DARPA Wants to Give Soldiers Robot Surrogates, Avatar Style

In the movie Avatar, humans hooked themselves up to brain-machine-interface pods with which they could control giant genetically engineered human-alien hybrids. It's just a movie, but DARPA, the U.S. Defense Advanced Research Projects Agency, doesn't care: It wants this kind of system to be real, just replace "giant genetically engineered human-alien hybrids" with "robots."

In its 2013 budget, DARPA has decided to pour US $7 million into the "Avatar Project," whose goal is the following: "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.” Whoa.

That word "surrogate" implies something more than just telepresence, and indeed DARPA does specify that it is looking for "key advancements in telepresence and remote operation of a ground system." But we're perfectly free to speculate on what those "key advancements" are, which again comes back to "surrogate." To me, the implication is that there's going to be some technology that effectively puts the user "inside" the remote system, whether it's through immersive VR or exoskeleton or some sort of direct brain control. Either of these things is a realistic possibility, especially if DARPA's tossing a couple million at the problem.

And as for what this "semi-autonomous bi-pedal machine" is going to be, well... You remember that semi-autonomous bi-pedal machine that Boston Dynamics built for the U.S. Army to, uh, test chemical protection clothing? 

To be clear, we have absolutely no evidence to suggest that PETMAN is anything more than a chemical protection clothing tester, except for the simple fact that just testing suits seems like a slightly ridiculous use for a freakin' super-advanced bipedal humanoid soldier robot. In any case, it's always fun to speculate when DARPA throws a bunch of money at some crazy new technology, and hopefully we'll be lucky enough to see some preliminary results before an army of robotic surrogates takes over the world.

Boston Dynamics Takes Alpha Dog Military Robot Out For Its First Walk

First there were porters, then beasts of burden, then mechanized vehicles. And now we’re back to beasts of burden – and I mean beast! Yesterday Boston Dymanics took their Alpha Dog for a walk in the woods. After putting the LS3 prototype through the rigors of warehouse testing, like trying to kick it over with all their might, they decided it was ready for a real terrain test.

The Army considers physical overburden one of its top five science and technology challenges. Soldiers in the field can end up carrying gear weighing 100 lbs and the physical strain takes its toll. The LS3 (Legged Squad Support System) Alpha Dog is DARPA’s solution to lightening the solder’s load. But more than just navigating rugged terrain, yesterday’s demonstration tested the robot’s ability to follow a person using its “eyes,” a set of sensors that enable it to distinguish between trees or other obstructions and humans. You can actually see in the video that it follows the leader pretty well. With the strength to shoulder up to 400 lbs, the Alpha Dog will definitely be a soldier’s best friend. It also serves as a mobile power source that troops can use to recharge batteries for radios and other devices. It is still quite loud, however, so sneaking up on the enemy with Alpha Dog trailing probably wouldn’t be very smart.

This summer, DARPA and Boston Dynamics will begin an 18 month test period during which they will sharpen Alpha Dog’s capabilities. Its vision will be fine-tuned to follow individuals or designated objects and its ability to autonomously navigate over and around terrain obstacles will be evaluated. One planned test will see if Alpha Dog can complete a 20-mile trek while loaded with 400 lbs and without refueling. In addition to improving its vision, hearing technology will be added so that it can respond to commands like “stop,” “sit” or “come here.” At the end of testing, the robot will be given a chance to work with real Marines as they carry out field exercises. After watching the video, I’m pretty confident Alpha Dog will be ready.
