Best watercooling ever! [Archive]

This machine is a two stroke , air cooled (you can hear it, and its allso too lightweight for water cooling the engine)
its allso pneaumatic (you can see it with how it moves) so needs no hydraulic cooling.

But whats this? see the radiator on top? boy does that look familiar!
nothing would need cooling but the computer.

we all just ate it thanks to 10 million and darpa.

think of the computing power on that thing that has to be cooled.

watch they can kick it and it dosnt fall over!!!

and see how you can hear the fans when its running off the cord.
thats alot of computing.

It's not a toy, funding is provided by the DoD(Department of Defense) This is a weapon(potentially), at least that's the intent.

The Defense Advanced Research Projects Agency (DARPA) is the central research and development organization for the Department of Defense (DoD). It manages and directs selected basic and applied research and development projects for DoD, and pursues research and technology where risk and payoff are both very high and where success may provide dramatic advances for traditional military roles and missions.

Kinda scary if you really think about the possibilities and how close the realities of those possible applications are.

i feel so sorry for that thing when it gets kicked and slips on ice.

but yes that thing is wicked sick.

edit: @ OldSkool

You're just being a stick in the mud.

I worked at a company that contracted for DOD, Army, etc. They made all KINDS of cool crap. I can already see how one of the things we made could significantly help that beast, actually.

You can't tell me those guys aren't having a blast with that critter. It IS a 10 million dollar toy, no matter how you slice it. And yes, if it was loaded with guns n crap, it would still be a toy, just a toy for bigger boys LOL

I would just love to see how my dogs behaved around that thing LMAO

Oh by now means am I saying it isn't probably one of the coolest things ever and I'd trade some somewhat vital organs for the chance to play with it, It's just that at some point, you have to look at it for what it was meant to be. It's a seriously cool advance in robotics tho, no doubt.

Thats exactly what I meant.

A toy to the creators/designers

Ok I concur there, yes it will most likely be a very confusing weapon to the first few enemy targets that run into it haha. But while the innocence of it is still fresh, I want to see it as purely a childhood dream:santa:

Man, if a real live AT-AT were made, all the DoD would need to do for recruitment is have free movies days/nights with Star Wars Ep 6. I can just picture it:

When everyones walking out the theater, there will be the recruiters standing next to a big sign with the real live AT-AT pictured on it with the slogan: "Live the Movie" :beer:

What if it was armed and had sound detection for shots onboard? Then it hunted you down. :D

I wondered the whole time watching the video.
What are the electronics like in it? How long did it take to program it. Not just how do the legs work.

This would be very cool if it can be lightened up and used for exploration of other planets and such.

and yeah, i thought that too it must have taken a while for them to program it to balance and compensate if pushed.

but why the radiators? (can be seen in the slow-mo-ice-stumble) why watercool the computers?

if its a two stroke air cooled engine, and no hydraulic fluid needs cooling why not air cool the computers?

i mean it has to be one of the best examples of watercooling ive ever seen and has put what most of us have done to shame.

but you wonder why simple reliable air cooling (or even passive cooling) wasnt used?

Enablingwolf

That thing could have a lot of heat dump. The radiators might serve for more than one system on it.

synthetic_fenix

I would imagine they used watercooling to allow easier cooling of the computer components with them being on the same frame as the two stroke engine so there has got to be a bit of heat there.

its just a mechanical horse. how hard could it be?

a few computers, a few gyroscopes, an engine, an air compressor?

ohh, maybe the air compressors... but that would be oil cooled now - if i had to guess... but most of those are air cooled just like a 2 stroke.... it would be pretty rare to oil cool it.

i really wonder.

note you couldnt combine the computer cooling with anything else.
engines and pumps run way hotter than electronics.

The natural movement is actually fairly amazing, basically very clever programing.

with the best and brightest our country has (and a 10 million dollar question) its no sweat.

have a little faith.

they even watercooled the darned thing.

there is alot more potential out there than we realise.

i have no trouble taking this machine for granted.
find me someone who is to say it couldnt be done and ill show you 10 million and a few americans to prove you wrong.

its a beautifull thing.
i just cant get over how its cooled.
crazy, stupid, bold? i cant tell?!?!?

i dont say "wow, how futuristic!"

i say "its darned well about time!"

i dont say "wow, how futuristic!"

i say "its darned well about time!"

If something is in the here and now. To me it is not futuristic. The second part quoted did bring up a thought.

What was the crux of the project that held similar projects back so long? Robots are nothing new.. This one is not the same as others. It's not the shape. It is how fluid it was and stable walking..

Was it fast enough computers? Was it fast enough pumps? Construction materials? Was it heat that made it crash the computer system. The right programmer to finally come along and solve a logarithmic riddle? Or was it a certain type of gyro to push it to what it is now?

There is a lot of variables to consider. In complex machines. One itty bitty piece could of been the stump block for a long time.

Another thing.. Is the thing even able to run for longer than what we see in the clips before it crashes. Not just fuel load. Does it just go bonkers and they have to use the kill switch. Or does it overheat and kills it off until it cools down.

My wife had a hard time believing that was a machine. She wanted to saddle it and ride it though.

Wow, that really was incredible. I too felt bad when they kicked it as it had such a realistic "feel" to it. At first I thought it was some weird video editing of a dogs legs on some machine thing. They really did an incredible job with mimicking natural animal movement. And the way it reacts to the changing terrain is awesome. I mean when it slipped on the ice and corrected itself it looked so much like a real animal. I can see how these things could be very useful for military or even many other uses. Though I'd think they will have to strap a fuel cell driven electric motor on there or something because that huge-mongously loud engine wouldn't be so good for military troops trying to not make themselves known to enemies. :)

And I think I saw at least three different animals in that thing. I saw dog, horse, and goat movements. It's cool that they programmed at least three different behaviors in it. I wonder how many more. And I can't wait to see the biped version that makes me do a double take in thinking it's real human legs. :)

why Americans? Any bunch of humans from any part of the earth could do it, its just that the Americans have the will to make it happen.

I have to be honist, that thing scares the crap outta me, and only because I know all the US of A is going to is pack it up with guns.

Enablingwolf

Is there something wrong with advanced military research on robotics. Packing heat after it is tested and deployed? :rolleyes:

DARPA is Defense Advanced Research Project Agency

As soon as I seen it was a DARPA project. I knew it it meant to be a weapon of some sort. A very cool and scary weapon.

I could see this being first put to use as a pack mule for front line troops, and or as a recon device.

As a pack mule this could follow a squad carrying equipment, putting less burden on the soldiers, and extending their capabilities. This thing doesn't need ot have weapons mounted on it to mak eit a weapon. It would be an invaluable tool as a pack mule, a portable data center, electronic warfare station, portable sensor package, or some kind of combonation.
