Army-funded researchers at the Harvard Microrobotics Laboratory are popping out Harvard Monolithic Bees ("Mobees") from multi-layered, laser-cut blocks about the size of a quarter.

Inspired by pop-up books, the manufacturing process could allow for rapid production of dozens of flying robots and other electromechanical devices. The research is being published in the March edition of the Journal of Micromechanics and Microengineering.

In the RoboBees project, Pratheev Sreetharan and colleagues want to build bee-size robots that can fly and act autonomously as a colony. Until recently, it used a painstaking manual assembly method.

The prototype sheets consist of 18 layers of carbon fiber, titanium, brass, ceramic, adhesive sheets, and the plastic film Kapton. As seen in the vid below, the bee snaps together as it pops out of the laminate. … Read more

Could soldiers of the future fight battles in robot bodies controlled from afar? DARPA apparently thinks so, and the agency wants to create an army of surrogate fighting droids.

The U.S. military's research wing apparently is planning surrogates like in the film "Avatar" but with robots instead of giant Na'vi. It has a $7 million program code-named "Avatar" in its 2013 budget, according to Wired.

The robots would reduce risk to human fighters, just as thousands of aerial drones are already keeping pilots out of harm's way. … Read more

It sounds like a particularly suspicious late-night infomercial: Spray your way to a better wireless signal! Improve your range! Save battery! Transmit over great distances under water!

But Chamtech's spray-on antenna is a real product with some impressive claims. It can be sprayed on almost any surface, even trees and orange barrels. It doesn't suck up power. It works in a mysterious nanotech way.

Here's how I imagine the antenna process goes:… Read more

Remember the original BigDog? That funny robot pack animal? Well, a supersized version has been let off the leash--and it ain't so funny anymore.

We last saw the brute when Boston Dynamics unveiled the AlphaDog prototype last year. Even in a harness, it looked pretty mean and could haul 400 pounds without even panting.

This latest incarnation, though, makes its predecessor look quite poodle-like. As seen in the video below, DARPA recently took AlphaDog, aka the Legged Squad Support System, or LS3, out for a walk in the woods and probably scared off every living creature for miles around. … Read more

If there's one medium that you wouldn't expect to see get taken on by graffiti and other contemporary artists, it's military airplanes.

But thanks to the folks behind the Round Trip: Art from the Boneyard Project exhibition, now on display at the Pima Air & Space Museum in Tucson, Ariz., visitors can see just that.

Although only five full airplanes have been painted--out of dozens in the museum's full collection--the show also includes two cockpits and a large group of airplane sections, all reimagined with an artist's flair. The exhibition, which runs through May 31, &… Read more

Within five years, soldiers who suffer facial burns could have their faces regrown by wearing intelligent biomechanical masks, according to research out of the University of Texas at Arlington.

Eileen Moss of the university's Automation & Robotics Research Institute is collaborating with the U.S. Army and Northwestern University to build a prototype Biomask equipped with tiny sensors and actuators.

Under conventional treatment, damaged tissue is removed and replaced with grafts. The procedure, however, can sometimes produce speech problems, deformities, and scarring; it can require multiple operations.

The Biomask consists of a rigid, face-shaped shell and covering flexible polymer layers that contain arrays of electrical and mechanical components. … Read more

A new design for a self-guiding bullet could allow sharpshooters to accurately fire at targets a full mile away.

The bullet, which is still in a prototype phase, is the brainchild of Sandia National Laboratories researchers Red Jones and Brian Kast. It is designed with built-in actuators and tiny fins that should allow it to rapidly adjust its path in flight.

Designed with the military, law enforcement, and recreational shooters as potential customers, the bullet is four inches long and has an optical sensor embedded in its nose for the detection of a laser on its target, Sandia said in … Read more

As machines that let first responders look at dangerous objects become increasingly common, Novatiq has started producing a throwable recon robot with the relatively low price tag of roughly $11,300.

The military-grade Scorp was announced last year with slightly different specs. At 13 inches long and 7.7 pounds, it's compact and light enough for backpack portability.

It's also tough enough to be thrown into buildings and dangerous areas, just like the lighter 110 FirstLook from iRobot.

Both machines are remote-operated, roll on treads, and have flippers that enable them to climb stairs, train tracks, and other … Read more

DARPA's list of projects reads like a sci-fi writer's dream. The federal agency has studied flying cars, starships, and cyborg insects. Now you can add a magic wand flame suppressant to the agenda.

A Defense Advanced Research Projects Agency research team at Harvard University created a handheld electrode that puts out fire with no water, chemicals, or smothering.

Details are sketchy as to how exactly the Harvard wand, whose technology may eventually find its way into fire suppression systems for military ships and vehicles, works. We do know, however, that the Instant Fire Suppression program is looking at the feasibility of using electromagnetic fields, ion injection, and acoustics to put out flames. As DARPA so poetically explains, flames are just "cold plasmas comprising mobile electrons and slower positive ions."

There's something very Harry Potter-ish about the flame suppression wand. I almost expected to hear a scientist muttering, "Aguamenti!" during the demonstration video, below.… Read more
