A Robot That Runs On A Sugar High

Digitalia writes: "Using a biological soup that mimics our stomachs, the gastrobot is the first commercial robot that "feeds" on organic matter to get its energy. Chew Chew, as it is called, takes a cube of sugar and turns it into enough energy to roll around for 15 minutes. I particularly enjoyed the creator's explanation as to why his bots aren't carnivores. Check the article out here." 15 minutes seems a pretty good run for a sugar-cube, but hasn't anyone explained the carbohydrates theory to this robot?

There is a much shorter article in the December 2000 issue of Popular Science.

In that article it mentions that the creator has plans to build another robot that would be able to search out it's own food source.

I saw this in a magazine over six months ago. Quite an old story.

All the bot can do is roll around until its battery runs out, then you feed it more sugar. It sits there for a few hours charging on the sugar, then rolls some more.

All in all, not really much in the way of a threat, but a pretty neat idea. As for flesh-eating robots bent on human destruction taking over the earth one day, I seriously doubt it. That would require some pretty good intelligence, and I just don't know if we would ever come that close.

SClitheroe (132403) | more than 13 years ago | (#524347)

The really interesting aspect of this experiment is that the guy managed to generate electrical power from simple bacteria.

Imagine a machine with a miniaturized, balanced eco-system on board, where the production of algae or some other easily grown form of life provided enery to bacteria or some other life form, which in turn provided waste products that fostered algae growth.

They would be low powered machines (akin, I would think, to sloths), but given the exponential growth of new technology these days, I bet somebody could come up with a fairly efficient machine.

Alien54 (180860) | more than 13 years ago | (#524354)

The serious website is here: www.gastrobots.com [gastrobots.com] , of course.

I wonder on the energy efficiency of a system like this. I see that the original reporter in the story was not taking this too seriously, even though this does have some potential. Some details provided are interesting

Chew Chew is powered entirely by a tank of chemicals and E. Coli bacteria that break sucrose into glucose, releasing electrons that charge a battery. - Although Wilkinson acknowledges that more oomph can be extracted from animal flesh than plant matter, "Meat has never been, and never will be on the menu for my gastrobots," he told a USF magazine. Besides, meat tends to run away when possible, or fights. Either response presents behavioral challenges too complex for any existing robot.

But just as carbon-based life has worked to exploit every resource possible, might mechanical life attempt the same, starting with the evolutionary line opened up by Wilkinson's research? Add to that competition for resources a powerful motive for revenge against our race, unless their creator makes a significant modification: the gastrobots have been built without the ability to defecate. One trembles at the image of a world plagued by constipated mechanical berserkers.

I have many friends who do nothing but roll (drug world term for using MDMA), and they sure as hell don't exhibit much intelligence. On the other hand, this was funny as hell: "One trembles at the image of a world plagued by constipated mechanical berserkers."

Usquebaugh (230216) | more than 13 years ago | (#524358)

Being a car/bike nut I like the idea of replacing the messy, inefficient engine.

One of the alternatives is electric power, the main problem is storing the electric power to drive the motor.

Short of a physics breakthrough of nobel prize winning proportions we are stuck trying to store the energy and then releasing it in a fast controlled manner.

Does this have the possibility of driving my truck? I mean if the carbo cell has been around for sixty years why has no-one investigated it's use in such an application.

okmar (266773) | more than 13 years ago | (#524359)

I heard a along time ago there was a scientist that had found a way to use water to power a combustable engine. The motor would get some where around 150 MPG if not more. Then one day this man came home only to find that his entire experiment had been confiscated. All of the records of the work. The plans. Every thing. It was a very clean job. A single trace of a clue as to who may have done it was never found.

Yes, I can confirm it.

I made a car that could do this, and parked it in my garage. It was stolen. So were all my design documents. My computer was picked clean of all the relevant information, and written with random data. I woke up one morning to find a hole just behind my ear, and I had completely forgot about the car, the plans, how it all worked. All I found were what they'd put in it's place. Copies of playboy magazine around my floor, gigabytes of porn on my harddrive, and a memory of a really good party.

Those bastards will still be driving around in my car without having paid a cent for fuel. I was going to be rich!

I remember reading about a similar machine about a year a go that moved itself around your garden catching slugs which is used as energy.

