         | I am very confused as to why the robot was operating with such
         | power. According to the article, the robots pick up boxes of
         | peppers and place them on a conveyor belt. How does that
         | translate to such force so as to pick up an adult man, place
         | him on the conveyor belt, and then crush his face and chest?
         | 
         | There are clearly multiple safety protocols that were broken
         | here, starting with something as simple as a lockout/tagout
         | procedure and ending with robotic control system failures that
         | should have recognized it was needing to apply much more force
         | than expected to pick and place a box of peppers and also that
         | the thing it was handling was not a box.

           | 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.

       | Despite the headline, the robot arm itself probably has no smarts
       | and is just triggered to follow a routine when external sensors
       | on the line are activated. The issue is that the person may have
       | been unaware that the robot was energized, and there should have
       | been some safety interlock that de-energized the robot while the
       | person was in the robot's work envelope.

         | Assuming those assumptions are true, my question is whether the

         | 
         | If the worker needs to test/tune/adjust/repair the sensors, and
         | needed that system energized, was the robot built in such a way
         | that the sensor/control system could be energized, but the
         | actuator motors de-energized?
         | 
         | If not, the worker was stuck in a very dangerous position, and
         | was effectively killed by the robot's designers.

       | At a much lower power level, I had a couple harrowing experiences

       | 
       | One of the things I taught my kids when doing projects with power
       | tools at home is to unplug the cord after you are done
       | cutting/drilling/whatever and place the power plug right on the
       | machine where you can see it. With time you get used to not
       | approaching the machine unless you know where that plug is...in
       | the wall or on the machine.
