MIT researchers are trying to get computers to correctly interpret hand signals used by crews aboard aircraft carriers so that robot planes can follow them.

As Northrop Grumman continues to develop its X-47B robot stealth plane, which is aimed at carrier use, Yale Song and colleagues at MIT are working on a machine learning system that could allow autonomous planes to understand crew directions.

In its research presented in the journal ACM Transactions on Interactive Intelligent Systems, the team used a database of abstract representations of 24 gestures often employed by carrier personnel. They trained an algorithm to classify gestures, including posture and hand position, based on what it knew from the database. … Read more

DARPA is quickly becoming the supplier of my nightmares.

As if the monstrous AlphaDog wasn't intimidating enough, it now has a feline friend, the "Cheetah," that will certainly have you running for the hills. Chances are you won't be able to outrun it, though.

Created by Boston Dynamics, Cheetah is allegedly now the fastest legged robot on the planet. DARPA released a video today showing the bot running at various speeds on a laboratory treadmill, ultimately hitting its maximum speed of 18 mph. This breaks the previous land-speed record of 13.1 mph set back in 1989. … Read more

The U.S. Air Force plans to replace some of its paper manuals with digital editions in the cockpit, and has just laid down the funds to make that happen.

Bloomberg reports that Phoenix-based Executive Technology was awarded a $9.36 million contract from the Air Force today, which it plans to use to purchase iPads that will then be loaded up with flight manuals and navigation software.

The move follows a request for proposals put out by the Air Mobility Command last month, asking for digital replacements for in-flight materials.

In an interview with Bloomberg, a military spokeswoman said … Read more

The U.S. Air Force yesterday gave the go ahead to begin "introductory" flight tests of its version of the F-35A Joint Strike Fighter, a major step forward for the trillion-dollar program that, Wired reports, is expected to succeed nearly all of the Pentagon's tactical jets over the next three decades.

If you think maybe you read that number wrong, let me repeat: a trillion dollars. According to Reuters, the F-35 program is seen as a fleet of 2,443 jets over the next 50 years, a flying armada that is expected to cost $1 trillion over … Read more

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
