Quadrotor Learns How Not To Swing Stuff
One of the ways in which robots are just starting to get really useful is with hauling aerial cargo. Last year, the optionally-manned KMAX made its first autonomous cargo delivery in Afghanistan, and since it can fly as many missions as you have fuel to keep it going, it's definitely a safer and more efficient way to get supplies to troops, especially in dangerous areas.
To move cargo around, helicopters (autonomous or otherwise) often carry stuff slung beneath them on long ropes, and as you can probably imagine, said cargo often ends up doing all sorts of swinging about, especially if the helicopter that's carrying it has to maneuver. Researchers from the University of New Mexico have been developing algorithms that allow robots to compensate for motion-induced swinging of suspended loads, and testing them out on real live quadrotors.
