The screw feeder is pretty cool. There are a lot of these but this is the closest I could find to the model shown:
I wondered how the bit orientation and screw head were getting lined up. Is it the force and shape of the bit is enough for the screw to spin as needed and receive it?
Also, it seemed like the driver almost had force feedback over the screw points.
Because the worker’s arm seemed to slow just a bit out of what I’d expect. Could be just great precision though, if possible, why not try to keep the lateral motion confined or even on a particular track.
At that point it seems like robotics could be doing all this better.
Robots still aren't at the same amount of dexterity that humans can achieve, at least not in a price-competitive way.
Also, robots don't have the "automated QA" built-in that a human has - a robot will keep on placing screws and not notice something like a scratch or other imperfection, while a human can recognize this and yeet the partial assembly towards rework or recycling.
Some types of stainless are non-magnetic and thus can't be picked up with a magnetic screwdriver, thus the need to hand-feed the screw
Also, it could be in some stages if a single screw is not placed, it will lead to catastrophic failure of the product. (Hence the screw counter in that first stage shown)
