Carnegie Melon reinvents the wheel with shape-shifting tech


Impressive new technology has emerged that can transform a wheel into an all-terrain track in just two seconds.

The invention is being developed for the U.S. military, to make it easier for their vehicles to tackle different driving surfaces.

Created by the Carnegie Melon University National Robotics Engineering Center, the device would mean vehicles can transfer from hard to soft ground instantly without even having to slow down.

Called the "Reconfigurable Wheel Track" (RWT), it starts off round and uses a thin rubber cover over a robotic wheel.

COMMENT:-

Nothing world shattering here, but it is an interesting development.

PS - The "Maintainers" are going to be absolutely "ecstatic" if this ever gets through testing and development enough to actually survive field reliability testing (which I doubt).

Why use a $ 10 000 dollar wheel when you can get a $ 200 000 dollar one that is less reliable?
I expect the US army to switch over all wheeled vehicles starting in 2023

This is not what the term "reinventing the wheel" means. Reinventing the wheel is a phrase that refers to a person laboriously and unnecessarily recreating something that has already been made and well understood for many, many years.

Fox News would have been more accurate if they had said "Reimagine the wheel" or "Revolutionize the wheel."

I tend toward "gilded the lily" myself.

I personally wish they'd used the expression fixed what's not broken. It still would have been more accurate than reinventing the wheel.

Headline is bull****.

This is inventing an alternative to wheel, potentially a better option in some cases.

Not the same thing again, as the phrase means.

I mean, I know they were maybe going for a bad pun or something, but...

They frequently are (at least in the sense of "doesn't actually describe what's actually in the article").

This is inventing an alternative to wheel, potentially a better option in some cases.

"Track" has always been an "alternative to wheel" and what Carnegie Mellon actually did was to develop a "re-configurable track race".

The only problem with "track" is that it breaks down one hell of a lot more frequently that wheels do (and what Carnegie Mellon did was to produce something with one hell of a lot more moving parts than a wheel has).

The technical term is "grabber".

Could potentially be useful in some very specific circumstances as long as it lasts at least a little while?

One would hope but if the pentagon gets involved, then expect potentially many billion$ going into this just on the concept and yes,
whether it works now or not or even billion$ later...it doesn't matter.

Don't count it out. This could prove to be another great meal ticket for the MIC (military indust. complex) like SDI, more aircraft carriers and junk destroyers..

The for-profit defense (war) machine is alive and well and once again will truly show us just how...the pentagon works.

Mostly bureaucratic [rank] sustenance having twice as many generals as it took to conduct WWII on two fronts, and a whopping profit center.

Indeed it "could".

The kicker is in the "as long as it lasts at least a little while".
 
It won't be functional at anything over 35 mph, on ANY terrain.
 
A minor detail that can easily be resolved if the US government invests a couple of billion dollars in R&D.

Tracked wheel mfrs have already been investing similar amounts in R&D since WW2.
They reached the conclusion that on hard asphalt and concrete road surfaces, rubber tracked wheel longevity on vehicles in the 1-2 ton class is seriously shortened at anything above appr. 30-35 mph.

There are other quick change solutions that perform much better for conventional wheeled vehicles.

Hub mounted system from RU/EU

OnSpot Automatic Tire Chains

That's just two examples.

Sorry, I wasn't clear enough. That should have been A minor detail that can easily be resolved if the US government invests a couple of billion dollars of government money in R&D.".(change emphasized)

LOL but hey, every once in a while Uncle Sam gets it right.

The NASA space race to the Moon generated the single largest and most important technological leap forward in the history of the human race.
Everything you use today that uses a microprocessor exists because we needed microprocessors to be able to make it to the Moon.
Even TELEVISION VIDEOTAPE editing was made feasible by the EECO On-Time Telemetry Management System's "time code" because television's S.M.P.T.E. time code was taken from EECO.
Had NASA NOT leveraged microprocessor technology so heavily, and stayed with transistors and vacuum tubes, we might have still made it to the Moon eventually, however it would have been much more costly and much more dangerous.
Microprocessors still would have been invented anyway but their path to that of a very cheap resource for consumer electronics would have been delayed by as much as a decade or more, the way they were delayed in the USSR and later, Russia...which only began catching up in consumer microprocessor electronics around the middle of the 1990's.

It was the government "heavy lifting" that gave PRIVATE INDUSTRY the boost and the shot in the arm that it needed to get them to market that much faster, because government investment in economies of scale and manufacturing was a huge boost and a cushion against R&D overhead.

Agreed.

Of course if you want to pay all of my R&D costs then I can develop a whole lot of things.

