DARPA says that the UAV uses a commercial DJI Flamewheel fitted with a 3DR Pixhawk autopilot for the airframe, among other adornments. Perhaps most impressive is that this unit is able to hit speed even carrying sonar, inertia sensors and an HD camera on such a small frame. Oh, and the demo flight in the video below was entirely autonomous. That's right, zero pilots were involved in getting the drone around the stacks of boxes and whatnot here.
Steve Vance says
My biggest problem with this is the accidents happen part. I don't want to be the accident that turns a corner as this little bastard is doing 45 mph and wap.
