DARPA aims to give small unmanned aerial vehicles advanced perception and autonomy to rapidly search buildings or other cluttered environments without teleoperation.

Micro aerial vehicles based on insects and birds are likely to enter military use in the next few years. The US agency DARPA is planning a new generation of small, fast, agile flying vehicles – able to quickly navigate a maze of rooms, stairways and corridors or other obstacle-filled environments without a remote pilot.

Military teams patrolling dangerous urban locations overseas and rescue teams responding to disasters like earthquakes or floods currently rely on remotely piloted unmanned aerial vehicles to provide a bird’s-eye view of the situation and spot threats that can’t be seen from the ground. But to know what’s going on inside an unstable building or a threatening indoor space often requires physical entry, which can put troops or civilian response teams in danger.

To address these challenges, DARPA has issued a Broad Agency Announcement for its Fast Lightweight Autonomy (FLA) program. This will focus on creating a new class of algorithms, enabling the development of autonomous drones small enough to fit through an open window and fly at speeds up to 20 metres per second (45mph) – while navigating complex indoor spaces, independent of communication with outside operators or sensors and without reliance on GPS waypoints.

“Birds of prey and flying insects exhibit the kinds of capabilities we want for small UAVs,” says Mark Micire, program manager. “Goshawks, for example, can fly very fast through a dense forest without smacking into a tree. Many insects, too, can dart and hover with incredible speed and precision. The goal of the FLA program is to explore non-traditional perception and autonomy methods that would give small UAVs the capacity to perform in a similar way, including an ability to easily navigate tight spaces at high speed and quickly recognize if it had already been in a room before.”



If successful, the algorithms developed in the program could enhance unmanned system capabilities by reducing the amount of processing power, communications, and human intervention needed for low-level tasks, such as navigation around obstacles in a cluttered environment. The initial focus is on UAVs, but advances made through the FLA program could potentially be applied to ground, marine and underwater systems, which could be especially useful in GPS-degraded or denied environments.

“Urban and disaster relief operations would be obvious key beneficiaries, but applications for this technology could extend to a wide variety of missions using small and large unmanned systems linked together with manned platforms as a system of systems,” says Stefanie Tompkins, director of DARPA’s Defense Sciences Office. “By enabling unmanned systems to learn ‘muscle memory’ and perception for basic tasks like avoiding obstacles, it would relieve overload and stress on human operators so they can focus on supervising the systems and executing the larger mission.”

DARPA has scheduled a Proposers’ Day webcast on Tuesday 6th January 2015.
