You could disable the motors. You can read out sensors without the arm moving. And if the arm needs to move, do it from a distance (cable connected or wireless).
A human shouldn’t be anywhere near moving robotic arms, ever.
The guy worked for the robot manufacturer, according to the article! You’d think would have been much more aware of the robot’s reach, and the safety procedures. Plus, I’m pretty sure you can step through the robot programming slowly. I’ve seen our programmers do it. Please don’t tell me he was in the cell standing next to the crate or whatever, with that thing running full production speed.
To be clear, you oft times can’t easily debug live code on a piece of machinery. Unless it was specifically designed to accommodate, 99/100 times it’ll be nigh impossible without digging in a soldering things to other things. And that is usually not something done on a factory floor.
A sensor issue on any machine, intelligent it not, is not justification to forgo a lock out, tag out of that machine.
It is like a shredder that only activates if something is in the hopper. If the sensor can only be accessed in the hopper, the shredder should not be operational when fixing the sensor.
