Clogging in macroscopic active matter flow through a bottleneck: from pedestrians to robots
The appearance of clogs in the flow of macroscopic active matter through bottlenecks has been widely studied, most notably in pedestrians and sheep. These clogs are characterized by a heavy-tailed survival function for the time intervals between consecutive exits, and seem to require contact among the agents to appear. Another notable characteristic of these systems is the "Faster-is-Slower" effect, by which a higher velocity of the individual agents results in a reduction of flow through the bottleneck.
Despite all previous work, there are still open questions in this field, such as the cause of this "Faster-is-Slower" effect. In our current work, we aim to shed some light into its origin by performing evacuations with programmable robots. This allows us to independently study the effect of the free speed of the agents and pressure they put on the clogs, which allows us to observe clog formation even when they do not push each other.
