  • My Wife’s Father. I don’t care for him even if he has changed following a letter she wrote to him saying she’d be out of his life if he didn’t. In the past he beat her Mom and put my Wife through constant guilt trips. He honestly has changed a lot since the letter and he does very well with his grand daughter, but I just wanted to be home with my wife and daughter after working 70 hours out of state on a retrofit job. My Wife’s mother and step father will be visiting new years weekend. I just want it to be my family, but my Wife needs the help watching our daughter while I’m gone for work, so I just put up with it like any decent human would.






  • I’m not wrong. I’m stating my opinion. If I am wrong in stating my opinion than you are wrong as well for stating your opinion. I have a pair of open headphones, Audio Technica R70X. They still allow music to escape just as bad as it would be for a Bluetooth speaker to be playing at low volume. Perhaps Samsung Buds Pro 2 could work, but why would you want to seal yourself away from nature that much if you’re out hiking? Bluetooth speaker has been an appropriate choice in my experience.





  • When I shop on Amazon and see the obvious China companies that sell the same product but have the strangest names. Definitely avoid those products. If I see a.company only ships via fedex, I avoid doing business with that company. Dang, I know I have more just can’t think of them right now with morning brain.

    Edit: I avoid many major brands too. I belive them to be selling because of the name alone rather than having a quality product anymore. Dr Scholls is one of those,





  • Even if it was a vision system, which I highly doubt it was, there is no way a vision system could mistake anything for anything other than what it was programmed to see. Vision systems are finicky little bitches to setup. Gotta make sure your lighting is consistent and perfect, can’t place the machine near windows or else the sun will fuck up your vision system, etc. The late worker had to have accidentally triggered a box presence sensor while having the robot unsafely bypassed into a not-safe running state.

    I once had to male 36 vision programs into one robot. That’s 1 vision program for each I-Beam that came in, in a stack. Couldn’t find the majority straight edges off a layer, no, had to find only one beam at a time. That was a nightmare job. To make it worse, the I-Beams camexin from the outdoors after it could snow. Water reflects light, so we had to make sure all the beams are dried off completely. Lastly, the customer later.decided to clean and update their tin roof with clear plexiglass wavy things. Well, then the vision programs stopped working from sun up to sun down…vision systems are finicky little bitches!


  • Crazy shit. My boss had to pull someone lifeless out of a horizontal cnc mill. Doing the same procedure they both had done multiple times in the past. Except the guy accidentally triggered a sensor somewhere, which caused the machine to plunge a drill bit into the guy’s head. I am honestly surprised you can continue to work with automated equipment after something like that, it was just the other guy’s turn to do the procedure that day with my boss as assisting (way before he was my boss and we worked at the same company, so years ago). I guess if anything it explains his drive to making sure we are shipping out safe machines.


  • Robotics technician with 7 years under his belt here: these things only happen due to human error. Either at the integrators level (not the proper risk assessment made or poor programming/design) or by the worker (bypassing safety devices to get the job done). Now since this is South Korea, I don’t think they’d be bad off on providing safe machines in the first place. Since the robot unexpectedly moved, I’d have to guess the fence circuit of the robotic cell was jumped out in some way. Either by a hardwire jumper or taking the safety key off the door and jamming it in the receiving locking module. Normally when a safety circuit is broken (Emergency Stop, Fence/Gate/Light Curtain or Non-Teaching Enable Device) the robot has power to its servo motors disconnected physically.

    On the integrators side,.perhaps they didn’t interface a safety gate in with the robot, perhaps they didn’t use dual chain safety (24v line and a 0v line that flip at the same time and if they don’t flip within a certain time of another, safety trips due to the time discrepancy). Doesn’t say what brand of robot was being used, but the 4 types of robots I’ve used (fanuc, abb, motoman and kuka) have had force sensitive feedback to stop the robot in the event of a collision. But that’s a collision, so even a robot at 100% collision detection is going to do some damage before it stops, possibly could kill too if programmed poorly.

    There is a lot that can go wrong via human negligence of automated equipment. Having integrators and customers that understand the risks and practice good safety is vital to preventing workplace injuries on automated equipment! I’m proud to say the leading industry turnkey integrator I work for always has safety number one with our machines. Normally I would call BS if someone stated that, but we have almost endless checklists and design reviews geared towards safety. That’s what makes a great integrator standout from the mom and pop shops!
