Walking on water? (0, Redundant)

I for one welcome our new water-walking robotic overlords.

This is a crock of shit (4, Informative)

EmbeddedJanitor (597831) | more than 6 years ago | (#21644679)

This is not science. This is bullshit.

The "robot" spreads its weight out using the whole length of its legs in contact with the water. That is nothing like a water strider.

A water strider walks on the **ends** of its legs (feet, if you will). For a far better description see http://www.livescience.com/animals/041103_water_strider.html [livescience.com] .

The only similarity is that they both use surface tension.

PolarBearFire (1176791) | more than 6 years ago | (#21645107)

I have trouble disagreeing with you. I looked at the pic expecting a robot analog of a water strider. Instead it was really disappointing. You can get the same exact effect using a common paper clip on a cup of water! Maybe I can attach a small motor to it and call it a water bouncing robot. I got to tell you man, these scientists are seriously making the 21st century suck.

dotancohen (1015143) | more than 6 years ago | (#21645981)

It's science for the headlines. NASA pioneered it by sending humans where robots should go, albeit at a time when it was appropriate (space race). Remember these assholes? [slashdot.org] Making up 2.5 meter scorpions from a 46 centimeter claw. Assuming the claw-body ratio of modern scorpions, that would still make for an impressive 1.75 meter scorpion. But no, these idiots had to exaggerate, to break records. Science is being perverted. Bah.

Speculation, speculation (1)

EmbeddedJanitor (597831) | more than 6 years ago | (#21646979)

Of all the so-called sciences, paleontology has to be the most contrived.

Modern scorpions do not have a fixed claw-to-body ratio. Non-poisonous scorpions tend to have larger more powerful claws, sometimes by a factor of 3 or more. Using modern claw to body ratios would give a size of somewhere between approx 1.5 and 5 metres. Of course that assumes that claw-to-body ratios have been constant over time.

One just needs to look at the fiddler crab to see how stupid it is to make claw-to-body comparisons and such assumptions. The fiddler crab has two different size claws, one approximately the width of the crab and the smaller one approx 20% the width of the crab.

Still, the giant scorpion is far less contrived than many paneontological "discoveries". You often see beautifully detailed drawings and descriptions of animals with the only physical evidence being a tooth fragment.

I'm gonna take a guess to say that you learned this from Mr. Wizard [mrwizardstudios.com] ?

I remember this episode well - it is a simple but very awe-inspiring (at least from a geek's perspective) experiment. It goes like this:

      1) Fill a cookie tray with water
      2) Pepper the top of the water in order to *see* the movements of the surface tension
      3) Carefully place a small amount of soap in the center of the tray
      4) Watch the pepper scatter to the edges of the pan as the tension breaks

If you have a kid, then you need to go do this experiment with them NOW!

Create a "boat" out of aluminum foil. Shape it like a square with a triangle appended to one edge, and fold slightly. Cut a small slit on the back of it (opposite the point), and place carefully on the surface of the pan filled with water. Carefully place a small drop of dish soap onto the slit, and watch the surface tension propel your boat forward!

The Picture Might Be Worth It... (3, Interesting)

javelinco (652113) | more than 6 years ago | (#21644317)

But I believe we've had a theory for this for awhile now. In August of 2003, MIT published some information on the subject. Here's a link:

http://web.mit.edu/newsoffice/2003/robostrider.html [mit.edu]

Here's some relevant content from that link:

MIT researchers report in the Aug. 7 issue of Nature that they now understand how the insects known as water striders skim effortlessly across the surface of ponds and oceans.

And:

Using mathematics, high-speed photography and a variety of flow visualization techniques, Bush, mathematics graduate student David L. Hu and mechanical engineering graduate student Brian Chan uncovered the true way in which water striders walk on water.

As the insect rests on the surface, the tips of its thin legs create miniscule valleys. It sculls the middle set of its three pairs of legs like oars, causing the water behind those legs to propel it forward as the surface of the valley rebounds like a trampoline. Although the rowing motion does create tiny waves, "the waves do not play a significant role in the momentum transfer necessary for propulsion," the researchers wrote. "The momentum transfer is primarily in the form of subsurface vortices."

Re:The Picture Might Be Worth It... (2, Interesting)

javelinco (652113) | more than 6 years ago | (#21644413)

Article Content (even Google cache is REALLY slow):

The way water striders walk on water was discovered years ago. The insect uses its long legs to help evenly distribute its tiny body weight. The weight is distributed over a large area so that the fragile skin formed by surface tension supports the bug on the water. However, the ability of water striders to jump onto water without sinking has baffled scientists, until now.

A team of researchers at Seoul National University, led by Ho-Young Kim and Duck-Gyu Lee, has finally answered that question. By using a highly water-repellent sphere, which mimicked the actions of the water strider's highly water-repellent legs, they were able to determine a small range of speeds at which the sphere or insect could hit the water and not sink.

