  • It’s a very good lesson- to the point where I wouldn’t be surprised if the teacher is deliberately putting an arbitrary restriction on the assignment.

    If you want to have a career, the people that pay you are going to make you do things that you consider to be ridiculous. That’s work, that’s life. You’ve got three options- Just smile and nod and do it their way, get huffy and tell them that you don’t like their yapping and you’ll do their project your own way, or politely suggest there may be an alternative way, and ask if they are willing to be flexible with some requirements.





  • Have a look at the Bananapi options, especially the R3. (Or the R2, it’s a bit more mature)

    It’s a very capable single board computer with onboard managed switch, including SFP cages. If you want, you can buy antennas and utilise the wifi 6, or get a dedicated access point.

    PFsense, openwrt, et al all have images. I think some people also run the mikrotik OS on it. It’s powerful enough to run as a hypervisor so you can chop and change between all of these if you want.

    It gets bonus points for accepting 5G modems for failover.



  • Without knowing the setup, it’s all guesswork- But if I had to guess, the program the robot ran through would be a series of movements that results in a box that is this size and this shape in this position being moved perfectly well to this particular spot.

    Humans are not that size, that shape, or in that position.

    I’ve not worked industrial in Asia, but where I have worked there has been stringent protocols around locking out machinery that has the potential to kill. For someone to enter a hazardous area, they have to remove any potential source of energy (eg, disconnecting power to motors, draining hydraulic pressure, lowering suspended loads, etc) and use a lock that only they have access to to prevent that energy returning. I’m guessing that this incident either did not have that procedure in place, or it was in place but not followed correctly.
