We studied the collective dynamics of Vibration Driven Vehicles (VDVs) when owing through a narrow constric- tion in a hopper-like geometry. These agents have gained attention recently because of their complex collective behavior and similarities with active matter systems. The proposed system reproduces some of the dynamics of living beings passing through bottlenecks, in particular the power-law distribution for clogging times1,2. Moreover, we found that an increase in the number of agents reduces the ow making a transition to a clogged state3.Reference1 Zuriguel et al. Sci. Rep. 4, 7324 (2014)2 Pastor et al. Phys. Rev.