If the sphere hit too fast, it would shoot through the surface of the water. If it hit too slow, it would not bounce back and sink. The water strider is one of the fastest moving insects in the world. It can travel up to 100 times the length of its body in one second, equivalent to around 400 mph in human terms.

Scientists hope to adapt this technology to the obvious sector; creepy sounding robots. One team at Carnegie Mellon University has already developed a small spider robot that can walk on water like the strider.

The Korean scientists believe their discovery will help create robots that can travel over still bodies of water. They say the robots can be used to explore or monitor water quality. Also they could, and it's highly likely that they will, be used as a form of spy robot.

While this is all well and good, and a touch unnerving since it reminds me of several scary sci-fi books, I'll be a lot more interested when they invent something that allows humans to walk on water this quickly.

Here's a related link: http://www.livescience.com/animals/041103_water_strider.html [livescience.com]

This one is erroneous in at least one way. It suggests that tiny bubbles trapped in hairs on the bug's legs make it float. Tosh! The bubbles are too small to make it boyant. What the bubbles do is increase the surface area which, in turn, increases the amount of surface tension "skin" that the bug walks on and therefore the carrying capacity.

As most fly fishermen would tell you, surface tension is far stronger than you'd think. Hatching bugs struggle to get through the surface tension which keeps them under the surface. Once they break through they are able to sit and walk quite easily.

The traffic isn't that bad. We just had to talk to them a bit about caches and linking directly to dynamic pages. We also temporarily raised the caps on their virtual server and adjusted the Apache configuration for this type of traffic.

which is likely what we'll be coming across, as opposed to water, the way things are going. will the 'robots' be able to 'bounce' on acidic goop?

corepirate nazi execrable costs outweigh benefits
(Score:-)mynuts won, the king is a fink)
by ourselves on everyday 24/7

as there are no benefits, just more&more death/debt & disruption.

fortunately there's an 'army' of light bringers, coming yOUR way

do not be afraid/dismayed, it is the way it was meant to be.

the little ones/innocents must/will be protected.

after the big flash, ALL of yOUR imaginary 'borders' may blur a bit?

for each of the creators' innocents harmed (in any way), there is a debt that must/will be repaid by you/us, as the perpetrators/minions of unprecedented evile, will not be available.

all is not lost/forgotten/forgiven.

no need to fret (unless you're associated/joined at the hype with, unprecedented evile), it's all just a part of the creators' wwwildly popular, newclear powered, planet/population rescue initiative/mandate.

or, is it (literally) ground hog (as in dead meat) day, again? many of US are obviously not interested in/aware of how we appear (which is whoreabull) from the other side of the 'lens', or even from across the oceans.

vote with (what's left in) yOUR wallet. help bring an end to unprecedented evile's manifestation through yOUR owned felonious corepirate nazi glowbull warmongering execrable.

some of US should consider ourselves very fortunate to be among those scheduled to survive after the big flash/implementation of the creators' wwwildly popular planet/population rescue initiative/mandate.

it's right in the manual, 'world without end', etc....

as we all ?know?, change is inevitable, & denying/ignoring gravity, logic, morality, etc..., is only possible, on a temporary basis.

concern about the course of events that will occur should the life0cidal execrable fail to be intervened upon is in order.

'do not be dismayed' (also from the manual). however, it's ok/recommended, to not attempt to live under/accept, fauxking nazi felon greed/fear/ego based pr ?firm? scriptdead mindphuking hypenosys.

consult with/trust in yOUR creators. providing more than enough of everything for everyone (without any distracting/spiritdead personal gain motives), whilst badtolling unprecedented evile, using an unlimited supply of newclear power, since/until forever. see you there?

"If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land."

This will fail to be commercially deployed. (1)

I hunted for the video. In my search I came upon the original site, not the article talking about the site.

http://nanolab.me.cmu.edu/projects/waterstrider/ [cmu.edu]

Here is the actual project including how it works (Pizo) photos of both prototypes, the light and dark one, and detail on the robotics in it.
It includes 3 videos including the walking on water video.

Water Striders... (2, Interesting)

homgran (766092) | more than 6 years ago | (#21645097)

I remember going to a conference presentation by John Bush [mit.edu] back in 2005 which detailed the physics behind water striders. His presentation was very good, and the video footage he presented was absolutely fantastic (see here [mit.edu] and here [mit.edu] ). I think the work referenced in the main article isn't quite as groundbreaking as they'd have you believe. There has been quite a lot of work in this area over the last five years.

So how do the striders do it? (0)

Anonymous Coward | more than 6 years ago | (#21645655)

I wonder how they control the the speed at which they hit the water? Wings? Do they use their legs as shock absorbers?

That picture is not actually from the new research, it is from old work at Carnegie-Mellon. Here is a bigger version:

It is part of the work of the NanoRobotics Labaratory [cmu.edu] at CMU.

Wouldn't a little boat be just as efficient (if not more) without all of the robot research.
