This wonderful BBC footage captured with a camera mounted on a Northern Goshawk flying through a densely wooded area is being used by the Defense Advanced Research Projects Agency (DARPA) as an illustration of in-development unmanned aerial vehicle (UAV) technology.
The new project, named the Fast Lightweight Autonomy program, involves UAVs compact enough to fit through windows to fly up to 45 miles per hour, all the while making their way through hard-to-navigate indoor spaces without the aid of GPS points or other communications.
Much like robotics, it's often the case that developing technology is based on the incredible movement of animals; mechanics modeled upon nature.
