A robot learning to flip pancakes from Sylvain Calinon on Vimeo.

Through the process of reinforcement learning (that is, learning by practicing over and over and over again), this robot has somewhat mastered the art of flipping a pancake. It’s cool that the robot takes what it learns from an actual human being and then fine-tunes it to each individual instance of the pancake being tossed into the air. It took some time, but it looks like it successfully gets the job done. I still wouldn’t trust it in my kitchen though.
