DARPA's fully-loaded quadcopter autonomously navigates an indoor maze at 45 mph

DARPA recently flew a fully-laden quadcopter through an indoor obstacle course at 45 mph (32 km/h) as part of the agency's Fast Lightweight Autonomy (FLA) program. The test flight was conducted entirely under autonomous control with the goal of developing small unmanned aerial vehicles (UAV) with the ability to navigate through tight spaces without the need for outside control or GPS.

If left to occur naturally, the process takes several hours, limiting its practicality. Now, however, scientists at the University of Alberta's Faculty of Engineering have developed a method of doing so within 15 milliseconds.
