I was watching "The Daily Show" with John Stewart last night and one of the guys was riding around in a Hummer Limo! The thing was MASSIVE.

His joke was that he kept running out of gas every mile or so

Hilarious stuff

More than useless, its unsound for any military to use. Way to easy to destroy and damage. Not to mention it will be severely limited in weapons...

Ah, the Land Walker. (http://www.sakakibara-kikai.co.jp/products/other/LW.htm)

Sadly it shuffles rather than walks, and it rather wobbles as it does shuffle. However, it's still very cool, and must have been a very tricky thing to engineer. As far as I can tell, the company's major purpose seems to be making machinery for handling bales of hay - talk about diversification!

Do you think it will bend at the knees high enough to step on a Hummer? :P

I can see a use for this... Entertainment. Imagine a paintball type of fragfest tournament with these bots. It'd be much more fun than using VR goggles or simulators. Instead of just being an amusement, it could become a real tournament with wagers or a prize. Perhaps it could be an all terrain race with teams that supply their own bots, or it could be a combination combat race, or capture the flag, team freeze, domination or regular frag-match.

If the teams can make their own design, that might speed along investment to make faster, more maneuverable bots. Imagine a special paintball or laser system that identifies a kill... the dead bot is immobile for several seconds or minutes with a flashing light indicating its status. After it comes back to life (respawns) it is invulnerable for several seconds or minutes to evade any "campers" waiting for it. All bots would have a set of wireless cameras for referees to monitor for enforcement of rules.

For real life, this might find use in riot-control the same way mounted police are more intimidating than officers on foot.

It was only a week or so ago that I was wondering when someone was going to built one of those things.

That seems fun, and the only practial use they would have.

Till it gets knocked over, then its useless

I'm curious, did they say where it was? I've seen one of those rolling around Sacramento a couple of times. You didn't used to see long/large limos here that often, but it is gettin pretty common these days. I have a hunch the Hummer version is popular as a novelty.

Till it gets knocked over, then its uselessAfter seeing the video, I'd agree. However, the concept may be valid with a properly designed ambulatory vehicle.

On a somewhat related note, last week I read a paper from 1992 that evaluated a six-legged walking machine. They called it an adaptive suspension vehicle (picture) (http://earth.kwangwoon.ac.kr/Robots/ASV.jpg). The researchers were testing its ability to maneuver around the forest as if it were a feller-buncher (http://www.osha.gov/SLTC/etools/logging/mechanical/fellerbuncher/fellerbuncher.html).

They concluded
The trials of the Adaptive Suspension Vehicle demonstrated that legged locomotion has potential for extending mechanized timber harvesting onto steeper slopes and softer soils while minimizing both erosion risk and disturbance of the forest soils. This potential should justify further development activities leading to the construction of a prototype more suitable for extended testing in forestry applications.
I don't know whether it was pursued any further, nor have I looked for more info on it.

I agree with Russ about that 2-legged thing looking like a solution in search of a problem.

It think I'll refrain from rushing out to buy one once it hits store shelves and jsut stick to my pedal-power bicycle...

Maybe I should just break down and take Drivers' ED... I could get my licence on the thirtieth of this June if i really wanted to. But I don't. Living in a small town means that school is a one-mile, ten minute bike ride. And school is on the other side of town...

yeah, I think I'll stick to pedal power... :D

That thing looks familiar. Weren't these first spotted on the ice planet Hoth? (http://giochiguerrestellari.andromedafree.it/trilogia/veicoli-robot/AT-ST.jpg)

They didn't say where it was. But it was white and the Daily show is based out of NYC, NY. So i doubt it.

Somebody in Finland seems to think that the problem is uneven forest floors. :-k

Meet the Walking Forest Machine (http://www.space.com/techtoday/tech_today_walker.html). The link they have now reroutes to John Deere who looks to be the parent company of Plustech.

They've spread that far north? Eep. The first time I saw one of those things my response was the same as the first time I saw an issue of Low Rider Bike- "only in L.A." #-o

Of course, I said the same thing the first time I saw an SUV stretch limo, so what do I know? :roll:

I saw a Hummer limo running around in Tampa last year. I know all the vets out in the rural areas of Florida bought regular Hummers for their practice when they first came out. And probably wrote it all off too.

I know my friends and I in the Army back in '88 were talking about fixing up a HMMV with A/C and the like long before Ahnold got one. We figured if we showed up at the motor pool with a tricked out HMMV, we could be made the battalion commander's driver in a heartbeat. :) Too bad we were poor SPCs, so Ahnold got there first.

Somebody in Finland seems to think that the problem is uneven forest floors.
There are several serious environmental problems that are addressed by a walking machine. In forest thinning operations, damage to residual trees and root systems is minimized by a machine that doesn't roll over the ground and has the ability to turn, move sideways, etc, without churning soil and bumping into trees meant to be left intact.

In clearcutting, soft, or weak soils (especially when wet) and their potential to be compacted or puddled is a serious problem that is being addressed in some jurisdictions by specifying limits on the amount of disturbance created during logging. There have been reams written on the issue (no kidding, my desk has a 3" stack of papers on this and related issues). In my neck of the woods, we are in the late stages of an enormous epidemic of mountain pine beetle (http://mpb.cfs.nrcan.gc.ca/biology/introduction_e.html). The result is that we are harvesting stands that are mostly dead and have greatly reduced rates of evapotranspiration (http://en.wikipedia.org/wiki/Evapotranspiration). The soils are wetter year-round, and more susceptible to damage by logging machinery. Even winter harvesting is more difficult because with the increased water content, soils are slower to freeze. So this is where that sort of technology would get more than raised-eyebrows attention. But that particular machine looks like it's being applied in a single grip harvesting (http://www.unb.ca/web/standint/nbcc/machine/harvesters/sdriz_a.html) role. I think our problem is greatest in the skidding phase, where heavy loads and high wheel torque really strain the soils.

Now, the real question is can this mech beat that mecha that crazy Alaskan guy is building, with flamethrowers in the arms, and nine-inch spike launchers in the shoulders? :lol: :o
