The military research agency has announced the second "sprint" of its OFFensive Swarm-Enabled Tactics (OFFSET) program. Sprints are periods in a program when DARPA announces a main theme and asks for related solicitations or prototypes in the hopes of getting faster technological breakthroughs.
Whereas the first sprint focused on swarm tactics, this sprint's theme is swarm autonomy. DARPA is fishing around for concepts that can allow drones to talk with each other and work as as a well-oiled team of lean, mean, killing machines with little in the way of human supervision.

These ideas could be built around more capable sensors, smarter software, or more efficient propeller blades. If it allows 50 individual drones to function as a coordinated swarm that can secure an area around the size of a couple of city blocks within 30 minutes, it's in.
According to OFFSET program manager Timothy Chung, the drone swarm will be responsible for setting up a safety bubble around the target area. He likens it to how a fire-fighting crew creates a safe perimeter around an ongoing fire in order to give themselves elbow room to fight the conflagration while also making sure everyone else stays outside the danger zone.
DARPA wants suggestions about the best size for that perimeter, how drone teams can enforce those boundaries, and the ability of drones to adapt to sudden changes in the situation. Furthermore, the technology must be applicable in "complex urban environments" such as high rise buildings, industrial and commercial areas, or sprawling residential areas.
To achieve that end, integrators Raytheon and Northrop Grumman will provide the drones platforms. Meanwhile, the companies and research groups tapped for the prints will look for ways to enhance the capabilities of those robots, be it in tactics or tech.
“Sprinters will develop approaches (the tactics) to achieve the desired capabilities within the integrator-developed hardware and software architectures,” explained Chung. He adds that sprinters can also ask for extra parts or drone types if those could benefit the swarm's operations.
The current sprint will be followed by three more: Human-Swarm Teaming, Virtual Environments, and Physical Testbed.
The ultimate goal of DARPA's OFFSET program is to place the ability to control swarms of hundreds of unmanned aircraft and ground drones in the hands of groups of soldiers on the ground. The drones can check out the city, map out the intended area of operations, identify potential hostiles, and protect against any attacks.
Soldiers will keep track of hundreds of drones through a human-swarm interface that uses both augmented reality and virtual reality. They will be able to control any or all of the drones using voice commands, gestures, and touch screens.
To train soldiers in the use of such a powerful force of robots, the project will develop a swarm tactics war game that uses the same human-swarm interface. "Players" can test out tactics in a virtual environment and keep track of their performance on a leader board, which encourages both cooperation and competition between users.
Finally, DARPA wants to cultivate a community where users can talk with each other on drone swarm tactics and share their experiences on what works and what doesn't.
