Social insects like ants and bees exhibit sophisticated collective intelligence through problem solving. For example, ants use pheromone trails to mark routes to food sources, with more traveled paths attracting more ants over time. The problems social insects solve, such as finding food and building nests, relate to engineering and computer science issues. Swarm intelligence takes inspiration from social insects by combining many simple robots to achieve complex behaviors, with potential applications including military operations, health, manufacturing, and space exploration. For instance, exploring the solar system may require deploying many small robots that can replicate themselves and build new vehicles.
