MIT Robot Walks On Water
An anonymous reader writes "Researchers at MIT have solved the
mystery of how water striders propel themselves across water surfaces and in the
process have created a robot called Robostrider
that mimics the behavior. With cool stuff like this, it's no wonder
MIT is number one in engineering."
Can it turn that water into wine?
C - A language that combines the speed of assembly with the ease of use of assembly.
Actually there are several people who thing that MIT's direction in AI has gone seriously awry. Marvin Minsky (though somewhat stodgy), has pointed out that MIT's focus in robotics is no longer on figuring out how to make things that do stuff for people, but on subhuman gadgets.
So, yeah they may be number one, but in a way, they've let down the old guard of AI researchers.
Still, this is quite cool.
There are lives at stake here!
If the water's polluted enough, anyone can walk on it.
The coolest voice ever.
... somebody will soon use the word 'overlords', and it won't really be funny.

it's no mystery as to how they stay afloat. the big question was how they propel themselves
BSD is for people who love UNIX. Linux is for those who hate Microsoft.
The question is about propulsion, not weight-to-surface tension ratios sufficient for flotation. This research gives a better explanation of the mechanism by which the water skimmers move with such great efficiency (namely by created subsurface vortices with their middle pair of legs) and puts to rest the notion that it is attributable to the waves themselves created by a rowing action.
MIT is number one in engineering.
Robostrider is made out of a 7-Up can, stainless steel wire legs and an elastic band coupled to a pulley to power its middle legs.
Too much 7-Up and not enough beer being consumed for it to be a fair contest. They should increase their beer consumption to that of other colleges and level the playing field.

Just the interesting ones. :)
You can skip the SCO-soap-opera updates and other fluff, but make sure you keep up to date with the ROBOTS, man, or they'll take over!

If it can walk on water - does it run on linux?
Charles river (the river that MIT stands on) is always covered by a film of oil which is approximately one inch thick. You don't have to be a freaking rocket scientist to build a robot which walks on *that*.
I passed the Turing test.
You see, science is not about only making big breakthoughs on things in you direct field of interest. A lot of it is small discoveries, that are used down the road in ways that people didn't think of when they made the discovery.
I'm sure no one could possibly know yet. How is grinding little pieces of glass to play with light and images going to help anyone? (He writes while wearing corrective lenses.)

It's much to early to tell how this will help us build better boats or water based technologies. If we already knew how to apply the technology, we wouldn't be researching to understand the science of what makes it work.
end of line
The scale of water bugs goes from .5" to 10", its more of a function of keeping the surface area of the 'legs' in proportion with the weight and balance of the rest of the body.

Someone has blotted out the intimate details of the waterstriders mating ritual. Is he seriously worried about offending someone, or is he worried about hosting a porn site? Who says political correctness has gone wrong... This is just pathetic.
...small discoveries, that are used down the road in ways that people didn't think of...
Excellent point. Sex toys and porn were not on the minds of the engineers when they were developing their respective techn...
Awwr, who the hell am I trying to kid?

I'm not sure what would bother me more to see upclose in the pool, a Vietnamese Water Strider, or a 7-Up can with legs...

What does this have to do with AI?
The research reported on is primarily about fluid dynamics. Robostrider is a catchy thing they've created to bring attention to the important findings. In fact, seeing as the strider is powered by a rubber band, not only does it not have anything to do with AI, it has nothing to do with robotics either.
This doesn't mean it's not wicked cool.

Everywhere else it's known as RoboAragorn.

Researchers at MIT have solved the mystery of how teenage boys satisfy themselves several times daily and in the process have created a robot called Robostroker that mimics the behavior.

It doesn't matter, I'd hire this person to the exclusion of his peers at MIT. Why? It's creative, I didn't think about it, and I can use someone whose brain works like that.
I can hire coders & designers easily. They're a dime a dozen. I can hire GOOD -> excellent coders or designers more difficultly by talking to friends of friends etc, but they exist and are plentiful enough. To hire someone that will build a rediculous thing that no one has really seen before, carry that design through to completion, and make headlines...that person I'd pay a lot of money to. He'll make me filthy rich if I'm nice to him.
You do realize that the space program started with unmanned craft, then insects, perhaps mice, then on to monkeys, and then Purdue graduates....
