I've written about self-organizing systems quite a bit in these pages over the years. So it's not surprising to me to see that someone has built robots that construct a building using these principles. The robots work completely autonomously, and following simple rules, build a building. They perform well in changing conditions. "Independently acting robots make for a robust system, he adds. “If some got swept away by the flood, the others wouldn’t have to change what they’re doing."
