Video: DARPA drones swarm building

Teams of small autonomous quadcopters, in coordination with groups of small wheeled ground vehicles, swarmed building in a tactics test at Fort Benning, Georgia in June.

The unmanned air vehicles (UAV) identified locations of interest and then created a perimeter around a focal point, says the Pentagon’s Defense Advanced Research Projects Agency (DARPA) on 7 August. The drones moved similar to the way a firefighting crew establishes a boundary around a burning building, the agency says.

The test was the second field experiment for DARPA’s OFFensive Swarm-Enabled Tactics (OFFSET) programme. OFFSET envisions small infantry units teaming with swarms of more than 250 UAVs, and possibly with unmanned ground vehicles, to execute tactical missions in complex and difficult urban environments.

DARPA believes UAVs and unmanned ground vehicles could give critical insights to small ground military units during urban warfare. In cities, tall buildings, tight spaces, and limited line-of-sight make it difficult for soldiers to communicate and manoeuvre. With more than half of the world's population living in cities today - a portion that is projected by the United Nations to rise to two-thirds by 2050 - the US military is preparing for potential battles in metropolitan areas.

For the recent experiment, teams undertook tasks including locating and isolating a mock city hall building, locating and securing an objective inside, and then securing the building. Those tasks had to be completed while maintaining situational awareness of the surrounding area. Test runs lasted up to 30min.

The results of the experiments were not disclosed by DARPA.

Participants in the latest experiment included Heron Systems, Michigan Tech Research Institute, University of North Carolina in Charlotte and Cornell University

The field experiment was the second of six scheduled tests, which are planned to take place every six months.
