Pins are pretty heavy, and the machine needs to throw them around pretty quickly
- SteveNuts 3y agoI'm surprised they don't have failsafes that would stop it immediately if it suddenly has an extra 130+ pounds of load
- TylerE 3y agoThe common models in service haven’t really changed much since the 1970s.
- usrusr 3y agoI guess this is also the reason for the dangerously strong forces involved: lots of outputs (surfaces that move pins) powered from few big motors because there's hardly any control besides synchronisation through gears. If the market was big enough to support the adoption of robots arms to the pin setting use case there would be neither strings nor danger from old string-less machines.

- TylerE 3y agoIndustrial robots are far more dangerous as they can typically move fully in 3d, whereas an old mechanical system like these… yes it has a gazillion pinch points and minimal guards, but at least each movement will only do one thrust by (eg stroke back and forth or spin).
- viraptor 3y agoThey're 1.5kg and the machine slides them, not lifts. Even if it did need to put exactly that much force to lift them, 15kg is really unlikely to kill you - toddlers keep jumping on parents without murdering them.
- johnwalkr 3y agoI recommend watching a video[1] about how these things work. I really don't see how it's feasible to make this complex, heavy machine inherently safe to stick your arms in. And keep in mind these machines have been iterated on for 100 years or more by multiple companies. Modern ones are full of safety features, but they revolve around lockouts, not making everything so weak it can't hurt you.

- ikari_pl 3y agothank you. I've only ever seen the string ones, and was wondering what is the older system
- AndrewKemendo 3y agoI don’t understand this attitude Everything shown in the industry backs up the claim of its dangerousness to the point where this entire article revolves around an industry changing in order to make up for that. Why would you, somebody who is not in the industry and has absolutely no clue about this, have an opinion this strongly held?
- viraptor 3y agoThis was not an opinion about the machine or industry. I asked why the forces are necessary exactly because I don't know that part. I disagree with the response about the pin weight, because I've got enough clue about mechanics and safety to know it's very unlikely to be a full explanation. The lifting happens either on a conveyor or the lift/harness. We have existing systems that can ensure you don't crush people with the weight itself this way. The dangerousness may come from different parts like higher torque motors, or exposed parts, or programming issues, or ... So feel free to comment on that if you know the answer.
