DARPA's Nightmare shop creates a fast kitty

Sounds like something out of the TERMINATOR...or maybe his pet cat. Either way, I'm not interested in running into one anytime soon.

DARPA's Cheetah becomes fastest legged robot. By Bonnie Cha

DARPA is quickly becoming the supplier of our nightmares.

As if the monstrous AlphaDog wasn't intimidating enough, it now has a feline friend, the "Cheetah", that will certainly have you running for the hills. Chances are you won't be able to outrun it, though.

Created by Boston Dynamics, Cheetah is allegedly now the fastest legged robot on the planet. DARPA released a video today showing the bot running at various speeds on a laboratory treadmill, ultimately hitting its maximum speed of 18 mph. This breaks the previous land-speed record of 13.1 mph set back in 1989.

Engineers designed the Cheetah bot by patterning its movements after real fast-running animals, such as its namesake. By flexing and unflexing its spine, the four-legged droid is able to lengthen its stride and increase its running speed.

Back in February 2011 when the robot was first commissioned, Boston Dynamics President Marc Raibert said he saw no reason why the robot couldn't go as fast a real cheetah (up to 70 mph), but he admitted that this would take some time to achieve.

The Cheetah is part of DARPA's Maximum Mobility and Manipulation (M3) program, which seeks to advance and improve robotic capabilities. Though the agency didn't provide any specific examples, a robot, such as Cheetah, could help in various military applications.

DARPA plans to test a free-running a prototype later this year

Darpa’s Super Sniper Scopes in Shooters’ Hands by 2011


Can't emphasise enough how this kind of weaponry helps the troops...Large weapon systems are great, but giving the Soldiers the ability to take out the bad guys, at distance, and in a manner that strikes fear in them, is what it is all about....small money spent for great return.....Go get'em guys.

I saw a Army Sniper team come off a plane one day at Kandahar at the flight line...they were carrying the long cases that hold their equipment....obviously, it wasn't a guitar they had in their cases.... I saw the equipment when the soldier opened the case to put something away....

I asked the soldier if he could do me a favor....He said, " Sure, what do you need?"

I said, " Makes every shot count."

Replied, " No worries.....we will."

Darpa’s Super Sniper Scopes in Shooters’ Hands by 2011

Earlier this month, a British Army sniper Corporal Craig Harrison broke the world’s record for superaccurate shooting, taking out a pair of Taliban machine gunners from a mile-and-a-half away. It was a one-in-a-million feat — one performed under “perfect” conditions, Harrison says: “no wind, mild weather, clear visibility.”

Darpa, the Pentagon’s way-out research arm, is hoping to use lasers and advanced optical systems to make other snipers Harrison-accurate, even when the winds are howling. The agency is looking for 15 ultraprecise sniper scopes to put in shooters’ hands by next year.

The “One Shot” program originally aimed to give snipers the power to hit a target from 2000 meters away in winds as high as 40 miles per hour. In the first phases of the 3-year-old program, shooters used prototype rifles dressed with lasers and fancy computer hardware to do damage from 1,100 meters away in 18-mile-an-hour winds. The scope-mounted lasers can “see” wind turbulence in the path of the bullet and feed the data to computers, enabling real-time calculation of — and compensation for — the wind-blown trajectory.

The program is just one of several high-tech hardware upgrades the U.S. military is pursuing for its snipers. Plans are also in place to make bullets that can change course in mid-air and a stealth sniper scope that would make shooters all but invisible.


With initial demonstrations complete, the next step for One Shot is to make 15 “field-testable prototype, observation, measurement, and ballistic calculation system[s], which enable [s]nipers to hit targets with the first round, under crosswind conditions, up to the maximum effective range,” Darpa says in its program announcement. Total cost: $7 million.

Darpa stresses that ”no alignment verification of the laser/crosswind optics to the spotting scope or calibration in-field should be required,” indicating that those early demos probably required a lot of tender loving care from the engineers who designed the systems. Lockheed Martin received $2 million to participate in the early phases of the program, and will presumably compete for the opportunity to make the rifles battle-ready.

What the agency really wants is a battle-ready system that doesn’t require tricky in-field optical alignment and fiddling with lasers. Night and day accuracy also means that the laser, which is used to help calculate and subtract wind turbulence between the predator and his prey, can’t be infrared. Enemies with night-vision goggles would see that from a mile away.

The program is slightly behind schedule. The original goal was to have production-ready scopes by fall of 2009. With luck, Darpa will have its new supersniper rifles by the fall of 2011.
