Swarm of autonomous drones and ground robots cuts off “city hall” in test

DARPA “swarmed” and isolated a mock city hall with autonomous aerial drones and ground-robots, the agency announced.

The aim of the exercise was to “establish a boundary…around a focal point” in a similar way to firefighting crews cutting off a burning building.

Tasks for the AI-controlled craft included locating and securing an objective inside, and then securing the building – all while maintaining situational awareness of the surrounding area with runs lasting up to 30 minutes each.

It was the second field experiment of its OFFensive Swarm-Enabled Tactics (OFFSET) programme. OFFSET envisions large swarms of collaborative autonomous systems such as unmanned aerial vehicles (UAVs ) and unmanned ground vehicles (UGVs )providing critical insights to small ground military units in urban areas where vertical structures, tight spaces, and limited sight lines constrain communications and mobility.

The program includes multiple “sprint” efforts, which focus on different elements of the command, control, and collaboration among large numbers of vehicles and humans.

For the experiment, which took place at the Selby Combined Arms Collective Training Facility in Fort Benning, Georgia, teams undertook a complex scenario spanning two city blocks. Tasks included locating and isolating a mock city hall building,

OFFSET includes two main performer types: Swarm System Integrators and Swarm Sprinters. The Swarm System Integrators, Northrop Grumman and Raytheon BBN, create OFFSET architectures, interfaces, and their respective Swarm Tactics Exchanges, which houses tools to help performers design swarm tactics by composing collective behaviors, swarm algorithms, and existing swarm tactics. The Swarm Sprinters perform focused tasks and deliver additional technologies to merge with system integrators.

The latest event brought together the integrators and second set of Swarm Sprinters, including Heron; Michigan Tech Research Institute; University of North Carolina, Charlotte; and Cornell University, to integrate and test swarm autonomy tactics and technologies.

“The pace of our scheduled experiments requires our performers to take risks” said Timothy Chung, the OFFSET program manager in DARPA’s Tactical Technology Office. “Rapid integration demands that our swarm teams, both integrators and sprinters, develop smarter ways to improve their current processes.”

The experiment at Fort Benning highlighted the benefits of continuous agile development and integration and deployment, the principle at the heart of the OFFSET program. The Swarm System Integrators showed maturation in field operations while the Swarm Sprinters contributed technologies to enhance system performance. The platform experimentation provided insights into the role of commercial-off-the-shelf technologies in a research and development program.

The recent field experiment was the second of six scheduled tests. Additional field experiments are targeted at intervals about six months apart.

DARPA has awarded contracts for the next Swarm Sprint to develop novel approaches to Human-Swarm Teaming over the next six months to demonstrate in the next OFFSET field experiment. The awardees are Case Western Reserve University, Charles River Analytics and Northwestern University. Each of the planned five core “sprints” focuses on one of the key thrust areas: Swarm Tactics, Swarm Autonomy, Human-Swarm Teaming, Virtual Environment, and Physical Testbed. Each Swarm Sprint topic emphasizes different perspectives to ultimately enable breakthroughs in swarm capabilities.
