They're called QRIOs, so-called "dream robots" developed by Sony Japan as high-tech playthings for children. The QRIO can carry on conversations, adapt to a multitude of environments and - most importantly - mimic human movements, including complex dance routines. Currently, there are only four working QRIOs in the world. And all of them appear in the brand new video from Beck "Hell Yes".
