Volkswagen Factory Worker Killed By a Robot
m.alessandrini writes: A worker at a Volkswagen factory in Germany has died, after a robot grabbed him and crushed him against a metal plate. This is perhaps the first severe accident of this kind in a western factory, and is sparking debate about who is responsible for the accident, the man who was servicing the robot beyond its protection cage, or the robot's hardware/software developers who didn't put enough safety checks. Will this distinction be more and more important in the future, when robots will be more widespread?
The regular safety measures weren't in place because they were installing the systems, so most likely they had people working on different things and someone started testing their piece without realizing it was already connected.
The more significant thing from a Slashdot point of view is that Financial Times writer Sarah O'Connor tweeted about it yesterday which coincided with the release of the new Terminator movie and it blew up into a somewhat inappropriate (someone did die) Twitter storm of SkyNet jokes.

In related news - one of the first reporters to tweet about the story works for the Financial Times has a rather unfortunate name relating to deadly machines. The reporters name being Sarah O'Connor.

First law of robotics: A robot without computer vision or radar may assume that it has free agency to operate within the convex hull encompassing its range of motion (otherwise referred to as its threatened area).
Even if the robot malfunctions due to other failures, those safety cages and perimeter markings are supposed to pretty much guarantee that you'll be safe if you're standing outside them, right? In that regard, one might worry more about robots that have autonomous control and unrestricted range of motion.
Where I work we have a large number of machines on assembly lines to pick-n-place electronic components and solder onto circuit boards, complete with PCB printers at the start of the line, and massive reflow ovens at the end.
Not only on the machines themselves being serviced, but also on the 480 volt 3-phase breaker switch boxes, and occasionally up further on the massive siemens transformers and converters (we pretty much have a mini power distribution station in-house) - all require multi person tag-out-lock-out.
At each point being worked on or powering what is being worked on, a scissor lock is placed on keeping power off and movable arms locked in place, which is then folded shut and provides room for up to six padlocks on it, any one of which prevents the removal of the scissor lock and each and every lock must be removed to take it back off.
Each worker puts their own lock on the scissor lock and similarly keeps the key on their person until a physical meetup after work is completed to remove the locks.
If even so much as one person isn't accounted for, their lock can't be removed, and power can not be reapplied.
There is no real way for power to be reapplied on accident, or because "the left hand didn't talk to the right hand" type of situation.
We once had a worker become light headed and dizzy on the job, and was taken to the hospital.
I was told it was a 48 hour process to legally remove his lock without his on-site presence, even with a witness physically with him at the hospital...

Right. I've worked on stuff that can crush a full size car without much load increase on the hydraulic pumps. And when I worked on that stuff, I had all the low voltage fuses in my pockets and my own padlock on the lock out lever of the power panel. The machines move too fast and with enough force that they would not notice a bit of flesh getting crushed until it was too late. On top of that, every machine I ever saw (CNC, relay and limit switch, or sonar actuated) had well marked exclusion zones that you just do not enter when the unit is energized... Unless the guy got inside the cage and then closed it up to over ride basic security(cage open=power off) I just can't understand this happening.

This. I've worked with industrial palletizing robots before and I've seen some amazing failures. A simple sensor not detecting that the pallet had jammed on the rack and the robot then proceeded to pick up the next box and place it at the bottom of the next pallet cutting the entire previous stacked pallet in half.
So imagine my surprise when I heard that someone at my work got fired when he defeated the safety locks to step inside the safety cage because every 6th movement the robot misaligned a box. We have security footage of him ducking under the robot's arm as it swung over it's head to fix the box every 6th movement.
There's a simple place to lay blame in most of these cases, and it's typically Darwinism or suicide.
