Smallest ever free-flying device

Tom James @ 17-08-2009

smallest-uavThe world’s smallest free-flying device has successfully flown. The DARPA-commissioned nano-air-vehicle flew TK without external support:

Aeronvironment has released a video that shows its “nano air vehicle” (NAV), which is the size of a small bird or large insect, hovering indoors without such crutches and under radio control. “It is capable of climbing and descending vertically, flying sideways left and right, as well as forward and backward, under remote control,” says the company….
Their ultimate ask is a ten-gram aircraft with a 7.5cm wingspan, which can carry a camera and explore caves and other potential hiding places. “It will need to fly at 10 metres per second and withstand 2.5-metre-per-second gusts of wind”

The micro-ornithopter/robot-insect concept has plenty of precedants in science fiction, and is another example of engineers borrowing from nature to solve engineering problems.

DARPA <3 Dune: miniature ornithopter in development

Paul Raven @ 03-07-2009

Chalk yet another one up to Frank Herbert; the DARPA people have just awarded a Phase II contract extension (whatever that means) to a company called AeroVironment so that they can continue developing their ‘Mercury’ Nano Air Vehicle ornithopter prototype. [via Hack-A-Day]

Ornithopters – which feature heavily in the Dune series – are aircraft that are propelled by flapping their wings like a bird rather than using rotors, propellors or jets. Check out the Mercury prototype in action:


Homebrew UAV: arduino

Tom James @ 07-02-2009

curvy_gridFlash forward 20 years. Everyone has access to an open-source personal rapid prototyper (notwithstanding a fabber equivalent of Bill Gates…) and can rustle up one of these homebrew UAVs: at the drop of a futuristic ambient computer thing:

Combined with a RC plane, this makes it easy to build a complete UAV for less than $500, which is really kind of amazing. As exciting as that it is, it’s also sobering to know that a technology that was just a few years ago the sole domain of the military is now within the reach of amateurs…

As Charles Stross points out, ready-to print Saturday night specials could be only a decade away, and along with the UAVs and the fabbers it makes the next few years an interesting time to be alive.

Raytheon in underwater UAV shocker

Tom James @ 27-10-2008

Kudos and congrats to the US military industrial complex for continuing to output such consistently high quality James-Bondworthy widgets and gizmos. The latest is an Unmanned Aerial Vehicle from arms megacorp Raytheon that can be launched from a submarine without having to surface:

The new U-UAV is dubbed SOTHOC, for Submarine Over the Horizon Organic Capabilities. The launch system works by deploying a sealed can through the sub’s waste disposal lock. The can then sinks away safely to get clear of the boat. On reaching a preset depth it dumps weight to become positively buoyant and ascends to the surface. Once stable at the surface, it aligns itself into wind and launches a one-shot, disposable UAV.

Gawd bless America for supplying the rest of the worlds military hardware geeks with a consistent supply of goodness with no only minimal risk to our own person (unless you live in one of the Axis of Evil countries).

Peace out.

Nothing says “future” like a big fat airship

Tom James @ 25-09-2008

As Charles Stross says, “Zeppelins have always been an icon of futurism” and I’ve always wondered why the heck we haven’t gotten over the Hindenburg and moved in to our Bright New Future. The Register gives us the lowdown on all the various engineering problems that need to be overcome for airships to be viable as a mass transport system, and how engineers are trying to solve them:

A Ukrainian airship visionary based in California has won further US military funding to develop his miraculous “Aeroscraft” sky-leviathan design. However, some question marks remain over the craft’s unique – almost miraculous – buoyancy-control technology.
