DARPA figures that since raptors like the Goshawk can dart through dense forests effortlessly, why not study them for drone design ideas? That could lead to algorithms that would let UAVs "easily navigate tight spaces at high speed and quickly recognize if it had already been in a room." It also wants the UAVs to be able to do all that with a minimum of calculation, communication and human action required. And though the program is strictly aimed at drones for now, DARPA thinks it could also be used in ground- and marine-based remote systems, especially when there's little-to-no GPS availability. That way, if a drone can't help in a tense situation, the military could always send in the Big Dogs.