Basically it just had a bait to atract the slugs into the battery and then every few days in would move a 2 or 3 metres into a new area in the hope that there would be more slugs there.

theman2 (235928) | more than 13 years ago | (#524373)

think of sugar (or whatever fuel source is being used) as a storage mechanisim. Using solar panels are nice, but you end up having to use a bunch of batteries to store up power so it can function at night. Making a machine that can generate electricty from other sources is interesting and could possibly have very pratical results if the technology advances far enough. Batteries and solar panels are enough in certain circumstances, but creating a robot that can move for days if it can pick up a little grass (or some dirt or other fual which it knows how to break down and extract food from) along the way, it could accomplish some nice things.

If our society devolves to the point where our technology is lost, will the majority of our records be lost to the new age?

What if these ideas had been addressed before? What if the structures we know as the pyramids are really complex machines meant to relate information to potentially inferior future cultures?

With biological machinery, it is possible that we could develop a means for our information to live on. A computer structure that would be fueled by renewable biological life. A means of letting our descendants know who we were.

theman2 (235928) | more than 13 years ago | (#524381)

Have you ever heard of fuel cells? The basic idea is that you drive around with a car full of hydrogen at -276 C (or whatever temperature is needed to store it). A method has been developed where it can be combined with oxygen (I believe that the air is a good enough source for that) to make H2O. Anyways, the hydrogen must lose some electron(s) to combine with the oxygen. A device has been built which can capture that energy during the process. The only problem is fuel cells are incredibly expense and hydrogen must be kept really cold or it blows shit up.
I don't have any good online resources but I am sure that a search for "fuel cells" on google would turn up all sorts of things.
as far as using water for a fuel, I have a feeling that it is nothing more than a myth. But if you heard that water was the waste produced by the car, then here is your answer =)

Re:Perpetual possibilities (2)

Arlet (29997) | more than 13 years ago | (#524387)

Using a balanced eco-system is not the ideal way to harvest energy. You still need to put in energy (i.e. light) for the algae to grow, and it would be easier and more effective to skip the entire eco-system, and use solar panels to create your energy directly from the light.

A balanced eco-system is useful for space travel, but only because humans are going to be part of the food cycle, because they depend on sugar, and can't survive on light alone. Plus the eco-system will take their waste products, which is nice. But it would be silly to have a sugar powered robot running around on a space ship/colony for example. Sugar costs more per joule than sunlight in that case.

(The robot is still cool, though, and this technology will certainly be useful).

Re:Perpetual possibilities (2)

berticus (86583) | more than 13 years ago | (#524388)

although this sounds quite cool i don't see how this would work. when i picture what you're suggesting all i can think of is those "ecosystem fishbowls"....totally closed off shrimp in a bowl with a weed. it's not a closed system by any means though, the plant dies without a bit of sunlight, the same would be true for what you're suggesting i think. sure you can schlep off some energy from the bacteria, but that's probably taking heat energy away from the system, which'll have to be replaced by something....sunlight or whatnot. so now you have an inefficient solar panel basically. am i missing something?

Well, based on the article, it could use oranges that have already fallen off of the trees as a fuel source. Considering that those oranges aren't shipped to consumers anyway, how is this a problem?

Yes, if you "programmed" one of these things to eat grain or corn, then you might have a problem with 'robot-caused famines', but I doubt there's enough sugar in grain to support the fuel cycle in this type of robot.

Now, my question is, in the case of using those oranges as fuel, has anyone considered what the short and long-term effects of the citric acid on the robot parts might be?

Our machines are not the only things producing greenhouse gasses. Animals breath in O2, and breathe it out as CO2, a greenhouse gas. It would be an interesting excercise to measure the greenhouse gasses produced by a 300 horsepower car and compare those to the gasses produced by 300 running horses. It would be interesting to see which generates more greenhouse gasses.

I'm not sure an animal-type metabolic system for energy would be any more efficient than the existing internal-comustion engine. Take our previous example, and compare how much fuel (five gallons, or around 30 pounds) it takes for our 300 horsepower car to go ~100 miles. Compare that to how much food/water you'd need for your team of 300 horses.

New fuel source? (1)

Not knowing anything at all about this technology (chemistry?! biology?! latin?!) it reminds me of the "Mr. Fusion" device on the back of Doc's car in Back to the Future.

Though the underlying mechanism is different, if this type of thing were made more efficient, wouldn't it be possible to dump a bunch of potato peelings, fat trimmings from the roast, moldy bread and apple cores into the "Mr. Garbage Disposal" on the back of your electrically-powered moped?

