Tiny Aircraft Feeds Itself With Dead Flies
An anonymous reader writes "The research team from southwest England have built a robot which can move and transmit sensor data over a radio link powered solely by unrefined food including dead flies and apples.
The robot, known as Ecobot II, uses a Microbial Fuel Cell as its only power source. By "digesting" its own fuel, the aircraft could become autonomous and operate without the need for refueling, changing batteries or recharging from the mains. In the Microbial Fuel Cell microbes are used to extract electricity directly from food - in this case flies or apple." Several people noted this previous article on the same project.
This sounds just like Mr. Fusion! Definitely more effective if you pour the beer out of the can and then toss in the container.

At what point do they decide that they want human flesh instead of flies/rotten apples?
Or better yet, at what point do they decide that they want to eat our crops instead of flies/rotten apples?

Job? I don't have time to get a job! Who will sit around and bitch about being broke and unemployed then?

Now when some AI hacker can gives it enough brains to catch it's own flies, it'll be time to welcome our new robot-sparrow overlords...
This is both fascinating and frightening. Imagine the possibilities! Though the prospect of nanoparasites is somewhat frightening.

C. violation of airspace?
Couldn't a spybot just land on a powerline and get power from induction? Or how about eating something that doesn't move around as much as a fly, like grass or tree sap? Better yet, why stop to power up at all--just use direct solar energy either photovoltaicly or by embedding chloroplasts directly in the vehicle.
There's a dead tiny-fly-eating-aircraft in my soup!
Aircraft the size of bees that get the energy they need by feeding themselves a diet of dead flies could be buzzing around the battlefields and motorways of the future, thanks to research in southwest England.
The aircraft, up to 15cm long and equipped with sensors and cameras, could have a number of uses in civilian life and modern warfare, including reconnaissance missions, traffic monitoring or fire and rescue operations.
By "digesting" its own fuel, the aircraft could become autonomous and operate without the need for refuelling, changing batteries or recharging from the mains.
The research is being carried out by scientists from the University of Bath and the University of the West of England who are working on different aspects of the technologies involved.
The University of Bath researchers are studying the complex aerodynamics needed to fly very small unmanned aircraft. The smaller an aircraft is made, the slower is its speed and the more it is vulnerable to high winds. This means that existing micro air vehicles can only fly for short periods at low speed and are too large to carry out fine manoeuvres.
But the Department of Mechanical Engineering at the University of Bath is now carrying out five research projects over the next two years to find ways of overcoming these problems.
One approach they are working on is to get the micro air vehicles to flap their wings in a similar way to insects such as bees, flies or birds. By studying animals' motion, the researchers hope to match the efficiency of nature and keep smaller aeroplanes in the sky for long enough to carry out their tasks.
Professor Ismet Gursul from the University of Bath's Department of Mechanical Engineering says, "In general this kind of low speed aerodynamics is not as efficient as high-speed aerodynamics so you could never achieve the same efficiency as you would get for high speed civil transport aircraft.
"Insects and birds are as efficient as they could be, so we look at how they are doing this and try to imitate their flapping mechanisms"
Like insects and birds, it is just possible that such micro aircraft might one day even be able to feed themselves. Researchers at the University of the West of England are creating a new breed of autonomous robot that will carry out specific tasks and even "feed" themselves while working.
The research team have built a robot which can move and transmit sensor data over a radio link (over 30m inside the lab) powered solely by unrefined food including dead flies and apples.
The robot, known as Ecobot II, uses a Microbial Fuel Cell as its only power source. In the Microbial Fuel Cell microbes are used to extract electricity directly from food - in this case flies or apple.
Professor Chris Melhuish, Director of the Intelligent Autonomous Systems Laboratory at the University of the West of England, says, "We are interested in developing robots that are intelligent and autonomous which means they do the right thing at the right time and without human intervention. One of the big problems with autonomy is that of energy; they have to get their energy from somewhere.
"To do this they need to get energy from their environment which could include sunlight or water, but in our case it is organic matter".
The 1kg Ecobot doesn't move at any significant rate, about 30 metres per hour, but its ability to power itself by digesting its fuel is a major advance in the way such units have been designed so far.
Insect-sized aircraft could be possible in the future, says Professor Melhuish, "The biological fuel cell would have to be made into a soft system which might, in the future, be able to do some sort of movement at a small level, a small insect level."

Initiate spell check.
Could you imagine flying on it and getting close to no fuel? Suddenly the pilot tells everyone, "we are looking for large patches of flies in the air to maintain the flight course, but we have no fuel left." Then boom, you crash land in an apple farm only to have the plain eat them before you do, even though it is unable to fly?
Damn tricky plains.

+1 Insightful, -1 Troll. What can I say, I'm an Insightful Troll.
I can see it now, the robot spends all it's energy every day hunting flies to sustain itself and can't ever find time to surveil the battlefield.
surely a tiny aircraft could land on a high tension wire and 'fuel' itself off the magnetic field.
it's been a while since physics201 but the inductance from the magnetic fields already occuring everywhere would be a potential power source.
Watch as money gets worthless as tiny robots take over all niches on planet and eventually build a slave race of flies and fruit trees.

