans nearby so none of the safety features that would be needed should this thing work alongside/near humans.

- no regards for economics, expensive vision models, expensive hardware, no consideration for maintenance and repair costs

Having filled my share of blackberry flats, the first part of the picking motion is a ripeness check. You want the berry to be firm with a bit of give, and you want it to pull free from the plant easily. The force feedback sensors mentioned here seems to be for training purposes, but they would probably be better used on the finished grabbers to detect ripeness.

But can it harvest blackberries cheaper than humans?

And is it going to harvest the free blackberries I'm enjoying when I go on a walk? I don't think so.

I got schooled about the berries I pick on walks

There doesn't appear to be anything unique about this particular soft gripper. This blog post is incredibly speculative and really based on nothing more than the author imagining that a grad student's prototype could some day be a single part in a vastly more complex system. There are entire companies that have spent tens of millions of dollars and man-centuries of work trying to pick only strawberries, and strawberries are a lot more durable than blackberries. Vision, motion planning, and controls are all significantly more difficult than gripper design.

The authors didn't test if the robot hand can harvest better than human. They said it "could one day".

They have not even developed the piece that finds and positions the hand.

This is a classic example of University press releases, you learn to recognize the pattern. Someone who's skill set is PR gets a dumbed-down version of the science, and then converts that into a hype piece that ignores reality in favor of vague statements.

If you want the essence of this technique look at any university press release about fusion technology.
