An anonymous reader writes: The following video shows a swarm of 100 Kilobots solving a binary site-selection problem. The goal of the swarm is to decide between which of 2 sites has the highest quality and is thus more suitable for relocation. The viewer is introduced to the topic of collective decision-making starting with the preliminary results on the wisdom of the crowds of Sir. Francis Galton in 1906. Then, the video briefly describes the house-hunting behavior of honeybee swarms which functions as a biological inspiration for the proposed decision-making strategy.