If the mission depends on the target being a sloppy housekeeper, then that's totally different. Maybe for version 2.0 they could program their spybot to sense when the fridge is being opened and dart in there to feed on mold growing on the bottom.
Ok, I've read the article 2x, and read the other posts, but i'm not seeing any aircraft. Seems the current stage of the technology is a 1kg Ecobot that achieves an astounding 30m/hr - is that fast enough for takeoff?
So if the food were say... a piece of fairy cake, would it show you your place in the universe?
It won't be long before we all need this.
"And when they grab you with those metal claws, you can't break free.. because they're made of metal, and robots are strong."
More correctly, possibly a future robot or robotic aircraft might one day feed itself with dead flies, according to the article.
An actual working model that's capable of flight looks to be well in the future. However, another(?) group in England is working on a someone similar design that'll eat garden slugs. That seems far more workable...

Please stop stalking me, bro.
So let me get this straight; you want me to board an airplane fueled by organic materials? Does this mean in the advent of engine trouble I will not be asked to volunteer (along with a Frenchman, Scot, and Mexican) to bail out in order to save the plane, but I will be fed to the plane instead?
I see interesting applications of this technology in future Itchy and Scratchy episodes.
"...its ability to power itself by digesting its fuel is a major advance..."
They don't explain how the 'back-end' of the digestion process works. Guess they'll need to create even smaller robots with pooper-scoopers.
Yes we should definately spend our time researching future power sources that consume "food" and oxygen then convert it into energy, waste and CO2. Yes that's definately the best idea. We don't have enough of that on this planet. Real robots should be like real men. They should eat meat and burp.
Making something that consumes waste, CO2, and sunlight then converts it into oxygen and energy is a stupid idea. Only idiots would take this approach. Solar cells are for tree huggers and commies.
So, I can see how an aircraft might get FLIES stuck to it, but Apples? Man, you're flying WAY too low!
I might know what I'm talkin' about, but then again, this is Slashdot...
It seems that for an electrical device it might be easier use to electromagnetic energy without the need to convert chemical energy from biomass. I remember someone at the university talking about having a small robot just land near a power line and recharge its batteries using induction. Or I imagine in an urban environment there might be other powerful sources of EM energy. But obviously in a remote location, flies and apples would work better.
Any engineers who know more about this?
can anyone tell me, when are the three laws of robotics NOT required?

The fact that we can turn food and other organic material in electricty is what excites me, more then the robot itself.
Could we use this to process our junk, or a good chunk of it in to electricty.
A compost pile that can power power your house, if only just as a small supplement would be cool.
It's interesting to note that Asimov's 3 Laws only cover robots not harming humans. In other words, robots eating flies, killing dogs, or harpoon whales are all fine according to Asimov. Maybe it should be changed from "humans" to "living thing"?

There was a very interesting discussion on the Diane Rehm show about West Nile virus and mosquitoes. One interesting topic of discussion was the issue of mosquitoes in the environment. One argument is that mosquitoes have no ecological benefit and that the world will be better off without them. Sure birds may eat the larvae, but most if not all birds' diets can consist of other insect larvae and other adult insects.
I say we should concentrate on robots that feed on mosquitoes and its larvae. Not only will it be good for robots, but we'll reduce the burden of the diseases that mosquitoes carry such as malaria and West Nile.

My guess is that the best practical way to do this is to have it land on already dead organic matter and "feed". Catching a fly in midair is tough. :)

Its amazing how some of the folks on here seem to be mental midgets.
First off "aircraft" is defined as "A machine or device, such as an airplane, helicopter, glider, or dirigible, that is capable of atmospheric flight.". In other words, a machine that can fly is an aircraft -- its not defined by size, but by flight ability.
If you made a model RC plane and it actually flew -- you made an aircraft.
Secondly,
Its very smart for researching to look into alternative fuels, especially clean burning and renewable ones like vegetation and animal life.
Open your mind - research of this little tiny thing, can spring board (over years of more research) to much much bigger things. You have to walk before you run.
As suggested about why not using power lines to refuel by induction....yeah that's fine for smaller towns with plenty of power to spare...but the larger metropolitian areas (like near me) have power sags and brownouts enough as it is with too much demand on the grid, sure lets have hundreds of thousands of little robotic insects suck out more power from the grid.

I've been reading autobiographies of astronauts and others involved in the US Space program recently. They all talk about the fuel cell developed and used during Gemini and later Apollo. I want to know why, 40 yrs. later, these things are not yet practical? Was there just not enough motivation to make one work in that 40 yrs or was it because until now, gas was relatively cheap and no one cared about the smelly smoke coming from cars?
I say force a greater percentage of cars to be hybrids as a start and get ready to roll out the fuel cells.

