or its like do it or its your ass. of course you should stand up for yourself but thats the definition of a really bad day when you gotta do that probobly easy to get into months of litigation by refusing work even if you are totally right if you get some expert sleezeball. could say you gave the company a bad reputation by causing a delay. but being a tough guy is kind of part of maintenance position IMO, they need to stand up to people alot to stay alive. and if you are around a bunch of brown noses then no one is gonna be getting your back and it suddenly feels like your the man from mars but that assumes someone is not being lazy or lying about safety to get more productivity. |

Machinery designed without suffiicient protection to be operated safely, especially if it's autonomous machinery (not directly controlled by human operators) is just bad engineering, whether those are called "robots", "hammers" or crapshit. Since protection always has its limits or can be uneconomical, at least give proper instructions and procedures so that no human can get closer to the machine than a certain distance. Just because it is called a robot and even more so if it is claimed to use "AI" doesn't give any excuse to that fact. Bad tools are just bad tools. --- End quote --- There are very extensive rules in the EU about moving machinery and "Cobots" that make manufacturing here more expensive, but I'm fairly sure it prevents these accident. When I was asking quotations about for example a CNC glue dispenser, they have to include an enclosure for it, so that the operators cannot put their pinkie where it doesn't belong. --- End quote --- Such lockouts do help a lot. But there is no such thing as fool proof. Without the full story we don't know if the poor guy who was crushed did lock out everything, and was done in because someone else thought he was done and removed or bypassed the lockout or some other fault happened. Some here will respond that a proper lockout can't be bypassed (operator has only key for lock for example), but Murphy has unlimited power. |

the robot had a grievance with its handler >:D |

This case makes me remember when I worked as a CNC maintenance guy (I have a non degree in Industrial Electronics and Electricity, who is a pain on the ass to get visas because is not a bachelor's but that's another question for another day - got visa denied in HK for a dream 9-6 job). The machines the company sold, Yamazaki Mazak, had safety interlocks, that we had to every single time we installed a new machine or made maintenance of an old one, put in working condition. As soon as I would leave the customers floor, such safeties would be defeated being by inserting a dummy key or rewiring it. For the customer was the difference in saving 2 to 5 seconds per part in a short 1 min operation. One of the customers had a "change of heart" when a worker in a CNC lathe with the securities defeated didn't close the door properly when starting the machine. The carbide bit broke at the middle of the operation, a sizeable chunk of it hit the rotating chunk by their jaws and come propelled directly to the gap on the door open. The user was in the NC control checking the data. Was a clean entry and exit on his head, through his brain, and he didn't felt anything. It was like a bullet wound. After that security increased 10 fold around the machines, tons of robots and automation was implemented, from part catchers to hoppers, conveyer belts, Kuka's and so on and preodically assessments was made by the company I worked for as "surprise visits" because some floor managers were again trying to defeat such to again save time even if the higher ups said no such thing would be done again... |

The person made a mistake of working near a powerful robotic arm when it was powered up. Now I suspect this was becuase they were problem solving in a hurry as it needed to be ready to show off to the press. The guards and interlocks were no doubt not in place yet as that would clutter up the photoshoot. But part of me thinks there could have been some software safeties in place. The unit has image recognition and it's been taught to know boxes and products so why not go the extra bit and teach it humans and to avoid them. This would add extra complexity but at least it could help avoid an ED-209 moment. |
