This looks like a very promising research avenue, and I don't mean to deprecate it in any way. But this part of the article seemed a bit too pollyannish: "Currently the system hasn’t been tested on a full-scale helicopter, used instead on a rather large remote- control hobby vehicle. But as the technology fundamentally works in the same way, there’s no reason to believe this won’t make its way onto full-sized helicopters in the future." It's not self evident to me that, at the scales necessary for use in human-piloted helicopters, the robotic legs would be light enough to avoid causing thrust-to-weight ratio problems. But as always, I'm rooting for DARPA to make it work!
