Could this be the beginnings of a wall-painting robot?
Painting is a tedious task and now that there is a wall climbing robot, I say duct tape a paintbrush to its ass!!
I hate it when people think they know what they're talking about. For dives I make to 300' on open circuit scuba, I'll often wear 6 or 7 tanks with the proper mixes. I don't do little bounce dives to 300, I do exploration dives with 20-30 minutes at that depth.
BTW, a standard scuba tank lasts me 15 minutes at 200 ft, much more than just a bounce dive.
If you hear a boat or jetski while trying to make an ascent, you can't possibly choose a safe spot, since it is impossible to tell what direction the noise is coming from.
Perhaps they just haven't considered the possibiliies that the bone conductive technology offers them.
A scuba diver shouldn't put headphones in the ear, since the water pressure could force them into the ear causing damage (much the same reason a diver can't use ear plugs). With this bone conductive technology you could eliminate that problem.
I'd imagine that all that would have to be done is to put the player in a pressure vessel, much like the underwater housings used for video cameras.
I'm in the military electronics industry and our company makes UAV's (the unmanned air vehicles) you mention. I don't work on the UAV project at all though.
UAV's are much simpler than land based, since they don't negotiate rough terrain, they just fly over it.
Even with something as simple as UAV's, it's very tough to get all the required electronics, photo, sensors, etc into a small enough package so that it can be deployed easily by ground troops anywhere.
BTW, UAV's can certainly be used for more than recon...
I gave a very simplistic explanation, partially because it is correct, and partially because I'm not a geo-expert.
Essentially, there are things underground that cool the temperature quite a bit, such as ice cold springs, waterfalls, etc. The rest of my explanation is correct - too far from the sun, and WAY too far from hot molten lava to increase the temperature.
Yes, there are much larger cave systems (like many in Mexico, Florida, Australia, and even one in Canada that I can think of), but that doesn't necessarily reflect on the distance travelled on a particular cave push. 4km is far to travel in a cave when you have to crawl and sqeeze through tight passages and be able to retrace your route out. You need to carry supplies and many lights. So yes, 18000' (about 4km) seems pretty far to me.
Here is the link http://www.wkpp.org/ to the previous group's world record. They were diving a cave system in Northern Florida at a depth of 300' doing a horizontal penetration of about 18000'. It took 6 hours to do the round trip and it resulted in 9 hours of decompression stops.
Interestingly enough, the longest cave penetration was made in a completely flooded cave using scuba (rebreathers). They are the EKPP http://www.ekpp.de/projects/doux02/index.html.
" Everybody has to know their own limits as far a nitrogen narcosis goes" is just ridiculous.
It's like me saying that I feel comfortable driving after 7 beers, but everyone has a different limit.
Don't drive impaired and don't dive impaired. It's that simple. Helium is a nicer gas to decompress from. It does less damage to your body than nitrogen. There is less breathing resistance at depth so you don't have to use regs with high IP's to get good performance. It provides mental clarity necessary to do deeper dives. You feel better after diving high helium.
As far as 60m ok for O2 toxitiy, you're pushing it IMO. We don't dive ppo2's of 1.4+ on the bottom. We dive ppo2's of closer 1.0 or 1.1. You're already going to be giving your lungs a beating with high ppo2's on deco, so we don't do it on the bottom.
The stuff you're saying sounds like from a TDI or IANTD manual. Just because those agencies recommend it, it doesn't mean that it is the best option.

BTW, diving to 59m on air is a delusion of safety.
Better to dive trimix for any dive below 30m. It increases your cognitive faculties so much that it's worth the extra cost. I also feel better after a helium dive than an air/nitrox dive to shallow depths.
I hate the feeling of being impaired while I dive. A 30/30 (30% oxygen, 30% helium) is a great mix for 30m. Between that and 60m, I dive 21/35. I follow all of GUE's standard mixes
Just as I wouldn't drive drunk, I would't dive deep on air.
Anyone who does "technical" diving knows that computers are completely inadequate for the job.
You can plan multi-level dives using software the same way you generate deco schedules for your tech dives.
A dive computer is merely a crutch for those that don't understand decompression. It promotes diving without adequately planning your dive. It can produce very unsafe schedules especially for bounce dives by saying that no deco is needed when you clearly need some. Not if, but when it fails, the user is left without a proper understanding of deco, and they are left doing an ascent without confidence that they will come out of the water safely.
The problem with dive organizations like PADI (Put Another Dollar In;-) is that they certify divers with ego-boosting titles like Dive-Master or Mater-Scuba Instructor and they have a TON of useless certifications like Boat Diver. What's next, Knife Diver? Advanced Knife Diver with the 6" blade specialty? The problem is that a Master Scuba Knife Diving Instructor who doesn't understand deco himself tells his students that they need a dive computer. Who can say 'NO' to this Knife Diving GOD? Now you have a ton of divers who don't understand deco enough to recognize when their overpriced dive computer (which is less reliable than Win 98) gives out bad information.
The only computer I trust while diving is my brain.
"Proper diving procedure" recommends not trusting a dive computer, but rather planning your dive before hand using some of the many software programs out there, and having your dive plan/schedule known before hand. Monitor your dive plan while underwater while using a depth gauge and bottom timer, instead of a complex, convoluted computer.
Computers are prone to fail underwater - bateries die, oring seals fail, and it's just a harsh environment in which to be trusting electronics.
To further complicate the problem, the bulhmann model that the computer uses produces horrible decompression stops. There are other decompression algorithms out there that produce much nicer shapes of decompression, like Eric Maiken's VPM (Varrying Permability Model).
To make matters worse, none of these algorithms truly model what is happenning inside the body - for example, they completely overlook the biochemical aspect of the dive.
We produce dive schedules using software, then massage the schedule to start the decompression stops deeper, extent time on any gas switch, and then shorten the shallow stops considerably. I did this just yesterday will doing deep dives on trimix (helium-based mix with lower oxygen content) while looking for new wrecks in the shipping channel.
Trusting a dive computer is insanity - use your brain instead.

Cool, but how deep will it go? Can I bring it on a 300' deep scuba dive to entertain me during hours of long decompression stops?

It isn't a remote control car. It has AI to make the decisions instead of someone controlling it remotely.
When amateurs begin to do it for profit, they become pros.

It's so cold because you get no sunlight to heat things up, yet you are so far from the centre of earth that the molten lava can't warm you either.
No, I can only find Area 51A.
