A murmuration of robots, a huddle of penguins. Swarm behaviour is a sticky problem. Scientists are twisting their brains to come up with self-organising systems. The murmuration of starlings, the behaviour of slime moulds, ants and corals are examples of nature being waaaay ahead of us. Here, Harvard University has created a self-organising system, consisting of 1024 (magic number!) tiny robots. They are a long way away from the sterlings, but there is something really adorable about seeing those little robots getting in line.
Basically, what these robots are doing, is a version of the emperor penguins’ “huddle”: to keep themselves and their chicks warm in the depth of winter, the (male, actually) penguins shuffle and ripple around in a massive pile. It keeps everyone from freezing to death. Besides, it looks adorable:

Slime molds will always somehow find the shortest way to food, and can be used to create complex networks such as urban communications. Here is a video of a slime mold describing the Tokyo metro. More information about that project here.
We are smart creatures, but nature usually gets there first, without smarts.
