Normally robotic arms are either cobot arms or industrial arms. A cobot is relatively safe to be around. They're meant to work with humans nearby so generally you'd have to be both inattentive and unlucky to get an injury that needs any sort of treatment. But these arms are relatively expensive, slow, and most can barely handle the weight of a typical box of vegtable. Industrial arms like this are more common. They're less expensive, faster, and can handle an unusually large box of veggies no problem. And mostly any arm large enough to move the box far enough to be useful in your workspace is going to be able to lift way more weight. But these are not safe to be around and either inattention or bad luck when you're around it will send you to the hospital. And both at once and you end up like the poor worker in the story. Needless to say be careful around cobots but don't be careful around industrial arms, instead use some sort of lock out system that makes it impossible for the arm to move if you're in close proximity because there's no way anyone will ever be careful enough. So, I don't blame them for using an industrial arm. But there was a serious failure that occured to ever let a person into the area while the arm was live.
