Eciton robotica: Design and Algorithms for an Adaptive Self-Assembling Soft Robot Collective

Social insects successfully create bridges, rafts, nests and other structures out of their own bodies and do so with no centralized control system, simply by following local rules. For example, while traversing rough terrain, army ants (genus Eciton) build ...
