Not sure the robots help that much (apart from not dying when things go wrong).
As you said in some parts pressure is 1000atm, if we can pressurise the robots to 50atm that still leaves 950atm to deal with, I'm curious what happens to electronics at 100atm, 500atm and 1000atm. I'd imagine some components wouldn't handle that very well.
Of course robots have other huge advantages, duration (no messy waste problems, no need for oxygen/carbon dioxide handling systems, no need for (as much) heating) I guess.
- sp332 9y agoIt's a lot cheaper to keep a robot than a human operating at that pressure.
- IndrekR 9y agoIt is much easier to keep electronics working down there when empty space is filled with liquid instead of pressurised gas (usually nitrogen). It is not the pressure, but pressure difference, that matters and liquids are not as compressible as gas is. Edit: just adding a note that I have worked with submarine electronics[1] for a while and can say we even do not know much about what is happening near the shore, not to even talk about the unexploredness of oceans. Quite a lot of HW/SW in use by scientists is far from modern. We need more initiatives like the Ocean Discovery XPRIZE[2] to bring attention to the field.
