The Army's $10M Spy Bat Still Too Big

Lucas123 writes "The University of Michigan's Center for Objective Microelectronics and Biomimetic Advanced Technology (COM-BAT) is working on building a robot bat that would perform long-range reconnaissance for the U.S. Army, but U.Mich is currently struggling with miniaturizing components in order to make the bat small enough to be stealthy. 'The focus is to shrink down many electronics that while currently available would only be good if the US Army wanted, say, a 12-foot spy-bat.' Some components need to be 1,000 times smaller than they currently are. The Army's $10 million grant proposal calls for the bat to be six inches in length, weigh four ounces and use just one watt of power. The bat is supposed to be powered by a lithium-ion battery, charged by solar and wind energy, as well as simple vibrations."

Vampire?

[cayenne8]

Why not make a requirment to be a vampire bat?

It could feed on blood...and thus hurt the enemy, and generate power for long missions. It would be cool too, in that it would only come out at night, and could only be killed with a wooden stake.

We were somewhere around Barstow on the edge of the desert when the drugs began to take hold. I remember saying something like, "I feel a bit lightheaded; maybe you should drive . . ." And suddenly there was a terrible roar all around us and the sky was full of what looked like huge bats, all swooping and screeching and diving around the car, which was going about 100 miles an hour with the top down to Las Vegas. And a voice was screaming: "Holy Jesus! What are these goddamn animals?"

Then it was quiet again. My attorney had taken his shirt off and was pouring beer on his chest, to facilitate the tanning process. "What the hell are you yelling about," he muttered, staring up at the sun with his eyes closed and covered with wraparound Spanish sunglasses. "Never mind," I said. "It's your turn to drive." I hit the brakes and aimed the Great Red Shark toward the shoulder of the highway. No point mentioning those bats, I thought. The poor bastard will see them soon enough.

Sounds like a comic book prop

[jollyreaper]

Quick, Robin! Hand me the bat-bat!

But seriously, why go with an ornithopter design? There's that excellent quote about AI's, "The question of whether a computer thinks like a person is as relevant as whether a submarine swims like a fish."

Would not a conventional ultralight drone with battery-operated propeller work more effectively than flappy wings?

But seriously, why go with an ornithopter design?

Stealth. It needs to act (at least somewhat) like a real bat or it will be detected. Real bats are ornithopters. Ergo, the spy craft must be an ornithopter.

COM-BAT?

Okay, this is taking military acronyms way too far..

Solar power?

I've always thought that bats are nocturnal.......

Pigeons next

[TheMeuge]

The idea of a bat-like creature is probably a concern because fixed wing designs will attract more attention.

Basically, they want something that'll look like a bird, fly like a bird, and would be able to engage in surveillance without anyone noticing. The next logical step would be to make a pigeon-like creature, that would be unnoticeable in an urban environment. A few thousand of those in a large city could make enforcing "free speech zones" much easier.

I find fault with your logic, because you're assuming that one's beliefs and principles override one's requirement to work in order to feed, clothe, and house themselves and their families.

Giant bat?

[Mongoose Disciple]

You know, a 12 foot robot bat might be a bit big for spy missions, but maybe it could be repurposed to scaring the hell out of and possibly murdering people.

It's a 12 foot robot bat, man! That'd scare the hell out of me if it came for me in the dark.

Re:Magic Charge

[Bobb9000]

Since the article says it's supposed to be long-range, my guess is that the mission profile would be to sit somewhere out of the way and charge during the day, then do its recon at night. All of those methods are very useful, because it means the drone could stay in an area and continue to operate without human intervention nearly indefinitely.

What this project needs RIGHT NOW

[kjoonlee]

There are several things that this project needs RIGHT NOW in order to be successful.

First, a whizkid plucked out from high school, who will be separated from his mommy for the first time ever.
Second, a crazy roommate who doesn't care about authority figures
Third, a mysterious man who lives in their closet
Fourth, an annoying dude who tries to suck up to his professor
Fifth, a charming young lady, interested in the whizkid, who just happens to be hyperactive
Sixth, an ambitious and immoral professor who's tricking the innocent to UNKNOWINGLY CONTRIBUTE to a MILITARY PROJECT
Seventh, said professor's inordinate hatred for popcorn -- oh wait...

So is the cure for cancer. And given the choice, I know where I'd want my taxes to be spent.

You present a false dichotomy.

I'm generally in favor of reduced defense spending, but research into new capabilities is something I think is worthwhile. I wholeheartedly agree that a cure for cancer would be better than this, but we don't have that choice available. Even if we did, it's likely that a few $M taken from a robotic bat project wouldn't even be close to enough.

We can spend money on both. Whether spending tax money on this is a good idea is mostly unrelated to whether spending tax money on medical research is a good idea. Obviously the two are connected through tax rates and thus the total government funding available, but as long as the projects are small relative to the total fund, they should each be evaluated against the alternative of reducing taxes (or increasing them, depending on your preferred viewpoint), rather than against each other.

We're all (well, mostly) smart people here, capable of evaluating complex choices. Let's at least look at the correct set of choices, rather than a rhetoric-filled politically motivated set of options that don't actually exist.

So you're saying it would be assassins, ninjas, and pirates vs Giant Robot Bat?
