Service Academies Swarm Challenge Live-Fly Competition Begins
by Staff Writers
Washington DC (SPX) Apr 26, 2017


This data visualization portrays the swarms of unmanned aerial vehicles that flew today over Camp Roberts, Calif., while implementing autonomous swarm tactics designed by Cadets at the U.S. Military Academy and the U.S. Air Force Academy for the DARPA Service Academies Swarm Challenge. U.S. Army, U.S. Navy, and U.S. Air Force academy teams are competing in an education-focused experiment designed to pave the way for future offensive and defensive swarm tactics for warfighters.

Small unmanned aerial vehicles (UAVs) and other robots have become increasingly affordable, capable, and available to both the U.S. military and adversaries alike. Enabling UAVs and similar assets to perform useful tasks under human supervision-that is, carrying out swarm tactics in concert with human teammates-holds tremendous promise to extend the advantages U.S. warfighters have in field operations.

A persistent challenge in achieving this capability, however, has been scalability: enabling one operator to oversee multiple robotic platforms and have them perform highly autonomous behaviors without direct teleoperation. To help make effective swarm tactics a reality, DARPA created the Service Academies Swarm Challenge, a collaboration between the Agency and the three U.S. military Service academies-the U.S. Military Academy, the U.S. Naval Academy, and the U.S. Air Force Academy.

An experiment at its heart, the research effort is designed to encourage students to develop innovative offensive and defensive tactics for swarms of small UAVs. Today the effort started its three-day Live-Fly Competition at Camp Roberts, a California Army National Guard post north of Paso Robles, Calif., which is hosting more than 40 Cadets and Midshipmen to demonstrate the highly autonomous swarm tactics they have developed since work started in September.

"In less than eight months, you have shown yourselves to be dedicated and talented participants in a complex and timely research effort," Timothy Chung, the DARPA program manager leading the Swarm Challenge, told the teams.

"DARPA is proud to have you-our future warfighters and Service leaders-participating in this endeavor to explore offensive and defensive swarm tactics. Now is your chance to show each other, DARPA, and our invited Defense Department guests your precedent-setting work toward an important goal: helping future U.S. forces maintain superiority in tomorrow's technological and mission environments."

"Not to mention your chance to claim bragging rights over your rival academies," he added. Teams

The Service Academies Swarm Challenge is the most recent example of how DARPA works to ensure the technological superiority of U.S. military forces by periodically engaging the U.S. military Service academies in research-oriented competitions. These competitions aim to cultivate the great potential of young officers-to-be and encourage their career-long collaboration with DARPA. In both 2014 and 2015, for example, DARPA conducted the DARPA Service Academy Innovation Challenge and the Service Academies Cyber Stakes.

A fourth-year capstone design course, the Swarm Challenge has pushed students to achieve "zero to swarm in eight months." The goal: help the academies go from having little swarm-related expertise to developing capabilities with potentially near-term applicability for operational training and fielding-all within one academic year.

"This is one of the first opportunities for the next generation of operators and tacticians to explore and understand swarm-versus-swarm interactions," Chung said. "It's not just about the platforms or the links or the communications-it's about behaviors. That's one of the key takeaways for the Service Academies Swarm Challenge: that we're really zeroing in on swarm tactics as a battle skill. That's where advances will reap innovative benefits for future warfighters."

Ranging in size from 11 to 21 students, the teams bring cross-disciplinary expertise in diverse technical and nontechnical fields, from computer science, robotics, and systems engineering to military strategy and operations. The students also bring fresh insights that DARPA and the U.S. military can learn from-and potentially expand upon-to enhance the tactical effectiveness of swarm systems.

DARPA provided all the hardware, much of the software, and a lot of know-how to get the teams started. The Agency also developed new support infrastructure to enable the teams to practice and compete in a virtual environment in preparation for this week. DARPA initially provided some example swarm tactics and the teams have since designed a number of their own to debut at the Live-Fly Competition.

Gameplay
The Service Academies Swarm Challenge is testing cutting-edge swarm tactics through a time-honored game that is all about tactics: Capture the Flag. Two teams at a time play inside the Battle Cube, a cubic airspace 500 meters on a side, 78 meters above the ground. Each team has been given 20 fixed-wing UAVs and 20 quad-rotor UAVs and, under the rules of play, can field a mixed fleet of up to 25 UAVs for each of two 30-minute battle rounds. Each team protects its "flag" (a large, inflatable ground target) while trying to score the most points before time runs out.

Teams seek to score the most points in the following ways:

+ Air-to-air "tags" by using a simulated (virtual) weapon to hit a sensor on an opponent's UAV in flight

+ Air-to-ground "tags" by physically landing a UAV on the opponent's "flag" located on the ground

+ Accomplishments in swarm logistics by launching as many UAVs as quickly as possible and keeping them aloft as long as possible

As scheduled over the next three days, the first match pits Air Force against Army; the second, Army plays Navy, and the third match has Navy squaring off against Air Force. The team that wins both of its matches wins the competition and takes home a trophy and bragging rights.

Technical Challenges
While people often think about swarms as simply being large collections of robots, swarms in fact have five defining characteristics: number, agent complexity, collective complexity, heterogeneity, and human-swarm interaction. The Service Academies Swarm Challenge is designed to explore these characteristics as they apply to both offensive and defensive swarm tactics, and to harness and leverage them for warfighter benefit.

Operationalizing swarm-related capabilities poses many significant challenges, from technology (e.g., battery size and life, user interfaces) to logistics (e.g., transport, upkeep) to understanding the limitations of what swarms can do. The Swarm Challenge provides an experimental testbed that manages these challenges so the academy students can focus on creating innovative swarm tactics.

DARPA's interest in developing breakthrough swarm capabilities for national security extends beyond the Swarm Challenge to a number of current programs exploring autonomy, communications, and other technologies, including:

+ Collaborative Operations in Denied Environment (CODE)

+ Fast Lightweight Autonomy (FLA)

+ OFFensive Swarm-Enabled Tactics (OFFSET)

Looking Ahead
The results of the Live-Fly Competition remain to be seen but the Service Academies Swarm Challenge has already planted the seeds for future growth in the increasingly important domain of swarm tactics.

Thanks to the past eight months of work, all three academies now have basic curricula and frameworks for conducting unique, accelerated research and field experiments on swarm tactics. The institutions also have dozens of students who have worked side-by-side with leading-edge researchers and operators experienced with advancing the state of knowledge of swarm systems.

"The Cadets and Midshipmen participating in the Service Academies Swarm Challenge will soon be officers, where they can further hone their swarm-tactics skills and share their know-how with fellow Service members," Chung said.

"Building on the lessons they have learned, they can help accelerate us toward a near future in which Service members are able to quickly take advantage of anticipated advances in unmanned aerial system technologies and apply their skills in new and ever more creative ways. No matter which academy comes out on top here, U.S. warfighters will be the ultimate winners."

MQ-8C Fire Scout takes first flight from littoral combat ship
Washington (UPI) Apr 17, 2017
The MQ-8C Fire Scout, an unmanned helicopter being built for the U.S. Navy, took its first flight from a littoral combat ship earlier in April. The sea trials took place off the coast of California aboard the Independence-class vessel USS Montgomery, and follows an earlier flight test aboard guided-missile destroyer USS Jason Dunman. Manufacturer Northrop Grumman says the event puts the ... read more
