Nature has once again proven to be an efficient designer, showing time and again how ant teamwork is much better than that of humans. Macquarie University behavioural ecologist Madelyne Stewardson and her team decided to investigate whether asian weaver ants (Oecophylla smaragdina) are also afflicted by the Ringelmass effect. Macquarie University behavioral ecologist Chris Reid analyzed how weaver ant colonies worked together when building their nests. In their newly developed “force ratchet” theory, the team believes that this organization allows the ants to contribute more individually as the team grows. But the force ratchet theory from weaver ants could inspire designs for even more efficient robot teams.
