Resumen de Robot swarms build towers with no human
A swarm of robots scuffles across the bench. Working together, each one scoops a styrofoam block on to its back and then climbs a growing layer of blacks to flip its new one into place. Slowly, a tower rises up. It's impressive--especially as they are doing this without any human control at all. All they have to go on are simple rules about the environment around them. What's more, the bodies of these shoe-sized robots have been 3D printed, making them cheap and easy to reproduce. Their hooked wheels, good for climbing and grasping, also let them trundle on the flat.
