I'm surprised they don't have failsafes that would stop it immediately if it suddenly has an extra 130+ pounds of load

  The common models in service haven’t really changed much since the 1970s.

    I 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.

      robot arms are quite strong and pretty dangerous when "on task" Chess robot breaks seven-year-old boy's finger during Moscow Open https://www.bbc.com/news/world-europe-62286017 https://www.bbc.com/news/world-europe-62286017

        Industrial 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).