As long as there are dead flies hovering in the air at conviently spaced intervals.
I can see it now, the robot spends all it's energy every day hunting flies to sustain itself and can't ever find time to surveil the battlefield.
On the other hand, as a backpacker, I'd love to have a couple of these flying around me during black fly season. They don't have to fight, just fly around my head and catch flies. They can sit fat dumb and happy all night if they want, as long as they keep the flies off me during the day.
Think how this would help researchers in the field as well. They'd allow an archeologist to actually concentrate on his work instead of swat flies. Allow field work in the yukon without bio suits.

I few years ago I was reading the skymall catalogue on a cross-country flight when I came accross a similar product. Somebody had invented a little wheeled robot to get rid of slugs in your back yard. It somehow sniffed out the slugs, picked them up with a robotic arm, and dumped them in a canister on its back. It then fermented the slugs into alcohol, which it used to generate electricity to power itself. Sure this new tech doesn't rely on an alcohol intermediary to turn bio into electricity, but that also means you don't get to drink the excess slug rum.

How can you extract electrity from dead things if there isn't any?
Not only can it be done, many landfills are doing this already. Methane is a common by-product of landfills, and it is a unwanted greenhouse gas. They collect this in underground pipes, and then burn it. Commonly they burn it in a generator to generate some extra income
There are downsides though. The amount you get make doesn't really pay for the maintenance on the generators. If it wasn't for environmental concerns over methane they wouldn't do it at all. There just isn't that much to collect.
Much easier to use the garbage to power an incinerator, but incinerators are sensitive to the what you feed in. Landfills hold things you shouldn't toss like batteries without too many problems, while the tends to put the chemicals into the air. (modern landfills are lined so that the contamination doesn't escape - at least in theory)
It'll only be useful during the summer in England. A plane that can only fly 3 days a year isn't much of an invention

My strategy for using the spent grain is to bake a coarse whole-grain bread with it. I usually make a new batch at the same time as I'm re-racking an old batch, so I use the spent yeast from the first batch as well (although I usually need to add some bread yeast as well to get enough activity.)
Rye breads are particularly good this way since the caraway seeds offset some of the bitterness of the spent grain. I also like to substitute some of the partially fermented beer from the first racking for water in the bread recipe, which gives some additional flavor and nice sweetness from the unfermented malt.

If we kill all the mosquitos, it will make a significant dent in the wasp population too, since that's primarily what the stinging little bitches eat.
Killing all the wasps is a good thing. I don't care if the rainforest dies just because the date wasps are extinct. Kill all the wasps!
It will be more cool when the robots start eating people for energy.
By "digesting" its own fuel, the aircraft could become autonomous and operate without the need for refueling, changing batteries or recharging from the mains. In the Microbial Fuel Cell microbes are used to extract electricity directly from food - in this case flies or apple
Of all the food,why apples??? Because there are so many apples avaliable to be ingested by flying aircrafts.
You are absolutely correct that we need to consider every angle before doing something to nature. I mourn the loss of the Native American societies who lived not to domineer over nature but to be wise stewards within it.
My problem is with statements like "...consequenses would certainly be local....". How do we know that?
We know that because we already have machines that slaughter the bloodsuckers en masse. I mentioned them above. They mimic the breath of a mammal to lure mosquitos. They cut down the *local* mosquito population.
I have yet to hear of any catastrophic environmental consequences. I'm all for conservation/restoration, but the mosquito population where it's thick enough to be annoying could easily stand to be lessened and still be enough to feed birds/pollinate flowers/whatever. Realize that there can be MILLIONS of these little bastards in a single area. The out-of-control skeeter numbers are, I presume, due to some other human-caused problem. Like I said before, I think we've already wiped out any "environment" that could need protecting. In fact, I'd wager there are many of situations where actively controlling the mosquito population would be the *responsible* thing to do.
Nevertheless, as irritating as I find mosquitos, and as much as I would welcome a world without little winged vampires, the best course of action is for people to just grin and bear it--or wear some OFF. They're just mosquitos. But if/when they become a health hazard (if West Nile gets out of control, for example), I choose humans over bugs.
I hate crap like this. It's all about making money. I've seen this before and the formula goes something like this:

just a few comments that came a couple hours after reading mostly a comment on military largescale systems. only time will tell. well either time or a cadre of dod funded researchers and engineers. it's still quite smallscale however considering the US DOD especiallies new robotic /unmanned units.. all they need is fuel sustainability and you have a continously (except repairs etc..) mobile unit...
just add a a variety of choice ai systems.. whala. a new techno monster drone which could be programable for a number of tasks..
and yes they have programmed hunterseaker flying drones befor so I have heard.
its gets sicker when you consider their stealth systems.. including chameleon system..
but it seems that the microbial fuel cell is being geared towards small scale recon and sensor units.
the other though although I'm not a bibleprophecy person is could the future flying locusts be the black flying things that plauge the faithful.. or in modern times those that do not display their VISA?
