Upcoming Military Robot Could Feed on Dead Bodies

Tuesday , July 14, 2009

It could be a combination of 19th-century mechanics, 21st-century technology — and a 20th-century horror movie.

A Maryland company under contract to the Pentagon is working on a steam-powered robot that would fuel itself by gobbling up whatever organic material it can find — grass, wood, old furniture, even dead bodies.

Robotic Technology Inc.’s Energetically Autonomous Tactical Robot — that’s right, “EATR” — “can find, ingest, and extract energy from biomass in the environment (and other organically-based energy sources), as well as use conventional and alternative fuels (such as gasoline, heavy fuel, kerosene, diesel, propane, coal, cooking oil, and solar) when suitable,” reads the company’s Web site.

That “biomass” and “other organically-based energy sources” wouldn’t necessarily be limited to plant material — animal and human corpses contain plenty of energy, and they’d be plentiful in a war zone.

EATR will be powered by the Waste Heat Engine developed by Cyclone Power Technology of Pompano Beach, Fla., which uses an “external combustion chamber” burning up fuel to heat up water in a closed loop, generating electricity.

The advantages to the military are that the robot would be extremely flexible in fuel sources and could roam on its own for months, even years, without having to be refueled or serviced.

Upon the EATR platform, the Pentagon could build all sorts of things — a transport, an ambulance, a communications center, even a mobile gunship.

In press materials, Robotic Technology presents EATR as an essentially benign artificial creature that fills its belly through “foraging,” despite the obvious military purpose.

Cool Stuff: Slinging.org

Filed under: Cool Stuff,Weapons — Tags: , , , , — Matt @ 9:14 PM

   This is a fun one, and thanks to Doug for sending me this.  I guess the one thing that is cool about slings, is that you could potentially use a sling as a less than lethal option for crowd control.  Thats all depending on the type of projectile you use. (please note the Israeli using the sling below).  Or if you are bored at some outpost and want something to do on your downtime, build a sling out of paracord and see if you can hit a tin can with it.  It’s cheap fun, but it is also cool to get a feel for how this weapon could have been used back when it was a weapon of war.  With the right projectile and some skill, a sling can certainly be deadly. –Matt

An Israeli soldier uses a sling shot to stone demonstrators and workers dismantling the area in front of the Fatima Gate on the Israeli-Lebanese border, at Kfarkila, southern Lebanon, Tuesday Oct. 10, 2000. The area was liberated after the Israeli’s troops withdrew from southern Lebanon in May.

Welcome to Slinging.org!

When I first became interested in this fascinating weapon, I could find little information on the web or in published material. I hope this website can be the definitive source for slinging related information and news. Of course, it needs a community of slingers to experiment and pass on their knowledge. With your help, I hope we can rekindle the interest in this truly simple, effective, and historically significant weapon.

Sling Ranges

The range of the sling has always been a point of contention among enthusiasts and scholars. Present literature generally underestimates the sling’s range. Consider this snippet of text from Thom Richardson’s “The Ballistics of The Sling”, which provides an overview of some of these statistics:

“The more conservative estimates are around the 200 m mark (Ferrill 1985: 25), Connolly suggests 350 m (1981: 49), Korfmann estimates 400 m (1973: 37) while Demmin and Hogg go to 500 m (1893: 876; 1968: 30). The few accurately recorded observations are rather different. Reid records 55 m with a 227 g stone, and 91 m with 85 and 113 g balls (1976: 21). Burgess threw stones with his reconstructed Lahun sling between 50 and 100 yds, but admits to being unskilled at the art (1958: 230). Korfmann observed Turkish shepherds sling ordinary pebbles, ‘in 5 out of 11 trials the pebbles reached 200 m, and the three best casts were between 230 and 240 m (1973), while Dohrenwend has himself thrown beach pebbles over 200 yds (1994: 86).”

Since many of these statistics are formulated from authors’ experiences, the ranges that are creeping into literature, and becoming the standard, might not be representative of the true potential of the sling. The sling is a demanding weapon; range varies considerably from amateur to expert. Below is a table documenting the varied ranges of some members on slinging.org’s forum. It’s also important to consider the projectiles used in the test. A stone or softball will not perform as well as a biconical lead projectile, like those often used in antiquity.

For comparison, the current World Flight record for a “historically accurate” English longbow and horn/sinew composite bow is 306m and 566m respectively. It should be noted, however, that these ranges were achieved using light-weight flight arrows designed for range, and not for combat.

