I don’t know about you, but I am sick of certain clichés about unmanned systems and combat.  It’s just my opinion, but some commonly repeated statements confuse, rather than clarify.  Here are a couple of my “favorites.”

“The use of unmanned systems in combat will destroy the warrior ethos.”

I’m sure you’ve heard this.  “They’re cowards, these so-called ‘soldiers’ who strike from afar. A real man confronts his enemy face-to-face. These new weapons should be banned.”

Of course, this quote is from a French nobleman talking the English archers and their long bows.  The whole argument about the unmanliness of “death from afar” probably started the first time someone threw a rock. This line of reasoning ignores the fact that war isn’t about building soldierly virtues; it’s about winning (or to paraphrase Patton, “Making the other guy die for his country”). Read more

The Department of Defense’s (DoD) ambitious smartphone program may or may not reach its goal of providing advanced mobile communication devices to the warfighter, but it certainly has already scored one noteworthy achievement: creating stories for journalists.  At last count, Google News has 300+ entries for “military smartphone.” Most of these stories report that the single biggest obstacle to smartphones deployment is security.

TrobotMoneyhere’s nothing quite like the prospect of a half of a billion dollars to get the blood pumping, the brain scheming, and the pundits pontificating. The President’s ambitious Advanced Manufacturing Partnership (AMP), which includes $70 million for robots, may not revive the American manufacturing sector, but it certainly has provided fodder for the technology media.

In describing computer displays, what do the terms “transmissive,” “reflective,” and “transflective” mean?article page main ehow images a07 r9 0e adjust brightness desktop computers laptops 800x800

Transmissive is the most commonly used means of illuminating a computer display.  The display is lit up from the back. While this method is fine for indoor use, strong sunlight may overwhelm it, making the computer screen difficult to read.

Reflective method does very well in the bright outdoors.  The computer is illuminated by the reflected light of the computer’s surroundings. The brighter the sun, the brighter the display.  However, it does not do well in dim settings, i.e. indoors.

Transflective combines the transmissive and reflective methods of illumination.  This gives the viewer the best of both worlds, enabling the display to be optimized for the greatest variety of environments.

Even though transflective appears to be the best method, it may not be the best for you. You need to consider your applications specific needs, including energy usage, heat generation, and issues such as compatibility with night vision goggles.  Display brightness may also be affected by chemical treatment of the surface (anti-glare coating), viewing angle, contrast controls, and a host of other factors.  For more information, see Are nits the only important rating for hi-bright display?

Despite the ad with the drumming bunny, batteries in unmanned systems do not last forever. In fact the performing rabbit robot’s power lasts only three to four minutes.Robot power

Battlefield robots do better (a typical UGV batteries may last about 2 hours), but power is a huge challenge. This seems counter-intuitive, since one of the main advantages of unmanned systems is that, by definition, they don’t have to lug around people. However, mobility is only one source of power consumption. Communications and cooling systems may actually be more of a drain than simple transport. Read more

wordsEvery once in a while, someone asks me to translate military jargon, or more often summarize a lengthy statement into an “executive summary.”   Here are a couple of examples of my attempts to convert a dense forest of words into a simple “take home message.”

The direction for unmanned systems and all of the Defense ugv multiple or single assets  community is clear; we must do more with less and do it faster. We need to create the best possible systems for tomorrow’s needs as soon as possible. One niggling little problem: what does tomorrow look like?

For example, do we develop unmanned systems with multiple assets or a single asset? Which payload configuration will be desirable for the future warfighter?

The obvious answer would seem to be, the more the better. Take the case of Sensitive Site Exploitation (SSE). Soldiers would love to have a robot that can enter a potentially dangerous house and clear it with non-lethal stun grenades. Of course, any armed application should be matched with optical surveillance capabilities as well. Olfactory sensors would be valuable in detecting explosives. When you add to the wish list an IED jammer and maybe the ability to detect ABC weapons, a multiple-asset unmanned system seems virtually certain. Read more

One of the big changes for military vendors in recent years has been the greatercots-good-bad-ugly  emphasis placed on acquisition of Commercial Off The Shelf (COTS) products by the Department of Defense (DoD).  In the past, COTS constituted a few percent of all items purchased by the DoD.   While the overall amount is still low, some weapon systems are composed by as much as 50% of COTS.  What are the good, the bad and the ugly about COTS?

Good:

1)    Cost:  One of the main drivers for the acquisition of COTS has been the price. By definition, COTS products have no development cost, so, in theory, the DoD gets a cheaper item. Despite its behemoth budget, Defense still accounts for a minuscule part of the electronics market.  So, by buying from the much larger commercial sector, DoD also benefits from economy of scale.

At a gathering of unmanned systems professionals, I heard a lot ofrobot attack  griping about product development.  Trying to deliver a system that the government wants was impossible, because of the time lag.  Who knows what the Department of Defense would want or need 2 or 5 years from now? All participants in the meeting agreed that it was the governments’ fault.  The Feds simply weren’t telling us what they wanted.  Well, it’s not for the lack of trying.  It seems every week there’s a new roadmap, report, vision, or long-term plan.  I recently reviewed my personal collection of downloaded documents and came up with: Read more

Those who work in an engineering/hi-tech culture know the  Biometrics Iris Symbol BIOMETRICS importance of “specs.” Go to any biometric solution provider’ workplace, and you will see highly trained professionals closely examining the latest RFP, eagerly analyzing the specifications, as well as the Scope of Work.

Focusing on specifications alone can lead to not only tunnel vision, but also to a kind of passivity.  We shouldn’t sit around waiting for the RFP to tell us what to do. We should go out into the field at every opportunity and seek input from end-users.  That’s why AMREL is a fixture at events such as the Tactical Network Topology (TNT) and Biometrics Field Experiments (BFEX).
