Self-Guided Bullet Can Hit Targets a Mile Away
New submitter jpwilliams writes "Gizmag reports that researchers at Sandia National Laboratories have tested a 10-centimeter bullet that can be fired from a smooth-bore rifle to hit a laser-marked target one mile away. The bullet 'includes an optical sensor in the nose to detect a laser beam on a target. The sensor sends information to guidance and control electronics that use an algorithm in an eight-bit central processing unit to command electromagnetic actuators. These actuators steer tiny fins that guide the bullet to the target.' Interestingly, accuracy improves with targets that are further away, because 'the bullet's motions settle the longer it is in flight.'"
Sounds more like a dart than a bullet.
The real trick is training the sharks to fire the rifles.
A feeling of having made the same mistake before: Deja Foobar
Personally i don't believe it. A mile away? They probably couldn't hit an elephant at that dist
This Space Intentionally Left Blank
If everything went metric we wouldn't have these problems. The bullet is 10cm not 10in.
At last, our technology is starting to catch up to 1940s cartoons! I can't wait for my portable hole...

smooth-bore rifle
"Smooth-bore" and "rifle" are mutually-exclusive terms. Pick one.
Application? How about an overhead drone carrying a payload thats roughly the same weight as now, except instead of blowing things up it just shoots you in the face. You dont have to carry a huge amount of munitions when 95% of the bullets will hit the target.
From now on, whenever you see a new military technology you should think about how it works with drones. For example, it probably isnt a coincidence that our new magnetic launch systems on carriers will allow lighter, more fragile aircraft (read, composite drones) to be launched. The official line is it does less damage to tradition aircraft, which it does. But the guys calling the shots on this stuff make war for a living, and the writing is on the wall as far as the future goes. "Lighter. Cheaper. Disposable"
But it costs money (no idea how much) to train that sniper, and if they are injured you've lost their value. Whereas if the guy using this gun is injured the person next to them can pick it up and use it. Not an expert of course...
In the gaming universe this is known as an "aim bot", and is routinely derided as a hack for no-skill n00bs.
It should be popular.
Learning HOW to think is more important than learning WHAT to think.
World record is a mile and a half. http://www.nypost.com/p/news/international/sniper_kills_qaeda_from_mi_away_sTm0xFUmJNal3HgWlmEgRL
5 miles? That's pushing the limits of physics just a little too much. It would take a shitload of luck to get a hit from that far away. Farthest I've personally seen done is just over a mile (1800m).
And as others have pointed out, it takes time and money to train a sniper. It also takes a *lot* of luck at the upper ends of distance. You have to account for ballistic trajectory, air resistance (which changes with the temperature), wind (which can change directions remarkably easily), moving targets, etc.. Even at the speeds a bullet travels at, it still takes a discernable amount of time to reach the target at that distance. Having something you can fire and forget, and let your spotter guide it to its target with a laser pointer is a huge improvement, IMO. And besides, it's not going to cost a million bucks a pop once it's in production. Development may have cost that, but nothing in the device is all that expensive to actually make.
Actually, it states 2,475m = 2.475 km = 1.5 miles. I know, we Americans tend to assume everything is measured in miles, but the rest of the world tends to disagree.
It requires the high tech 'sniper' skill of "setting up a tripod, pointing the laser at the target, and then taking your hands off". Seriously, a sniper's skill lies not in putting the crosshairs on the target, but in putting the crosshairs off the target... such that wind, bullet drop due to gravity, etc.. etc.. ends up putting the bullet where the amateur would put the crosshairs - and miss. But wind, gravity, etc... don't effect the laser, so an amateur can place the crosshair by eye.
Of course the laser spot isn't the target for the bullet, who's trying to destroy a laser dot?!
Probably a cat.
No offence, but is there any good reason to use domain name shorteners when posting links in forums / blogs? Surely it's easier and quicker to just copy and paste the original url, which actually has the additional benefit of giving us a clue as to where it leads to? Or maybe you're interested in the click stats Goo.gl provides?
/. comments history that you're not an idiot so I did follow the link, which for anyone else interested, resolves to http://www.instructables.com/id/Laser-Ball/.
Having said that, I can see from your
