ABERDEEN PROVING GROUND, Md. (Aug. 25, 2017) -- Researchers from industry and universities across the nation have rallied around a collaborative technology alliance with the U.S. Army Research Laboratory since 2008.
A research program called Micro Autonomous Systems and Technology, or MAST, came to its conclusion during a capstone event of presentations and demonstrations of both ground and air micro-robots Aug. 22-24.
Teams of researchers gave 17 live demonstrations of the technologies they've been working on. The University of Pennsylvania showcased a group of autonomous quadcopters that self-organize into formations.
Officials said technology has advanced dramatically during the life of the program.
"I think there's still a long way to go to get them to do all of the behaviors we want in any type of environment," said Dr. Brett Piekarski, the Army's Collaborative Alliance Manager. "There are certain areas where I think we've really pushed the bar and moved the state-of-the-art. One example is in scaling things down to be able to do autonomous behavior in something that fits in the size of your hand.
Piekarski has been with the program since its inception and has managed the alliance of Army, industry and university researchers since 2012.
"In one way, I'm a little sad to see it end," he said. "In another way, I'm really excited because I think we pushed the boundaries of the state-of-the-art and we will be seeing the impact of the advancements within the program for years to come."
When the program started, the laboratory had several objectives. Scientists wanted to understand fundamental technologies that would to enable autonomous micro-robots to work together.
"Some things have matured quite a bit and other things I think we're still scratching the surface," Piekarski said. "There's been a lot of discovery and innovation. Proof-of-concept type things would be another area where I think we've done a lot of innovation in technology development."
"I am absolutely certain this technology will help the Soldiers of the future," said Allison Mathis, the program's deputy manager and an Army researcher with MAST for the past three years. "We have created advances in everything. There are new platforms, new algorithms, new sensors. Not all of this will be ready next year, or even the next five years, but we have absolutely advanced technology. We are making an impact right now."
MAST started as a five-year research alliance, which extended to 10 years, and brought together 19 partners from industry and academia. Lead defense contractor, BAE Systems, worked with the Jet Propulsion Laboratory on microsystems integration, The University of Michigan worked on microelectronics, while the University of Maryland focused on microsystem mechanics. The University of Pennsylvania targeted processing for autonomous operations.
Other consortium members were the University of California, Berkeley; Carnegie-Mellon University; Georgia Institute of Technology; University of New Mexico; Massachusetts Institute of Technology; Stanford University; Texas A&M University; University of California, Merced; University of Delaware; University of Texas, Austin; Kansas State University; University of Colorado, Bolder; Bowie State University; and University of California, San Diego.
"We've demonstrated what can be done in this space with some innovative ideas," Piekarski said. "There needs to be a lot of work in all of these areas to get them into engineered solutions that we can put in the hands of the Soldiers."
Piekarski said the lab will continue to work with its stakeholders and partners to "take it to the next level."
The Army recently announced its next focus area for a collaborative technology alliance to be known as Distributed Collaborative Intelligent Systems and Technology, or DCIST.
"It's really about high numbers of systems, heterogeneous in nature," Piekarski said. "So you think of it as air, ground, large, small, Soldiers in the loop...How do we do distributed intelligence? And then once we have that decision making, how do we get the information back out and control these large heterogeneous teams in complex and contested environments?"
Researchers said the next program will not be without challenges.
"If you have small, individual robots and you have instrumented Humvees and you have a person and you have maybe tens or hundreds or thousands of any of these things...How do they work together? How do you deal with attrition? How do they talk to each other? How does a fully instrumented Humvee talk to a tiny robot and talk to a person? This is not a simple problem. This is an incredibly difficult, exciting program."
Dr. Brian Sadler, the Army senior research scientist for intelligent systems said he is optimistic about the future.
"The convergence of technology that we're witnessing now, and as we propel it forward, is going to be a dramatic lifesaver and game-changer in terms of the way we operate tactically," Sadler said. "This is my opinion. I am extremely optimistic."
Sadler said it is important for the Army to stay out in front of the technology curve because autonomous robotics will soon be ubiquitous.
"We're now seeing a wave of commercialization in this space," he said. "It's going to change the way we do business. I believe this is going to be a tactical offset strategy for the Army - the miniaturization of the robotics, the combination of large and small platforms, what it brings to the networking, what it brings to sensing and the ability to go fast in complex environments, to be able to inject these into a scene ahead of the warfighter from overhead, from the ground, in and out of buildings at a very rapid pace. All of that is coming."
