Gecko Feet Inspire Hand-Held Spider-Man Paddles

samzenpus posted about 4 months ago | from the wall-crawler dept.

The Military 64

ygslash (893445) writes DARPA is developing hand-held paddles that can be used to scale vertical walls. The adhesion technology employed in the paddles is based on Van der Waals force, inspired by the feet of certain species of geckos known for their excellent climbing ability. In a recent test, a man weighing almost 100 kg (220 lbs) and carrying a heavy pack that added about 23 kg (50 lbs) of additional weight, was able to scale a vertical glass wall almost 8 m (25 ft) high using the paddles. However, the paddles are reported to be 'not battlefield-ready yet.'

Taking inspiration from the movies (1)

I see someone at DARPA is a fan of Mission: Impossible [yahoo.com] .

Cool concept though, and pretty useful for firefighters I'd imagine.

For fighting an actual fire, I wouldn't want to be so precarious. For rescue work though...and how would it hold up under wet conditions, say, a boat?

Re:Taking inspiration from the movies (2)

dbIII (701233) | about 4 months ago | (#47219821)

Probably not well at all. A relative sprays geckos with insect spray to make them fall off the ceiling. Since the poison is unlikely to act quickly (or probably not at all on a reptile), it's likely to be the propellant getting under their feet. It's not much good sticking to a liquid instead of the wall under the liquid.

Re:Taking inspiration from the movies (1)

aevan (903814) | about 4 months ago | (#47220147)

Ah, figured. There goes that idea. Still, likely some unconventional uses for them out there.

Re:Taking inspiration from the movies (1)

dbIII (701233) | about 4 months ago | (#47220783)

On the other hand in combination with something that drives liquid away from where you want the stuff to stick may deliver possibilities. Since it's on a microscopic scale combining the fibres that stick on the ends with fibres that wick stuff up, channels for air to flow or whatever may not be hard to do.

It will be good to get some use out of the force that makes the conventional idea of nanomachines difficult or impossible (eg. tiny little gears will stick together instead of working like gears above the micro scale so Drexler's dream isn't happening - it has to be done in a different way which will not look like conventional mechanical devices).

I was thinking of the surviving victums of the Twin Towers Event. Could this device be useful to those above the crash site? How about a cable that allows folks to hold on to? I'm not a soldier, but I don't think that climbing glass walls is a typical combat mission; maybe for the specialty missions?

There was also walking on water like some lizards and insects do, but no not quite similar.

Van der Waals force isn't exactly a myth though, just a job for materials science.

kenwd0elq (985465) | about 4 months ago | (#47219425)

The problem with trying to USE Van der Waals forces for anything is that in order to stick together, both surfaces must be microscopically smooth; the sort of "smooth" that would make plate glass or mirrors look like "volcanic rock under a magnifying glass". "Reflecting telescope mirror" smooth. Making materials that smooth - and KEEPING them that smooth - is going to be a challenge.

As physics, it's pretty neat. From an engineering perspective, it's going to be a problem.

Re:Uh Oh! Here comes Iron Man (3, Informative)

dbIII (701233) | about 4 months ago | (#47219833)

both surfaces must be microscopically smooth

Not as such - as seen in the summary where geckos are mentioned. One side is made up of a LOT of very smooth surfaces of microscopic size which gets around the problem.

From an engineering perspective, it's going to be a problem

Which has been worked on for decades and is paying off now with a few different things - I think another is called "gecko tape".

Save 45% by joining AAA.

**Off Topic**

If you ever need towing, call AAA, join the club, and then use the towing feature. It's cheaper than calling a wrecker directly (and you're not dealing with some fly-by-night who may just steal and/or wreck your car), and now you've got access to free maps and frequently better travel deals than you can find online. As AAA members we save enough on insurance to pay for the membership every year.

Glass is incredibly hydrophilic (1)

So glass loves water and anything else prone to Van der Waals forces.

Re:Glass is incredibly hydrophilic (2)

SuiteSisterMary (123932) | about 4 months ago | (#47221557)

My understanding is that the technology works poorly on dusty surfaces, due to the setae sticking to the dust rather than the surface, but the only surface that absolutely won't work is Teflon.

Re:'not battlefield-ready yet' (0)

Anonymous Coward | about 4 months ago | (#47220481)

No it means that once you take the paddles out from cover, they are so full of dust that you can't use them anymore.

This isn't a new innovation or new product. People have done these with on-market products what are used to hold your smartphones, wallets etc on car dashboard etc. They are size of 7x12cm and cheap as hell. All what you need to do is to stitch one to glow and add glue to secure it and you have this amazing "spider man" capability to climb up glass wall.

The real problem is, there is no glass walls what can hold heavy weight as they get shattered to pieces and typical walls are made from totally different material and they usually have a ladders on them or something similar.

And if you have squad of 4-men you can climb up over 7 meter heights faster than using these paddles.