Admittedly the progress from having five or six TV channels (two or three of probably had something that I wanted to watch) to having three or four hundred TV channels (one or two of which might have something that I wanted to watch) CAN be described as "progress" - as can the ability of people to spread falsehoods and derogatory comments through the Internet faster and further than they ever could before.

LOL, you're not the first one to complain about Marshall MacLuhan's vast wasteland getting an injection of high tech steroids.
The techies only create the machinery, they're not known for being able to create CONTENT.
That is up to the artists and the journos.

As you know, it's not about the number of channels. I wasn't referring to a larger transmission spectrum, I was referring to the quality of the transmission infrastructure and the nodes that inhabit it.

We've gone from a tiny, unstable AM analog radio signal transmitting a crude facsimile of narrowband analog video information to bit for bit digital clones of 4K resolution digital cinema and eight channel wideband audio. The tiny cyan colored square at the lower left is what old NTSC analog television gave us. The gigantic pink rectangle (4K DCI) that dominates is what we're capable of receiving today.

And that's just television.
Your smartphone contains more computing power than ALL of NASA's entire computer infrastructure in June 1969, when we first set foot on The Moon.

I will agree that, not only have we but more chrome on the Yugo, but that it's much better chrome too.

PS - It doesn't matter what wonderful stuff the writers and/or artists and/or journalists come up with, IF the people who own the means of distribution don't think that there is any money to be made out of it THEN it tends to sit in the box.

Can you think of a single network TV cartoon program that is as fast paced and "literate" as "Rocky and Bullwinkle"?

How many of the High School graduates that you know can read


* * * They looked round on every side, and hope gave way before the scene of desolation. Immense branches were shivered from the largest trees; small ones were entirely stripped of their leaves; the long grass was bowed to the earth; the waters were whirled in eddies out of the little rivulets; birds, leaving their nests to seek shelter in the crevices of the rocks, unable to stem the driving air, flapped their wings and fell upon the earth; the frightened animals of the plain, almost suffocated by the impetuosity of the wind, sought safety and found destruction; some of the largest trees were torn up by the roots; the sluices of the mountains were filled, and innumerable torrents rushed down the before empty gullies. The heavens now open, and the lightning and thunder contend with the horrors of the wind.

In a moment, all was again hushed. Dead silence succeeded the bellow of the thunder, the roar of the wind, the rush of the waters, the moaning of the beasts, the screaming of the birds. Nothing was heard save the plash of the agitated lake, as it beat up against the black rocks which girt it in. Again, greater darkness enveloped the trembling earth. Anon, the heavens were rent with lightning, which nothing could have quenched but the descending deluge. Cataracts poured down from the lowering firmament. For an instant, the horses dashed madly forward; beast and rider blinded and stifled by the gushing rain, and gasping for breath. Shelter was nowhere. The quivering beasts reared, and snorted, and sank upon their knees, dismounting their riders.

He had scarcely spoken, when there burst forth a terrific noise, they knew not what; a rush, they could not understand; a vibration which shook them on their horses. Every terror sank before the roar of the cataract. It seemed that the mighty mountain, unable to support its weight of waters, shook to the foundation. A lake had burst upon its summit, and the cataract became a falling ocean. The source of the great deep appeared to be discharging itself over the range of mountains; the great gray peak tottered on its foundation!--It shook!--it fell! and buried in its ruins the castle, the village, and the bridge!

I get where you're coming from. All of us should have THAT DISCUSSION.
I don't know if it would gain traction in this thread but it's a worthwhile discussion, no question about it.

PS: I think Family Guy, South Park and Futurama are pretty sophisticated. Maybe not on the level of Rocky and Bullwinkle but Seth knows how to punch an edgy topic and put it in a cartoon, and Mike Judge and Matt Groening are no slouches.

Your link dropped out.

You might find THIS THREAD interesting.
 
Regarding "This thread: (I never said that!)"
YES, I have been aware of that technology for quite a while because I actually USED a tiny bit of that exact technology to make my own 1972 Leon Russell concert video sync up where sync never even existed in the original damaged 50 year old video recordings.

To date, not even the surviving original musicians who played on that stage are able to tell where I applied it either.



Yes, it even works with music.
No, it's not like I applied it throughout the entire show, but I did make use of it to patch problem areas because the original videotapes were recorded improperly to begin with, and there are massive sync problems here and there all throughout the entire two hour show.
That plus the tapes were almost 50 years old and very damaged.

AND YES, it's frightening as Hell when it is used in legal and political realms!
 
Sorry about that. It looked like it should have been a link.

My fault.

I rebuilt almost all of the dialogue segments of the Leon show, where he's introducing the band or talking to the audience, and I stitched together vocals from other recordings on other reels from the tour using two different versions of that technology.
