If the movies have taught us anything, it’s that the future isn’t just about robots–it’s about robots that can heal, adapt, and change their entire appearance at a moment’s notice. In a future directed by Michael Bay, that plays out as a semi-truck reconfiguring itself into a bipedal fighting machine halfway through a front-flip. For now, though, the action is a little more modest. In this clip, we see the real state of the art in self-assembling bots: a bunch of little magnetic cubes scuttling around a tabletop. It’s much cooler than it sounds.
