This isn't about UAVs per se, but for students of control theory, the physics of a double pendulum (hinged in the middle) is an example of chaotic motion and notorious hard to model. Well, this guy did it. Keep watching...this is mindblowing.

That is the coolest video I have ever seen.

It's a freaking awesome nice research! (and the music too...)

Awesome! It reminds me of some work in the 90's by Stanford Prof Bernard Widrow's group. They had worked out a neural network that can back up a truck+trailer, and then they extended it so that an RC truck+trailor could be driven backwards. I saw an actual demo of that in one grad student's basement. Essentially the controller would enforce a turning radius based on the input steering signal. I think for his thesis he was going to next try a double trailer. He got it working a little in simulation but I don't know about in reality.

Wow! I had a lot of fun with the inverted pendulum as an undergrad, but the idea of a double pendulum makes me cringe. Well done!

Yes, that is impressive, and it just serves to show that eventually, when the humans in the back seat consider it "The New Way It's Alway Been(tm)", autonomous aircraft will be the norm in the air.
