She has developed a predictive control model that allows drones to not just react to others in a swarm, but also to anticipate their own movements and predict those of their neighbors. &#8220;Our model gives drones the ability to determine when a neighbor is about to slow down, meaning the slowdown has less of an effect on their own flight,&#8221; says Soria. The model works by programing in locally controlled, simple rules, such as a minimum inter-agent distance to maintain, a set velocity to keep, or a specific direction to follow. Soria&#8217;s work has just been published in <i>Nature Machine Intelligence<\/i>.<\/p>\n<p>With Soria&#8217;s model, drones are much less dependent on commands issued by a central computer. Drones in aerial light shows, for example, get their instructions from a computer that calculates each one&#8217;s trajectory to avoid a collision. &#8220;But with our model, drones are commanded using local information and can modify their trajectories autonomously,&#8221; says Soria.<\/p>\n<p><b>A model inspired by nature<\/b><\/p>\n<p>Tests run at LIS show that Soria&#8217;s system improves the speed, order and safety of drone swarms in areas with a lot of obstacles. &#8220;We don&#8217;t yet know if, or to what extent, animals are able to predict the movements of those around them,&#8221; says Floreano. &#8220;But biologists have recently suggested that the synchronized direction changes observed in some large groups would require a more sophisticated cognitive ability than what has been believed until now.&#8221;\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            A better way to control a swarm of drones\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Enrica Soria et al.