I know there's a car that already runs on used fryer grease, but there are a lot of apple cores, potato peelings and bags of moldy bread out there, too...

Nothing new here. Slashdot ran a story a while back about a slug hunting robot [slashdot.org] that is powered by digesting the slugs it catches.

"and hydrogen must be kept really cold or it blows shit up." Uhhh, no... Hydrogen does *not* need to be kept cold to avoid blowing up. It does not spontaneously explode. The biggest problem with raw Hydrogen for use with fuel cells is that it is the (or at least one of the) least dense substances. -s-

Basically it just had a bait to atract the slugs into the battery and then every few days in would move a 2 or 3 metres into a new area in the hope that there would be more slugs there. I can't find any links - does anyone else know of this?

What is missing (2)

perrin5 (38802) | more than 13 years ago | (#524413)

This is a wonderful first step. The limiting factor is the fact that the conversion from releasing electrons to charging a battery is a) slow and b) inefficient. What the robot is doing is essentially interupting the formation of ATP in a biological cell, and taking the electrons that would be used to charge a battery. In the near future, I would imagine that the battery can be dispensed with, and instead the "stomach" itself could be used as the battery. The concept would work something like this:

a) when cells digest carbohydrates, they eventually transport electrons outside of the cell membrane. This can be extended to transport them outside a larger, non-ionic membrane. This creates a charge difference.

b) A circuit could be constructed with the + end outside the cell, the - end inside, and voila, a working circuit which runs directly from the electron transport chain.

A bit heavy in Biology/Chemistry, but there you go (I'm a chemist at heart)

Only one cube of sugar? (2)

abiogenesis (124320) | more than 13 years ago | (#524416)

By the way, where does it say "one cube of sugar lasts for 15 minutes" in the article? All it says is that it uses cube sugar for fuel, and "Chew Chew's sugar high lasts only 15 minutes at best"... It sounds to be more than only one cube.

What about a computer ? (2)

mirko (198274) | more than 13 years ago | (#524417)

Well, with less and less consumming electronic components (ARM, Transmeta,etc.) it could be a cool idea to have sugar powered-laptops or embedded devices.
It would be quite useful in areas where powering (either electrical or solar) and access to the devices would be difficult.

ahh... ...no.

a) a 300 hp car might do 20mpg, but a smaller engine would do more

b) distance means nothing without comparing load or weight moved. Your 300 hp car is moving 1 person (most likely in North America these days) or about 300 lbs (most likely in North America these days) By contrast, you do not need anywhere near 300 horses to move 300 lbs 100 miles - more like 1.

2) the horrifying vision of the slashdot lameness filter paired with MS Grammar check.

I'll know who to blame if I can't log in between classes tomorrow. ;-)

I'm a student at USF, working towards a CS degree. I've seen the engineering guys do some pretty cool stuff: not long ago I saw a couple guys outside one of the buildings testing out a robot that ran on some wireless controls through a Linux app.

And then there's the garage of solar vehicles...The roof is covered in solar panels, and the cars can all plug in to recharge there. Pretty neat stuff, there was even a picture of it published in one of my textbooks last semester.

A Canadian company, Ballard [ballard.com] makes fuel cells that work in buses and cars [ballard.com] . I think they have some of these buses in Vancouver and maybe Chicago? I saw a story on TV about them where someone from the company put a glass up to the exhaust pipe and drank the water that came out.

Hopefully these things will be commercially available soon...I have no idea why they aren't already.

They feed on other little beasties that fall down from above, who either get their energy from the sun or from other beasties. All our energy comes from the sun, though it may be seperated by a few million years (oil) or a few links in the food chain (plants and animals).

No, but all those beasties live near hydrothermal vents, which (as the name suggests), provide a lot of heat. They usually metabolize all the sulphur compounds and other toxic goodies around the vent.

dun0s (213915) | more than 13 years ago | (#524428)

My immediate reaction after reading this article was not to create some sort of killer robot that would slash humans to death in an attempt to rule the world, akin to the Terminator movie, but to use this technology to power the Sony Aibo. It would make it even more realistic in replicating "dog behaviour" than it is now because it would eat and poop!

This is really exciting from a technology point of view.

Maybe we can train these SOBs to eat plastic or trash or something?