Technology: The Cantenna–A Field Expedient WiFi Antenna

     On most contracts out there, you will have access to some kind of WiFi or internet connection.  If you have access to some WiFi, yet you are a little far from that WiFi hub to get a full signal, you just might have to make a field expedient antenna to make a connection.  This little DIY site is awesome, and explains the parts and process for building a cheap WiFi Antenna that you could throw away after your contract is over.(save the nuts and bolts, the N type female chassis-mount connector, and wire if you want) You can also buy an amplifier to increase the strength of the signal. These parts are small and light for just a basic Cantenna, and I like that. To read more about WiFi antennas, check this out.

     Also, if you are going to use WiFi over there, make sure to use password protected WiFi hubs, and only use the unsecured WiFi hubs at your own risk.  Also, make sure it is authorized in your AO to set something like this up.  Some camps would not be down with this stuff and others probably don’t care. As to the FCC’s thoughts on WiFi antennas, here you go. –Matt

Tin Can Waveguide Antenna

How To Build A Tin Can Waveguide WiFi Antenna

Got no dough for a commercial WiFi antenna? Looking for an inexpensive way to increase the range of your wireless network? A tin can waveguide antenna, or Cantenna, may be just the ticket. This design can be built for under $5 U.S. and reuses a food, juice, or other tin can.

I am not an electrical engineer, nor do I have access to any fancy test equipment. I’ve built some antennas that worked for me and thought I would share what I learned. I have no idea if this is safe for your radio or wireless network equipment. The risk to you and your equipment is yours.

Building your Cantenna is easy, just follow these steps.

   1. Collect the parts

   2. Drill or punch holes in your can to mount the probe

   3. Assemble the probe and mount in can

Technology: The Phoenix Junior Intruder Beacon

Filed under: Cool Stuff,Technology — Tags: , , , , — Matt @ 8:18 PM

   I could see a use for something like this.  If you’re on night shift and you have a large area to keep track of, setting up a couple of these could help you to increase your coverage of an area.  The best part, is the guy that trips it would not know he tripped it unless they had night vision optics. Cool stuff. –Matt

Phoenix Junior Intruder Beacon

A trip switch activated, covert intrusion detection signaling beacon

Phoenix Jr. Intruder Beacon System (NSN: 5855-01-539-0639) is a trip wire activated infrared beacon used in conjunction with night vision equipment to detect and signal night movement along trails, roads and entry points.

The system consists of the trip wire unit, one reusable 50 ft. line bobbin, an Allen wrench used for winding the bobbins, two magnetic mounts and the Phoenix Jr. Intruder Beacon. The Phoenix Jr. Intruder Beacon flashes at a rate four times faster than the Phoenix Jr., thus differentiating it from the standard combat identification signal. Alternatively the trip wire unit may also be used with any Phoenix or Pegasus flashing beacon, and is available for purchase separately without the Phoenix Jr. Intruder beacon.

Cool Stuff: The Bionic Shirt, by Ranger Up

Filed under: Cool Stuff,War Art — Tags: , , , , , — Matt @ 4:56 PM

   This is a great shirt, and for you war machines out there, this one is for you. I am also amazed at the development of prosthesis these days.  The rate things are going, more and more amputees will be able to join back up in their units because of bionics and these advances.  Even contractors will be able to continue to work with these types advances, and as this war continues, I think we will see more and more of this type of thing.  I guess my point is, if soldiering or contracting is in your blood, then an amputation should not stop you from continuing.  Especially when bionics actually start to enhance capability.

   I can even attest to some body modification/enhancement.  I had laser surgery for my eyes back in 2002, and it was the best thing ever for this kind of work and for smokejumping.  My vision sucked before hand and I had to depend upon eye glasses.  That wasn’t good for parachuting, and I wanted to kick my dependence on those things. I got the surgery and now I have 20/15 vision!  The outcome was way better than I ever expected, and for contracting, your eyes are extremely important for the observation part of your OODA.  

   In my leg, I have a titanium alloy rod holding together my femur.  This does not really enhance my capabilities, but I guarantee that my femur won’t break there anymore.  ha ha Now that is nothing like actually losing a leg or arm, but it does give me a profound respect for those that have prothesis and have to live with that metal and plastic in them and on them, just in order to walk or grip something.  It is my hope that all of you guys and gals out there that are amputees or wheel chair bound, will one day not only live a normal life based on the advances of bionics and prosthesis, but be enhanced by it.  It will happen, just like it happened for my vision. –Matt
