The Incredibly Shrinking UGV

, , , ,

In the early days of the Afghanistan and Iraqi wars, US forces had no effective countermeasures against Improvised Explosive Devices (IEDs), the single biggest cause of combat deaths. To fight the IED threat, our armed forces turned to Unmanned Ground Vehicles (UGV).

It’s hard to remember now, but UGVs barely existed 10 years ago. The Defense community abandoned the traditionally leisurely pace of decades-long weapons development and quickly flooded combat theaters with thousands of UGVs. In 2011, the world’s governments are projected to spend $702 million a year on UGVs.  Below is a chart comparing a few UGVs. Read more

Will Future Battlefield Computers be Futuristic?

, , , , ,

futureRecently, some clients asked AMREL to build an Operator Control Unit (OCU) for their Unmanned Ground Vehicle.  No surprise there; we dominate that particular application.  What was noteworthy was the specific form factor that they requested.  They wanted it to be a wearable computer, worn on the wrist.

We ran a simple experiment with the clients.  We strapped a small computer to their wrist and had them run some typical UGV commands.  Soon, they discovered that their arms grew tired supporting the computer.  The clients agreed to have their OCU installed in the traditional, if less exotic, form factor of a handheld.

Notice that the wrist-mounted form factor wasn’t discarded for technological reasons. AMREL has become quite adept at developing small, powerful, ATOM-based computer platforms, which would be perfect for wearable solutions. Rather, this innovative approach was discarded, because the wrist form factor proved impractical for this particular use. Read more

Libyan system integration video

, , ,

An IEEE Spectrum article features an Al Jazeera video (see below) about Libyan rebels making their own weapons.  The rebels transform a child’s toy into a weaponized UGV, prompting IEEE to conclude that “Anyone can (on principle, at least) build a robot, and given the need or the motivation, anyone can put a gun on one…”

Don’t believe the bunny: Power & Unmanned Systems

, ,

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
