MARINE CORPS AIR STATION NEW RIVER, N.C. (June 27, 2006) -- On June 15 and 16, in a demonstration reminiscent of a new age science-fiction flick, a quadruped robot standing almost 3 feet tall descended down the ramp of an MV-22 “Osprey,” followed by a 50 pound hospital on wheels and a Marine in a wearable exoskeleton.
The first stunning display of technology is known as BigDog. This robot’s legs are articulated like an animal’s and absorb shock and recycle energy from one step to the next. BigDog has run at a rate of 3.3 mph, climbed a 35 degree slope and carried a 120 pound load.
“BigDog is going to someday, hopefully, give us the ability to have a mechanical mule to follow us around in the field and carry a couple hundred pounds of supplies,” said John Main, Defense Advanced Research Projects Agency program manager.
The idea behind BigDog is that machines with legs can get to places machines with wheels and tracked vehicles cannot, said Marc Raibert, president of Boston Dynamics, the company that has been working on BigDog with DARPA for the past three years.
From expeditionary missions to urban combat, where there are ladderwells, ditches and other barriers, DARPA intends to make this robot able to go anywhere a Marine can go, he said.
The Exoskeletons for Human Performance Augmentation Program is a wearable robot that gives its wearer mechanical arms and legs, said Main.
It gives him the ability to carry up to 200 pounds without feeling the load. The exoskeleton gives the Marine the ability to carry a lot more supplies, body armor, ammunition or anything that he would need to take with him in a place a vehicle cannot go, he explained.
“You can basically hang anything on the suit,” he said.
The third demonstration to roll off the “Osprey” ramp was the Life Support for Trauma and Transport-lite. The original LSTAT has been in operation since 1999; however, the LSTAT-lite is more affordable and not as heavy. At a mere 50 pounds, the LSTAT-lite is much more transportable than its 200 pound predecessor.
Main said he believes it is important for DARPA and the Marine Corps to work together so they can be sure that their research is going to benefit the Marines. The importance of performing the demonstration with the “Osprey” is so DARPA’s researchers can see how it all will work together and the only way to do that is to try things out, he said.
Although any three of these devices could have jumped off the pages of a sci-fi novel rather than the back ramp of an Osprey, DARPA brought them all to life and right here on New River.
“If it’s possible in our minds to make it happen, DARPA can do that for Marines,” said Lt. Col. Ed Tovar, DARPA program manager. “The great thing about Marines is we always think there’s a better way to do things and DARPA helps us do that.”
