Humans easily outperform machines when it comes to tightening and loosening screw fasteners. The future of manufacturing and recycling may depend on changing that.
In the pantheon of technologies that make our modern society possible, one of the most underappreciated and neglected is the threaded fastener, more commonly known as the screw. This technology emerged at the dawn of the industrial era, when it became possible to make metal gadgets like these on a large scale.
Today, these devices literally hold the world together. Our 21st-century lifestyles would not be possible without them, and they are likely to play an indispensable role for the foreseeable future.
Yet in a world where manufacturing techniques are increasingly automated, there is a problem. The process of screwing and unscrewing is still one in which humans outperform machines. Robotic devices have difficulty locating screws and their sockets and then manipulating screws and screwdrivers effectively.
[...] These researchers are part of a team building robots that can take apart electronic devices, like smartphones, for recycling. The project is called RecyBot, and its goal is to create a high-speed intelligent robotic system for dismantling electronics.
That's a considerable challenge, and one of the biggest headaches is unscrewing. So the team at least have this under their belt. But the same technology could be applied in a wide range of smart factories that have to assemble and disassemble components.

Or when another mechanic tries to take the wheel off and finds the nuts cross-threaded on the stud and has to replace the stud ($$), or worse when it causes your alloy rim to fracture.

I've seen a mechanic take a torch to a rim, because the thread and the stud were both stripped.
One mechanic is another mechanic's worst nightmare (or dream, if you factor in per-hour billing)

If I were a mechanic, I'd worry about the customer blaming *me* for the previous mechanic's shoddy work, and complaining about the high cost of repair because of all the extra time and parts needed. If a shop advertises a "$150 brake service" special, and then they find out they have to replace the lug studs or even a whole hub because of some shitty tire shop worker, do they get to charge much more, and what do they do if the customer complains? (Honestly, I don't really know because I do my own brake work and most other jobs.)
