The Best in Science News and Amazing Breakthroughs
Have you ever been part of a large group project? You might assume that with more people involved, the work gets done better and faster. However, as more team members join the group, the effectiveness of each individual doesn't increase.
It doesn't even stay constant – it gets worse. Many hands may make light work, but too many cooks spoil the broth.When he measured the force produced by students pulling on a rope, he found that as more students joined the task, the total pulling force increased – but the average effort per individual decreased.But many animal species, from fish schools to lion prides, cooperate successfully in large groups. Could they somehow overcome this decline in efficiency?Ants are champions of collective action, seamlessly coordinating complex tasks across colonies of millions. And among all ant species, the weaver ants Our research has broad implications, especially for the field of autonomous robotics. In swarm robotics, teams of small, inexpensive robots are designed to collaborate to achieve tasks beyond the capabilities of any single group member.have at best achieved linear scaling: doubling the number of robots doubles the force output. This means robots may not be suffering from the Ringelmann effect, but they're also not"superefficient". Programming robots with ant-mimicking strategies – such as the weaver ants' force ratchet – could improve their performance and allow machines to become more than the sum of their parts.. And for some animals at least, more really is better. If weaver ants were cooks, it's fair to say they might just make the best broth.
