Soldiers practically inhabiting the mechanical bodies of androids, who will take the humans’ place on the battlefield. Or sophisticated tech that spots a powerful laser ray, then stops it from obliterating its target.
If you’ve got Danger Room’s taste in movies, you’ve probably seen both ideas on the big screen. Now Darpa, the Pentagon’s far-out research arm, wants to bring ‘em into the real world.
In the agency’s $US2.8 billion budget for 2013, unveiled on Monday, they’ve allotted $US7 million for a project titled “Avatar”. The project’s ultimate goal, not surprisingly, sounds a lot like the plot of the same-named (but much more expensive) flick.
According the agency, “the Avatar program will develop interfaces and algorithms to enable a soldier to effectively partner with a semi-autonomous bi-pedal machine and allow it to act as the soldier’s surrogate.”
These robots should be smart and agile enough to do the dirty work of war, Darpa notes. That includes the “room clearing, sentry control [and] combat casualty recovery.” And all at the bidding of their human partner.
Freaky? Um, yes. But the initiative does strike as the next logical step in Darpa’s robotics research. For one thing, the agency’s already been investigating increasingly autonomous, lifelike robots, including Petman (a headless humanoid), designed to mimic a soldier’s physiology, and AlphaDog (a gigantic, lumbering, four-legged beast), meant to lug gear during combat.
And just last week, when Darpa released a new video of AlphaDog cavorting through the forest, the agency noted that they wanted the ‘bot to “interact with [soldiers] in a natural way, similar to the way a trained animal and its handler interact.” AlphaDog is even being designed to follow a human commander using visual sensors and respond to vocal commands.
Based on Darpa’s description of the “Avatar” project, which notes “keyadvancements in telepresence and remote operation of aground system”, it sounds like the agency’s after an even more sophisticated robot-soldier synergy. They don’t specify the means, but Darpa’s already funded successful investigationsinto robots that are controlled with mind power alone. Granted, that research was performed on monkeys. But it does raise the tantalising prospect that soldiers might one day meld minds with their very own robotic alter egos.
And the “Avatar” project isn’t Darpa’s only nod to sci-fi in their new budget plan. The agency’s “Counter Laser Technologies” project, on which they’re spending $US4.1 million, seeks to develop “laser countermeasures” that’d protect the military’s weapons from high-energy lasers, and maybe even thwart potential attacks. No, Death Stars are not specifically mentioned.
Of course, such super-powerful blasters aren’t yet combat-ready. (Just ask the Army, which has a $US38 million laser cannon — without a laser; it’s complicated.) But once they are, the lasers could do some serious damage to existing weapons systems, which is why the Pentagon’s already been after methods that’d safeguard its existing arsenals. In 2008, for example, the Air Force asked scientists to develop laser-proof coatings for weaponry. The US Navy in 2009 also launched its own counter-laserinitiative, looking for ideas to protect against myriad different blasters, high-energy lasers included.
Darpa’s project will try to accomplish some of those same goals. For example, the agency mentions an interest in “material treatments” that’d protect weaponry from a laser able to “melt through, fracture or weaken the body.” But Darpa’s also looking for a more comprehensive array of tools. It wants “warning systems” that can detect high-energy lasers, and “determine the attributes of the threat” (including wavelength and power). Plus, the agency’s after technology that can thwart a laser attack entirely, by “altering the laser’s internal optics or modifying the laser’s line of sight.”
Clearly, a leaner Pentagon budget hasn’t stopped Darpa’s dreamers from watching too much sci-fi. We’re just hoping nobody at the agency’s seenSource Code.
